Does Your iPhone Use As Much Electricity As A New Refrigerator? Not Even Close. – ThinkProgress
The survey of smart phone users was for 4G (because it was 2012 and presumably in the US), resulting in about 12 GB/year of data flows. We need to pair that number with the 4G efficiency of 0.6 kWh/GB (average of the range) to get a consistent estimate of 7.2 kWh/year. Thus, Mr. Mills’ 300 kWh/year for data flows should be 42 times lower, or 7.2 kWh/year.

Mr. Mills gives a electricity intensity range of 2 to 19 kWh/GB, and chooses the lowest value, thus seeming to be a reasonable fellow, but let’s examine that range. 2 kWh/GB is a bit lower than the Swedish average for 3G intensity, but it’s in the same ballpark, so let’s call it 3G. That means he’d need to pair that intensity with data flows for 3G phones, but such data are not easily available.

IEEFA Germany: RWE’s coal phaseout compensation demands defy market prices - Institute for Energy Economics & Financial Analysis : Institute for Energy Economics & Financial Analysis
If market price is the benchmark for compensating the early closure of coal assets, then recent deals indicate that Germany’s coal and lignite power plants and mines have very low value, and make a mockery of compensation claims by Germany’s biggest utility, RWE, under the country’s pending coal phaseout plan.

RWE says it wants to be compensated for the premature closure of its coal power plants in line with the most generous pay-outs of the past, a position that ignores the darkening outlook for coal mining and generation, and which pits the company against genuinely affected mining communities for precious taxpayer funds.

Liebreich: In Energy and Transportation, Stick it to the Orthodoxy! | Bloomberg NEF
The Orthodoxy Window is maintained by a whole ecosystem of supposed thought-leaders, all trying their hardest to avoid having to think uncomfortable thoughts. Industry bodies trumpeting the world’s vital interest in protecting fossil-fuel- and diesel-engine-producing incumbents; respected analysts who are nothing but oil industry shills; right-wing commentators who talk like libertarians but walk like corporatists; bloggers and Twitterati, whose certainty that the energy and transport sectors can never change is inversely proportional to their knowledge. Pity the general public, correctly wary of wrenching change, threatened by this mob each time they think of peeking outside the Orthodoxy Window...

However, there is much more to do. In too many areas the Orthodoxy Window is still tightly shut. For instance, the majority of people I meet still believe the following: the cost of managing intermittency is prohibitive; demand rebounds to eat all the benefits of energy efficiency; industrial processes are inevitably lumbering, inflexible and fossil-fuel powered; long-distance freight can only be carried by dense liquids; those lacking modern energy services would be better off waiting for a centralized grid, rather than using distributed solutions today; advanced biofuels will never work; the answer to every long-term question is hydrogen; self-driving cars will eat the world; England will never win another football World Cup.

Courtier, ex-journaliste, serveuse... Portraits des huit porte-parole des gilets jaunes - Libération
Marine Charrette-Labadie, 22 ans, serveuse en Corrèze

Elle a organisé plusieurs blocages près de Brive en Corrèze. Interrogée par Marianne sur ses motivations, le 4 novembre, elle explique être «plutôt de gauche», mais ne s’être jamais mobilisée auparavant. Son déclic ? «L’examen de son cas personnel […]. Résidant à Voutezac, petite commune située à 25 kilomètres du restaurant où elle travaille, elle dépense chaque mois près de 200 euros de carburant seulement pour aller travailler», raconte notre confrère.

Depuis le début de son engagement, la jeune femme semble très prise par l’organisation du mouvement. Un investissement qu’elle juge parfois ingrat : «C’est très dur d’être pointés du doigt [sur la proximité avec l’extrême droite, ndlr], injuste même. Nous mettons notre vie entre parenthèses pour dire que nous n’en pouvons plus, qu’il est de plus en plus difficile de vivre… Et pour seule réponse, nous récoltons des insultes», confie-t-elle.

A view from the cycle path: electric cars
It made me think: what exactly have we bought today ? Our tank full of fuel came to a bit more than 36 and a half litres. 36.5 l of petrol weighs about 26 kg. Burning that one tank full of petrol will put about 84 kg, a little more than my own weight, of CO2 into the air. That's the effect from just one tank full of petrol, which according to the manufacturer is supposed to be enough to drive around 500 km.

Petrol is amazing stuff. It has an energy content of 9.7 kWh per litre, so today we bought 355 kWh of energy for our 53 euros. The car consumes about 0.7 kWh produces 0.17 kg of CO2 per km driven.

A few years back, someone who set a world record by cycling over 1000 km in 24 hours calculated that his average power output was about 115 W for the entire 24 hours. That's someone at the absolute peak of what is possible, and his body generated about 2.7 kWh over a 24 hour period.

In light of this, I think it's reasonable to say that an averagely strong person doing an 8 hour shift at a physically demanding job would expend no more than 1 kWh per day at work, so we could say that in our tank full of petrol we've bought the equivalent of someone working hard nearly every day for an entire year, including weekends and almost all holidays. This cost just 53 euros. That really is a bargain.

A Nation-Sized Battery | Do the Math
Putting the pieces together, our national battery occupies a volume of 4.4 billion cubic meters, equivalent to a cube 1.6 km (one mile) on a side. The size in itself is not a problem: we’d naturally break up the battery and distribute it around the country. This battery would demand 5 trillion kg (5 billion tons) of lead.
Get the Lead Out!

A USGS report from 2011 reports 80 million tons (Mt) of lead in known reserves worldwide, with 7 Mt in the U.S. A note in the report indicates that the recent demonstration of lead associated with zinc, silver, and copper deposits places the estimated (undiscovered) lead resources of the world at 1.5 billion tons. That’s still not enough to build the battery for the U.S. alone. We could chose to be optimistic and assume that more lead will be identified over time. But let’s not ignore completely the fact that at this moment in time time, no one can point to a map of the world and tell you where even 2% of the necessary lead would come from to build a lead-acid battery big enough for the U.S.

Q&A: What next for UK capacity market after surprise EU ruling? | Carbon Brief
The capacity market is designed to make sure there is always enough supply to meet peak electricity demand, even on cold and dark winter evenings when there is little wind. It covers the electricity market in Great Britain only, with Northern Ireland part of an all-Ireland scheme.

It awards contracts to firms that offer to supply electricity generating capacity during the periods of peak demand between 4pm and 6pm in winter. Firms can offer to turn down electricity demand instead – a process called demand-side response (DSR).

Existing power plants can get contracts for one year at a time, or three years, if they carry out upgrades. New power plants get 15-year deals. Crucially, DSR is only offered one-year contracts. This is why Tempus Energy – a DSR firm – challenged the capacity market approval.

Judicial Office Launches Investigation into Complaint over Fracking Judge with Alleged Oil and Gas Ties | DeSmog UK
An investigation has been launched into allegations the judge who handed three fracking protesters “manifestly excessive” jail sentences has family ties to the oil and gas industry.

Judge Robert Altham sentenced Simon Blevins, Richard Roberts and Richard Loizou to up to 16 months in prison after they were convicted by a jury of causing a public nuisance offence. The protesters had their sentences quashed in an appeal case last week.

Under the Judicial Code of Conduct, judges are expected to disclose personal relationships, social contacts and activities that could cause a bias or a conflict of interest and which put their impartiality into question.

In a statement, the Judicial Conduct Investigations Office (JCIO), an independent body which deals with judicial complaints of misconduct, has confirmed receiving a complaint regarding Judge Robert Altham and added that it will be considered in accordance with the Judicial Conduct Rules.

He said Riyadh was weighing up 30 measures designed to put pressure on the US if it were to impose sanctions over the disappearance and presumed murder of Jamal Khashoggi inside the country’s Istanbul consulate. These would include an oil production cut that could drive prices from around $80 (£60) a barrel to more than $400, more than double the all-time high of $147.27 reached in 2008.

Secret UK push to weaken EU climate laws 'completely mad' | Environment | The Guardian
Benedek Jávor, the vice chair of the European parliament’s environment committee, told the Guardian: “The UK’s proposal to widen ‘flexibilities’ is completely mad and undermines the principle of additionality, as well as the overall ambition of the energy efficiency directive.”

“This approach would risk failure in our efforts to reach even moderately ambitious overall targets, while the higher – and beneficial targets – that we need to strive for could become lost altogether.”...

The EU’s climate goals for 2020 are a staging post to its more ambitious promise to the Paris conference of a 40% emissions cut by 2030.

Europe is expected to easily achieve this, although its CO2 emissions appear to be rising as economic activity picks up, while energy efficiency gains have gone into reverse.

Eurostat figures released last week showed a 1.8% rise in CO2 emissions from fossil fuel use in 2017 after a 0.4% fall the year before. Surprisingly though, the UK was the only EU country to reduce its electricity consumption in 2017.

Pourquoi les agriculteurs n'arrivent pas à réduire leurs émissions de GES
Responsable de 20% des émissions de gaz à effet de serre, l'agriculture fait partie de l'équation de la lutte contre le changement climatique. Mais les derniers résultats de la stratégie bas-carbone française ne sont pas reluisants : en 2016, le secteur affiche un dépassement de 
3% par rapport à l'objectif annuel d'émissions de CO2. Pourtant les solutions sont connues : optimisation de la fertilisation azotée, réduction des consommations d'énergie des bâtiments d'élevage, introduction de légumineuses dans les rotations, développement de l'agroforesterie, recours à la méthanisation, etc. Certaines de ces actions ont même un intérêt supplémentaire : elles améliorent la situation économique des exploitations. C'est le cas de la méthanisation par exemple. Selon la dernière étude de l'Ademe en la matière, les énergies renouvelables permettent aux agriculteurs de diversifier leurs revenus pour des montants allant de quelques milliers d'euros de réduction de leur facture énergétique à plus de 15.000 euros de revenus supplémentaires par an.

The Ranty Highwayman: Nonsense Travels At 25mph
40kph is is 25mph, but a 3% gradient is 1 in 33 - for every 33 metres travelled, one drops 1 metre - that is a pretty steep hill. The other figures range between 12.5mph and 18.75mph. Remember, this is a design standard for trunk roads and motorways and therefore anything designed to this will probably be rural.

These design speeds provide lots of margin for error and will rarely be applicable in an urban situation. Chickwick High Road does not have a gradient of 3%, it's not rural and so 25mph is never going to be a sensible or even an achieveable design speed. Of course, the carriageway of Chiswick High Road is 30mph, but driver speed never seems to feature in the concerns of those who are against providing cycle tracks.

Meet North America’s largest lithium-ion battery storage facility
“Although the Escondido facility is a 30-megawatt system, it’s technically three 10-megawatt systems. It’s one site with three different units that can work together or independently,” he shares. “So CAISO can set one 10-MW unit to do one thing, such as store power, while the other two 10-MW units contribute power to the electric grid or the reserve market”...

Reguly says the project addresses the reliability issues that have previously affected natural gas peaking power plants. “California is really leading the way in regards to the future of transmission,” he adds. “And what’s impressive is that this lithium-ion battery energy storage center, the largest in North America, was completed in a matter of months.”

Going off-grid in the UK | Energy Matters
The solar array I chose as my UK example is on the roof of 10 Mossbank Way, Shrewsbury (data from Sunny Portal). With a capacity of 4kWp (16 Sanyo HIT-H250E01 panels), total 2016 generation of 3,809 kWh and a capacity factor of 10.8% it’s about as average as you can get for a rooftop UK system:...
An off-grid scenario that leaves Mossbank without electricity for almost a third of the year is clearly not acceptable, so we must evaluate other options. Can we eliminate blackout hours by increasing storage capacity? Adding another Powerwall reduces blackout hours from 2,769 to 2,678 and adding ten more lowers them to 2,323. Clearly adding more Powerwalls is not going to solve the problem. We need another option.

'No shame': how the Trump administration granted big oil's wishlist | Business | The Guardian
in a “wishlist” drawn up by the American Petroleum Institute (API), the leading lobby group for US oil and gas companies.

In a document called “comments on specific regulations” sent to the Environmental Protection Agency (EPA) in May, API highlighted eight key changes it wanted to ease the regulation of air and water pollution. An analysis shows that the EPA has now so far either partially or wholly delivered on six out of these eight key demands within the first year of the Trump administration, which solicited input on government rules from a number of trade groups.

‘Death spiral’: half of Europe’s coal plants are losing money | Environment | The Guardian
Carbon Tracker analysed the revenues and operating costs of all the EU’s coal plants and found 54% are already loss making today. All coal power must be phased out if the EU is to meet the goals of the global Paris climate change agreement, but the current business plans of the utilities would see just a quarter of plants closed.

The new report estimates that closing all the plants by 2030 will avoid losses of €22bn for the plant’s owners, either shareholders or governments. Germany hosts the largest number of unprofitable coal plants and the losses avoided by early closure there total €12bn, with both RWE and Uniper highly exposed. Plans put forward to close German plants have been delayed by the failure of talks to form a new coalition government.

“The changing economics of renewables, as well as air pollution policy and rising carbon prices, has put EU coal power in a death spiral,” said Matt Gray, co-author of the Carbon Tracker report. “Utilities can’t do much to stop this other than drop coal or lobby governments and hope they will bail them out.”

Natural gas emissions will blow Europe's carbon budget at current levels | Environment | The Guardian
Governments have drastically underestimated methane emissions from natural gas and will miss the Paris agreement’s goal of limiting global warming to 2C unless they urgently scale down its use, a major new study has found.

Continuing natural gas emissions at present levels will add 0.6C to global warming and, with other fossil fuel use, exhaust Europe’s carbon budget – the amount it can safely and fairly emit – in less than a decade, says the report by the Tyndall Centre for Climate Change Research.

It concludes that Europe must phase out all fossil fuels including gas by 2035 and decrease emissions by 12% per year – far beyond its current ambitions – to keep to the Paris 2C pledge.

EU countries, including the UK, have committed to burn more natural gas as a “bridging fuel”, because it offers a baseline alternative to wind and solar on cloudy and windless days, and because it emits less carbon dioxide than coal.

But the report’s authors find that there is “categorically no role” for new gas, oil or coal production, because of their high CO2 and methane emissions.

One Bitcoin Transaction Now Uses as Much Energy as Your House in a Week - Motherboard
That problem is carbon emissions. De Vries has come up with some estimates by diving into data made available on a coal-powered Bitcoin mine in Mongolia. He concluded that this single mine is responsible for 8,000 to 13,000 kg CO2 emissions per Bitcoin it mines, and 24,000 - 40,000 kg of CO2 per hour.

As Twitter user Matthias Bartosik noted in some similar estimates, the average European car emits 0.1181 kg of CO2 per kilometer driven. So for every hour the Mongolian Bitcoin mine operates, it's responsible for (at least) the CO2 equivalent of over 203,000 car kilometers travelled.

As goes the Bitcoin price, so goes its electricity consumption, and therefore its overall carbon emissions. I asked de Vries whether it was possible for Bitcoin to scale its way out of this problem.

Electric Vehicles, Batteries, Cobalt, and Rare Earth Metals  - Union of Concerned Scientists
A lot of these warnings have been incorrectly categorized under “EVs and rare earth metals.” Though neither lithium nor cobalt are rare earth metals, and rare earth metals aren’t nearly as rare as precious metals like gold, platinum, and palladium, there are important issues surrounding the production of lithium-ion batteries that must be acknowledged and addressed.
Cobalt, a bluish-gray metal found in the Earth’s crust, is one of today’s preferred components used to make the lithium-ion batteries that power laptops, cell phones, and EVs. Cobalt is mined all over the world, but 50 to 60 percent of the global supply comes from the Democratic Republic of Congo (DRC), which has a poor human rights track record. According to UNICEF and Amnesty International, around 40,000 children are involved in cobalt mining in DRC where they make only $1 – $2 USD per day. DRC’s cobalt trade has been the target of criticism for nearly a decade, and the U.S. Labor Department lists Congolese cobalt as a product it has reason to think is produced by child labor. More troubling, cobalt demand has tripled in the past five years and is projected to at least double again by 2020.

Guest post: Authors respond to misinterpretations of their 1.5C carbon budget paper | Carbon Brief
We estimated the remaining “carbon budget” – the amount of CO2 that could be released from 2015 onwards – consistent with meeting the most ambitious part of the Paris Agreement long-term temperature goal, namely “pursuing efforts to limit global warming to 1.5C above pre-industrial levels”.
What were the conclusions?

That the carbon budget “likely” (see note 1, below) to be consistent with 1.5C of human-induced warming is about 200-240 gigatonnes of carbon (GtC, or 730-880GtCO2) from the beginning of 2015, depending on how rapidly we cut back on non-CO2 contributions to global warming. Here, we interpreted 1.5C as being 0.6C of warming above the present decade (2010-2019), using an estimate of human-induced (“attributable anthropogenic”) warming (note 2) by 2015 of 0.93C above mid-19th century values (see discussion below on our choices of reference periods and datasets). This carbon budget represents around 20 years of present CO2 emission levels, equivalent to reducing emissions in a straight line to zero by 2055.

Hurricane Harvey raises awkward questions over US energy ambitions
With domestic consumption down slightly and exports surging, US oil import dependency plunged to a mere 25 per cent last year from as high as 60 per cent in 2005. On paper, that sounds like a big step for energy security. But the flipside is higher reliance on potentially vulnerable Gulf Coast infrastructure. On the downstream side, operating refining capacity in coastal Texas and Louisiana jumped by almost a quarter from about 7m barrels per day on the eve of Katrina to 9.7 bpd at the latest count, even as capacity elsewhere edged down, lifting the Gulf’s share of US refining activity to nearly half of the total.

The same dependency on the Gulf applies for logistics. Rising exports and falling imports turned the US into a net exporter of gasoline (including both finished product and blending components) last year. Roughly 90 per cent of gross exports came from the Gulf. The region leads the US surge in virtually all other types of oil exports by a wide margin: as of 2016, the Gulf accounted for 54 per cent of US exports of crude, 68 per cent of natural gas liquids, 86 per cent of diesel and 75 per cent of jet fuel — a much higher share of a much higher total.

One of the unexpected consequences of the US shale boom is the rising co-vulnerability of its increasingly complex and integrated energy system. Even inland plays such as the Permian, the shale industry’s star performer, seemingly out of harm’s way, have become exposed to the risk of weather disruptions at coastal refineries, pipelines and export facilities on which they depend for market access.

Getting Rid of Wind Energy in Europe | Energy Matters
France was the second largest electricity exporter in Europe in 2016. Germany and France form at block with about 10% surplus of electrical energy. This surplus is conveyed to other European countries. Safe operation of the highly meshed European AC power grid is a complicated matter. Due to the variability of wind and solar power, the grids are often operated close to the security limits.

Wind power curtailment is regularly necessary for relieving the pressure on the grids. It is known in Germany as redispatch. The cost of redispatch has been rapidly increasing since 2013 (fig. 2). The redispatch cost is still small compared with the total support for renewable energy in Germany, but the question is if the trend lasts.

Analysis: Switch to electric vehicles would add just 10% to UK power demand | Carbon Brief
Note that EVs offer CO2 savings even under relatively CO2-heavy electricity grids including coal-fired generation. This is because EVs are more efficient than combustion-engine cars. Similarly, the CO2 associated with manufacturing EV batteries is more than offset by savings during EVs’ lifetimes.

A comprehensive literature review from the International Council on Clean Transportation (ICCT) says EVs offer CO2 savings of 40-50% compared to average combustion engine vehicles. This includes full lifecycle emissions including manufacture, use and electricity generation, based on an EU average grid mix. This means EVs could cut global emissions by 1.5 billion tonnes of CO2 per year in 2050, a second ICCT study says.

Factcheck: How much power will UK electric vehicles need? | Carbon Brief
In one scenario, where 100% of cars go electric but smart charging and shared autonomous vehicles help manage the impact on the grid, peak demand could be limited to around 6 gigawatts (GW) in 2050. This is equivalent to 10% of the current 60GW peak demand on a cold winter’s day...
scenarios suggest that with 23-25m EVs in 2050, peak demand could be as high as 18GW, or as low as 6GW, depending how well managed the roll out is.

Au final, ces calculs amènent aux valeurs courantes de cout CO2 par KWh.
Le cout CO2 d'une éolienne est pour EDF entre 3 et 22g par KWh, plus que le cout CO2 d'une centrale nucléaire bien souvent (6 à 10g/KWh), mais effectivement moins que la moyenne globale francaise.

What does ‘Clean Coal’ CCS Failure in U.S. Mean for Meeting Our 2°C Climate Goals? | DeSmog UK
The concept of “clean coal” was dealt a significant blow as Southern Company announced last week that it was suspending its coal gasification project in Mississippi.

The project was meant to be America’s flagship example for commercial-scale carbon capture and storage (CCS) technology. It was going to be a way to keep burning coal, except without the polluting carbon dioxide emissions.

The failure of this “clean coal” experiment has impacts beyond the US though as the world continues to wait for CCS technology to take off at scale.

CCS is the process of scrubbing carbon dioxide emissions from power plants and other industrial sources and storing them deep underground. The Kemper plant was attempting to use CCS in the power generation process as it converted coal into natural gas.

A New Problem for Keystone XL: Oil Companies Don’t Want It - WSJ
TransCanada has spent $3 billion to date on Keystone XL, much of it on steel pipe, land rights and lobbying. Completed, the pipeline would travel 1,700 miles from Alberta to Steele City, Neb., where it would link up with existing pipelines that run to the Gulf Coast.

The lack of interest has put the pipeline’s fate in jeopardy. The company, based in Calgary, Alberta, has said it wants enough customers to fill 90% of Keystone’s capacity before it proceeds...

Back then, the price of oil had surpassed $130 a barrel, producers were rushing to pump as much as possible and refiners were itching to secure steady supplies. Today, oil is trading around $45 amid a global supply glut caused in part by the emergence of American shale drillers.*

Refiners want the flexibility of being able to buy oil from wherever it is cheapest. In a world awash in low-price oil, Canadian crude doesn’t look as attractive as it once did. Many refiners thus far are unwilling to commit to long-term deals for Canadian crude, say people familiar with the matter.

Cut fossil fuel use dramatically: Shell-backed climate report
The falling costs of renewables means that increasing shares of overall energy use could be decarbonised through electrification, the report says. Around 10-20% of fossil fuel use could be eliminated in this way, using electric vehicles and heating.

Across the global economy, a “step change in energy productivity” is required, with improvements in the amount of energy needed to generate wealth rising from 1.7% per year to 3%. To achieve this “energy productivity revolution”, more efficient devices and vehicles will have to be combined with deeper structural change, such as more efficient urban design.

Use Of Alternative Jet Fuels Won't Allow For Significant Emissions Reductions, Study Finds | CleanTechnica
The problems? Other than costs, the issues are: 1) when land use change effects are factored in, vegetable oil–based feedstocks usually have a higher carbon intensity than conventional jet fuel does, and 2) with regard to agricultural waste feedstocks, the supply simply isn’t there (and won’t be there) to offset significant amounts of conventional jet fuel use.

The study was performed with the intent of evaluating the possibility of the aviation sector achieving carbon-neutral growth by or after 2020 (despite the sector’s expectation of strong growth over the coming decades).

Here’s more on the study from the ICCT: “The feedstocks that provide the largest carbon reductions in AJFs are constrained in their supply and will likely also be in demand from competing sectors such as road transport. Estimates for maximum availability of sustainable AJF feedstocks reveal that it would be impossible to substitute total jet fuel consumption with AJF up to 2050 or attain carbon-neutral growth through AJF only. Although estimated demand for jet fuel amounts to 24–37 EJ in 2050, the absolute maximum amount of lignocellulosic biofuel that could be available for the aviation sector is around 4 EJ in 2050

The causes of the recent decrease in US greenhouse gas emissions | Energy Matters
According to these results the US electricity sector is in fact responsible for only about 30% of total US GHG emissions – a good illustration of the futility of concentrating on cutting electricity sector emissions while ignoring emissions from other sectors.

Between 2007 and 2014 total US annual GHG emissions fell from a peak of 7,370 to 6,826 million tonnes. This 544 million-tonne decrease is in the same range as the UK’s total annual GHG emissions – i.e. not peanuts. Figure 2, which plots emissions by sector, shows how the different sectors contributed to the decrease (data again from EPA).

An update on the Energiewende | Energy Matters
The reason renewables have had no detectable impact is that the added generation has gone towards filling increased demand and replacing nuclear generation rather than generation from gas, coal and lignite, which remains about the same as it was in 1990 (Figure 4, data from Clean Energy Wire). This is in line with Germany’s goal of shutting down its nuclear plants but will of course do nothing to reduce emissions:

UK 'need not fear electricity blackouts' says ex-National Grid boss - BBC News
Generating margins were forecast to be tight for this winter, but there has been no problem, despite a long cold windless spell during which wind energy has produced around 1% of electricity demand. The highest daily percentage of wind power was over 20%.

Mr Holliday, who was chief executive of National Grid until July 2016, forecasts that all future talk of blackouts will be made redundant by a revolution in flexible electricity, with customers using power when it is cheapest.

One current weapon at National Grid's disposal is a contract for flexible supply with firms which don't manufacture continuously.

Why electric cars are only as clean as their power supply | Environment | The Guardian
the Union of Concerned Scientists – which works to raise awareness of climate change – believes that despite a fossil-fuel-dependent grid, electric cars are, on balance, better for the environment.

“There are no areas of the country where electric vehicles have higher global warming emissions than the average new gasoline vehicle,” the campaign group claims in its paper, State of Charge, which calculates the emissions equivalent of an electric vehicle using the makeup of the local energy supply. Using UCS’s formula, a Tesla Model X charging in the Los Altos Whole Foods garage achieves a fuel efficiency equivalent to 81 miles per gallon – far higher than a gas-powered car.

Yet not all scientists agree with that approach. “All of the action is in the hourly,” says Graff Zivin. It’s not only the region that an electric vehicle plugs into that matters. The hour of the day is equally critical. “The cheapest power is not the greenest power.”

In California, the cheapest power is produced at night, mostly from natural gas, hydroelectric dams and nuclear. Night is when many people will charge their electric cars. However, the greenest power gets generated during the day

Blackout: the sequel | Energy Matters
Scotland has become a serial electricity importer as was to be expected. In Jan-Feb imports were 2,733 MWh. This has risen to 227,002 MWh in Oct-Nov (to date), an increase by a factor of 83.
Imports of 1000 MW or more are commonplace peaking at 2552 MW on 23 November following the reactor trip at Torness.
Oct-Nov was less windy than Jan-Feb, which was particularly stormy and wind never got close to the presumed 3500 MW curtailment level (dashed line lower panel). However, exports seem to be curtailed at a lower level of 2600 MW. This is difficult to explain other than wind did not get above this level.
Exports and wind output are still correlated but with one notable exception. From 11 to 17 Nov there was a block of exports not correlated with windy conditions. We can speculate that it was windy in Scotland but not in England at this time.
The reactor trip at Torness was followed by a sudden fall in wind, which just goes to show how events can conspire against grid integrity.

The European Blackout Risk | Energy Matters
At 2000 hours Central European Time on February 8, 2012 combined electricity demand in the UK, France and Germany peaked at a high of 231GW during a winter cold snap. This caused no serious problems at the time, but the UK, France and Germany could have a combined total of as little as 210GW of capacity on-line this winter, and if another 231GW demand peak coincides with 210GW of available capacity the alternatives will be either large-scale “demand side” management (i.e. paying lots of industries and businesses to shut down) or blackouts.

In this post we will look at how these conclusions were arrived at and also at some of the uncertainties that make it so hard to predict blackout risks. The chief uncertainties in this case are a) how cold might it get, b) will the wind be blowing when and if it does get cold, c) how much of the French nuclear fleet will be down for inspection at the time and d) how many French households will turn their electric heaters up to “high”, as many of them did in 2012.

France’s Nuclear Storm: Many Power Plants Down Due to Quality Concerns
With over half of France’s 58 reactors possibly affected by “carbon segregation,” the nation’s nuclear watchdog, the Autorité de Sûreté Nucléaire (ASN) has ordered that preventative measures be taken immediately to ensure public safety. As this story goes into production in late October, ASN has confirmed that 20 reactors are currently offline and potentially more will shut down in coming weeks.

The massive outages are draining power from all over Europe. Worse, new questions continue to swirl about both the safety and integrity of Électricité de France SA’s (EDF’s) nuclear fleet, as well as the quality of some French- and Japanese-made components that EDF is using in various high-profile nuclear projects around the world.

EDF’s nuclear power plants (NPPs) provide up to 75% of France’s power needs. Its NPPs are spread out over 19 sites and include 34 900-MW units, 20 1,300-MW units, and four 1,450-MW units. As the fleet suffered through shutdowns, inspections, and reviews, production fell in September to its lowest level since 1998—just 26.6 TWh, according to French grid operator Reseau de transport d’electricite.

Energy Outlook: Is the US Really Energy Independent?
Toward the end of Sunday night's presidential debate I was startled to hear Secretary Clinton reply to an audience question by stating, "We are now for the first time ever energy-independent." If the price of oil were $100, rather than $50, that might have constituted a "Free Poland" moment, recalling President Ford's famous gaffe in a 1976 debate.

This point is likely to get lost in the dueling fact-checking of both candidates' numerous claims, but while the overall US energy deficit has fallen from about a quarter of total consumption (net of exports) in 2008 to just 11% in 2015, we still import 8 million barrels per day of oil from other countries. That includes over 3 million barrels per day from OPEC, a figure that has been growing again as US oil and gas drilling slowed following the collapse of oil prices in late 2104.

Oil has always been at the heart of our notions of energy security and energy independence, because it is our most geopolitically sensitive energy source and the one for which it is hardest to devise large-scale substitutes. So although the US is certainly in a better overall position than it has been in decades, with progress on multiple aspects of energy, it is not yet energy independent, especially where it counts the most.

An energy first as UK successfully transmits data via national electricity grid | Environment | The Guardian
The new data system, created using telecoms technology by Reactive Technologies (RT) and now successfully tested on the UK’s National Grid, could also allow the optimum use of intermittent renewable energy, an important feature given the fast-rising proportion of green energy on the grid.

Unlike the smart meters being rolled out by the UK government, the new system is anonymous, with no data on household energy use being collected and therefore avoiding concerns about privacy.

The system uses new technology to send messages through national electricity cables to any appliances with a smart plug connected to the mains, asking it to adjust its energy use. In the home, this could mean allowing the temperature of a freezer to increase by 0.5C to cut demand or turning up a water heater at 1am to utilise spare renewable energy.

In the commercial sector, where the technology will be first rolled out, it could mean water company pumps are used at specific times or an office air-conditioning system is adjusted.

Recalculating the Climate Math | New Republic
the new new math is even more explosive. It draws on a report by Oil Change International, a Washington-based think tank, using data from the Norwegian energy consultants Rystad. For a fee—$54,000 in this case—Rystad will sell anyone its numbers on the world’s existing fossil fuel sources. Most of the customers are oil companies, investment banks, and government agencies. But OCI wanted the numbers for a different reason: to figure out how close to the edge of catastrophe we’ve already come.

Scientists say that to have even a two-thirds chance of staying below a global increase of two degrees Celsius, we can release 800 gigatons more CO2 into the atmosphere. But the Rystad data shows coal mines and oil and gas wells currently in operation worldwide contain 942 gigatons worth of CO2. So the math problem is simple, and it goes like this:
942 > 800

Nuclear power is risky and expensive; here's a better idea | UK news | The Guardian
The momentum behind the revolution is straightforward: cost. While renewable energy and other energy technologies are plummeting in price, nuclear power continues its historical trend of getting ever more expensive. Even if the UK negotiates a sharp cut in the subsidies for Hinkley, it still could not be built before 2026 at the earliest. By then, a capacity crunch will have hit the UK as old power stations close.

Hinkley puts a lot of generation capacity in one plan , which is very risky given the financial, legal and technical obstacles it faces. EDF, the French company leading the project, is taking on considerable financial risk, with Martin Young, an energy analyst at investment bank RBC Capital Markets, saying the project “verges on insanity”.

deployment of nuclear power has in the past depended upon a combination of three factors 1) the size and level of technology development of any country (the leading producers in 2015 were the USA, France, Russia and China) 2) the desire to acquire nuclear weapons that may be linked to large advanced countries wanting to defend themselves and 3) a shortage of fossil fuels (France, Ukraine, Slovakia, Hungary, Slovenia etc. have the greatest penetration of nuclear in power generation). Let’s begin by looking at the 30 countries that have domestic nuclear power capacity (Figure 1).

El Hierro completes a year of full operation | Energy Matters
The answer is simple. Intermittent renewable energy is not going to replace dispatchable fossil fuel generation without adequate energy storage backup, and since the amount of energy storage needed is almost always prohibitive it follows that an energy future based entirely on intermittent renewables is not a realistic prospect. As discussed at length in previous posts the only way to integrate significant amounts of intermittent renewable energy with the grid is by maintaining enough dispatchable capacity to cover demand when the wind doesn’t blow and the sun doesn’t shine. GdV has in fact already effectively defaulted into this operating mode.

The unexpected difficulties experienced in stabilizing the El Hierro grid at high wind penetration levels also come as an unpleasant surprise. It is not clear to what extent larger and more stable grids will experience similar problems, but the assumption that any problems of this type can be easily overcome with appropriate technology may require review.

Here’s what publicly owned energy would actually cost – and why the stockbrokers got it wrong | openDemocracy
A substantial majority of people want to see the UK’s electricity and gas services in public ownership. We think that the private companies are charging us far too much; we want to move much faster towards generating electricity from renewable sources like wind and solar; and we want the whole system to be transparent and accountable to the public instead of shrouded in corporate secrecy and double-speak.

When Jeremy Corbyn supported this view during his leadership campaign in August 2015, the mainstream media didn’t discuss any of these issues – they just insisted we couldn’t afford it. The Daily Telegraph, the Guardian and the Sun all triumphantly headlined a claim from city stockbroker Jefferies that Corbyn’s scheme would cost £124 billion or £185 billion, and we obviously can’t afford that, and so we have to put up with privatised energy for ever.

Unfortunately, the stockbroker’s claim was about as accurate as the forecast of a Burnham victory. A far more realistic estimate is that compensation could cost about £24-36 billion, in return for which we would save over £3 billion every year, mainly by losing the burden of shareholders’ dividends. That’s a return of nearly 10% or more – not a bad investment, by any standards

Le véhicule électrique doit être utilisé intensément pour maximiser le gain environnemental
Au plan énergétique, "la consommation (…) d'un VE est globalement proche de celle d'un véhicule diesel", relève l'Ademe. Car si sa chaîne de traction présente un excellent rendement énergétique, celui de la production électrique nécessaire pour recharger ses batteries est faible. En revanche, l'avis souligne l'intérêt du VE concernant la réduction de la dépendance au pétrole importé, d'autant plus que le mix électrique intégrera une part croissante d'énergies renouvelables (EnR). Un avantage qui se traduit économiquement par une baisse de la facture énergétique et, au plan environnemental, par une moindre sollicitation des ressources fossiles.

Le VE a des impacts négatifs sur l'environnement en termes d'acidification des milieux et d'eutrophisation des eaux, lors de sa phase de fabrication principalement. "Sur le cycle de vie du véhicule, ces impacts sont toutefois du même ordre de grandeur pour un VE que pour un véhicule thermique", affirme l'Ademe. Mais, celle-ci ne parle pas des matériaux nécessaires à la production des batteries des VE, notamment le lithium et les terres rares. L'avis souligne en revanche que l'utilisation en seconde vie et le recyclage des batteries permettent de diminuer ces impacts environnementaux.

One Step Closer to Blackouts | Energy Matters
The Scottish supply is now based on nuclear, wind and imports with a little hydro and gas on the side. I think nuclear and wind is likely the worst combination for any grid that no sane power engineer would design. Variable and intermittent wind does not sit well with constant, base load nuclear power...
Clearly, national governments, power generation and distribution companies should do everything they can to safeguard against blackouts. It appears that what is happening in Scotland is the exact opposite where Scottish Power (a subsidiary of Spanish Iberdrola) has made a commercial decision to close Longannet forced by energy policy both N and S of the border. Scottish politicians seem more interested in scoring political points out of this event than safeguarding the best interests of the Scottish people. Had the NE USA blackout of 2003 occurred in January instead of August, the death toll may have been many thousands as old and vulnerable people would have died from the cold.

Auto électrique : la grande arnaque
L’idée d’une voiture neutre en CO2 a pourtant été battue en brèche. En novembre 2013, une étude de l’ADEME analyse les émissions de gaz à effet de serre sur l’ensemble du cycle de vie de la voiture électrique. Le résultat est marquant : une voiture électrique « rentabilise » son impact CO2 à partir de 50 000 km en France, et de 100 000 en Allemagne – une différence qui s’explique par l’alimentation électrique au charbon, à hauteur de 44 % outre-Rhin.

Nouveau calcul : « Cela revient à une moyenne de 15 kilomètre par jour, 365 jours par an, pendant 10 ans. En dessous, la voiture électrique est moins efficiente en CO2 qu’une voiture thermique », dit Stéphane Lhomme. Avec l’Observatoire du nucléaire, il a récemment obtenu du Jury de déontologie publicitaire le retrait des adjectifs « propres », « vert » ou « écologique » qu’utilisaient les constructeurs automobiles pour qualifier la voiture électrique.

One potentially promising new example of a smart North Sea combination of renewable investment with oil and gas production is to use existing offshore installations as locations for new conversion and storage units that are used to enhance the business case and market potential of nearby offshore wind energy. The reason this concept makes sense and could help optimise the energy system is that on the one hand the installations and connecting grids are already there and on the other hand the renewable sources have to cope with intermittency, so backup and storage improves their long-term business case.

Biggest wind turbines in world
Over the last five years, there has been a large amount of development in terms of raising the capacity of large wind turbines. Much of this came out of a large number of offshore projects that were put out to tender around 2010. In the UK alone 33GW was supposed to come online offshore. But since then, a significant percentage of this has been cancelled.

Like the projects, many of these new large wind turbines stayed on the drawing board. Some of those listed have only made it to the prototype stage. Taking wind turbines above the 5MW limit is an expensive business even for international conglomerates.

One analysis shows that if seaweed farms covered 9% of the ocean they could produce enough biomethane to replace all of today’s needs in fossil fuel energy, while removing 53 gigatonnes of CO2 (about the same as all current human emissions) per year from the atmosphere. It could also increase sustainable fish production to provide 200kg per year, per person, for 10 billion people. Additional benefits include reduction in ocean acidification and increased ocean primary productivity and biodiversity. Many of the technologies required to achieve this are already in widespread use, if at a comparatively minuscule scale.

Paris attacks - COP21 and the war on terror - The Ecologist
As the FT put it last week in an article titled 'Isis Inc: how oil fuels the jihadi terrorists', "Oil is the black gold that funds Isis' black flag - it fuels its war machine, provides electricity and gives the fanatical jihadis critical leverage against their neighbours ...

"Estimates by local traders and engineers put crude production in Isis-held territory at about 34,000-40,000 bpd. The oil is sold at the wellhead for between $20 and $45 a barrel, earning the militants an average of $1.5m a day ...

"While al-Qaeda, the global terrorist network, depended on donations from wealthy foreign sponsors, Isis has derived its financial strength from its status as monopoly producer of an essential commodity consumed in vast quantities throughout the area it controls. Even without being able to export, it can thrive because it has a huge captive market in Syria and Iraq."

But ISIS's ambitions surely don't stop there. Its aim is to consolidate its hold of the regions it already occupies, extend its empire to new regions and countries, and establish a Caliphate whose power and income will largely derive from oil. So the last thing it needs is a global climate agreement that will, over time, limit global consumption of fossil fuels.

Top Economies to Double Use of Renewables by 2030 | Offshore Wind
Renewable energy supply is set to double collectively in eight major economies by 2030, 18 percent higher than previously projected growth rates, spurred on by new national climate and energy plans, according to new analysis by World Resources Institute (WRI).

WRI’s analysis, Assessing the Post-2020 Clean Energy Landscape, looks at plans from eight of the 10 largest greenhouse gas emitters—Brazil, China, European Union, India, Indonesia, Japan, Mexico and the United States—and finds that their cumulative clean energy supply will jump from approximately 9,000 TWh in 2012 to 20,000 TWh in 2030. This increase is equivalent to all of India’s current energy demand, WRI says.

Germany's electricity will be 33% Renewable in 2015
On July 25, 2015, Germany obtained 78% of its’ electricity from renewable sources. That was a new record, albeit for a single day. Up until now, the European leader has not produced more than 27% green energy in a year. According to a joint press release from the Centre for Solar Energy and Hydrogen Research Baden – Württemberg ( ZSW ) and the German Association of Energy and Water Industries ( BDEW ), Germany’s electricity will be 33% Renewable in 2015...
Germany is expected to produce around 193 billion kilowatt hours (billion kWh) of electricity from solar, wind and other renewable sources. That’s about one fifth more than the 161 billion kWh, or 27% of gross electricity consumption, in 2014.

ORNL tires-to-carbon technology licensed to RJ Lee Group | EurekAlert! Science News
The technology turns rubber sources such as tires into carbon black composites through a proprietary pretreatment process...
When ORNL researchers tested the recovered carbon in anodes of lithium-ion batteries, the laboratory-scale coin cells had a higher capacity and faster charging rates than that of conventional graphite batteries. Using the carbon black composites as a lower cost alternative to graphite could potentially reduce the cost of lithium ion batteries by 10 percent.
