Li-air battery could make oil obsolete in ten years

The Ecologist

23rd November 2015

Sooner than it takes to build a nuclear power station, lithium-air batteries could be helping wind and solar to make coal, oil and nuclear obsolete, say Cambridge scientists. Five times lighter and five times cheaper than current lithium batteries, Li-air would open the way to our 100% renewable future. more...

'QE for climate' is the win-win solution for COP21

Dr. Matthias Kroll

25th November 2015

The governor of the Bank of England recently argued that the risk to the stability of the financial system from climate change is a responsibility of central banks, writes Matthias Kroll. They can begin by using QE - 'quantitative easing' - to finance the Green Climate Fund, and so stimulate the economy, rescue the climate, and save the global financial system. more...

Lights out? Amber Rudd's disastrous absence of an energy strategy

Oliver Tickell

18th November 2015

Amber Rudd's speech today exposes her total failure to assemble a coherent energy strategy, writes Oliver Tickell. It reveals the increasingly certain failure to meet EU renewable energy targets, proposes a new tax on wind and solar generation, and leaves the country facing the real prospect of lights going out in the next decade. The one hard policy? To maximise oil and gas recovery. more...

Weeks before COP21, G20 fail the climate challenge

Oliver Tickell

16th November 2015

In the run-up to the COP21 climate summit in Paris the G20's Antalya Communiqué is weaker on climate, fossil fuel subsidies and support for renewable energy than the G20's 2009 Pittsburgh Statement made shortly before the failed COP15 in Copenhagen six years ago. more...

Britain's race for the climate abyss - only we can stop it now!

Alan Simpson

13th November 2015

The government's policies on climate, energy and industry are not merely stupid, writes Alan Simpson. The repeated cuts to renewables and energy efficiency, combined with limitless largesse to fossil fuels, has reached the point of insanity in the face of the UK's legal obligations and the growing climate crisis. Only we, the people, can end the madness. more...

George Osborne must back down on community energy tax

Georgina Matthews

11th November 2015

Surprise changes to the Finance Bill in its third reading have withdrawn tax benefits for investors in community renewable energy projects, writes Georgina Matthews. While some societies are rushing to complete their fund-raising by the end of the month, others have been forced to close. If these measures are not withdrawn, a small but flourishing sector will be at risk. more...

Facing legal action, strong support for solar and wind, Rudd refuses to reverse cuts

Oliver Tickell

10th November 2015

Despite strong public support for wind and solar power in an official survey published today, the UK's likely failure to meet its EU renewable energy target, and an impending legal challenge, Energy Secretary Amber Rudd today told MPs she would not be reversing recent cuts, writes Oliver Tickell. more...

With floating platforms, offshore wind cost set to plunge

Paul Brown

11th November 2015

Floating wind turbines offer huge falls in the cost of offshore wind power, writes Paul Brown, and could be generating power in UK waters at well under the cost of new nuclear by 2020, provided adequate support. more...

Leaked letter: Rudd admits 25% green energy undershoot, misled Parliament

Oliver Tickell

9th November 2015

A letter from Energy Secretary Amber Rudd leaked to The Ecologist shows that she misled Parliament by promising the UK was 'on course' to deliver on its renewable energy targets - when in fact there is a delivery shortfall in 2020 of almost 25%. Her plan to fill the gap relies on more biofuels, buying in green power and 'credits' from abroad - everything but wind and solar. more...

A clean, green energy future beckons!

Dave Elliott

5th November 2015

The world could soon be generating all its electricity from renewable sources, writes Dave Elliott, by harnessing diverse technologies for generation, grid balancing and energy storage. Add to that the use of power surpluses to make fuels, and it could even be feasible to make all our energy - not just electricity - renewable. A clean green future beckons. more...

Batteries and renewables - believe the hype!

Helle Abelvik-Lawson / Greenpeace Energydesk

5th November 2015

What's the new 'big thing' in energy? Of course, cheap, abundant solar power is very new and very big. But to make it work on a really large scale we need to be able to store its energy to use when we need it, not just when the sun is shining. Soon the batteries will be there to make that possible - at a price we can afford. And that will be a very big thing, indeed. more...

With 50 times more solar power on a 'net metering' basis than now (5% vs 0.1%), electricity costs in Pennsylvania would fall by $25 per customer. Business with solar panels in Harleysville, PA. Photo: Montgomery County Planning Commission via Flickr (CC B

Solar power is good for consumers, good for utilities

Richard Flarend, Pennsylvania State University

30th October 2015

An analysis of power prices in the US state of Pennsylvania shows that if solar power increased from the 0.1% of electricity it supplies now, to 5%, then all customers would save $25 a year. Far from 'net metering' for solar being a 'burden' as utilities claim, it makes money for them, and their customers! more...

UK-China nuclear deal won't keep our lights on

Oliver Tickell

21st October 2015

The UK's plan to get China to build and finance new nuclear power stations is based on a wish and a prayer, writes Oliver Tickell. There is no reactor design, including new Chinese ones, that we can depend on to fill our impending power generation gap. This time, the last one out won't even have to turn out the lights. more...

Wind and solar's £1.5 billion electricity price cut

Oliver Tickell

19th October 2015

The effect of wind and solar generation in the UK is to push down wholesale power prices, writes Oliver Tickell, taking over £1.5 billion off our bills in 2014 - that's 58% of the subsidies paid to renewable generators. Keep it up and the benefit will rise to over 100% of cost. more...

China's smog kills over a million each year - but there's blue skies ahead

Oliver Wild, Lancaster University

19th October 2015

China's smog is an increasing cause of public discontent, writes Oliver Wild - and no wonder! New research shows that the country's air pollution is killing over a million people every year. Thanks to China's geography the problem is hard to solve, but the rapid rise of renewables and the slow demise of coal do offer the promise of cleaner, healthier future. more...

Hydrogen car price breakthrough: it's the platinum

The Ecologist

14th October 2015

Hydrogen cars - and the fuel cells that drive them - are about to get a whole lot cheaper thanks to a redesign of the platinum catalyst that makes them work, writes Oliver Tickell. By inserting atom-sized holes into the precious metal's surface, its activity can be trebled. more...

Making sense of the UK's muddled energy policy - is it all about nuclear weapons?

Philip Johnstone & Andy Stirling

14th October 2015

On the face of it, the UK's policy to pursue nuclear power at all costs, while destroying the renewable energy sector, is totally illogical, write Philip Johnstone & Andy Stirling. But then it may make perfect sense - if only you accept that it's really all about maintaining the country's role as a nuclear weapons state for generations to come. And the 'deep state' has a way of getting its way. more...

Wind turbines and solar panels into nuclear weapons: the UK's new industrial strategy?

Dr Stuart Parkinson

15th October 2015

The UK government is punishing renewable energy for its success in generating 25% of the country's electricity, writes Stuart Parkinson. But there's no austerity when it comes to the bloated military-nuclear industrial sector, no matter how egregious its failures or extreme its cost overruns. Our future prosperity is being sacrificed - and its costing taxpayers billions. more...

UK rigging power market against clean energy

Alex Kirby

7th October 2015

Ecotricity boss Dale Vince has accused the government of rigging the electricity market, writes Alex Kirby, by showering fossil fuels and nuclear power with huge subsidies, while taxing renewables and insisting they must 'stand on their own two feet'. more...

Dieselgate - our wake-up call for new car technologies

Harry Hoster, Lancaster University

8th October 2015

The real lesson of Volkswagen's 'dieselgate' scandal is that we must ditch petroleum fuels, writes Harry Hoster. There's new, clean technologies just waiting to take off - and the most promising is fuel cells. They will also fit right into the new world of renewables, with surplus power from wind and solar making the hydrogen they burn. more...

UK's energy revolution - DECC's role usurped by new Infrastructure Commission

Oliver Tickell

7th October 2015

This week George Osborne took the entire energy policy brief out of the department for energy and climate change, and handed it to the new National Infrastructure Commission. It could mean a swift end to the Hinkley C nuclear plant and a new wave of renewables - but don't count on it. NIC chairman Lord Adonis is no green dreamer. But at least he takes energy seriously. more...

Hinkley C's claimed benefits evaporate under scrutiny

Paul Dorfman

6th October 2015

To explain their desperation to commit an estimated £76 billion of public money to the Hinkley C nuclear project, writes Paul Dorfman, the Treasury and its Chancellor, George Osborne, claim there are other benefits that justify this vast expenditure. So what exactly are they? And do the claims survive critical examination? more...
