Time to tap in to an underused energy source: wasted heat

Rob Raine

10th September 2015

The single biggest energy service we all need is heat, writes Rob Raine - yet it's largely ignored in the energy policy discourse. By focusing on heat as well as power, we can accelerate the transition to renewable energy sources and - because heat stores are far cheaper than batteries - keep the costs down. more...

Do the UK government's sums on Hinkley and climate change add up?

Doug Parr / Greenpeace Energydesk

20th August 2015

It's a fair question, writes Doug Parr, but one to which we are getting no answers - the government is keeping its sums and energy models secret. It looks as if the energy department, DECC, is making things up as it goes along to justify its pro-nuclear, anti-efficiency and anti-renewables policies. And when it all goes disastrously wrong, who will end up paying for the mess? We will. more...

China's solar industry hits downturn

Kieran Cooke

16th August 2015

China is by far the world's biggest producer of solar panels, writes Kieran Cooke. But the industry is suffering from over-capacity, razor thin profits and a failure to innovate. more...

For Labour to win, green must be the new red

Keith Barnham

13th August 2015

The success of the SNP and surveys carried out by DECC show that green energy is overwhelmingly popular, writes Keith Barnham. Labour's failure to support renewables and oppose nuclear power and fracking may have cost them the last election - but now, with the rise of Jeremy Corbyn there's a real chance for the party to put that right. more...

Revolutionary 'sea fence' promises tidal power price crash

Alex Kirby & Oliver Tickell

11th August 2015

An new design of tidal power turbines will generate power at a third the price of current technologies, write Alex Kirby & Oliver Tickell, even at a lower price than offshore wind - without endangering marine life. more...

Wind farm subsidies bad, farm subsidies good?

Brendan Montague /

10th August 2013

Major funders of the pro-fossil fuel Global Warming Policy Foundation are always keen to speak out against public support for renewable energy, writes Brendan Montague. So how come they're so keen to help themselves to a fortune in farm subsidies? more...

Jeremy Corbyn: the green Britain I want to build

Jeremy Corbyn MP

7th August 2015

We need a renewable energy revolution, an end to fracking, no new nuclear power, efficient homes, and the break up of our energy cartels, writes Jeremy Corbyn, All that, and strong protection for wildlife and oceans, no TTIP trade deal with the US, clean air to breathe, and massive investment in public transport. Is there anything not to like? more...

Jeremy Corbyn: Big Six under public control, a solar panel on every roof and no new nukes

Damian Kahya / Greenpeace Energydesk

24th August 2015

Despite Labour's 'great purge' of left-leaning voters in the leadership election, Jeremy Corbyn remains the odds-on bookies favourite. So if he comes to power, what policies can we expect in energy and climate change? Damian Kahya asks the questions ... and is astounded at the range and scope of his ambitions. But how much could he really deliver? more...

New solar tech slashes energy payback time to a few months

The Ecologist

5th August 2015

Solar panels made using perovskite technology pay back the energy used to make them ten times faster than those using silicon. In time, this could lead to similar falls in price. more...

Energy: the future is renewable and distributed

Chris Wright

24th August 2015

With centralised fossil-fuel and nuclear generation both undesirable and increasingly unviable, the answer is to make our energy local, distributed and renewable, writes Chris Wright. But to complete the picture we need battery systems for backup, stability and efficiency. And one could be coming your way soon ... more...

Fighting back for the green economy

Alasdair Cameron / Friends of the Earth

31st July 2015

The UK government has timed its attacks on renewable energy to perfection, writes Alasdair Cameron. Public 'consultations' on proposals to cut away support for wind and solar are running over the holidays - and many of those affected don't even know about it. It's time for us all to stand up for the green economy and make our voices heard! more...

The $7 trillion solar tsunami in our midst

Assaad W Razzouk

31st July 2015

Never mind government inaction (or worse) on climate change, writes Assaad W Razzouk. Solar power costs just keep on falling, and it's already providing the lowest cost electricity across much of the world. With $7 trillion of investment piling into the sector, the momentum is now unstoppable. more...

Norway's 'green battery' hydro plan for Europe

Paul Brown

27th July 2015

Engineers in Norway aim to put their mighty hydroelectric dams to a new purpose, writes Paul Brown - as giant batteries to store up surplus power from wind and sun across Europe, and put it back in the grid when generation falls off or demand is strong. more...

Who owns the wind?

Adam Ramsay

29th July 2015

The wind is a force of nature over which only someone with extraordinary delusions of grandeur can truly claim ownership, writes Adam Ramsay. But to prevent that, we must assert our belief that wind, sun and other drivers of our renewable future are a common heritage for us all to benefit from. more...

Buy Conservative! No other party washes greener

Oliver Tickell

24th July 2015

Are you suffering from cognitive dissonance? You should be, writes Oliver Tickell. After the most ferocious attack a UK government has ever mounted on the environment, David Cameron just claimed that his is the 'greenest government ever', as Amber Rudd proclaims her commitment to climate action. What's going on? more...

Tories' attack on green energy threatens climate and prosperity

Noam Bergman, Lee Stapleton & Mari Martiskainen

5th August 2015

With the US, China, Germany and other countries firmly fixing their aim on a low carbon, renewable energy future, the UK government has chosen precisely the opposite track, write Noam Bergman, Lee Stapleton & Mari Martiskainen. Its mission to destroy wind and solar power, undercut energy efficiency and boost nuclear power and fracking threatens serious, lasting damage. more...

Renewable energy sacrificed on the altar of corporate profit

Oliver Tickell

22nd July 2015

Perplexed by today's sharp cuts in solar power and other attacks on renewable energy in the UK? Don't be, writes Oliver Tickell. Really, it all makes perfect sense. You just have to understand their real purpose: to keep your energy bills high, along with power company profits. And never mind the 'green crap'! more...

Government turns fire on solar power

Kyla Mandel /

20th July 2015

Energy secretary Amber Rudd promised 'a new solar revolution' for the UK, writes Kyla Mandel. But now the industry is braced for a massive round of cuts that could kill off the sector, just as it's on course to be the UK's first subsidy-free renewable power source in 2020. more...

David Cameron is losing the plot on climate change

Doug Parr / Greenpeace EnergyDesk

16th July 2015

David Cameron is gunning for a strong climate agreement in Paris this December, writes Dr Doug Parr. Meanwhile his government is doing all it can to undermine renewable energy and energy efficiency in the UK, and lock us into a high carbon, fossil-fuelled future. Can he really have it both ways? more...

Whatever happened to the 'greenest ever' Conservative Party?

Steffen Böhm

11th July 2015

Just when the UK's government might want to be boosting its green credentials it has chosen to do the precise opposite, writes Steffen Böhm: giving tax breaks and subsidies to oil and gas, while attacking renewables and energy efficiency. We must unite to oppose these destructive and short-sighted policies more...

Osborne's £3.9bn stealth attack on renewables

Oliver Tickell

9th July 2015

The UK government kicked away one of the main financial supports for renewable energy in yesterday's budget. The surprise move will cost the sector £3.9 billion over the next five years and undermines any prospect of the country meeting its EU renewable energy targets. more...
