Energy democracy: Lubicon Cree build a solar dream in a tar sands nightmare

Melina Laboucan-Massimo

15th November 2015

An 500-strong Indigenous community in Alberta, the heart of Canada's environmentally catastrophic tar sands industry, is fighting back against the pollution, writes Melina Laboucan-Massimo - by cutting themselves adrift from dependence on fossil fuels, and starting up their own solar power station: a vital first step towards building a just and sustainable society. more...

How the UK can get almost all its power from renewables - without new nuclear

Damian Kahya / Greenpeace Energydesk

21st September 2015

The government claims that we need nuclear 'baseload' power to keep the lights on, writes Damian Kahya. But a new study shows reliable, low carbon energy can be provided by combining diverse green technologies including efficiency, large scale renewables, 'smart grid', energy storage and rarely used fossil fuel backup. more...

Nuclear madness: £2 billion for Hinkley C. Why the Treasury must get its hands off energy

Oliver Tickell

21st September 2015

Today's announcement of a £2 billion government guarantee for Hinkley C confirms that Chancellor George Osborne and his Treasury cannot be trusted to run the UK's energy policy - which is precisely what they are doing. On top of decimating the renewables industry, now they're risking billions on a failed nuclear design owned by failing companies. It's time to stop the madness. more...

Fracking will only dig our fossil fuel addiction deeper

Oliver Tickell

16th September 2015

A new report on fracking and climate change from the Task Force on Shale gas presents a rosy picture of the fuel's role as a climate-friendly 'bridge' to a renewable energy future, writes Oliver Tickell. But the truth is the precise opposite - it's a climate disaster that will only delay the arrival of clean energy. more...

Floating turbines could harness the awesome power of the tides

Ross Jennings

18th September 2015

Tides in the UK's coastal waters could be generating 10GW of clean power, representing half of Europe's tidal resource, writes Ross Jennings. So far it's going unexploited, but a new generation of lightweight, low cast tidal turbines that float off the surface could soon get that electricity into our homes and businesses. more...

The solar age is upon us

Chris Goodall

1st September 2015

Solar PV costs have fallen by 75% over five years ago, writes Chris Goodall, making it the cheapest new power source for around half of the world's population. Now it's essential to keep incentives to drive demand for a few more years, and make it cheaper than fossil fuels everywhere. more...

Repowering renewables - a silver lining amid the gloom?

Oliver Tickell

28th August 2015

The Tories' decision to scrap the UK's renewable energy sector deserves condemnation, writes Oliver Tickell. But there is a silver lining: it creates the space in which to design better, cheaper, more cost effective support mechanisms to drive the clean energy revolution forward. more...

Government kills off UK solar industry

Oliver Tickell

27th August 2015

The UK government is to cut support for domestic rooftop solar to 13% of current levels, with similar cuts for bigger systems, and end all support for small scale renewables by 2019. The likely result, and surely the intention, is to kill off the UK's solar industry altogether. more...

'Plonkable' mirrors promise cheaper solar energy

Jeffrey Barbee / Guardian Environment

26th August 2015

The 'other' solar technology, CSP, which uses mirrors to concentrate the sun's rays, is about to get a lot cheaper, writes Jeffrey Barbee. A South African team has developed a low cost design suitable for mass production that can be 'plonked' on site straight from the factory. more...

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...

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...

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: 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...

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...
