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...

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...

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...

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...

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...

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...

Senseless and damaging: UK's solar cuts

The Ecologist

22nd July 2015

The UK government has announced massive cuts in support for solar roofs and farms that appear designed to undermine investor confidence just as the technology is on track to be subsidy-free by 2020. more...

Greece’s anti-solar, coal-based energy policies underlie its economic collapse

Takis Grigoriou / Greenpeace EnergyDesk

3rd July 2015

As Greece prepares for its referendum, Takis Grigoriou takes Greece to task for its highly polluting lignite power sector, its ditching of a successful solar program in favour of more coal, the minimal insulation in its buildings that locks in high fuel bills, and Syriza's failure to tackle these issues. The good news? Greece's latest €1.4bn coal project looks like going unfunded. more...

NASA's warning - SpaceX crash highlights dangers of nuclear power in space

Karl Grossman

2nd July 2015

Sunday's SpaceX crash sends a powerful warning of the dangers of nuclear power on spacecraft, writes Karl Grossman. But will NASA listen? Despite the success of solar-powered missions, it's planning to use plutonium to power future missions and a new report asserts a continuing need for the technology - even as Russia ditches the idea. more...

43%! New record for UK renewable power

Chris Goodall

8th June 2015

Thanks to the windy, sunny weather conditions on Saturday, the UK's output of renewable power reached an all-time record level of 43%, writes Chris Goodall. At the same time power from coal reached a low of just 7%, it what may be a record low contribution. more...

American revolution: cities seize control of essential local services

Max Holleran

9th May 2015

Fed up with being gouged by profit-driven corporations, let down by state neglect and under-investment, urban communities across the US are taking control of local services like public transport, energy, water, internet and telecoms, writes Max Holleran - bringing better service, lower prices and clean energy. more...

The mirage of fossil fuel wealth - our energy future is green, renewable, decentralised

Vicente López-Ibor Mayor

20th April 2015

Hopes of strengthening Britain’s energy security are often pinned on the fossil fuel industry says Vicente López-Ibor Mayor, as exemplified by the hysteria over the claimed 'discovery' of 100 billion barrels of oil beneath Gatwick airport. But the real long-term solution lies with abundant and ever cheaper decentralised renewables. more...

Investors pile in as renewables rise to record level

Tim Radford & Oliver Tickell

16th April 2015

The world's smart money is piling into renewable energy, solar power in particular, write Tim Radford & Oliver Tickell, as renewables pull away from fossil fuels in terms of both investment and new generation capacity added each year. more...

Deepening drought forces Brazil to embrace solar power

Jan Rocha

6th April 2015

Without water to feed its hydroelectric dams, drought-hit Brazil is turning to solar power - dubbed 'a fantasy' by the country's president just a few years ago, writes Jan Rocha. Now thousands of megawatts of floating solar panel 'islands' are to be installed on dam reservoirs. more...

After UK's record solar year, government tries to kill the sector

Oliver Tickell

3rd March 2015

The UK will soon complete a record year for solar installations, almost doubling the nation's solar capacity. But drastic and overtly discriminatory changes to support for renewables may see solar installations collapse to 1% of current levels. more...

Forget nuclear - Saharan sunshine for UK baseload power!

Chris Goodall

25th February 2015

As the UK's nuclear dream fades, writes Chris Goodall, investors are turning to the possibilities of 'Concentrating Solar Power' in the Sahara connected to Europe by HVDC power lines. The cost would be much lower than nuclear or offshore wind, and provide reliable baseload capacity. With the UK government's say so, Tunisian sunshine could soon be powering our grid. more...

Renewables to transform India's energy landscape in seven years

Areeba Hamid / Greenpeace EnergyDesk & Oliver Tickell

31st February 2015

India's renewable power capacity is set to reach 170GW by 2022, write Areeba Hamid & Oliver Tickell - reducing power shortages and bringing electricity to off-grid of rural communities for the first time. But it may also have an unintended consequence - cutting off investment in India's troubled coal sector as prospects for future profitability evaporate.. more...
