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...

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...

Solar heat - transforming rural enterprises around the tropics

Anne Wheldon

4th June 2015

Solar energy is not just about electricity, writes Anne Wheldon. It's also about heat - and three innovative projects highlighted by the Ashden Awards are showing how solar heat can dramatically reduce the carbon footprint of food processing and farming, while helping agricultural businesses increase profits. 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...

Mayday, Mayday - Tesla's battery just killed fossil and nuclear power

Oliver Tickell

1st May 2015

Tesla Energy's new mains power battery has just transformed the energy market - giving a huge boost to small scale renewable energy and killing off both fossil fuelled and nuclear power in the process. 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...

Beginning to see the light ... shining the sun's rays into Cairo's dark streets

Patrick Keddie

4th February 2015

Egyptian researchers have come up with a solution to the a lack of sunlight in Cairo's narrow and dingy streets, writes Patrick Keddie: a sine-wave panel that reflects light as soon as the sun rises. Initial tests indicate a potential five-fold increase in light levels. more...

Here comes the sun: explosion in solar power beckons

Ralph Gottschalg

12th December 2014

Solar power has a sunny future - even without any major breakthroughs, writes Ralph Gottschalg. There are huge gains to be made simply by getting smarter and using existing technologies more effectively. A new report shows that - given political support - solar PV could be competitive in the UK by 2020. more...

Walmart, Asda owners using their billions to attack rooftop solar

Mike Gaworecki / DeSmogBlog

20th November 2014

The Walton family, owners of Walmart and Asda, project a 'public environmentalism', writes Mike Gaworecki. But their real agenda is to advance a monopolistic corporate economic model that is threatened by decentralised energy solutions like rooftop solar. The answer? Exterminate! more...

Seven breakthrough solar technologies - but will they work?

Zachary Davies Boren / Greenpeace Energy Desk

17th December 2014

A bunch of innovations are taking place in the world of solar power, writes Zachary Davies Boren - and one or more of them could just propel the technology from providing just 1% of the world's electricity, to dominating the world's energy supply. Provided they work ... more...

Solar power is getting cheaper quicker than the IPCC thought

Helle Abelvik-Lawson

4th November 2014

The cost estimates for solar PV used by the IPCC in its latest report fail to take into account recent price falls for the technology, reports Helle Abelvik-Lawson, and exaggerate financing costs. The result is to understate the importance of PV in a low carbon future. more...

IEA: Solar could be world's biggest power source by 2050

Mike G / DeSmogBlog

10th October 2014

Solar power could be producing over a quarter of the world's electricity within 35 years, according to the International Energy Agency. But in the US, Congress's failure to extend solar tax credits is causing projects to be withdrawn.
