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...

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...

Pacific Islands heading for 100% renewable energy

Maxine Newlands

28th May 2015

A host of Pacific nations are turning to renewable technologies to satisfy 100% of their energy, writes Maxine Newlands. Samoa is aiming to achieve 100% renewable energy by 2017, while Tokelau has already reached 94% including 100% of its electricity. 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...

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...

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...
