Biomass for energy is the common sense option

Matthew Rivers

5th June 2015

Today UK campaigners against burning biomass for power will deliver a 110,000 signature petition to DECC to protest at government subsidies for the practice. But in this 'Right of Reply' article Matthew Rivers, chairman of Drax Biomass, argues that biomass combustion is sustainable, benign, and helps to conserve forests worldwide. more...

'Global Apollo' programme for renewables cannot take off without political power

James Dyke

4th June 2015

The Apollo Programme proposed this week to make renewable energy cheaper than coal through technological advances is welcome, writes James Dyke. But the real problems are political, not technological. Unless we back the Apollo vision by challenging the power of fossil fuel companies, it can never succeed. more...

False promise of 'carbon capture' exposed

The Ecologist

26th May 2015

The widely touted 'carbon capture and storage' technology is much more expensive than wind and solar, says a Greenpeace report. It also represents a perverse subsidy to the fossil fuel sector that will only boost coal and oil, and delay the transition to a renewable energy system. more...

Lies, damned lies, and energy statistics - why nuclear is so much less than it claims to be

Neil Crumpton

26th May 2015

It's odd how often the contribution of nuclear energy is overstated, writes Neil Crumpton, by mixing up 'energy' and 'electricity', while a similar trick to understates the importance of renewables like wind and solar. Even odder is how the mistake always seems to go the same way, to make nuclear look bigger than it really is, and renewables smaller. Welcome to the nuclear 'X factor'! more...

Power struggle: after Germany's renewables surge, can it keep its coal in the ground?

Melanie Mattauch

22nd May 2015

Germany's 'Energiewende' has made the country a global renewable energy powerhouse. So why have its carbon emissions gone up? Not because of nuclear closures, writes Melanie Mattauch, but because powerful fossil fuel companies have blocked effective climate action. Now the fight is on as public calls to keep the coal in the ground get too loud to ignore. more...

Accidents, waste and weapons: nuclear power isn't worth the risks

Mark Diesendorf

19th May 2015

Nuclear advocates must be admired for their optimism if nothing else, writes Mark Diesendorf. Disregarding over half a century of evidence that nuclear power is dangerous, expensive, enables the spread of nuclear weapons, and produces wastes we still don't know what to do with, still they cling to the 1950's dream of 'electricity to cheap to meter'. more...
Despite constant reports of China's soaring coal burn, the country's carbon emissions are falling. Photo: coal power plant near one of Beijing's 'Ring Roads' by Bret Arnett via Flickr (CC BY-NC-SA).

Is China's emissions slump real - or are they making it up?

David Toke

17th May 2015

Cynical western media are pouring cold water on reports of China's declining carbon emissions, writes David Toke. The trouble is, the cross-sectoral statistics that demonstrate the reductions are actually rather convincing. Maybe journalists should be asking different questions - like just how well is the US performing? more...

Coal-heavy utilities stand in the way of a green internet

The Ecologist

12th May 2015

Powered by 100% renewable energy, Apple is maintaining its lead as the internet's greenest company, But others are lagging behind: Google has yet to reach 50% and relies heavily on coal, while Amazon's AWS, the massive 'dark cloud' of the web, won't even answer questions. more...

Renewable energy alone cannot reverse global warming or make a sustainable world

Pete Dolack

25th May 2015

The renewable power boom is excellent news for people and planet, writes Pete Dolack. But let's not get carried away: much energy that claims to be 'renewable; like biomass and big hydro, is no such thing. And greening our energy is just one of many steps to a sustainable world. The greatest challenges - like tackling the monster of infinite 'growth' - all lie ahead. more...

Saudi Arabia's oil price manipulation - let's get rich while we still can!

Karl Grossman

2nd May 2015

The oil industry and oil producers have a long history of market manipulation, writes Karl Grossman, and we see it going on right now with the low oil price that's squeezing fracking and getting America back onto gas-guzzling SUV's. But longer term, solar power is going to win out, and even Saudi Arabia knows it. Its game? To make out big, while the going's good. 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...

Energy market madness is the death spasm of the oil age - renewables now!

Nafeez Ahmed

4th February 2015

Current oil price volatility is a symptom of the end of cheap oil, writes Nafeez Ahmed, and it's destablising the entire global economy. The answer is a major shift to renewables - but the the International Energy Agency, which should be leading the transition, is in the grip of nuclear and fossil fuel interests. Instead the leadership must come from us, the people! more...

WEF: Big energy CEOs don't get the renewable revolution

Chris Goodall

23rd January 2015

Launched at Davos this week, a WEF report on electricity generation predicts that solar power will cost twice as much in 2030, as the lowest cost sources today, writes Chris Goodall. It's sources? WEF isn't telling. But if 'facts' like these are driving the decisions of big energy CEOs, heaven help their companies in years to come. more...
