Carbon-free by 2050?feedproxy.google.com | 24 Apr 2012
Replacing carbon fuels with renewable energy sources is clearly a necessary goal for a sustainable future. A recently released report by the Intergovernmental ...
Aircraft of the future could capture and re-use some of their own powerScienceDaily.com | 23 Feb 2012
Tomorrow's aircraft could contribute to their power needs by harnessing energy from the wheel rotation of their landing gear to generate electricity. They could use this to power their taxiing to and from airport buildings, reducing the need to use their jet engines. This would save on aviation fuel, cut emissions and reduce noise pollution at airports.
Carbon mitigation strategy uses wood for buildings first, bioenergy secondScienceDaily.com | 22 Nov 2011
A new study is first to focus on the extra carbon savings that can be squeezed from trees when wood not suitable for long-term building materials is used for bioenergy: Depending on the process used, ethanol from woody biomass emits less greenhouse gas than an equivalent amount of gasoline, between 70 percent and a little over 100 percent less. In contrast, corn ethanol reduces greenhouse gas emissions 22 percent on average.
Large differences in the climate impact of biofuels, Swedish research findsScienceDaily.com | 15 Nov 2011
When biomass is combusted the carbon that once was bound in the growing tree is released into the atmosphere. For this reason, bioenergy is often considered carbon dioxide neutral. Research from Sweden, however, shows that this is a simplification. The use of bioenergy may affect ecosystem carbon stocks, and it can take anything from 2 to 100 years for different biofuels to achieve carbon dioxide neutrality.
Senate rejects measure to stop EPA on climateReuters | 06 Apr 2011
The U.S. Senate rejected a measure on Wednesday to kill the Environmental Protection Agency's regulation of greenhouse gas emissions, handing President Barack Obama a victory in his effort to quicken the move to clean energy.
Government's own solar project scrappedGuardian Unlimited | 06 Apr 2011
The government has cancelled its own flagship solar energy project because the Department of Energy and Climate Change's (DECC) proposed cuts to solar feed-in tariff incentives will make the scheme unviable. That is the charge from "stakeholders" who contributed to a Whitehall project to assess the...
Japan has no immediate plan to review 2020 climateReuters | 01 Apr 2011
Japan has no immediate plan to review its emission reduction pledge for 2020, the environment minister said on Friday, in the first official comment about the target after a nuclear crisis has boosted the country's need for power from fossil fuels.
Spain's financial crisis claims another victim: the solar power industryGuardian Unlimited | 30 Mar 2011
The Spanish government has slashed its solar power subsidies Spain had one of the world's most ambitious - and generous – plans to boost the amount of electricity it generates from the sun. That dream, for the solar industry at least, has turned sour. Just days before Christmas, the government slashed the level of subsidies that all new and existing photovoltaic (pv) solar projects will receive.
U.S. drops to 3rd in clean-energy investment: PewReuters | 29 Mar 2011
The United States fell one spot to third place in clean-energy investment last year as the lack of a national energy policy hurt purchases in wind and solar power and other technologies, a report said on Tuesday.
Scottish tidal power station gets approvalGuardian Unlimited | 17 Mar 2011
Underwater power station to generate enough energy for 10,000 Hebridean homes, and some distilleries. The world's first major tidal power station is to be installed in a deep, but sheltered, channel between two Scottish islands, providing electricity for up to 10,000 homes.The array of 10 underwater turbines will be placed between the inner Hebridean islands of Islay and Jura, both well known for their malt whisky.
Letters: Nuclear risks and the renewable alternativesGuardian Unlimited | 16 Mar 2011
The assessment in your editorial (15 March) that "the balance of the rational argument could conceivably be more in favour of nuclear [power] in a month's time" is not just premature but ignores a number of important factors. Most worryingly, terrorists will have seen the devastation, disruption...
UK energy use fell by 5% in eight yearsGuardian Unlimited | 06 Mar 2011
France's consumption rose by 7% - and in Europe only Denmark and Ireland used less energy per unit of GDP than UK. The UK is one of the top performers in Europe on energy efficiency, according to a European Commission report. Energy use fell by more than 5% from 2000 to 2008 in the UK – the only major European economy to see a drop. Germany's consumption held level, while France's rose 7%. Overall, energy use in the 27 EU countries increased by more than 4%.
Biofuel boom could follow oil price spikeGuardian Unlimited | 01 Mar 2011
When biofuels match oil on price, production could boom in the developing countries that also have the greatest need to boost food supply. The production of biofuels, good thing or not, will be decided by the setting of targets in the big western energy markets, right?
