Carbon-free by 2050?feedproxy.google.com | 24 Apr 2012Replacing carbon fuels with renewable energy sources is clearly a necessary goal for a sustainable future. A recently released report by the Intergovernmental ...
Carbon Storage | Renewable Energy Aircraft of the future could capture and re-use some of their own powerScienceDaily.com | 23 Feb 2012Tomorrow'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.
Renewable Energy Carbon mitigation strategy uses wood for buildings first, bioenergy secondScienceDaily.com | 22 Nov 2011A 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.
Renewable Energy Large differences in the climate impact of biofuels, Swedish research findsScienceDaily.com | 15 Nov 2011When 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.
Renewable Energy Scottish tidal power station gets approvalGuardian Unlimited | 17 Mar 2011Underwater 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.
United Kingdom | Energy Efficiency | Energy Production | Renewable Energy | Responses UK energy use fell by 5% in eight yearsGuardian Unlimited | 06 Mar 2011France'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%.
