Matched hybrid systems may hold key to wider use of renewable energy

The use of renewable energy in the United States could take a significant leap forward with improved storage technologies or more efforts to 'match' different forms of alternative energy systems that provide an overall more steady flow of electricity, researchers say in a new report.

Clean energy 'bio batteries' a step closer

A report published today shows how electrons hop across otherwise electrically insulating areas of bacterial proteins, and that the rate of electrical transfer is dependent on the orientation and proximity of electrically conductive 'stepping stones'.

Limiting short-lived pollutants cannot buy time on CO2 mitigation

Reducing emissions of non-CO2 gases and air pollutants with climate effects would bring health benefits and near-term climate co-benefits - but the impact on long-term climate change might be lower than previously estimated, according to a new study of the potential of air pollution and carbon dioxide mitigation in climate stabilization scenarios.
