Disasters fueled by global warming are the "new normal." Figuring out how to avoid the next one must be a top priority for all of us.
From algae to alloys, ingenuity in the world’s laboratories is fueling experiments to find new ways of providing viable sources of clean energy.
By adapting a tropical grass to grow in the British climate, scientists hope to be able to replace coal in power stations with biofuel.
Scientists say meeting the tougher demands of many countries on limiting global temperature rise may be technically feasible, but would risk worsening world hunger.
Global energy has gotten a climate-friendly boost as scientists say solar power alone could now meet the needs of California five times over.
Germany cut emissions and boosted renewables last year, but critics say CO2 reduction targets can’t be met unless it closes coal-burning power stations.
A report published ahead of Tuesday's U.N. Climate Summit illustrates that poor and prosperous nations, tiny islands and great cities, can satisfy all their energy needs from renewables.
Producing biofuel from plants can help to reduce fossil fuel use and climate change emissions, but scientists warn of risks that some species may become unwelcome and damaging invaders.
A scientific report for the U.N. Climate Summit sends out a positive message that the tough task of cutting CO2 emissions to limit global temperature rise to below 2°C can be achieved by following a set of bold practical steps.
Scientists in the U.S. have found new ways to make biofuel, increase crop yields and exploit carbon dioxide through novel applications of familiar materials.
