Whether what propels a car is electricity, liquid fuels, natural gas, or hydrogen, the critical impacts all occur far from the car itself at locations where fuels originate and natural resources are exploited.
Algae cells make fat quickly, a finding that means they could hold promise as a sustainable, environmentally sound source of oil.
The pro-renewables group E2 forecasts growth in advanced biofuels – but probably not fast enough to meet the mandates in the U.S. renewable fuel standard.
A new study finds that genetically modifying plants could help reduce the costs of biofuel production.
The EPA sets its final 2013 Renewable Fuel Standard target for cellulosic biofuels use, and it is far less than what has previously been talked about.
Focusing on fast-growing and hardy microscopic algae, rather than the most oil-rich, could lead to cheaper and more efficient alternative fuel.
Using waste cooking oil as a starting material reduces production costs while still producing medical-grade bioplastic.
