Europe Retreats From Biofuels
A committee in the European Parliament endorsed a plan that calls for 10% of transportation fuels to come from sources such as plants and grains by 2020, but it also calls for a switch to other renewable sources over time.
Ontario Plugs into Cow-Power
Later this summer residents in the Province of Ontario will be able to plug in their homes to a new source of electrical power: biogas derived from cow manure.
Sweden Creates Sewage-Powered Cars, But Auto Industry Lags Behind
Household sewage is currently fueling cars in Sweden, and has for years. But Swedish industry has given up on the idea, investing in ethanol-based gasoline.
Landfill Gas To Fuel Garbage Trucks
