Algae-based biodiesel has been hyped in the past as a renewable fuel that can be produced here in the U.S., lowering greenhouse-gas emissions without displacing food crops or taxing water supplies. And yet it still hasn’t arrived in any significant way. There’s no single factor to blame for that, rather a combination of hurdles that no... Algae blooms could be a boon for eco-diesel under DOE-funded project
Algae-based biodiesel has been hyped in the past as a renewable fuel that can be produced here in the U.S., lowering greenhouse-gas emissions without displacing food crops or taxing water supplies.

But fleet buyers have embraced alternative... 
A new package of laws drafted by the European Commission aims to reduce consumption of fossil fuels within the European Union. Called "Clean Energy for All Europeans," the plan calls for emissions reductions in both the transportation and energy sectors, as well as increased use of renewable energy for electricity generation, and biodiesel for...
