The renewable energy business is booming. Here is a survey of the leading renewable technologies of today and tomorrow -- wind, solar, biomass and hydrogen.
Enthusiastically, politics and business embraced so–called biofuels promising energy independence and carbon neutrality. But while fuel is getting green, land for food is getting scarce.
