Reducing water consumption at solar thermal plants raises costs and decreases power production.
A proposed pipeline from Canada won't increase greenhouse gas emssions.
Startup Global Bioenergies uses genetic engineering to avoid one of the costliest steps in biofuel production.
New approach developed at MIT could generate power from sunlight efficiently and on demand.
A low-power, multiroom sensor network watches for drips and runs on a coin-cell battery.
Aquion has started production of a low-cost sodium-ion battery aimed at making renewable energy viable.
