In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine.

Concentrating solar power plants produce electric power by converting the sun's energy into high-temperature heat using various mirror configurations.

Biomass is plant matter such as trees, grasses, agricultural crops, and other living plant material. Biomass can be used in its solid form for heating applications or electricity generation, or it can be converted into liquid or gaseous fuels.

Biofuels are liquid transportation fuels made from plant matter instead of petroleum.

Hydropower is the kinetic energy of flowing water, which when captured can be used to power machinery or converted to electricity

Photovoltaic (or PV) cells are devices that use semiconductor materials—similar to those used in computer chips—to convert sunlight directly into electricity. The electric current can either be used immediately, or it may be stored, as in a battery, for later use.

Solar thermal technologies use the non-polluting power of the sun to heat water and air in commercial and residential buildings.
