Solar energy is affordable, inexhaustible and clean. The developement of it will have huge longer-term benefits.
Wind power is the conversion of windenergy into a useful form of energy, such as using: wind turbines to make electricity, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships.
Geothermal power is cost effective, reliable, sustainable, and environmentally friendly,but has historically been limited to areas near tectonic plate boundaries .
Bioenergy is renewable energy made available from materials derived from biological sources,the biological material used as a biofuel, as well as the social, economic, scientific and technical fields associated with using biological sources for energy.
Hydropower or water power is power derived from the energy of falling water, which may be harnessed for useful purposes.
Hydrogen fuel is a zero-emission fuel which uses electrochemical cells, or combustion in internal engines, to power vehicles and electric devices.
