Unorthodox methods for power generation, such as wind, hydroelectric, and geothermal, account for less than one percent of the world's total power generation, but they can play an important regional role, as determined by economics and availability. Through chemistry, solar panels for both thermal and photovoltaic generation, lightweight carbon fiber propellers for wind generation, concrete and metal turbines for hydroelectric plants, and corrosion-resistant materials for harnessing geothermal sources have all been developed.

The power consumption of energy-saving bulbs may be up to 80% less than that of the incandescent ones.The creation of high capacity solar cells producing heat and energy, of carbon-fiber strenghtened wind turbines utilizing wind power, of special cements and metal turbines used in hydroelectric facilities, and of a variety of non-oxidizing materials used at geothermic springs is due to a wide range of chemical reserach and development.
The amount of solar energy reaching the surface of the Earth in one and a half days is about the amount of energy that could be obtained from all of the Earth's non-renewable resources of oil. The Sun's one-hour solar-energy production would be sufficient to supply all of the mankind's energy needs for one entire year, provided we were able to use it ompletely.
