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.

Geyser eruption caused by geothermic energy
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.
