Texas legislature has adopted the Texas Renewable Energy Industries Association’s definition of renewable energy, which is:
“Any energy resource that is naturally regenerated over a short time scale and derived directly from the sun (such as thermal, photochemical, and photoelectric), indirectly from the sun (such as wind, hydropower, and photosynthetic energy stored in biomass), or from other natural movements and mechanisms of the environment (such as geothermal and tidal energy). Renewable energy does not include energy resources derived from fossil fuels, waste products from fossil sources, or waste products from inorganic sources.“
The United States currently relies heavily on fossils fuels (nonrenewable) that are drawing on finite resources, are becoming too expensive and that can be (are) environmentally damaging to retrieve.
It contrast, renewable energy is derived from natural processes that are replenished constantly. In addition, renewable energy resources and significant opportunities for energy efficiency exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency, and technological diversification of energy sources, would result in significant energy security and economic benefits.
