As a country, we have demanded more and more energy. But we have not brought on line supplies needed to meet that demand...We can explore for energy, we can produce energy and use it, and we can do so with a decent regard for the natural environment.
Energy is ability so do work. Energy comes from different sources such as oil, cola, wind, the sun, water, natural gas. Renewable energy is a source of energy that can never be exhausted. We can obtain renewable energy from the sun(solar energy), from the water(hydropower), from the wind(windmills), from hot dry rocks, magma, hot water springs(geothermal) and even from firewood, crop residues and waste(biomass).
