Solar and Wind Power

With environmental concerns as they are today, renewable energy is enjoying a time of heightened interest. Renewable energy can come from a number of sources such as wind, water, sunlight and heat from geothermal sources. Today, approximately 20% of the energy in the world comes from renewable sources. While most of this comes from burning wood a very large amount also comes from hydroelectricity.

Renewable energy comes from natural resources, as opposed to non renewable energy which comes from resources that will one day run out. The advantage of natural resources, is that they are typically cleaner to run, making less of an impact on the environment and we do not need to worry about the running out. Renewable energy typically comes from water, wind, the sun and the earth’s natural heat, or geothermal energy.
