Solar4Scholars: What Is Renewable Energy?
Renewable energy is becoming more popular. For example, the state of Iowa has over 600 wind turbines that help supply its power. California has the three largest wind farms in the world. Wisconsin, Minnesota and New Hampshire have large wind farms currently in use or in being planned. California has a plan for "a million solar roofs" by 2018.
Renewable and non-renewable
Renewable energy is energy that is easily replaced or supplied by a nearly infinite source, such as the sun or the wind. Some examples are solar, wind, hydro and geothermal. Many of these forms of usable energy will be available as long as we have the earth and the sun.
Non-renewable energy is any form of energy that cannot be recreated in a short amount of time. Non-renewable energy is energy that has a limited supply that will likely run out in your lifetime. Examples of non-renewable energies are coal, oil and gas.
We can make a rough but interesting generalization that renewable energies are harder to store than non-renewable energies. This is one reason why non-renewable energies are considered more useful. However, non-renewable energy is making headway in this area.
Many people today are concerned about saving energy. Saving (conserving) energy is a practical way to keep our individual energy costs down and also the costs to our society.
Renewable energy comes in several different forms.
Solar thermal makes use of solar energy to heat household water or swimming pools. You can read more about solar thermal.
You can also encourage your family to heat with solar. Read about solar thermal energy.
Geothermal energy is heat from the earth. Learn more about geothermal energy.
This increasingly popular form of energy is actually found anywhere. We encourage you to encourage your family to learn more about geothermal energy.
