Energy, Renewable and Nonrenewable Forms
By Brenda B. Covert
  

1     Energy is power - usable power. It is the ability to do work. It comes in many different forms, such as electrical, sound, light, chemical, heat (thermal), mechanical, and nuclear energy.
 
2     All forms of energy come from somewhere. We call those places "sources." For example, the sun is a source for light energy as well as solar energy, which is the changing of sunlight into electricity through the use of solar panels. These sources can be sorted into two groups. The first is renewable (a type of energy that can be used over and over, like the sun). The second is nonrenewable (an energy source that can be used up and is unable to renew - or create more of itself - in a short amount of time).
 
3     Renewable energy sources include the sun, wind, water, heat from within the Earth (called geothermal energy), and plant (biomass) waste products. These renewable sources are all natural-occurring elements. Human beings have found ways to use these energy sources. Besides harnessing the sun's solar energy, we use wind to power windmills, turbines to create hydroelectric energy with water, geothermal energy (heat from within the Earth) for use in power plants. Power plants are not strong bushes or weeds; a power plant is a large building where power is produced.
