Simply put, renewable energy is the energy we use that comes from natural resources. These resources are replenished naturally making them ideal for energy consumption considering the massive amounts of energy consumed on a daily basis.
Biomass: Biomass energy is completely organic, produced from natural materials like wood, animal manure and even garbage. More trees and plants can always be grown so this is a good source of reliable energy. An example would be when we burn wood in a fireplace, the burned wood releases heat that warms our homes.
Hydropower: Hydropower energy production is very popular and has been around for some time. The swifter the water moves the more energy it produces. A primitive example would be the old water mills that were used to ground grain in grain mills.
Geothermal: Geothermal energy is generated in the core of the Earth. Rocks go through constant radioactive decay so the energy supply is endless. People have figured out how to harvest this great source of energy by digging wells in to the deep pockets of heated water in the Earth's crust and then using this water to heat their homes.
Wind: Wind energy is captured usually by using wind mills. It is renewable because there is always wind as long as their is the sun. It is a natural part of the Earth's weather patterns. When the wind blows it turns the blade of the wind mills, this in turn results in the production of electricity when the turbines connected to the blades begin to move.
The few examples of renewable energy sources listed here are not the only ways we are able to gather renewable energy. In fact, scientists are working every day to discover new sources and ways we can harvest those sources. The possibilities are almost endless!
