The Types of Green Energy?

By Jerry Dyess

What comes to mind when you think of "green energy"? A huge piece of glass on the roof of your house? An old windmill with wires strung into the house? Green energy may bring to mind an energy option that seems crude and inefficient. When you look at the latest green energy technology, you find it takes a lot of money to pay a professional to install a system in your home. Green energy does not need to be expensive or new to be able to use it.

Green energy is any form of force that can be used repeatedly and never run out and does not harm the environment. Solar and wind energy is the most well known sources of green energy, but hydroelectric as well as geothermal are also sources of green energy. Take a closer look at the reasons these are green sources of energy.

Solar energy is still being developed; it is probably the most talked about form of green power. In the future, many believe we will be producing solar power with plastic wrap; the fact is they have developed a form of plastic wrap that will collect solar rays for producing power. Solar power is still not ready for widespread use and is considered too expensive and difficult to take care by the average person. In years to come solar power will prove to be a good option for alternative energy.

Wind power has actually been around for hundreds if not thousands of years. When people think of energy most of the time they are thinking of electricity, but any energy that makes things move or build up pressure is considered energy production or harvesting. Windmills were the first form of wind energy collection, and the modern equivalent are just as effective at producing electricity as their predecessors were at grinding flour. In fact, windmills are one of the least maintenance intensive source of energy, especially in what is known as the wind belt. The country's largest wind farm is located in Texas, utilizing miles, and miles of windmills to produce clean Texas energy.

Geothermal energy is a little more complicated. While places like Iceland and Wyoming have volcanic activity below their surface to provide steam and pressure, passive geothermal energy can actually be used on a worldwide level. How much energy do we use each year heating and cooling buildings? The temperature below the ground is a constant 65 degrees F and by tapping into that with thermal rods, we can keep our buildings at that same temperature, never having to heat or cool from a greater extreme than that.

Hydroelectric power may or may not be green depending on the circumstances. A small hydro plant is considered green, as it will not disturb the balance of nature, as they do not need to make changes to the water or the landscape to operate. A large plant on the other hand needs to create a large body of water by flooding an area in order to run the hydro plant. These are not considered green as they change the face of the land for years to come.

Many forms of green energy exist, but none of these was ever used for producing power. Green energy will help you be less dependent on conventional power companies. You are able to connect your green source of power to the grid and only use power from the electric company when you need it. This will help you do your part in keeping the earth a cleaner, greener place for our descendants.
