Geothermal Energy

One type of alternative energy is geothermal energy. Geothermal energy is heat energy that comes from within the earth. The earths core continuously generates temperatures hotter than the suns surface. Many geothermal reservoirs are deep underground but can sometimes find their way to the surface through volcanos, hot springs and geysers. The most active geothermal resources are found along the Ring of Fire, which borders the Pacific Coast. Many of the geothermal reservoirs in the United Stated are located in California, Alaska and Hawaii. These states, which border the Pacific Ocean are located in the Ring of Fire. When magma approaches the surface of the earth it heats ground water creating hydrothermal resources. Naturally occurring areas of hydrothermal resources are called geothermal reservoirs. In order to confirm that a geothermal reservoir exists it is necessary to drill a well and test the temperature underground. It is possible to tap into this heat energy by digging deep wells and pumping heated underground water to the surface. This energy can be used to generate electricity and heat buildings and homes. Because heat is continuously produced in the earths core and the water cycle replenishes water to be heated, geothermal energy is considered a renewable resource. Geothermal energy is a great option for an alternative home energy source and is a safe, cheap source of energy.

There are three main use of geothermal energy, one is the direct use district heating system, which uses hot water from geothermal reservoirs near the surface to produce heat. Geothermal energy can also be used for electricity generation from a geothermal power plant. Power plants are usually built near a geothermal reservoir located within a mile or two of the earths surface. Geothermal power plants release one to three percent of the carbon dioxide emissions as a fossil fuel plant and emit 97 percent less acid rain. The third use of geothermal energy is geothermal heat pumps. These pumps use stable ground water temperatures near the surface to regulate temperatures above ground. According to the EPA, geothermal heat pumps are the most energy efficient alternative energy heating source. They are the most environmentally friendly, energy efficient and cost effective alternative energy system due to the fact that they have almost no negative impact on the environment. When water from a geothermal reservoir has been used it is injected back into the earth to be recycled.

The McCoy power report is an alternative energy related company that provides data about every electrical power plant using an alternative energy resource. This data is collected worldwide and can be very useful in determining which type of alternative energy is best for each individual consumer. Another helpful source for information on renewable resources is to hire an alternative energy consult. These developers specialize in finding alternative energy sources and can be very helpful in implementing alternative energy projects.
