Green energy refers to sources of energy that are non-polluting and environmentally friendly, and is also known as renewable energy or alternative energy. These are some of the most popular types of renewable energy.
Green technology is considered environmentally friendly because it reduces carbon emissions and pollution. Examples include biomass, geothermal power, wind power, hydroelectricity, and solar power.
Geothermal energy harnesses heat from the earth to provide a clean source of electricity. Since heat is constantly radiated from the earths molten core, this is considered a renewable energy. Most common geothermal power plants release no greenhouse gas emissions.
Geothermal power can also be used on an individual basis. Geothermal heat pumps can heat your home, cool your home, and even supply hot water to your home. They cost more than traditional air-source heat pumps, but the extra cost is returned to you as you save money each month. The return on your investment typically happens within 5 - 10 years
An alternative is a dual-source heat pump, which combines geothermal and air-source technologies. These heat pumps work almost as well as geothermal heat pumps, but without the expensive price tag.
Wind energy has been harnessed for years in the form of windmills and turbines. Personal electric wind systems are available for people who live on at least one acre of land and have minimal windbreaks. Wind turbines are still available to pump water from wells. Wind power plants are becoming available to provide electricity to your home for a minimal price. The amount of wind power utilized has doubled in the last three years, but the cost of the turbines and visual side effects of the large turbines across a landscape are deterrents.
Hydropower has been around for years in the form of waterwheels, dams, wave power, and vortex power. Hydroelectricity is power that is derived from the force and kinetic energy of water to produce electricity. Hydroelectric power now supplies about 19% of the world's energy and this number is growing. More dams and other water-powered power plants are being constructed because they leave a lesser environmental carbon footprint and they're less expensive to build than traditional power plants.
Harnessing the heat from the sun and transforming it into a usable form generates solar electricity that can be utilized for both residential and commercial uses. Solar receptors are designed in ways to take in the maximum amount of sunlight. Solar electricity is available to purchase in some parts of the southwestern United States.
Personal solar power generators are also available. They can be used to generate electricity, heat homes, heat water and provide light. Of course, you can use the sun's energy for free by hanging your laundry out on a clothesline to dry. Actually, when you do something simple like that, you're using both solar and wind energy to dry your laundry. What did it cost you? Perhaps the cost of a rope and some clothespins, but that's all!
Despite the overwhelming amount of solar power available for use, only a small fraction is harnessed and used by companies or homeowners. That is why we created this site! :-) I'd like to encourage everyone to consider using solar energy if they can possible do so. Other renewable energy sources like hydro and wind power also derive energy from the sun and can be used in a number of ways to power your home with renewable, environmentally friendly energy sources.
New green technology innovations are constantly being developed in an effort to discover new ways to use green energy. Solar power, hydropower, geothermal power, and wind power are all capable of generating electricity and performing other functions without releasing greenhouse gasses and other pollution into the environment. These green power sources are much better for the environment, which means the world will be a healthier place for future generations!
Every year, the amount of power used from renewable resources increases. One day in the future, oil, coal, and all the other fossil fuels will be gone and the earth will be completely reliant on these safer, natural energy sources It is up to each of us to help make this eventual transition from dependence on fossil fuels to solar, hydro, wind, and geothermal power easier. Why not begin preparing for that time now and begin using green energy sources? I hope our site can be of help to you in this!
