PostSubject: Renewable Energy   Wed Jul 22, 2009 10:55 am

There are many types of Renewable Energy that are growing more and more in popularity such as Geothermal, Solar, Tidal, Wind, Bio-fuel, Hydropower, etc.

Geothermal Energy


Geothermal power (from the Greek roots Geo, meaning earth, and thermos, meaning heat) is power extracted from heat stored in the earth. It is a renewable source of energy due to the cycle of heat beneath the earth's crust is potentially unlimited. Plants can be build over geysers, hot springs, or volcanoes to gather the energy stored inside their heat.



Bio-fuel - Biomass

Biomass, is a renewable energy source, biological material derived from living, or recently living organisms,[1] such as wood, waste, and alcohol fuels. Sounding similar to fossil fuels but different due to fossil fuels being from ancient dead organism instead of recent. Fossil fuels takes ages to become a potent source of power while biomass can be used with a living organism or recently living.



Hydropower

Hydropower, hydraulic power or water power is power that is derived from the force or energy of moving water, which may be harnessed for useful purposes. In modern times dams contribute to hydropower, but this technique has been used centuries before by the use of water wheels, which turned by the moving force of power generate power for mills and machinery. It is a highly potent source of renewable energy as the movement of water is simple and continuous.



Solar Energy

Solar power is the conversion of sunlight into electricity by using photovoltaics otherwise known as solar cells. This power relies on the sun which is constantly blasting energy to earth continuously. If solar panels are made that can attract the energy of the sun during the day and reserve some for the night, this can be a highly potent source of energy.



Tidal Power


Tidal power, sometimes called tidal energy, is a form of hydropower that converts the energy of tides into electricity or other useful forms of power. The tides move the turbines under water causing energy to be created similar to a wind turbine which uses wind. This continuous movement is suitable for a renewable source of energy due to it being virtually limitless.



Wave Power


Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work — for example for electricity generation, water desalination, or the pumping of water (into reservoirs). When a wave moves over once of these machines the force generated by the wave is tabbed by the sensors converting the force into usable energy. This is a highly potent source of energy due to the continuous movement of waves on the ocean and even on other bodies of water.



Wind Power


Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. Wind is a continuous force on the planet and will continue to be so in the foreseeable future. When wind strikes a wind turbine the fans on it are moved generating electricity which is converted into usable power.



Feel free to discuss any other forms of renewable or future energy that I left out, or even give some ideas of your own thoughts on future energy.

The only issue is cost, and intelligence. The prior is too high, and the ladder is too low in our government. Not too mention the oil company has so much power it's hard to break loose into another source of power... Sigh....
