Green Power:
Green power is energy that is obtained through renewable sources and also has little effect on the environment. Common sources of green power include:

1. Geothermal
Geothermal power is obtained through wells drilled into geothermal reservoirs that are below the earth’s surface. A geothermal power plant can then convert the hot water or steam that was in the reservoir to energy. Geothermal reservoirs are also used on a smaller scale to heat homes and other areas.
Downfalls to this type of power come mostly from the research it takes geologists and other scientists to find geothermal reservoirs.

2. Hydro and Wind
Energy obtained through water and wind sources have the same basic principle behind them. Either wind or water is used to turn a turbine which then creates electricity that can be stored for later use.


Downfalls to using wind for power:
Wind power is collected through the use of wind turbines which are large and needed in quantity to obtain a useful amount of power from the wind. The amount of power that is obtained is also irregular due to the irregularities in wind and wind strength.
Downfalls for using water to generate electricity:
Hydroelectric power on a large scale needs a damn for water to run through to get power. Creating a damn, like the construction of the Hoover Dam, floods the land and destroys the habitats of creatures living upstream from the dam.

3. Solar
Solar power uses special panels that capture energy in the suns light and convert it into electricity that can be stored and used.

Downfalls to solar power can come from the initial cost of installing solar panels, and the need of sunlight to generate electricity.
