//__**Work, Energy, and Power & Resources**__//


 * __-Renewable Resources:__**

__- Solar energy-__uses mirrors and photovoltaic cells to collect solar energy. mirrors reflect light to a central point where water is boiled and the steam is used to turn a turbine.

__Photovoltaic Cells__ -Take light and transform it into electrical energy.

__Tidal Power-__ Uses submerged generators that rely on incoming and outgoing tides to generate power.

__Hydroelectric-__ Uses the power of falling water to generate electricity by spinning turbines which make AC current.

__Wind Power-__ Spins gigantic windmills which turn a turbine/generator which produce AC current.

__Geothermal-__ The use of the principle stating that water is the same temperature underground all the time, which is used to heat or cool buildings. Also, the use          of super-heated steam underground to spin turbines.

__Nuclear-__ The use of either enriched uranium and regular water, or the use of regular uranium and deuterium oxide to produce a controlled fission reaction. The controlled fission reaction creates steam which spins turbines creating current.
 * __Non-Renewable Resources:__**

__Coal-__ Coal furnaces boil water creating steam to turn turbines.

__Natural Gas-__ Burners heat water creating steam to turn turbines.

__Oil-__ Oils is burned to create steam which turns turbines.

Power is mostly generated from non-renewable resources, whereas renewable resources create a minimal around of the power used in the world.


 * __Calculating Work and Power__**

Work = The Change In Energy

Power = The Work Done/Time
