Solar energy Info #1

Solar energy is created by panels converting the sun's rays into electricity by exciting electrons in
silicon cells using the photons of light from the sun.

Solar energy can be used to supply renewable energy to your own house and businesses.

The United States mostly use this energy on the roof of Space headquarters it increases renewable
energy sources to 25 percent of all energy consumed by the year of 2025. Solar energy deployment
increased at a record pace in the United States and throughout the world in 2008 according to industry
reports.



Solar energy Info #2

Solar panels are a great way to offset energy costs, reduce the environmental impact of your home and
provide a host of other benefits, like supporting local businesses and contributing to energy independence.

Some advantages using this energy is it reduces electricity bills, low maintenance cost, and diverse
applications.

The disadvantages of this energy Solar panels is a great way to offset energy costs, reduce the
environmental impact of your home and provide a host of other benefits, like supporting local businesses
and contributing to energy independence. Solar panels also uses a lot of space to collect as much sun as
possible.



Wind Energy Info #!

Wind energy is created by wind turbines rotor and rotor blades it converts wind energy into
rotary movement. It is used for doing work rotational energy is converted to electricity with the
help of a generator.

People have been using windmills for thousands of years for grinding grain or pumping water.

wind turbines made of metal were used in American ranches and homes for pumping water into
the plumbing system of the house or into the watering trough of cattle.



Wind Energy Info #2

The advantage of this energy is that it does not pollute the air like power plants that it rely on
combustion of fossil fuels like coal or natural gas.

Wind turbines can be built on farm or ranches farmers and ranchers can continue to work the land
because the wind turbines use only a little bit of the land. Wind power plant owners make rent
payments to the farmer or rancher for the use of the land this provides llandowners with additional
income.

The disadvantage of this energy is that turbine blades can damage local wildlife. Birds can get killed by
flying into a spinning turbine. Good wind sites are often located in remote location far from cities where
the electricity is needed.



Tidal Energy Info #1

Tidal energy is created by by tidal energy generators underwater turbines are placed in areas with high
tidal movements its designed to capture kinetic motion.

Tidal energy can be used for the mechanical crushing of grains in grainmills however with fossil fuels this
usage of tidal energy is low.

Turbines are most effective in shallow water. This produces more energy and allows ships to
navigate around the turbines.

The United States does not have any tidal power plants, and it only has a few sites where tidal
energy could be economical to produce



Tidal Energy Info #2

disadvantage of tidal power is the effect a tidal station can have on plants and animals in
estuaries of the tidal basin. methods for generating electricity from tidal energy is a relatively
are relatively new technologies.

The advantage of this is it does not release greenhouse gases or other pollutants into the air. It
is also a cheap energy source. Water has 1000 times higher density than air, which makes it
possible to generate electricity at low speeds.
