hydro power vs. solar energy

When I first started I was using hydro power then I went to solar energy because solar energy is far by the most earths available energy solar and solar is made from the sun and hydro power is made from water the sun is better because went the sun goes down were well be no more ride to go on at the fair and the cost for solar energy is 0.16 and the cost for hydro power is 0.09 I thank the cost for solar energy is more than hydro and hydro powers earth contains hot water. People us water more than 2,000 years. In 1880’s scientists learned that flowing river to and I put in the cost that 7% in us electricity 29%

hydropower

HYDROPOWER

 

Well people that

do hydropower pick up water and make it into energy

Or electricity. While hydropower creates almost no

Pollution it can cause changes to the environment that

Affect animals and plants. People can get water and make it

Into electricity. Hydropower is the renewable energy

Source that produces the most electricity in the

United States. About 7% total US electricity

Generation and 56% of generation from all renewable

In 2012. Hydroelectric dam are expensive to build.

HYDROPOWER vs. WIND POWER

Well I think you should pick hydropower

Because people need electricity. People

Need electricity because people can’t see with no lights so we get water and make it into energy or electricity. While hydropower creates almost no pollution it can cause changes to the environment that affect animals and plants. People

Can get water and make it into electricity.  Wind power

Is bad because it can create tornado and hurricanes.

People like snow but they don’t like when the

Wind is too hard.  People don’t like when the

Wind is too cold because have colds and some

People freeze to death.

All about solar power

 

SOLAR ENERGY COMES FROM THE SUN. WE USE SOLAR ENERGY A LOT. SOLAR COMES FROM SOLAR PANELS. SOLAR COST IS NOT VERY COST EFECTIVE. SOLAR ENERGY IS FAR BY THE EARTH’S MOST AVAILABLE USER. SOLAR ENERGY IS REALLY GENERATED WHEN PHOTOVOLTAIC CELLS CONVERT HEAT FROM THE SUN DIRECTLY INTO ELECTRITYCY THOSE WHERE SOME FACTS I KNEW ABOUT SOLAR.
