Hydropower and Natural gas

By: Sarah and Demetrius

How is this energy used to produce electricity and is it

renewable or nonrenewable?• Hydroelectric energy is used to produce

electricity. As the water falls it has kinetic energy as it turns the wheel the kinetic energy is converted into mechanical energy. If the wheel is connected to a generator the mechanical energy is going to change into electrical energy.. Hydropower is renewable because water is constantly cycling from the source to the air then the land and back to the source.

How long have humans used this energy source and how is

it used in present day?In ancient times the Romans used

water wheel to operate pumping mechanisms for aqueducts. the Romans were thousands of years old. In present day hydropower is harnessed by dams that are built on a water source. Water wheels also are used to generate energy.

Advantages• After the dam is built

hydroelectric energy is inexpensive. This source of energy causes little pollution. It could also reduce the demand of fossil fuel which cause big amounts of air pollution.

Disadvantages • Hydroelectric energy is not available

any where. It can only be produced were large amounts of water can be harnessed . Using hydropower can disturb the migratory path of salmon and steelhead.

Natural gases• How is this energy used to produce electricity? When natural gas is burned it releases heat and electricity.

Advantages • Natural gas burns

more cleanly than the other fossil fuels.

• This fuel for vehicles are cleaner than diesel and gasoline.

Disadvantages • Even though it is

cleaner than coal and oil, it still has a large amount of carbon dioxide a greenhouse grasses.

• It can leak, causing an explosion.

• It’s very flammable.

How is the energy formed used in present day?

Natural gas is used for… Kitchen stovesCarsPlanes and shipsAlso producing heat and electricity.

The End!!!!!!!! Try not to laugh!!!!!!
