Wind

Wind is also renewable because it dosent use a factory

Wind doesnt cause pollution to the enviorment

It produces with no toxic gas or fuel

disadvantages

Doesnt make energy when they dont go to wind

It kills over 100 birds when the birds fly.

Its a lot of money to make windmills for energy.

When the wind blows the windmill it makes energy

Wind is from the outdoors and goes to the windmill and makes energy.

Nuclear

Dosent produce with green house gas

Nuclear cant turn into a nuke.

Uses low gas for more energy

DisAdvantages

Nuclear gas can be used as a weapon when the terrorist use it.

They renew the energy with fossil fuel.

Its really toxic that it could kill people

It works by putting nuclear toxic into a special tank to produce energy.

Nuclear is a toxic gas that they use to get energy

Solar

Solars are not balanced too.

Solars dont produce energy at night.

When its winter or raining it wont produce energy.

Solar does not highly effect the bill

It dosent poison the enviorment

Solar is renewable since it doesnt use gas.

Solar works when there are solar panels being shined by the sun.

solar is a special way to make energy with the sun

Fossil Fuels

You can use coal to make fossil fuels for energy and you can get coal in the mines.

They make a large amount of energy in the factory.

Oil spills in the water and could be bad or poisonous to the sea creatures.

Fossil fuels can cause more pollution when you keep adding more fossil fuels.

It's really bad for the environment. The effects of it can hurt the enviorment and health.

So fossil fuels work by when they burn it up to make energy.

Fossil fuels are gases like coal, oil and natural gas. They belong in factories that produces energy.

Hydro-Electric

Disadvantages

Some seasons can cause high risk for hydro electric.

Hydro-Electric rivers can cause dam construction

It can affect the water stream by changing the quality

Advantages

It doesn't affect or damage the enviorment

You'll need no fuel to produce energy

Its a renewable energy resource

Hydro electric is where energy comes from the waterfall.

When water goes through the bridge energy starts to produce.
