Fossil fuels and nuclear energy

What is a fossil fuel

A hydrocarbon containing material formed naturally in the earth's crust from the remains of dead plants and animals.

What are three main types of fossil fuels

Crude oil
Coal
Natural gas

Fossil fuels can be burned to provide heat, what can the heat be used for

Direct use (cooking)
Power engines
Generate electricity

How long does it take fossil fuels to form

Millions of years

What are the advantages of fossil fuels

They are cheap
Can be used in any condition
Our current infrastructure uses them

What are the disadvantages of fossil fuels

They are a limited resource, so we will run out
They produce carbon dioxide which contributes to global warming
They produce toxic gases like carbon monoxide and sulfur when burned

What is nuclear energy

Energy obtained by nuclear reactions

What can nuclear energy be used for

Genersting electricity

What are the advantages of nuclear energy

They do not produce pollutants
Can be used in any conditions
Very unlikely to run out

What are the disadvantages of a nuclear energy

They are finite
It is expensive
Nuclear power stations produce radioactive waste
