Some text here about the topic of discussion

Zig Ziglar

You don’t have to be great to start, but you have to start to be great.

​How does Fossil Fuel Power Station works

1. Burning of fuel (coal, oil or natural gas)

2. Energy is transferred by heating

3. Heat boils water

4. Boiling water produces steam

5. Steam turns turbine

6. Turbine turns generator

7. Generator generates electricity

Advantages and Disadvantages

Advantages	Disadvantages
• Reliable resource •Contain large amount of energy in the chemical energy store per kilogram	• Fossil fuels are finite and will not last forever •Non-renewable •Release carbon dioxide – a greenhouse gas which causes global warming and contributes to climate change •Release sulphur dioxide and nitrogen oxides which cause acid rain. •Smoke contains lots of fine particles that can cause smog and breathing difficulties •Taking fossil fuels from the ground disrupts ecosystems

Renewable and Non-Renewable Energy Sources

​Renewable vs Non Renewable

Energy resources that cannot be replaced. These resources will run out.

Energy resources that can be easily replaced.

These resources will not run out.

Energy store and transfers

Energy

•energy is what makes everything happen.

•It is also known as the ability to do work.

•The units of energy are Joules.

​Different energy store

Energy Store	Description
1.	Energy an object has due to its
2.	Energy stored in
3.	Energy stored due to its
4.	Energy stored in a
5.	Energy a substance has due to its
6.	Energy stored in the
7.	Energy stored in
8.	Energy stored in

​Types of energy Transfer

​Energy transfer diagrams show each energy store and the process taking place as it is transferred.
