Flashcards in Chapter 3- Energy Resources Deck (10):
1

In a power station-

Fuel heats water
Water turns to steam
Steam turns a turbine
The turbine creates energy

2

Non renewable resources-

Coal
Wood
Nuclear
Oil

3

Solar cells-

Cells transfer light and electrical energy

It is renewable
Cheap to run

Unreliable
Expensive to buy
Lots of energy is needed

4

Geothermal-

Where radioactive material is found in the earth and is used

Reliable
Renewable

Limited to where it can be used and found

5

Nuclear-

Nuclear power stations use radioactive materials such as uranium. The nucleus’ are split into two which creates energy

No greenhouse gases
Lots of electricity created

Creates radioactive waste
Which is expensive to get rid of

6

Wind-

Wind turns turbines which creates electricity

Renewable
No greenhouse gases

Can be an eyesore
Unreliable
Noisy

7

Wave-

Waves make a bouy float up and down

Renewable
No greenhouse gases

Need to be strong enough to withstand storms
Eyesore

8

Hydroelectric-

River flows down a hill and turns turbine

Renewable
No greenhouse gases

Needs a large area
May destroy animals habitats

9

Tidal-

Water is trapped behind a high tide then this is released through a generator

Renewable
No greenhouse gases

Can effect the rivers flow
Destroy habitats

10

What is a biofuel?

They can be collected from manure, sewage or decaying rubbish. Biofuels are reusable because the biological materials can re grow
