Energy and conservation

Page

Dust and gases in the air can lead to smog above large industrialised cities

A hole is developing in the ozone layer which therefore will not filter out harmful ultra-violet rays from the Sun

Slide 13

We need to conserve our fossil fuels

The electricity we produce from burning fossil fuels could also be made using renewable energy resources

It makes sense to save the oil we have left for making fuel for transport and for making plastics

We could try to save wasting energy from fossil fuels during domestic use in our homes and from waste transport consumption of fuel

Slide 14

Alternative energy sources

Wind energy

Hydroelectric energy

Solar energy

Tidal energy

Nuclear energy

Geothermal energy

Biomass energy

Slide 15

Problems with nuclear fuels

Nuclear power stations can produce large amounts of energy from small amounts of nuclear fuel. (Radioactive materials naturally release heat)

Nuclear radiation is extremely dangerous

High safety standards are needed

Waste materials stay radioactive for thousands of years

There have been some disastrous accidents at nuclear power stations which have affected all living things in the area

Slide 16

Write an article for a newspaper or a magazine, outlining the need for energy conservation

Plan:

Fossils fuels: uses

Fossil fuels : why we need to conserve them

Fossil fuels: problems of pollution

Alternative energy sources (advantages & disadvantages)
