Slide 4 - Slide

C3.2: ENERGY OF THE FUTURE

Slide 5 - Slide

ENERGY TRANSITION

The shift from using fossil fuels to using sustainable sources.

Slide 6 - Slide

Think:

What are the 5 sustainable energy sources and

name a disadvantage.

Slide 7 - Slide

SOLAR ENERGY

Electricity generated sustainably using solar penals.

You can also use the sun to heat water.

Slide 8 - Slide

WIND ENERGY

Electricity generated sustainably using wind turbines.

Slide 9 - Slide

HYDRO-ELECTRICITY

Sustainable energy that is generated using falling water.

Slide 10 - Slide

BIOMASS

Organic materials such as vegetable oils, wood and biodegredable waste (vegetables, fruit and garden waste).

Slide 11 - Slide

GEOTHERMAL ENERGY

Sustainable energy from the natural heat deep inside the Earth.

"Earth heat"

Slide 12 - Slide

CHECK HOMEWORK

Slide 13 - Slide

Wind, sun & biomass

4 a They are in coastal areas and in the sea, where there is a lot of wind and they cause the least nuisance to people.

b See W4 on next dia.

c solar panels, wind turbines and energy conservation (homes facing south)

Slide 14 - Slide

Slide 15 - Slide

USE FIGURE 8 & 10

5 The level of carbon dioxide does not change: CO2 is created when wood is burned. The CO2 is absorbed by trees; the wood from the trees is used to generate energy.

6 a Oil palms for biofuels instead of tropical rainforest.

b Large areas of tropical rainforest were removed for cultivation of oil palms, a loss of nature areas.
