1. Non-Renewable
Energy

2. The Sun - the ultimate source of energy
The original source of most energy resources.
Plants store the Sun’s energy
in photosynthesis.
Animals then eat the plants.

3. The Sun - the ultimate source of energy
natural gas
oil
The Sun
The original source
of most energy
resources.
coal
biomass
waves
wind
food

5. Non-renewable energy resources
Non-renewable types of energy can only be used once. There is a finite amount of these materials on the Earth so they will run out eventually.
Non-renewable resources make up approximately 95% of the world’s energy.
fossil fuels
nuclear
coal
gas
oil
fuelwood
Non-renewable energy
biomass
mineral

6. Impact of burning fossil fuels – Greenhouse Effect

7. temperature record, rising sea levels
Effects of Global Warming?
Environmental
temperature record, rising sea levels
increase in the frequency of some extreme weather conditions (heat waves, droughts, forest fires.
Social
agriculture and food production around the world due to: the effects of elevated CO resulting in decreased crop yields.
increase the number of people at risk of hunger.
Infectious disease vectors (transmitted by the bite of infected by mosquitoes.
through changes in water, air and food quality and changes in ecosystems, agriculture, industry and settlements and the economy.
Migration and conflict (conflicts may be linked to competition over natural resources )

8. What Can We do? International You …
Kyoto Protocol – International binding agreement set for 37 industrialized countries and the European community for reducing greenhouse gas (GHG) emissions .
These amount to an average of five per cent against 1990 levels over the five-year period
You
Grow your own food
But local produce
Turn off lights and any other electrical products, insulate houses
Use energy efficient products
Use Eco Products (designed in a sustainable way)
Use renewable energy instead of non renewable
Buy durable products rather than disposable
Only buy products that have been made in a sustainable way.
REDUCE, REUSE, RECYCLE. …

9. Combustion of fossil fuels
How can these pollutants be reduced?
fluidised bed technology
(limestone is burnt with the coal so the sulphur remains with the limestone)
burn coal with less sulphur
gas flue desulphurisation
(water is sprayed down the chimneys and this turns the gases to sulphuric and nitric acids)
construct taller chimneys
or..we could use more nuclear or renewable energy
or..we could use less energy, more efficiently…

10. Nuclear
Nuclear energy is made from the mineral, uranium. These power stations are often located by the coast or on estuaries where there is water for cooling.
France has 55 nuclear power stations.
This one is in the Rhone Valley.

11. Nuclear
0ne tonne of uranium can produce the same amount of electricity as tonnes of coal.
uranium =
tonnes of coal
What are the other advantages of nuclear power?

12. Nuclear or fossil fuels?
What about nuclear waste?
Nuclear energy is the clean fuel of the future
Fossil fuels cause pollution
Nuclear power is too costly to be used for heating and transport
Fossil fuels will run out
There is worry about nuclear disasters
Terminals and refineries take up space
Nuclear energy will cause a loss of mining jobs
Only small amounts of uranium are needed in nuclear power stations
Oil and gas could be exhausted by 2040
It is very expensive to decommission old nuclear power stations
There have been no serious nuclear accidents in Britain
