Fossil-fuel energy
Wind energy
Geothermal energy

3. Renewable energy
Renewable energy is energy which comes from natural resources such as sunlight, wind, biomass, rain, oceans and geothermal heat. So the market for renewable energy technologies has continued to grow. Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization.

4. Non renewable energy
Coal, oil, natural gas (the so called “fossil fuels”) and uranium are non-renewable resources that once exhausted can never be returned to their original form.
No doubt our planet is full of energy resources but it is our duty to exploit only those reserves that cannot cause harm to the environment.

5. Renewable energy Types of energy Advantages Disadvantages Sun energy
Energy source is free; causes no pollution
Expensive; supply of sunlight can be interrupted
Wind energy
Only practical in areas with strong steady winds
Hydroelectric energy
Station cheap to operate; causes no pollution
Stations can only be built in certain locations
Geothermal energy
Only practical in a few locations
Biomass energy
The fuel tends to be cheap; less demand on the Earth’s resources
By burning the fuel, it makes greenhouse gases

6. Non renewable energy Types of energy Advantages Disadvantages
Fossil – fuel energy
Efficient, reliable
Limited supply of fuel in the world; waste of resources; pollution
Nuclear energy
Requires little fuel; produces little air pollution
Produces radioactive waste; stations expensive to build
