Study Notes
- Fuel produces heat energy on burning.
- Wood is a form of fuel that can be used in houses.
- Biofuels cannot be replaced as quickly as they are used.
- Gases released from burning fossil fuels always pollute the air.
- If we use renewable resources of energy instead of fossil fuels, the Earth's temperature will decrease.
- Coal is formed under the Earth's surface from the remains of dead plants.
- We must conserve solar energy and wind energy.
- Green plants are not found deeply under the Earth's surface.
- All the following are used to generate electrical energy, except glass.
- The amount of fossil fuels will decrease if people don't conserve their usage.
- Some forms of fuel can be used in cooking such as wood, coal and gas.
- The generator in the electric power station changes mechanical energy into electrical energy.
- Using renewable resources of energy costs more money than using fossil fuels.
- Different forms of fuel can be classified into two main types which are solid and liquid.
- Water is a liquid renewable resource of energy.
- Wind energy is a gaseous renewable resource of energy.
