Energy sources

3. We put the on the roof to get energy from the sun
6. The most abundant greenhouse gas
8. That can be harnessed by large blades on wind turbines, which use it to generate electricity for residential and commercial purposes.
9. Fuel made from from plants or animal waste
10. Organic matter, such as wood, crops, seaweed and animal waste. It gets its energy from the sun and can be used to produce electricity.
11. Also known as petroleum – can be extracted and refined in order to make products such as gasoline, diesel and jet fuel.
13. Energy that comes from the heat generated by the Earth, such as volcanoes or geysers. It can be used to produce electricity, and provide heat and hot water.
17. Energy that comes from the force of moving water. Hydropower plants use dams to capture water energy and convert it to electricity.
18. Energy is released when atoms' nuclei are fused together (fusion) or split apart (fission). Nuclear power plants produce electricity through nuclear fission.
19. Human energy units
20. Unit of electrical power.

1. The main light source on Earth, a renewable energy source.
2. Energy sources that will run out because the supply cannot replenished as fast as it is used, e.g. oil.
4. energy sourced that will never run out (e.g solar power)
5. What type of electricity bulb is mos efficient and has the longest life
7. A flammable black hard rock, comes from the remains of plants that died hundreds of millions of years ago. It has the highest level of carbon of all fossil fuels.
12. That was formed from the remains of tiny sea plants and animals that died millions of years ago. It is mainly composed of methane.
14. The rate system, which determines the charge for electricity consumption.
15. Electricity work powered in a given unit of time.
16. A device that generates electricity through a chemical reaction, used in electrical devices such as wall clocks, electronic thermometers, and more.
