1. Generate Electricity

2. Video Generate Electricity

3. Different types Thermal power – Solar energy – Coal – Gas – Nuclear Hydroelectricity Wind power

5. Electricity generating is very important, because most of the compliances in todays life work with electricity. Without electricity, a lot of businesses and factories will stand still.

6. Schools need electricity to switch on lights, to use the intercom, switch on fans, etc. At factories the machines will come to a stand still and processing will stop or slow down.

7. Coal generating Coal is mined It goes to the factories At the factories the coal is burned to get steam, the steam goes through tunnels to turbines. Turbines turn and the coils of the generator turns that gives us electricity.

8. From the generator it goes to step up transformers that increase the voltage. It goes through high voltage lines to sub stations. From the sub stations the voltage is decreased to go to our homes for us to use.

10. Transformer We get two kinds of transformers Step up transformer and a step down transformer. Transformers can take a low voltage to a higher voltage or the other way around depending on the number of coils.

11. Thermal power plant

12. Thermal generating STEAM is used to generate electricity. We get steam when we boil water with something. We can use coal, gasses, sun and nuclear energy

13. Hydroelectricity Electricity is generated by the use of water. Water turns the turbines if it flows past them. It is pumped back to the dam and used again.

15. Wind generating We use the wind to generate electricity. The turbines is connected to big wings that turns when the wind blows.

16. Advantages and disadvantages All types of generating has advantages and disadvantages.

17. Thermal power Advantages – Fuel is quite cheap. – Can be built anywhere – Use less space than Hydro electrical plant – Less expensive than diesel powerplant

18. Disadvantage – Pollution from the smoke of the fuel burning. – More expensive than Hydro Power plants

19. Hydroelectricity Advantages – Can be used over and over – Can be generated 24/7 – Doesn’t cause pollution.

20. Disadvantages – More expensive to build than thermal plants – Can cause floods and it is dangerous for nature.

21. Wind power Advantages – The wind is for free. – No pollution – Doesn’t take a lot of land space

22. Disadvantages – Wind changes the whole time and doesn’t stay consistant – Wind turbines makes a lot of noise.
