10. Wind Power

11. Modern Wind Power

12. What is Good? University of Delaware: The total energy power which is “economically viable” is more than 7 times the world’s demand for electricity Uses very little land Land around it is still usable

13. What is Bad? The wind does not always blow

14. Hydropower

15. How does hydro power work? Water is built up behind the dam and then allowed to flow through it. Illustrations taken from RenewableEnergyResource.net

16. How does hydro power work? Water is built up behind the dam and then allowed to flow through it. The flow of water is then channeled through a turbine, which spins the generator Illustrations taken from RenewableEnergyResource.net

17. How much power can one dam produce? The Three Gorges dam produces as much energy each year as: “Great Wall across the Yangtze” -PBS 25 million tons of crude oil 50 million tons of coal 15 nuclear power plants

18. What’s the catch? Restricted water flow downstream
