The document discusses various energy resources including fossil fuels like coal, petroleum, and natural gas which are non-renewable. It also discusses renewable resources for generating electricity such as hydroelectric, geothermal, wind, solar, nuclear, and biomass. For each type of energy source, it provides some background on how it works and highlights potential advantages and disadvantages.
14. - Although not much waste is produced, it is very, very dangerous. It must be sealed up and buried for many years to the radioactivity to die away. - Nuclear power is reliable, but a lot of money has to be spent on safety . If it does go wrong, a nuclear accident can be a major disaster. Disadvantages
21. - Once the dam is built, the energy is free. - No waste or pollution produced. - Much more reliable than wind, or solar power. - Water can be stored above the dam ready to cope with peaks in demand. - Electricity can be generated constantly. Advantages

23. Wind power Windmills are built together in a “wind farm.” The use of a windmill to drive an electric generator.
34. We even use solar power in orbit! Why would that be a good way to power satellites? Video clip on solar power

36. Doesn't work at night. Very expensive to build solar power stations. Solar cells cost a lot to make. Can be unreliable unless you're in a very sunny climate. Disadvantages
