1. "Energy Resources" is NOT the same thing as "Types ofenergy"."Energy Resources" is about ways of getting energy so wecan generate electrical power.

Introduction: Coal, oil and gas are called "fossil fuels" because they have been formed from the organic remains of prehistoric plants and animals. Fossil fuels are not a renewable energy resource. Once burned, there isnt any more.How it works Coal is crushed to a fine dust and burnt. Oil and gas can be burnt directly. Afterrefining.AdvantagesDisadvantages Very large amounts of The main drawback of fossilelectricity can be generated in fuels is pollution.one place using coal, fairly Burning any fossil fuelcheaply.produces carbon dioxide, which Transporting oil and gas to the causes warming of the Earth.power stations is easy. 4. Introduction: Nuclear power is generated using Uranium, which is a metal, mined in various parts of the world. Some military ships and submarines have nuclear power plants for engines. Nuclear power produces around 11% of the worlds energy needs, and produces huge amounts of energy from small amounts of fuel. Nuclear energy is not renewable. Once weve dug up all the Earths uranium and used it, there isnt any more. How it works:AdvantagesDisadvantages Nuclear power is not very It is very, very dangerous.expensive. It must be kept safe from Does not produce smoke or earthquakes, flooding, terroristscarbon dioxide. 5. Introduction: Weve used the Sun for drying clothes and food forthousands of years, but only recently have webeen able to use it for generating power. The Sun is 150 million kilometers away, andamazingly powerful. Just the tiny fraction of the Suns energy that hitsthe Earth is enough to meet all our power needsmany times over. Solar power is renewable.How it works: There are 3 main ways Solar cells Solar water heating Solar boilersAdvantages Disadvantages Solar energy is free - it needs Doesnt work at night.no fuel and it is pollution free. Very expensive to build solar Solar power can be used power stations, although thewhere there is no easy way to cost is coming down asget electricity to a remote technology improvesplace. 6. Introduction: Weve used the wind as an energy source for along time. The Chinese were using wind power to pumpwater for irrigating crops 4,000 years ago, andsailing boats were around long before that. Wind power was used in the Middle Ages, inEurope, to grind corn, which is where the term"windmill" comes from. Wind Power is renewable.How it works:AdvantagesDisadvantages Wind is free, wind farms need The wind is not alwaysno fuel.predictable some days have no Produces no waste orwind.greenhouse gases. Suitable areas for wind farms A good method of supplyingare often near the coast, whereenergy to remote areasland is expensive 7. Introduction: The tide moves a huge amount of water twiceeach day, and harnessing it could provide a greatdeal of energy. Although the energy supply is reliable andplentiful, converting it into useful electrical poweris not easy. Only around 20 sites in the world have beenidentified as possible tidal power stations. Tidal energy is renewable.How it works:Advantages Disadvantages A barrage across an estuary is very Once youve built it, tidalexpensive to build, and affects apower is free. very wide area Tides are totally predictable. Many birds rely on the tide so that they can feed. Fish cant migrate, unless "fish ladders" are installed.
