1 Renewable and Non-Renewable Energy Year 7 Science
2 What is Renewable and Non-Renewable Energy? Key WordsRenewableNon-RenewableEnergyGenerateElectricity
3 What is the difference between Renewable and Non-Renewable Energy?
4 What is Renewable Energy? Renewable means that it can be used over and over again. It will not run out.Geothermal power Hydroelectric powerSolar PowerBiomass fuelWind turbinesWave turbinesNatural gas
5 Renewable energy won’t run out as long as the Sun still shines…
6 The wind turbines will always blow… … And turn turbines to generate electricity.
7 Plants will always grow… … and can be burnt to release heat energy (Plants get their energy from the sun through photosynthesis)
8 Waves will always be made… …and drive generators to make electricity
9 Solar Cells will always work… … and change light to electricity energy
10 What is Non-Renewable Energy? Non-renewable means supplies will run out eventually.OilNuclear powerGasCoal
11 …and only a minute to burn!! Fossil Fuels took millions of years to develop……and only a minute to burn!!
12 Once they’ve been taken from the Earth – That’s it they have gone!! (unless you’re going to wait around a few more million years for more to be made!!)There will come a time when we can’t find any more and then we could have a problem!
13 Crude oil is vital for making all sorts of useful plastics and medicines, so its not such a good idea to keep burning it to make energy… Can you think of ways in which we can help protect Non-Renewable Energy?
14 The answer is:Save Energy - turn lights off, drive cars with small engines etc…Use more Renewables – Energy sources like wind power, biomass, wave power, solar power, tidal power are all renewable.Renewables don’t cause acid rain or the greenhouse effect – they could protect the environment
