Environmental Effects 12 July, 2014 Keywords Renewable, non-renewable, carbon dioxide, global warming, sulphur dioxide, acid rain, Renewable, Habitats, Fossil fuel, Nuclear, Night , Decommission, Hills, Hydro, Generator, Not reliable, Estuary.
All students should be able to: Describe what global warming and acid rain are. Most students should be able to: Describe the causes of global warming and climate change and acid rain. Describe the environmental effects of renewable energy resources. Some students should be able to: Evaluate the advantages and disadvantages of different energy resources and make a judgment on how we should power the UK. Outcomes
How certain can we be? Each of these lines represents a computer climate model for the next century. The grey area contains the predictions for several climate models. All predict a warming, but there is a range of 5ºC between different models.
Coal, oil, gas and nuclear Non-renewable energy sources Advantages Disadvantages Cheap fuel costs Costs a lot of money to decommission a nuclear plant Good for “basic demand” Reliable Fuel will run out Short start-up time for gas and oil Pollution – CO2 leads to global warming and SO2 leads to acid rain Nuclear produces little pollution
Wind, tidal, hydroelectric and solar Renewable energy sources summary Advantages Disadvantages Zero fuel costs Unreliable (except for hydroelectric) Don’t produce pollution Expensive to build Hydroelectric is good for a “sudden” demand Tidal barrages destroy the habitats of wading birds and hydroelectric schemes involve flooding farmland Solar is good for remote locations (e.g. satellites)

Animation Greenhouse effect
Making acid rain Add a few drops of indicator to distilled water (The matches give off CO2 and SO2) Burn some matches in a jar and put the lid on When the matches have burnt out add the indicator/water mix. It will turn yellow if acid if the SO2 dissolves into the water to make H2SO4 (Sulphuric acid) Acid Rain
Fossil fuelled power stations give off many unwanted ________. One is _____________ – which contributes to the greenhouse effect. It absorbs ___________ radiation which is then reradiated to Earth, heating it up which could then lead to major climate change. Another is ______________ which causes acid rain. Acid rain can kill off _________ life, damaging delicate ecosystems. Pollution infra red sulphur dioxide plant gases carbon dioxide
Make a presentation answering these questions: What is global warming? What is acid rain? What causes of global warming? How is this different to climate change? What causes acid rain? What are the environmental effects of renewable energy resources. What are the environmental advantages and disadvantages to all the different energy resources you can think of? If you were in charge; explain how you would power the UK. The BIG Q: How should we power the UK?
