2 January 11, 2013 Title: Different energy resources Keywords 1.Renewable energy 2.Non-renewable energy 3.Sustainable energy Learning focus: 1.To explain the costs (disadvantages) and benefits (advantages) of using different types of energy sources. © DWIGHT SUTHERLAND 2012

3 Which picture is of renewable, non-renewable and sustainable energy? What is the difference between them? © DWIGHT SUTHERLAND 2012 A B C Renewable Non-renewable Sustainable

4 TASK: Explain the pros and the cons of obtaining and consuming each type of resource below. See next slide for some ideas. ResourceAdvantages (Benefits)Disadvantages (Costs) Crude oil is using fossil fuels in power station to create energy. It is an example of non- renewable resource. Bio-fuel is the use of crops like sugar cane to create energy. It is an example of sustainable resource. Solar energy is using the sun’s radiation to create energy. It is an example of renewable resource. © DWIGHT SUTHERLAND 2012

5 TASK: Explain the pros and the cons of obtaining and consuming each type of resource below. See next slide for some ideas. ResourceAdvantages (Benefits)Disadvantages (Costs) Crude oil is using fossil fuels in power station to create energy. It is an example of non- renewable resource. Bio-fuel is the use of crops like sugar cane to create energy. It is an example of sustainable resource. Solar energy is using the sun’s radiation to create energy. It is an example of renewable resource. © DWIGHT SUTHERLAND 2012 Some EXAMPLES of the impact of OBTAINING and CONSUMING different resources. Use these to help you with your cost-benefit analysis. It uses up good farm land It’s cheap to mine and use It can lead to spills in oceans etc. It doesn’t release any carbon emissions It allows poor farmers to earn money Using release carbon emissions It’s unlimited The technology to use isn’t fully developed as yet It will run out It is more sustainable It absorbs CO2 It can lead to food shortages It uses a lot of water It’s better for the environment It’s expensive to use A lot technology already use this

6 TASK: Explain the pros and the cons of obtaining and consuming each type of resource below. See next slide for some ideas. ResourceAdvantages (Benefits)Disadvantages (Costs) Crude oil is using fossil fuels in power station to create energy. It is an example of non- renewable resource. A lot of technology that we use already use oil for energy. Burning oil in power stations release carbon emissions which contribute to global warming. Bio-fuel is the use of crops like sugar cane to create energy. It is an example of sustainable resource. Provides poor farmers with an opportunity to increase their earnings. It can lead to food shortages as good farmland is being used to grow crops for energy rather than food. Solar energy is using the sun’s radiation to create energy. It is an example of renewable resource. Total renewable which means the supply is endless. The technology to use solar energy is still being develop and so is expensive. © DWIGHT SUTHERLAND 2012

7 Lesson summary TASK: Give an impact of using one energy source that is: Economic Environmental © DWIGHT SUTHERLAND 2012 Economic: Solar energy at the moment is quite expensive to set up. It will however create new energy jobs. Environmental: Solar energy is a clean energy; it does not release greenhouse gases. Solar panels can scar the landscapes; some people think they are unsightly.

8 TASK: Describe the global distribution of oil reserves. (3 marks) Model answer: Most oil reserves are in the Middle East. The Middle East has about 66% of oil reserves. Western Europe has little reserves of oil. It has just about 2% of oil reserves. Point about distribution Use of data as evidence Point about distribution

9 TASK: Which places in the world are ideal for solar energy? Give a reason for your answer. (3 marks) © DWIGHT SUTHERLAND 2012 Kilowatt energy per square metre per day Model answer: Areas in the tropics are ideal for solar energy. In the tropics places receive over 7 kilowatt of energy per square metre. Whereas near to the poles that drops to under 5 kilowatt of energy per square metre. Point about distribution Use of data as evidence. Point about distribution

10 TASK: Describe how biofuel demand will change in the next 8 years. (2 marks) © DWIGHT SUTHERLAND 2012 Model answer: Biofuel demand will increase in the next 8 years. For example demand in the North America will jump from 14 billion gallons to 34 billion gallons. An increase of 20 billion gallons. Point about change A more developed use of data Use of data as evidence

11 TASK: Give one fact about biofuel production today. (2 marks) © DWIGHT SUTHERLAND 2012

12 Useful websites ideas.com/.../pros_and_cons_of_solar_energy.html of-oil/ © DWIGHT SUTHERLAND 2012

13 Word association TASK: Give other words/phrases for renewable, non-renewable and sustainable energy. © DWIGHT SUTHERLAND 2012 Renewable energy Non- renewable energy Sustainable energy Energy that comes from a source that won’t run out. Energy that come from sources that won’t run out if they are manage responsibly. Energy from sources that will run out eventually.
