1 Why might our electricity become more expensive in the the next couple of months?

2 Renewable resources; By the end of the lesson you will; 1) Be able to describe and explain the key features of tidal energy 2) Have evaluated which method would be best for the UK and a range of countries around the world 3) Have explained smaller scale alternatives to be used in the the home

3 Homework You need to research 3 different methods of producing renewable energies in the UK. You should explain; 1) Where are they based? 2) How successful have they been? 3) What issues have there been? 4) Are they a long term solution Off shore wind; www.londonarray.com/about www.reuk.co.uk www.bwea.com Wave; www.wavegen.com Tidal www.reuk.co.uk/severn- Barrage-tidal-Power.htm www.foe.co.uk

4 Wave Energy Task 1. Watch the following animationfollowing animation 2. Describe how wave energy is generated What is it? How does it generate electricity? Why is it a good method? Why is it not a good method? Where is it best suited for?

5 Renewable resources; By the end of the lesson you will; 1) Be able to describe and explain the key features of tidal energy 2) Have evaluated which method would be best for the UK and a range of countries around the world 3) Have explained smaller scale alternatives to be used in the the home

6 Renewable energy relative costs; Task Read through the following article 1. Which are the cheapest of the Stock fuels? 2. Which are the cheapest of the flow fuels? 3. How much different is there in the costs of stock and flow energies? 4. Why have these changes occurred? 1.The levelized cost of electricity (LCOE) from wind and solar sources in America has fallen by more than 50% over the past four years 2.Lazard estimates that utility-scale solar PV is now a competitive source of peak energy compared to fossil fuel power in many parts of the world without subsidies 3.solar PV and wind energy both fall within the range of $68-$104 per MWh, making them extremely [coal ($65-$145 per MWh), nuclear ($86-$122 per MWh), and integrated gasification combined cycle ($95-$154 per MWh).] 4.With US government subsidies the energy is even cheaper. wind ($23-$85 per MWh) and thin-film utility scale solar PV ($51-$78 per MWh) especially competitive. 5.utility-scale solar PV leads the LCOE charge, rooftop solar PV remains expensive by comparison

7 Evaluating renewable; Task 1. One representative is going to work on each sheet 2. You need to add in as much information as possible to answer the following questions 3. Add in figures where ever possible 4. Add in examples from your own research Why are renewable energies great for the UK? Why are renewable energies not great for the UK? Task 2 Overall do you think they are a good or bad thing for the UK?

8 Which is best / Worst? Task You need to order the Energies Be ready to explain your answers 1. Which is the best? 2. Which is the worst? Energy Type Biomass Wind Tidal Solar Wave Coal Oil Gas Nuclear Task 2 For each of the different countries, order the energy types from best to worst UK Iran Singapore Australia Ukraine

9 Renewable resources; By the end of the lesson you will; 1) Be able to describe and explain the key features of tidal energy 2) Have evaluated which method would be best for the UK and a range of countries around the world 3) Have explained smaller scale alternatives to be used in the the home

10 Small Scale energy use; Task 1. What can be done in the home to reduce the energy use? 2. How will these help? Extension; Which of these methods do you think would be used by your family?

11 BedZed Community Task 1. Watch the following video clipvideo clip 2. How does this community reduce their impact on the world? 3. How is this a sustainable development? How do they use resources?What is done with their waste?How do they reduce air pollution? How do they reduce reliance on Fossil Fuels? What methods are used to save electricity usage? What travel options are there? How do they promote the economy?How does it enhance the natural environment? How is this a sustainable development?

12 Renewable resources; By the end of the lesson you will; 1) Be able to describe and explain the key features of tidal energy 2) Have evaluated which method would be best for the UK and a range of countries around the world 3) Have explained smaller scale alternatives to be used in the the home

13 What have you learnt? Which is the best renewable method for the UK? Which is the best fuel for the UK? What considerations should be made when considering a renewable future? What considerations should be made when considering stock fuels in the future? How has BedZed reduced its reliance on Fossil fuels?
