Wind Power The Benefits of Wind Power: The Problems with Wind Power: FACT! In Denmark, 15,000 people are employed in the winder energy industry and 13% of its household electricity is produced by wind The Benefits of Wind Power: Wins is free and wind farms need no fuel. Wind powers produces not pollution or carbon emissions. The UK is the windiest country in Europe Wind power could supply 10% of the world’s electricity in 20 years time. “Wind power is cheap, sustainable and inexpensive.” Nick Goodall (Chief Executive of the British Wind Energy Association The Problems with Wind Power: Some think big wind turbines are an eyesore, especially if they are on land. It is not always reliable – what happens if there is no wind? Suitable sites for wind farms are often near the coast, where land can be expensive. Even if wind power could supply 10% of the world’s electricity in 20 years, we still need other forms of energy

Fossil Fuels Fossil Fuels mean coal, gas and oil) The Benefits of Energy from Fossil Fuels: It is relatively cheap to create. Transporting oil and gas to power stations is relatively easy. Gas produces much less pollution than coal or oil. Very large amounts of electricity can be produced from one power station. A third of the UK’s electricity comes from coal. New technologies are reducing the pollution it creates. Over 90% of Britain’s energy comes from fossil fuels at the moment. The Problems of Energy from Coal: It creates of lot of carbon emissions (pollution), contributing to global warming and an unhealthy atmosphere. Coal produces 2-3 times more C02 than gas. The coal industry receives a lot of money from the government to keep it going – why is this money not invested in renewable energy? Mining coal and gas and oil pipelines can damage the environment and create a major eyesore

Nuclear Power The Benefits of Nuclear Power: It produces no harmful carbon emissions (pollution) like coal does. It costs about the same as coal, so it’s not expensive to make. It is a reliable, sustainable power source because it is not dependant on the weather or fossil fuels. It only produces s small amount of waste The Problems with Nuclear Power: It is potentially very dangerous (see example left) The waste it produces is also very dangerous. 
It must be sealed up and buried for many thousands of years to allow the radioactivity to die away. For all that time it must be kept safe from earthquakes, flooding, terrorists and everything else. This is difficult. It is expensive to build and to deal with the waste. It is a potential terrorist target – one study estimated that if a plane flew into a nuclear plant it could cause 30,000 deaths in 2 days on the local area Would you want to live near one? In 1986 an accident at a nuclear power plant in Ukraine (near Russia) affected millions of people. Many died. Many children got cancer from the radiation. These children are receiving treatment to cure them. The treatment has caused their hair to fall out. However, events like this are very rare.

Tidal Power The Problems of Tidal Power: At the moment it has not been widely tested It only supplies 1% of electricity in the UK at the moment – even if we develop it we will need other sources of energy A barrage across an estuary is very expensive to build, and affects a very wide area - the environment is changed for many miles upstream and downstream, affecting birds and fish. Tidal power only provides power for around 10 hours each day, when the tide is actually moving in or out. There are few suitable sites for tidal barrages. This is a picture of wave turbines which are set into the ocean floor. The waves turn the blades generating electricity which is sent to land underground. FACT! Tidal and wave power has the potential to produce 20% of the world’s electricity The Benefits of Tidal Power: Once you’ve built it, tidal power is free. It creates no pollution It is safe It is guaranteed – there will always be the tide

MAKING A DIFFERENCE IN MY HOME The Problem: A quarter of the Canada’s carbon emissions come from our homes. This is mostly because we waste so much electricity by… using old light bulbs, charging our phones too long….. Also, a lot of heat escapes from our homes, usually through the loft / roof.

MAKING A DIFFERENCE IN MY HOME The Solution: Three ways to stop wasting electricity are: use energy saving light bulbs charge our phone for just an hour and………………………………………………….. One of the best ways to reduce our energy use is to insulate our lofts.

MAKING A DIFFERENCE IN MY COUNTRY The Problem: Over 90% of electricity in our country comes from fossil fuels. Some of the problems with fossil fuels are that: They create a lot of carbon emissions They will eventually run out

MAKING A DIFFERENCE IN MY COUNTRY The Solution: We need to use more forms of energy that will not run out, and do not produce carbon emissions, such as wind power, solar power etc. We need to put limits on the amount of carbon emissions a power station is allowed to produce.

MAKING A DIFFERENCE IN OUR WORLD The Problem: Many countries are suffering from the effects of climate change. It’s usually the poorest countries that suffer the most, but it’s the richest countries that produce the most pollution (carbon emissions). FACT: The United States has 5% of the world’s population, but produces 25% of the world’s pollution.
