Exploring Renewable and Non-Renewable Energy Sources
Understanding the difference between renewable and non-renewable energy sources such as fossil fuels and renewable sources like biomass, hydro-electric, solar, wave, and wind energy. Learn how electricity is generated, the impact on the environment, and the benefits of using renewable energy. Discover the transformation from traditional power stations to sustainable wind farms and the utilization of wind power for generating electricity.

L.O. To learn about the difference between renewable and non-renewable energy. S.C. I will be able to name at least 3 types of renewable energy.
Non- renewable energy. Fossil fuels (coal, natural gas and oil) are burned in power stations to produce electricity. When this happens, carbon dioxide, sulphur dioxide, water vapour and other gases are produced. These gases are the causes of several environmental problems.
Research Task Use Google to answer the following questions 1) ________________________________________________ 2) Where does petrol and diesel come from? ________________________________________________ 3) Where do fossil fuels come from? ________________________________________________ 4) What do scientists believe is causing pollution and climate change? ________________________________________________ 5) How do we get coal? ________________________________________________ 6) How do we get electricity from oil and gas? ________________________________________________ 7) Where is electricity made? ____________________________________________ Where does most of the UK s energy come from?
The way forward Biomass Hydro-electric Solar Wave Wind Renewable sources of energy will never run out and can be used again and again.
The wind can make things move. This power is called wind energy. A long time ago, people used windmills to make flour. Today, big wind turbines work in the same way, but they use wind to generate electricity.
Wind power - The wind spins the rotor blades. - When the rotor blades spin, they turn a machine inside the top of the turbine, called a generator. - As the generator spins, it makes electricity. - The electricity runs along power cables to homes and other buildings.
Hydro electric energy - This picture shows a reservoir and a dam. A dam is a huge concrete wall that holds the water back. - There are gates in the dam to let the water through. - When the gates are open, the water rushes through. - The water turns machines that make electricity.
Solar power. - This house has solar panels on the roof. - When the sun's light shines on the panels, they turn the light into electricity. - The electricity runs along cables and we can use it to power lights, computers and TVs.
Biomass energy - The farmer planted the trees in this picture to make fuel. - First the farmer cuts the young trees to make small wood chips. We can burn the dry wood chips to make steam, which can be used to make electricity. - As soon as the trees are cut down, the farmer plants new ones, so the fuel never runs out.
This machine can use the power of the tides to make electricity. When the tide goes in or out, the water pushes the blades round and round. When the blades turn, they work a generator, which makes electricity.
Research Task Use Google to answer the following questions 1) ________________________________________________ 2) What is good about renewable energy? ________________________________________________ 3) Where are wind farms being built? ________________________________________________ 4) What does hydroelectric energy mean? ________________________________________________ 5) What is biomass? ________________________________________________ 6) What does solar energy mean? ________________________________________________ 7) What can hydrogen fuel cells be used to power? ________________________________________________ 8) Where does geothermal energy come from? ________________________________________________ Name 3 types of renewable energy.
Electricity is generated in the same way by both renewable and non-renewable sources of energy. They all contain a turbine which, when turned, turns a generator and generates electricity. Watch video .BBC primary focus green power.
