Energy resources bbc bitesize

Some energy resources are renewable close renewable Energy resources that can be easily replenished or are effectively limitless. These resources will not run out by being used.

There are different energy sources in the world and the stores of energy associated with them can contain different amounts of energy. For example, nuclear fuel stores can contain very large amounts of energy, while hydroelectric close hydroelectricity Electricity that is generated by the movement of water. Some energy sources are renewable, which means they can be replenished and will not run out. Other energy sources are non-renewable, which means they will eventually run out when all their reserves have been depleted used up. In this guide.

There are many different types of renewable energy resources. Renewable sources of energy are constantly being replaced and will never run out. The most important in Scotland are: wind power, wave power, hydroelectric power, solar power and in the future, tidal power. Wind turbines have huge blades mounted on a tall tower. The blades are connected to a generator. As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator. Several wind turbines may be grouped together in windy locations to form wind farms. Waves in the sea make the water rise and fall. Wave power generators use the kinetic energy in the waves to drive electricity generators inside them. They are buoys that are strung together in long lines so that large amounts of electricity can be generated at the same time.

And solar panels can generate electricity from the Sun. Nuclear fuel close nuclear fuel Radioactive material that is used in a nuclear reactor. Video Transcript Video Transcript A lot of our energy comes from non-renewable sources such as coal, energy resources bbc bitesize, oil and gas.

They were formed from the remains of living organisms plants and animals millions of years ago. They have chemical energy close chemical energy A type of stored energy. It is taken in when chemical bonds break, and given out when chemical bonds are made. About three-quarters of the electricity generated in the UK comes from power stations fuelled by fossil fuels. This diagram shows an energy transfer diagram for the generation of electricity from a fossil fuel such as coal. The carbon dioxide is then stored underground, for example in old oil or gas fields such as those found under the North Sea. In this guide.

Solar energy - solar panels collect energy from the Sun to create electricity. In this guide. Video Transcript Video Transcript A lot of our energy comes from non-renewable sources such as coal, oil and gas. Energy resource Wind Energy store Kinetic Renewable or non-renewable Renewable Uses Electricity generation Power output Very low Impact on environment Turbines take up large areas that could be used for farming. The biomass is burnt and this can be used to turn water into steam. This is usually uranium or plutonium. These resources are made up from the remains of ancient animals and plants that develop over millions and millions of years, deep beneath the ground into what we call fossil fuels. More on Energy sources and sustainability. Energy resources are used to generate electricity. The water from this hot spring is being warmed by rocks heated by volcanic activity deep under the ground. Energy resource Hydroelectricity Energy store Gravitational potential Renewable or non-renewable Renewable Uses Electricity generation Power output Medium Impact on environment Local habitats are affected by the large areas that need to be flooded to build dams. Wind turbines can make a lot of noise and some people do not like to live near them because of this. Find out more about tidal energy from The Regenerators.

In , around a third of the UK's electricity was generated by renewable energy close renewable energy Power that is generated using natural resources that will not run out, eg wind and wave power. They are a non-finite resource close non-finite resource A renewable energy that harnesses the Earth's natural resources. Examples include:.

The best bit is that after the steam has powered the turbines it can be cooled until it condenses back into water and then pumped back down to be reused and heated again. Watch: Fossil fuels and renewable energy. It is much higher than any of the fossil fuels. Wind is caused by the movement of air. The barrage contains electricity generators close generator Device that is made to rotate by mechanical working. Solar power. Wind energy - wind turns turbines to create electricity. Energy resources are used to generate electricity. What is sustainability? Renewable energy - wind. In this guide. Video Types of energy Test your knowledge Activity Quiz. In some volcanic regions, like Iceland, geothermal energy is so close to the surface and easy to tap into that the heat is used for other things other than generating electricity.
