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, energy resources bbc bitesize.

These natural resources are formed from the remains of plants and animals that died millions of years ago. They are used to power everything from planes to gas cookers. This adds to climate change by making the Earth warmer than it should be. Once fossil fuels are gone, they cannot be replaced. Renewable sources of energy are more sustainable, which means they continue to be used. Renewable energy is a natural source of energy that will never run out.

A non-renewable energy resource is one with a finite close finite Something that has a limited number of uses before it is depleted. For example, oil is a finite resource. It will eventually run out when all reserves have been used up. In this guide. Types of energy resource Comparing energy resources Comparing renewable sources of energy A national record Energy conservation and dissipation Energy change calculations Preventing unwanted energy transfers Energy efficiency. Types of energy resource. Renewable and non-renewable resources. Renewable resources are replenished either by:. Different energy resources. The table below shows the main features of the most common energy resources used today. Energy resource Energy store Renewable or non-renewable Uses Power output Impact on environment Fossil fuels oil, coal and natural gases Chemical Non-renewable Transport, heating, electricity generation High Releases CO 2 causes global warming Nuclear fuels Nuclear Non-renewable Electricity generation Very high Radioactive waste needs to be disposed of safely Biofuel Chemical Renewable Transport, heating, electricity generation Medium 'Carbon neutral' - little or no effect on the environment. Although growing biofuels can take up land that could be used for farming. Wind Kinetic Renewable Electricity generation Very low Takes up large areas that could be used for farming. Windmills change the landscape Hydroelectricity Gravitational potential Renewable Electricity generation Medium Local habitats are affected by the large areas that need to be flooded to build dams Geothermal Internal thermal Renewable Electricity generation, heating Medium Very low Tides Kinetic Renewable Electricity generation Potentially very high, but hard to harness Tidal barrages can block sewage which needs to go out to sea.

Energy resource Tides Energy store Kinetic Renewable or non-renewable Renewable Uses Electricity generation Power output Potentially very high, but hard to harness Impact on environment Tidal barrages can block sewage which needs to go out to sea, energy resources bbc bitesize. In volcanic areas, energy is transferred by heating. It is much higher than any of the fossil fuels.

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.

Nearly everything requires energy close energy The capacity for doing work. Systems that can store large amounts of energy are called energy resources close energy resource Useful supply or store of energy. The major energy resources available to produce electricity are fossil fuels close fossil fuel Natural, finite fuel formed from the remains of living organisms, eg oil, coal and natural gas. Ultimately, all the energy on Earth originally comes from the Sun but has been stored as different energy resources. However, producing and distributing electricity can cause damage to the environment. Releasing energy from some stores causes pollution and harmful waste products. Burning fossil fuels releases carbon dioxide, adding to the greenhouse effect, and sulphur dioxide which causes acid rain.

Wave power generators use the kinetic energy in the waves to drive electricity generators inside them. Watch the video to understand more about geothermal energy. So, how does it work? In this guide. What is renewable energy? 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. 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. Renewable energy Wind energy Wave, tide and falling water energy resource Geothermal energy Solar heating Non-renewable energy resources Nuclear power Resources compared. Hydropower - uses energy from moving water to drive turbines and generate electricity. It can generate electricity in solar cells. Renewable sources of energy are constantly being replaced and will never run out.

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.

The water high up behind the dam has a lot of energy in the gravitational potential energy store. The water is so hot that it produces steam which rises up through the pipes and is used to turn the blades of turbines. More on Energy sources and sustainability. Next up. In this short video, learn about the difference between renewable and non-renewable energy. Advantages and disadvantages of biomass Advantages Biomass is a renewable energy resource. Renewable sources of energy are more sustainable, which means they continue to be used. Nuclear fuel is a finite resource close finite resource Resource that is in limited supply. Not all energy resources are available everywhere and each one has its own advantages and disadvantages. In the Northern Hemisphere, solar cells or solar panels are positioned facing south on the roofs of buildings. What do geological resources mean?
