Energy resources bbc bitesize

There are different energy sources in the world and the stores of energy associated with them can contain different amounts of energy resources bbc bitesize. 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.

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. Wind , the Sun and water are renewable energy sources that can be used to create electricity.

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. Renewable energy Wind energy Wave, tide and falling water energy resource Geothermal energy Solar heating Non-renewable energy resources Nuclear power Resources compared. Non-renewable energy resources. Fossil fuels. Fossil fuels include coal, oil and natural gas. Advantages of using fossil fuels. At the moment, fossil fuels are relatively cheap and easy to obtain.

It is taken in when chemical bonds break, and given out when chemical bonds are made.

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.

Energy is essential for everyone of us. Humans have advanced because we have learnt how to change energy from one form into another. Without being able to do that life would be very different. So, what is energy and how do we use it? All moving things have kinetic energy, even very large things like planets, and very small ones like atoms. The amount of kinetic energy an object has depends on:. It is the hot object, you are the cold object.

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.

Watch: Fossil fuels and renewable energy Activity: Quiz — Fossils fuels and renewable energy. And solar panels can generate electricity from the Sun. No fuel costs, but the equipment used is expensive to build. For example, wind, solar and hydro energy. Next page. Solar cells are devices that convert light energy directly into electrical energy. During nuclear or radioactive decay close nuclear decay The process in which unstable atomic nuclei break apart or change, releasing radiation and they do so. Hydroelectric power can be used to generate electricity. What are natural and agricultural resources? What do fossil fuels and renewable energy mean? How is electricity generated? Advantages and disadvantages of biomass Advantages Biomass is a renewable energy resource.

An explanation of the law of conservation of energy.

Tidal power. Power stations. Watch the video to understand more about geothermal energy. JavaScript is required to view this activity. Hydroelectric and tidal are reliable sources of power. Energy in the nuclear store is transferred to energy in the thermal store through nuclear reactions. Hydroelectric power stations use the energy inside moving water to convert to electrical energy. This video can not be played To play this video you need to enable JavaScript in your browser. Wave power generators use the kinetic energy in the waves to drive electricity generators inside them. The biomass is burnt and this can be used to turn water into steam.
