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. For example, nuclear fuel stores can contain very large amounts energy resources bbc bitesize 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.

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.

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. They were formed from the remains of living organisms plants and animals millions of years ago.

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. Solar power is an example of a renewable energy resource. This resource will eventually run out because we are using it. Fossil fuels and nuclear fuels are examples of non-renewable energy resources. Much of the energy that is transferred in our homes is supplied by electricity.

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.

Two large turbines are connected to a generator, which converts the movement of the tides into electrical energy. What do fossil fuels and renewable energy mean? In this guide. Jump to. Jump to. It is a rapidly evolving technology that involves separating carbon dioxide from waste gases. Working safely in the lab Find out how to spot risks, hazards and understand hazard symbols. It is important that it is stored correctly so that it is safe. Geothermal energy is limited to only a few places around the world that are volcanically active. Related links. These can cause smog and result in breathing difficulties. Turbines take up large areas that could be used for farming. Advantages Unlike fossil fuels close fossil fuel Natural, finite fuel formed from the remains of living organisms, eg coal, oil and natural gas. Although a lot of research has been done on how to make nuclear power stations safe, if an accident occurs radioactive material may be released into the environment. Waves are not a reliable source of power.

Fossil fuels and nuclear fuels are examples of non-renewable energy resources. The hot water and steam can also be used for heating buildings directly. Oil is a fossil fuel used in vehicles and machines. Nuclear power stations generate electricity using nuclear fuels, such as uranium and plutonium. It returns to the surface as hot water and steam. The water runs through cracks in the rocks and energy is transferred by heating. These resources will not run out by being used. Solar power. Electricity generation Renewable energy resources Pros and cons of non-renewable energy resources Pros and cons of renewable energy resources Distribution and use of electricity. Hydro-electric power schemes use water stored in dams. Although a lot of research has been done on how to make nuclear power stations safe, if an accident occurs radioactive material may be released into the environment. What are batteries and energy stores? The table below shows the main features of the most common energy sources used today. Electrical power Electromagnetism Charge and current Series and parallel circuits Applications of series and parallel circuits. 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.
