Energy resources bbc bitesize

There are different energy sources in the world energy resources bbc bitesize 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, energy resources bbc bitesize, which means they will eventually run out when all their reserves have been depleted used up.

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.

A lot of our energy comes from non-renewable sources such as coal, oil and gas. 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. Fossil fuels are burned by power stations to produce electricity as well as in things like cars, planes, and steam trains. But non-renewable resources generate harmful greenhouse gases that damage the habitats of animals and plants and contribute to global warming. And our increasing demand for energy means they won't last forever so we need to look for ways to make renewable and sustainable energy resources. For example, wind, solar and hydro energy. These are just some of the resources that are more friendly towards the environment. These renewable energy resources can quickly replenish themselves and can be used again and again. Non-renewable energy includes coal, gas and oil. Most cars, trains and planes use non-renewable energy. They all get the energy to move from burning fossil fuels to release the energy they contain. Once fossil fuels are burned they are gone - that's why they are non-renewable. Renewable energy includes solar, hydro and wind energy. When the wind moves the blades on a wind turbine this movement can be converted into electrical energy that we can use.

We use the sun as a source of energy in two main ways: solar cells and solar panels.

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.

In this guide. Find out more about tidal energy from The Regenerators. Renewable energy Wind energy Wave, tide and falling water energy resource Geothermal energy Solar heating Non-renewable energy resources Nuclear power Resources compared. Resources compared. Local habitats also affected. 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. Many inlets in the Highlands and Islands of Scotland contain these long strings of buoys to help boost local power levels. This is transferred to kinetic energy as the water rushes down through tubes inside the dam. The water runs through cracks in the rocks and energy is transferred by heating. Disadvantages Gases and smoke are released as the biomass fuel is burnt. No harmful gases are released. Sulphur dioxide and nitrogen oxides which cause acid rain. Jump to. In active volcanic areas, it can be used to heat water.

Energy is essential for everyone of us. Humans have advanced because we have learnt how to change energy from one form into another.

Solar cells are devices that convert light energy directly into electrical energy. Several wind turbines may be grouped together in windy locations to form wind farms. I think I might have to find an alternative energy. Energy is transferred from the sun by radiation. Renewable energy includes solar, hydro and wind energy. It can also warm water in solar panels. There are no fuel costs. More guides on this topic. Tidal Huge amounts of water move in and out of river mouths each day because of the tides. Advantages of using fossil fuels. Electrical power Electromagnetism Charge and current Series and parallel circuits Applications of series and parallel circuits. Energy resources can be divided into two categories: Renewable resources - energy resources that can be replenished.
