Energy resources bbc bitesize

Some energy resources are renewable close renewable Energy resources that can be easily replenished or are effectively limitless. These energy resources bbc bitesize 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.

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. This may not always be the case. Much of our infrastructure close infrastructure The basic structures needed for an area to function, for example roads and communications.

Water power, ie tidal close tidal power Energy generated from the movement of tides.

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.

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.

Energy is essential for everyone of us.

Types of energy resource. Some people think that wind turbines spoil the landscape. These natural resources are formed from the remains of plants and animals that died millions of years ago. It is an unreliable energy resource. More guides on this topic. Hot water and steam may rise naturally to the surface. The fuel for nuclear power stations is relatively cheap, but the power stations themselves are expensive to build. Carbon capture and storage is a way to prevent carbon dioxide building up in the atmosphere. A non-renewable energy resource is one with a finite close finite Something that has a limited number of uses before it is depleted. Energy resources can be divided into two categories:. They operate almost continuously. Although growing biofuels can take up land that could be used for farming. They do not run out although we are using them. Disadvantages and advantages of nuclear fuel Disadvantages The nuclear fuel close nuclear fuel Radioactive material that is used in a nuclear reactor.
