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 energy resources bbc bitesize. But non-renewable resources generate harmful greenhouse gases that damage the habitats of animals and plants and contribute to global warming.

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.

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. Energy requirements Energy consumption Sources of energy. Sources of energy. The table below shows the main features of the most common energy sources 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 , which contributes to global warming. Nuclear fuels Nuclear Non-renewable Electricity generation Very high Produces radioactive waste which needs to be disposed of safely.

What are batteries and energy stores? Geothermal energy plants use this hot water to generate electricity. What is renewable and non-renewable energy?

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.

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:.

Geothermal resources come from either volcanic areas or hot rocks. Video Transcript Video Transcript A lot of our energy comes from non-renewable sources such as coal, oil and gas. Renewable resources - energy resources that can be replenished. Activity: Quiz — Fossils fuels and renewable energy. Hot water spewing out of a geothermal vent. The turbines drives electrical generators close generator Device that is made to rotate by mechanical working. The water rushing through the propeller generates electricity. Energy requirements Energy consumption Sources of energy. Water is held behind a dam built across a river. They have chemical energy close chemical energy A type of stored energy. Hydro-electric power schemes use water stored in dams.

An explanation of the law of conservation of energy. An investigation into energy efficiency in a leisure centre. How energy is transferred from one place or object to another.

It stores it in the soil, plants or trees. Nuclear energy is also a low carbon fuel but is not renewable because it uses up radioactive fuel. Renewable energy is a natural source of energy that will never run out. Energy resources can be divided into two categories:. Play fun and educational primary games in science, maths, English, history, geography, art and design, computing and modern languages. 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. These can cause smog and result in breathing difficulties. Unlike fossil fuels close fossil fuel Natural, finite fuel formed from the remains of living organisms, eg coal, oil and natural gas. Solar energy resource is an example of a renewable close renewable Energy resources that can be easily replenished or are effectively limitless. Disadvantages It is an unreliable energy resource. It is much higher than any of the fossil fuels.
