* The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat

Energy Management and Audit Report 1) Introduction For over the past few years‚ the planet Earth is being damaged by human activities. Buildings play a major role in that. They contribute to approximately 40% of the greenhouse gas emissions globally. Over the past 30 years‚ 10% of the ice burgs have been melted due to the rising temperature of Earth. The rise in temperature is caused by greenhouse gas. Therefore‚ green building is important today. Green building has both positive and negative

Wind Energy Wind energy is a free‚ renewable resource‚ so no matter how much is used today‚ there will still be the same supply in the future. Because the wind energy is also the source of the clean‚ and non- polluting‚ electricity. Wind energy is friendly to the surrounding environment‚ as no fossil fuels were to generate electricity from wind energy. Wind Energy is a viable industry that has become energy source. The energy generated from wind is clean and efficient. The wind energy industry

I will be informing you about nuclear energy. Prior to giving this information‚ let’s look at some history. Ancient Greek philosophers were the first to come up with the idea that matter is made up of invisible particles. The Greeks called these invisible particles "atoms"‚ which is Greek for invisible. Scientists studied this idea in the 18th and 19th centuries. After many experiments physicists found out that atoms contain a large amount of energy. Ernest Rutherford‚ a British scientist

Discuss and compare the relevance to the three energy systems for the sport of your choice‚ explain the details of each system? The body has only one unsuitable form of energy‚ this is known as ATP. ATP releases energy when broken down and is essential to the flow of energy to living cells. It can be re synthesized through a possible three energy systems; ATP-PC system‚ the glycolytic Lactic Acid system and the aerobic system.
