their environment. The Industrial Revolution dramatically changed every aspect of human life and lifestyles. In this era‚ machinery replaced manual labor and fossil fuels replaced wind‚ water‚ and wood. The exploitation of natural resources such as coal and iron ore was also necessary to fuel steam engines for trains and boats in America during the 1800’s. By the early 1900’s‚ a huge increase in global factories and commercial sectors saw rapid growth economically. The start of car production was

Being carbon-based‚ natural gas‚ oil and coal store carbon as potential energy and release it when burned. The Intergovernmental Panel on Climate Change states that carbon and other greenhouse gas emissions are a major culprit in climate change. Effects 3.

Not only are nuclear plants dangerous but coal power plants have also caused several deaths in the past few years from accidents‚ and the byproducts of coal power plants have been linked to acid rain. To improve the safety concerns of nuclear power plants we can develope a more advanced technology and design to help with this concern. Turning the

Chapter 8 Renewable Energy Part 1 Where do we get energy from ? PLANETARY ENERGY RESOURCES Non-Renewable Sources • Fossil-fuel sources of energy: • Coal • Gas • Oil • During earlier periods of the Earth’s history‚ fossilization of biological material created the deposits of coal‚ oil and gas‚ of which at least 1023 Joule is presently believed to be recoverable in a form suitable for fuel uses (Sorensen‚ 2011). • Nuclear energy may be released in large quantities from nuclear reactions (Sorensen

in homes‚ industries and also in the transportation. The huge desire of wood for the iron industry resulted in the shortage of wood which led to stagnate the iron industry. Britain began to look after the reserves of coal as an alternative source of energy. While producing the coals‚ mines were dug deeper and at the same time‚ the water level filled the area. To pump the water‚ mechanical pumps were installed‚ but the process was troublesome and also expensive. To overcome this difficulty‚ Savery

not taken seriously. “Coal‚ oil and natural gas are called fossil fuels because of the way that they were formed‚ the end products of photosynthesis that formed millions of years ago in large deposits of carbon compounds” (Berg & Hager‚ 2007 p. 7 & 105). Fossil fuels are also referred to as nonrenewable energy sources because natural processes do not replenish these sources within a reasonable period of time in which to be reused‚ they take millions of years to form.

sector of Wyoming’s economy. Coal : Wyoming is the nation’s leading coal producer. The nation’s top 10 coal mines are situated here and has the world’s largest surface coal mining operations near Gillette. In 1868 the Union pacific railroad opened the first coal mine in carbon county. It was named Carbon county because extensive coal deposits were found there. Most of Wyoming’s coal mines are found in the powder river basin. There has been some disasters in the coal mines too. Oil and Natural

boilers are designed to use the chemical energy in fuel to raise the energy content of water so that it can be used for heating and power applications. Many fossil and non-fossil fuels are fired in boilers‚ but the most common types of fuel include coal‚ oil and natural gas. During the combustion process‚ oxygen reacts with carbon‚ hydrogen and other elements in the fuel to produce a flame and hot combustion gases. As these gases are drawn through the boiler‚ they cool as heat is transferred to water
