Our Earth is made up of matter that is everything that has mass and occupies space. The formation of matter is because of energy and one of the examples of energy is the renewable energy. Renewable energy is energy that sources from natural resources that is constantly renewed on a human timescale and cannot be exhausted. Renewable energy is classified into five components which are hydro, wind, biomass, solar and geothermal energy (refer to Figure 1 in Appendix 1). The first type of renewable energy is the hydro energy.
Oil, one of the fossil fuels, is used in producing gasoline, jet fuel and diesel fuel. Oil is also used in producing electricity. Coal, another fossil fuel, is used in producing electricity as well. In addition to producing electricity, coal is used in producing steel and making cement. Natural gas is used in cooling homes and cooking.
The environmental impact of the coal industry includes sally such as land use, waste management, water and air pollution, caused by the drawing coal from mines, processing and the use of its products. In addition to environmental hazard, coal burning produces hundreds of millions of tons of solid waste products perennially. Renewable energy is energy source that can be renewed naturally, like deriving power from solar, wind, geothermal. Energy produced from the refining of biomass is also classified as renewable. Coal, oil natural gases are the finite sources available for us.
The Company's NACoal main point of business is the coal used in power generation and offer mining services for other natural resources companies. The Coal for NACoal is surface mined from their mines in North Dakota, Texas, Mississippi, Louisiana and the Navajo Nation in New Mexico. As stated in NACCO Industries Inc Profile NACoal's operating coal mining affiliates include Bisti Fuels Company, LLC (Bisti), Caddo Creek Resources Company, LLC (Caddo Creek), Camino Real Fuels, LLC (Camino Real), The Coteau Properties Company (Coteau), Coyote Creek Mining Company, LLC (Coyote Creek), Demery Resources Company, LLC (Demery), The Falkirk Mining Company (Falkirk), Liberty Fuels Company, LLC (Liberty), Mississippi Lignite Mining Company (MLMC) and The Sabine Mining Company (Sabine). Coteau, Coyote, Falkirk, Liberty, MLMC and Sabine supply lignite coal for power generation.
Some natural resources, such as fossil fuels and natural gas are running dangerously low and could be used up in less than 40 years from now. (Howstuffswork.com) Time is running out to find a more cleaner, and reusable energy source. However, what people don’t know is, we may already have that answer lying beneath our feet, geothermal energy. The prefix "geo-" means earth and the root "thermal" means heat. Geothermal power plants use the heat radiating from the center of the Earth to generate electricity and, in Iceland, to heat the entire cities.
Theoretically speaking, as long as the turbines continue to spin and the earth does not cool down this process can run forever (refer to figure 2). Cons Very site specific Geothermal power plants drill deep into the earth 's crust, the closer the bottom of such tunnels are to the mantle the hotter it gets. In some places the earth 's crust is on 5km thick while in other places the crust is up to 70 km deep. Only very few places have a really thin crust underneath, so scientist take image of the ground beneath and only the best (thinnest crust) areas will be drilled into. Refer to figure 1 to see which parts of the world are able to proficiently use geothermal power plants.
Hydroelectric energy is becoming a common source of electricity production in the 21st century. Most dams that are being built have infrastructure that allows them to capture the energy from the water. The kinetic energy of moving water is then used by hydropower plants to give mechanical energy to turbines which in turn convert it to electrical energy through generators. 4. Geothermal Energy Within the Earth, there is a great deal of energy trapped inside molten magma.
ABSTRACT Coal is an old technique and efficiency and emissions through technologies clean coal in small modern coal power plants taken. The energy of coal still generates energy for millions of people in coal plants. Coal, like all other energy sources, has a number of effects on the environment; both coal mining and coal use. The use of all technologies for electricity production will inevitably lead to some degree of pollution. A number of advanced coal combustion technologies have been developed to improve the efficiency of power generation from coal.
This cycle is critical to ecosystems as it is part of the food chain. All living things are made of carbon (compounds like proteins, fats, nucleic acids, and carbohydrates) and it is recycled in various ways. The compound formula for the carbon cycle is C6HI206+602→ 6H2=6C02+energy. There are 5 parts to the carbon cycle. There 's combustion which is when carbon is released into the atmosphere when burning fossil fuels-- heating homes, driving cars.photosynthesis is when carbon is absorbed by producers/ autotrophs- plants that make their own food through photosynthesis.
Since the industrial revolution, crude oil has been the major source of energy which powers daily life. Crude oil otherwise known as fossil fuel, consists of a complex mixture of different molecular weight hydrocarbons and organic compounds that are explore from the earth. Crude oil is heterogeneous in nature with the main constituents being aromatic and aliphatic hydrocarbons, asphaltines and resins (Al-Gamdi, 2011). At high temperature and pressure, crude oil is formed through the pyrolysis of the hydrocarbons through different types of reactions most of which are exothermic reaction (Arun et al. 2011).
