How Npower /RWE Contributes To The Economy
In the energy industry, energy and gas suppliers provide essential power supplies for homes and businesses. Companies like Npower seek to try keep energy prices low while functioning for 365 days a year.
RWE Npower is an integrated energy company and is one of the largest suppliers of gas and electricity in the UK.
RWE npower not only provides and supplies to the national grid (electricity) and to the national transmission system (gas), it also provides a huge economic contribution. This is illustrated by the figures for turnover, capital employed and employment.
As one of the UK's leading companies RWE npower contributes to the economy by:
•providing exciting jobs with prospects
•selling energy to households and businesses, enabling a better standard of living
•investing in huge capital projects such as the building of power stations (including the development of alternative power supplies such as wind farms and biomass plants)] Describe How Waste Products Are Produced Waste is created when fossil fuel-fired power stations generate electricity. As with any kind of industrial waste, its impact needs to be minimised and managed. The most significant form of waste produced by fossil fuel-fired power stations is carbon dioxide (CO2), which is a major contributor to global climate change.
Although power plants are regulated by federal and state laws to protect human health and the environment, there is a wide variation of environmental impacts associated with power generation technologies.
The purpose of the following section is to give a better idea of the specific air, water, and solid waste releases associated with oil-fired electricity generation. Air Emissions
Burning oil at power plants produces nitrogen oxides, sulfur dioxide, carbon dioxide, >methane, and mercury compounds. The amount of sulfur dioxide and mercury compounds can vary greatly depending on the sulfur and mercury content of the oil that is burned.
In addition, oil wells and oil collection equipment are a source of emissions of methane, a potent greenhouse gas. The large engines that are used in the oil drilling, production, and transportation processes burn natural gas or diesel that also produce emissions. Water Discharges
Refineries release treated wastewater, which can contain pollutants, into streams and other bodies of water. Likewise, power plants release waste water, which contains pollutants and is generally hotter than the water in nearby lakes and streams, often harming fish and plants. This discharge usually requires a permit and is monitored. Solid Waste Generation
Oil refining produces wastewater sludge and other solid waste that can contain high levels of metals and toxic compounds and that may require special handling, treatment, and disposal. Also, when oil is burned at power plants, residues that are not completely burned can accumulate, forming another source of solid waste that must be disposed. Land Resource Use
The construction of large oil-fired power plants can destroy habitats for animals and plants. Waste products from refining and from power plants (such as wastewater sludge and residues) can cause land contamination if not properly disposed. In addition, when oil spills occur on land, soils are degraded. Explain How People Travel To The Site – Main Road Routes
