Реферат Renewable resources in Ukraine





for Kennetec wind turbines operating in the USA, which is partly financing the involvement of Kennetec. The price for each turbine was initially $ 23,000 US, well below world market price. Now the price is $ 50,000 US, which is close to world market price. The price increase is due to higher overhead costs of the companies because of a decreased of other production. Increased competition and restructuring are expected to bring prices down again. The wind-electricity is produced at 2.0 US cents/kWh and sold for 2.4 US cents/kWh to the power company. The consumer price is 3.1 US cents/kWh. In 1994, the government of Ukraine created a fund for construction of wind turbines. The initial goal was to finance 100 MW of wind turbines. Since then, the decision has been made to support additional development using part of the national tariff on electricity. Thus, 0.5% of consumer electricity payments, equal to $ 15 million US annually, will be allocated to the fund. The official Ukrainian energy plan includes the installation of 2000 MW wind turbines by the year 2010. This will cover 10% of the Ukrainian demand for electricity.There is a great potential for wind energy in Ukraine. Especially, Crimean coasts make Ukraine the second country in the world (after Norway) in shallow water areas that are suitable for large wind farms. At present about forty industrial enterprises, previously under jurisdiction of the military-industrial establishment, are engaged in the production process of licensed units for the turbines USW 56-100. These wind turbines are assembled at the Industrial Complex "Yuzhny Machine-Building Plant "(PO" Yuzny Mashinostroitel'nyi Zavod ") in Dnipropetrovsk. The first three modern windmills in Ukraine were installed in May 1993 in the Crimea within Donuzlav Bay. In 1994, one GWh of electric energy was generated. br/>

Solar energy is clean energy


Even when the emissions related to solar cell manufacturing are counted, photovoltaic generation produces less than 15% of the carbon dioxide from a conventional coal-fired power plant. Using solar energy to replace the use of traditional fossil fuel energy sources can prevent the release of pollutants into the atmosphere. Using solar energy to supply a million homes with energy would reduce CO2 emissions by 4.3 million tons per year, the equivalent of removing 850,000 cars from the road.

Solar energy uses fewer natural resources than conventional energy sources. Using energy from sunlight can replace the use of stored energy in natural resources such as petroleum, natural gas, and coal. Fossil fuel extraction can use drilling and mining techniques that leave land undesirable for other uses after the energy source has been removed. Photovoltaic (PV) panels can be integrated into building surfaces for the production of power, eliminating additional land use. For example, the 100,000 square foot roof of a typical discount retailer could produce more than a megawatt of solar electricity.

Solar energy systems need less space to produce a megawatt of electricity than coal-fired power when the land devoted to mining is factored in. No land is required when solar systems are integrated into buildings.

Solar energy is a renewable resource. Some scientists and industry experts estimate that renewable energy sources, such as solar, can supply up to half of the world's energy demand in the next 50 years, even as energy needs continue to grow. To avoid an energy crisis, we need to begin shifting our energy reliance away from our finite supply of fossil fuels and towards renewable energy sources such as solar.

Enough sunlight reaches the earth's surface every year to produce approximately 1,000 times the amount of energy produced by burning all fossil fuels mined and extracted during the same time period. If this energy is effectively captured, it could meet human energy needs indefinitely.

In summary, solar energy is a smart energy choice.

Energy Use


At 6.4 quadrillion Btu (quads) in 1999, Ukraine's energy consumption accounts for 1.7% of the world's total. In 1998, the country's vast industrial sector accounted for a disproportionate 61% share of the country's total, with residential standing at 16%, transportation at 14%, and commercial 9%. In 1999, natural gas consumption represented the largest percentage of energy consumption at 44%, with coal and oil at 30% and 11.8%, respectively. Looking at recent trends, Ukraine has followed a continual pattern of reduced energy consumption. Since 1992, Ukraine energy consumption has dropped from 8.86 quads to 6.43 quads in 1999 - a 27% drop. This figure is even more impressive when compared to Ukraine's neighbours that are also in transition to market economies. Only Russia, which saw a 25% decrease (from 34.9 quads to 26.0 quads), experienced a similar pattern. Unfortunately,...
