Renewable energy technologies for developing countries phần 2

Khoảng cách giữa WordPress và Drupal ngày càng tăng. Khoảng cách giữa Drupal và Joomla! thu hẹp (một ít). Compete41 cung cấp dịch vụ phân tích trang web. Một nhìn vào số liệu thống kê cho 3 trang web hàng đầu của dự án của chúng tôi cho thấy một số chuyển động thú vị. | electric demand can be attributed to the actual as opposed to the assumed prices. This is the cost-effective energy conservation which represents only a part of the eventual adjustment one can expect in the gradual replacement of energy-consuming equipment. Fig. 5 6 clearly indicate increase of energy use and consumption as per growth of economy from 1970-2000 with projections upto 2020 the highest energy-consumption projected will be in Developing Asia due to highest growth in economy. The rates of economic development are amongst the most important determinants of energy-demand in the long term. The World Energy Consumption WEC study predicts an increase in global energy-need in the range of 1.5 to 3 times by 2050 and 2 to 5 times by 2100. Taken together energy requirements are envisaged to increase at lower rates than economic growth. This means that energyintensity is presumed to decline across all scenarios by 2100 it will fall between 80 and 20 per cent of the 1990 levels. This translates into annual declines of about 0.8 and more than 1.5 with a median of about 1 percent. Thus the lowest future energy-intensity improvements of 0.8 a year are in line with the historical experience of industrialized countries. To sum up technology is the key indicator of economic development and is essential for raising the standard of living but it also should be environment friendly. Technology development and its application needs RD E which in turn needs investments. The energy infra-structure grow consistent by part of it will be shared by renewables specially new emerging RETs such as Hydrogen and Fuel Cell technology. Improvement in technology will gradually shift us from the fossil fuels to renewable energies around 10 to 15 by 2020 and hopefully 30 by the year 2050. Global Energy-Economy - 50 energy is consumed by 16 population - 1.6 billion people have no access to commercial energy - 55 increase in global energy-demand between 2000 and 2020 - Share of Developing .
