Renewable Energy Water Pumping Systems Handbook. Period of Performance: April 1-September 12, 2001

摘要

The world energy demand is increasing, and the search for alternative energy sources is a crucial issue to ensure future energy supplies. Developing countries currently account for 30% of global energy use, and approximately two billion people still live without electricity. As the world's population increases and the desire for basic services (such as electricity, water supplies, health services, and education) grows, supplying energy from the traditional grid system will be difficult because of infrastructure problems and the lack of economic resources in these developing countries. People not served by the power grid often rely heavily on fossil fuels. However, these fuels are often imported and price fluctuations in these fuels can disrupt the supply. Renewable energy technologies have great potential to fulfill the needs of people in these developing countries.
