PV in LDC's photovoltaic power, developing countries

摘要

Two fifths of the world's population has no access to electricity. The true demand is not for electricity per se, but for services such as lighting, refrigeration, and better communications via radio, television and telephones. Many of these can be provided with a variety of power sources readily available in less developed countries (LDC). The ideal power source for a first-time use of electricity is photovoltaics. The author discusses the benefits of PV with regards to cost, maintenance and environmental factors.
