Space technology comes down to earth Available to Purchase

Space satellites have for years used solar cells for their source of electricity. However, the technology has been expensive and relatively inefficient in comparison with other energy sources for terrestrial applications. There is increasing pressure for the development of renewable energy sources in view of the pollution caused by fossil fuels and their increasing scarcity, and a growing number of organizations, particularly in the USA, are finding niches for economical applications. Further developments in sensors are also extending the possibilities. In the UK, work is not so far advanced, but there is a Government support programme and many organizations are working hard to bring in the solar energy revolution.
