Abstract
Thermoelectric and solar-energy technologies are the focus of significant research, and can make a major contribution to the need to find alternative methods of power generation, heating and cooling. Solar-energy, or photovoltaic technology, is established as an alternative energy source, and in common with wind, biomass, wave and geothermal, is considered a renewable energy source. Thermoelectric technology is often overlooked, but can be used in applications where other technologies could not be used, or in combination with other renewable technologies. Contemporary problems surrounding climate change will act as a stimulus for the development of thermoelectrics, and the technology is successful in cooling, refrigeration and space-craft power, with potential for growth in power generation applications.
