Alternative
sources In contrast to the fossil fuel based generation of power, we have an increasing range of “alternative” energies from nuclear through to the so-called bio energy, renewable, sustainable and green energy. These terms can be misleading and sometimes even controversial. This section considers the alternatives in terms of the original energy source type which can be divided into nuclear, chemical, thermal, photo (light) and kinetic (motion) and potential (position). Notice many use the heat-kinetic energy route in order to exploit the classic turbine and generator combination.

The idea of alternative energy sources has raised an important further consideration – the reduction of energy consumption. The media and government have been accused of promoting the use of energy albeit from greener sources at the expense of focusing on energy reduction and this should not be overlooked in the overall developments following the Stern Review. It is also interesting that to date a key indicator of a developed nation has been its capacity to generate and perhaps more significantly to use energy. |
