One of the roles envisaged for highly efficient, small gas turbine power units is distributed generation. This refers to a power-supply system where small generating units are installed close to the source of demand.
Distributed generation is particularly attractive in situations where there are centres of electricity demand at the end of long transmission lines, distant from major central power stations. Installing a small generating unit close to such a demand centre both improves the stability of the overall transmission and distribution network and reduces the need to upgrade the transmission system.
There are a number of electricity generating technologies that are well suited to distributed generation. These include fuel cells, solar and wind power and small gas turbine power units.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
