endangered, definition of

Sustainable energy refers to energy sources which are in themselves sustainable; e.g. they are not considered finite.

Typically these consist of: Hydro, solar, wind, biomass, geothermal and tidal.

Note: it is important when considering the technologies that utilize sustainable energy sources that the total lifetime cost is fully considered (e.g. from manufacturer, deployment, ongoing maintenance, to final disposal). Although the energy source many not be finite, the lifetime of operation of the technology to access them is finite and this should be considered. Basically there is no point in picking a sustainable energy source using a technology which requires constant maintenance or replacement, there is no net benefit to the environment or the consumer of the energy (higher costs and less reliable).
