Sustainable energy is the way we produce and use energy that allows sustainable development, respect for nature and human being. This concept involves two key components, one from the standpoint of production (renewable energy) and another related to its use, efficiency and energy savings. It is therefore a broad approach which fits into a comprehensive sustainable development.

The energy efficiency opportunities are numerous, related to efficiency and energy savings (e.g. use of low energy light bulbs, LEDs lamps, measuring and optimizing electricity consumption for domestic and industrial sites, etc.).

As you can understand, speaking of sustainable energy involves many aspects of both technical / scientific environment. Efficiency and savings are considered "sustainable energy" to all effects, allowing a development environment in terms of quality and quantity of heritage and nature reserves.
