Through its activities of consulting, conception and decision-aiding, ENERS Energy Concept Ltd, in accordance with the principles of sustainability, contributes to the development of energy systems in an integrated way, taking into account at the same time their technical, economic, environmental and social dimension.

A ceaselessly increasing population bound to a global economy rapidly expanding lets augur a larger and larger energy demand. The development of alternative fuels therefore appears essential, when the energy consumption is still essentially based on fossil energy agents, the combustion of which comes along with worrisome effects for the environment.

Energy is an essential factor of the economic development and the social progress of any society. The necessity of satisfying the legitimate needs of all human beings in this domain, without compromising the possibilities of development of the future generations nor modifying seriously the living conditions on our planet in the long term (concept of "sustainability") represents one of the major challenges of our time.

According to most scenarios, the demand of primary energy should continue to increase, and likely in wide proportions (from twice to four times more before 2050). This increase is especially connected to the population growth (probably the doubling of the population in the same period of time) as well as to the improvement of the standard of living, all the more in developing countries.

At present, the world energy demand is satisfied at more than 85% by non-renewable energy such as oil, coal, natural gas or nuclear fuel. The reserves of fossil agents being limited, it will doubtless be necessary to soon return to a consequent use of renewable energy. The expression "second solar era" is sometimes used, by analogy to the pre-industrial period when the totality of the energy consummed originated from the sun (wood, hydraulics, wind). It is advisable from then on to investigate the ways which would, if necessary, allow to limit the consequences of a substantial increase of the price of energy due to the scarcity of fossil reserves.

Another reason for examining the potential of renewable energy is the fact of the substantial environmental impact realted to the combustion of fossil fuels. Even if it is still subject to discussion, the threat of a global warming associated with anthropogenic emissions of CO2 is a matter of great concern, given the possible consequences. The Kyoto Protocol, aimed at regulating the emissions of global warming gases, illustrates the importance given to this issue by a vast majority of countries.
