Announced shortage
The yearly average oil consumption is approximatively of 4 billions tons, while our stocks are estimated to be of 140 billions tons. All the serious studies converge and estimate that in less than fifty years our accessible oil reserves will be exhausted. The same applies to natural gaz, potentially available for the next 60 years. What about nuclear power? Many countries have given up nuclear energy as it did not guarantee absolute safety. Hence this energy should not play an important role on the world energetics mix.

In parallel, the rise in energy demand illustrated by the fact that the world electricity production has trebled since 1960, reveals the absolute necessity to find quantitative solutions, but more especially inexhaustible and environment friendly solutions.

The impact on ecosystems
Beyond shortage risks incurred by the planet and their consequences such as the rise in prices; pollution has reached critical level for the ecosystem. Annually, more than 7 billions tons of CO2 are being released in the atmosphere. Let us remind you that only one car produces approximately 3 tons of CO2 per annum.

Necessity of political implication
The facts are there and the solutions offered by the possibilities of photovoltaic energy might sound ambitious but are achievable. However, the development of this inexhaustible source of energy can only be achieved with the help of the countries willing to take a strong political line. Some countries have already understood it.
