Local energies
|
The NRE, the new and renewable energies, are considered as expensive, complex to implement and of small efficiency. As much preconceived ideas which limit their development at large scale. These energies are local, that is to say they cannot be used everywhere, anyhow. The energy power, but also the local needs must be assessed and their appropriateness must be examined. They must also be accepted by the population in order to guarantee their lifetime. The renewable energies implementation requires therefore important efforts : technical analysis, socioeconomic study, activity and local information... There is no already made solution, but methodologies for projects implementation, technically, socially and economically viable. The ALIZES projects (MAURITANIA and SENEGAL) have demonstrated that by concentrating technical and human means on a determined area, we can obtain a "critical mass" which allows to perpetuate a whole activity, from the installation to the equipments maintenance. |

Without forgetting that the renewable energies, inexhaustible by definition, are respectful of environment !

Concerning
wind energy i Africa :
"Although much of Africa lies within the equatorial belt which has a lower wind resource compared to countries trade winds prevalent in the latitudes of Europe and North America. However, there is considerable potential for large scale development in the north and south of the continent and still the possibility of small scale projects in the central region. In 2002 there was 148 MW of installed capacity for wind power generation on the African continent, a mere 0.5% of the global total. A study published by the European Wind Energy Association on global markets for wind energy expects the growth of wind power to reach 150 MW per annum by 2007, with the installed capacity between 620 and 1000 MW, depending on market conditions. Factors that boost the prospects of the wind market in Africa include a high future demand for electricity generating capacity in the region, and the enthusiasm of international donors to invest in clean energy schemes. However, the political priorities of governments, their policies on energy, electricity and climate change, as well as their ability to act on such policies remain a huge issue for wind energy projects in all African countries."
