Sustainable development bases

Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. 


It contains within it two key concepts:

The concept of needs, in particular the essential needs of the world's poor, to which overriding priority should be given; and the idea of limitations imposed by the state of technology and social organization on the environment's ability to meet present and future needs.

Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy.Some ways in which sustainable energy has been defined are:

• "Effectively, the provision of energy such that it meets the needs of the present without compromising the ability of future generations to meet their own needs. ...Sustainable Energy has two key components: renewable energy and energy efficiency." – Renewable Energy and Efficiency Partnership .
• "Dynamic harmony between equitable availability of energy-intensive goods and services to all people and the preservation of the earth for future generations." And, "the solution will lie in finding sustainable energy sources and more efficient means of converting and utilizing energy." – Sustainable energy by J. W. Tester, et al., from MIT Press.
• "Any energy generation, efficiency & conservation source where: Resources are available to enable massive scaling to become a significant portion of energy generation, long term, preferably 100 years.." –Invest, a green technology non-profit organization.
• "Energy which is replenishable within a human lifetime and causes no long-term damage to the environment." 

Also among all development regions   , AFRICA among all developing regions is undoubtedtly the continent's electricity needs are most urgent. I live on this moment   without electricity and this situation is qualified normal .


On our continent 65 % have not access to the energy wich is neverthless a essential matter to the next goals....
