The cinema documentary "THE 4TH REVOLUTION – EnergyAutonomy" - www.energyautonomy.org - describes the possibility to switch to 100% renewable.
Sun, wind, hydro and geothermal energy are natural sources accessible to everyone all over the world without making any difference. And they are renewable, free and available in the long run.
The documentary demonstrates the opportunities which will be provided by the energy revolution regarding the sustainable economic development, social and economic fairness.
The film aims to raise awareness and to lead towards the dawn of the solar age, also named in a more sophisticated manner - the "Green Kondratieff" (also see: the Kondratieff-Cycle).
Key to a strong and sustainable economy in the future seems to lie in increased resource and energy efficiency. Growth will probably be generated from a mix of economics, ecology, and social commitment.
current financial crisis should kick-start a new cycle of green prosperity.
