Renewable energy doesn't get used up, in the way that coal and oil do. It is still there the next day, such as sunshine; wind power; water power from rivers and oceans; and geothermal power, which uses the heat deep below the surface of the earth.
%REPLIES% Answer That is in a sense a tough question - But really the question is - Is this a sudden electrical shortage - If so that would mean chaos. That would imply a shortage in fuels used to produce electricity or total breakdown of the elctrical networks. A more likely scenario is…

The Cost of Solar Power The initial cost of solar power varies widely. It depends on how much electricity you use, how much Sun your home gets, and rebates in your area. Generally a typical home solar power system is about $30,000 after state and federal incentives. The system will pay for itself in…

Depending on the size and construction, hydroelectric dams can capture up to 90% of the available energy. Smaller generators may provide as little as 50%.A major consideration is the volume of particulates (silt) impounded by a dam. This may require some energy be allowed to escape.
