<br /><br /> Solar power is the cheapest renewable energy source for small-scale use, such as pocket calculators, LED lights, and remote (small) electrical appliances. Hydroelectric power is the cheapest renewable energy source for large-scale production. That is, it has the lowest cost to construct and maintain the generating facilities compared to the amount of energy produced.
[No, it isn't that easy. The simple part is that nuclear power is better than fossil fuels on any account. Far less pollution, far more fuel available, less disruption through mining, fewer deaths due to accidents.Solar power is still better on a few accounts: still more fuel available, even less accident potential.he current system is a mix of fossil fuels, hydroelectric power, and nuclear power. The sustainable energy fraction is miniscule. When you compute everything in terms of net thermodynamic output, the sustainable energy fraction is not just miniscule but entirely negligible.
