The law of Ukraine On alternative sources of energy refers to alternative energy sources: solar, wind, geothermal, hydrothermal, marine and hydrokinetic energy, hydroelectricity, biomass, landfill biogas and others.
Unfortunately there is no non-circular proof of energy conservation -- in the end, all laws of physics that we know of are the result of observation, formation of hypotheses, making predictions, and testing them. Conservation of energy is one such law. If energy could be created or destroyed, all of our ideas of how the world works would have to be modified in some way (and wed learn something very perplexing). But so far, energy seems not to be created or destroyed. Energy can be converted from one form to another, though.
