The FUTURE of Renewable Energy Sources

Human society needs energy to grow and energy consumption increases every year. One has to think not only about the meeting of current demand, but also about a sustainable energetics concept that will secure sufficient energy supplies in the future as well. Fossil fuel deposits are gradually being depleted and the only thing that can replace them, besides nuclear energy, is renewable sources. In the long run, the whole world will be powered predominantly by energy from the Sun, wind and biomass.
