Renewable Energies

In the last years, many countries have used each time more renewable energies, not just because fossil energies are limited, but because people are thinking on the climate changes. Every day are made investments in wind energy, hydro energy, solar energy and biomass with the purpose of minimize the environmental impacts and increase the global energy without the use of fossil fuels, but that´s not enough.
Global population should decrease their energetic consume and try always improve, using technologies that help the humanity become less dependent on fossil fuels.
Environmental debates should be discussed between the politicians in order to teach how to save energy and alert people for the dangers that our Planet´s health is dealing.
