The biggest problem with our planet today is the production of energy from renewable sources, but on condition of preserving the environment. Resources such as oil, solid fuels and hydropower are limited and increasingly adverse effects on the environment. The solution to this problem lies in renewable energy sources such as solar energy, wind energy, geothermal energy, tidal energy. Increasing the proportion of renewable energy sources is a prerequisite for the sustainability of our planet, as well as economic progress.

The growing unemployment of the population should be resolved with the implementation of all measures for the preservation of the planet and uses of renewable energy sources.
