The main sources of energy at the moment on the planet are (unfortunately) coal and oil. Two not only polluting resources, but also finite. Global warming has already begun to reduce and the only viable solution is to turn to renewable energy, which has no negative aspects. RES are environmentally friendly sources as they do not produce emissions, and their technology can also be adoptedwithout consequences. Science has opened the road to RES utilization since a long time ago. Now the only thing left is the existence of political will, while at the same time financially disengaging from the big oil companies, to direct every effort to the only safe and sustainable road.
