Solar radiation has become the world's cheapest energy source

Over the past six years, the cost of solar energy has been steadily declining, overtaking its main competitor, the energy produced by wind turbines. The reduction in the cost of solar energy is largely due to the growth of investments. So in Chile, the cost of 1 MWh is only $ 29.10, which is half the price of a "coal" megawatt.

This is very encouraging news, primarily for developing countries, where the fuel and energy infrastructure is either completely absent or very poorly developed. In this situation, renewables can be a real lifesaver for them, even more so than for an energy giant like the United States, which has also embarked on a phase-out of fossil fuel-based energy.

According to Michael Liebreich, director of Bloomberg New Energy Finance, "renewables are actively entering the era of universal availability."
