Clean electricity technologies might solve the climate crisis

As the global heating advances and starts to show how dramatic it can be, a new fact brings really good hopes. I happens that the cost of both photoelectric and wind power electricity is decreasing at a very fast pace. This is a very well-timed example of the effect of the learning experience on the production of a good. As the experience advances with the cumulative production, the cost of a unit decreases. This phenomenon is quantitatively described by the Wright’s law, that says: every time the cumulative production of a product doubles, its cost decreases by a fixed factor, specific of that product. Its effect is more perceptible in products of recent commercial production, as is the case with both solar panels and wind moved electrical plants. Electricity produced by both sun light and wind power is already cheaper than that produced by burning fossil fuels, and its cost continues to decrease at incredible pace. It is reasonable to hope that the carbon neutrality will be achieved sooner than promised by governments. Brazil, quite sunny and endowed with large wind power potential, with some delay is exploiting those resources to make its electric energy even cleaner.
