Energy: firm and variable sources

Each energy source has its own characteristic. Two extremes: those that can be dispatched practically 100% of the time at nominal capacity like thermal plants, to those that offer about 20% like solar ones.

Of course, each source has its advantages, disadvantages, and associated costs considering its life cycle.

We are already in Brazil at a maturity stage where each consumer can and should choose the source or portfolio of sources that best fits his or her profile of interests or conveniences.

The times are for "market driven decisions" and not "a dictated solution" especially since in Brazil subsidies are borne by customers who are obliged to pay tariffs without actually being consulted.
