Resumo:

Typically, every time Brazil faces an energy crisis (oil increase or water/electricity shortages) ends up with a new emphasis to expand RE, in particular biofuels. This was the case during the energy crisis of 1920s, WWII, 1973, 1979, 2007, and now in 2022. Different reasons precipitated these crises, all of them affecting Brazil, both from the energy or the economic points of view. The difference now is that new increase of oil prices, due to the Russian war on Ukraine, coincides with an energy transition process that will take decades.
