Weariness with dystopian plots, coupled with a growing awareness of climate change, has been a driving force in the renewed interest in ecological science fiction in the 2010s.
Brazil is actually one of the world’s leaders in renewable energy, with 76% of the country’s energy in 2017 coming from wind, solar, and hydropower.
“Generally speaking, more energy is extracted from a liter of oil than from a kilo of cane. And the global demand only increases. Soon we will reach a point where it will again make sense, economic sense, at least to extract and refine oil, as it was done in the twentieth century. Unless we can extract more energy from plants.”
“Cellulose?”
“Cellulose, yes. Plants are made of things other than sugar, such as cellulose, fat, and protein, and there are biological pathways to convert all of those into fuel. The point is only about price and unwanted waste. Cellulose started to be a part of the scene in the beginning of the century. Animal fat has been used for decades to produce aviation kerosene. Protein is the new frontier, mainly because of waste.”
“Waste?”
“Ammonia. Nitrates. In the old days, people thought that this wouldn’t be a problem, that after yeast and bacteria finished turning the protein into fuel, the part with the nitrogen could be reused as fertilizer. A closed cycle: nitrates for soil, soil for plant, plant for nitrates. But then… Have you ever heard of nitrogen pollution?”
I shook my head. He swallowed three more olives.
“Bottom line, having loose nitrogen compounds in the soil, air, and water is not a good idea. Acid rain. Pollution of lakes and oceans. Bad, really bad. Not at first, but over time… Synthetic fertilizers had to be regulated almost to extinction some ten years ago. Hence, the golden dream of the protein biofuel was sent to the compost heap.”
“Unless someone invented a process that could neutralize nitrogen,” I added. “Which was what Raul and Sabrina were working on.”
After the unification of the planet, the Rebouças brothers’ study showed the dangers of greenhouse effect amplification for the climate and the planetary environment, after which UN resolutions increasingly restricted the use of fossil fuels. And also of nuclear energy, after its risks were evidenced when an earthquake followed by tsunami devastated the plant of Paramonga, in the Tauantinsuio.
Fifty years later, there were only thirty experimental nuclear power plants and three hundred small research reactors operating in the world, all under strict supervision by the Union of Nations Commission on Science and Culture. And coal, oil, and gas were being used only as chemical raw materials. Former mining and industrial centers disappeared in many places. Although the Union financed the substitution of renewable energy sources, the imposition aroused much resentment in Eurasia, where many saw the threat of global warming as a forged pretext to deprive them of their technological independence and subject them to the uniform and oppressive vulgarity of solar panels and wind turbines that turned magnificent landscapes in ugly things to behold.
“Can’t you go faster, Corporal?” asked Marinetti.
“No, mein Führer, the machine will follow the normal programming.”
“Could they not? Can the Union stop the damn engine?” he asked furiously.
“Rosenberg and Salazar were able to cut off the communication, the cameras, and the locks, but they didn’t figure out how to take direct control without damaging everything.”
“Maledetto robot!” he mumbled. “In the new order, vehicles will have steering wheels, brakes, and accelerating pedals. A machine is a woman, and it’s not fitting for it to refuse a man’s command!”
