Climate change is not the only environmental problem we’re facing, but it’s the most critical. Many people agree, but as we’ve tried to explain in our book, Climate Gamble, not many countries are taking the danger seriously. After all, the best successes in the fight against climate change have been achieved entirely accidentally – by countries that didn’t even think about reducing CO2 emissions. These countries achieved the feat already in the 1980s by building nuclear power. Even more remarkably, unlike plans that require drastic decreases in energy use, multiple countries (France and Sweden foremost among them) were able to significantly cut CO2 emissions by building nuclear power, despite not even trying to reduce CO2 emissions and while energy use increased.
It’s too early to say with any certainty what a future low-carbon energy system will look like. However, given what’s at stake, it would be far too early to dismiss the most scalable source of low-carbon energy humanity has ever tried.
