Transitioning to renewable energy will save the world $18 trillion

Past models predicting high costs for transitioning to zero carbon energy have deterred companies from investing and made governments nervous about setting policies that will accelerate the energy transition and cut reliance on fossil fuels. Renewable costs have been trending down for decades. They are already cheaper than fossil fuels in many situations, and our research shows they will become cheaper than fossil fuels across almost all applications in the years to come.
