That’s no accident. It’s the result of policy interventions from the US to Germany to China. As policy analyst Gregory Nemet puts it, “No one country is responsible. It was a relay race rather than a competition.” The global flow of knowledge, people, technology, and policy helped bring down the price per watt from more than $100 in 1976 to less than $0.50 today, according to this analysis from the folks at Our World in Data. https://ourworldindata.org/cheap-renewables-growth If we can learn the right lessons from solar’s success, it could help us develop and deploy the technology we need to keep our planet habitable and avoid the worst impacts of climate change.
