According to Bill Gates, climate change is the real issue and we don't want to experiment to see what happens if we don’t change our energy sources. He advocates for government-funded R&D with a long time horizon. Current solutions (solar, wind) are subsidized and have real intermittency issues. Nuclear also has real issues including waste and safety. We shouldn’t be content with where we are and we have to act now to find a mix of zero carbon solutions. He believes the government is actually very effective but just like private investors – many investments and research won’t be successful. U.S. can’t wait for other countries – it must be the leader in this.
