When it comes to climate change, I know innovation isn’t the only thing we need. But we cannot keep the earth… — Bill Gates

To get [the breakthroughs on the "Technologies needed" list] ready soon enough to make a difference, governments need to . . . [q]uintuple clean energy and climate-related R&D over the next decade. . . .

It helps to set ambitious goals and commit to meeting them, the way countries around the world did with the 2015 Paris Agreement. It’s easy to mock international agreements, but they’re part of how progress happens: If you like having an ozone layer, you can thank an international agreement called the Montreal Protocol.

Deploying today’s renewables and improving transmission couldn’t be more important. . . . Unless we use large amounts of nuclear energy . . . every path to zero in the United States will require us to install as much wind and solar power as we can build and find room for. . . . [M]ost countries aren’t as lucky as the United States when it comes to solar and wind resources. . . . That’s why, even as we deploy, deploy, deploy solar and wind, the world is going to need some new clean electricity inventions too.
