In their book "The Big Fix", Hal Harvey and Justin Gillis explain how solving climate change depends on ensuring that technologies like wind, solar, batteries, and EVs move rapidly down the technological "learning curve". The more we invest in scaling these technologies, the cheaper, better, and more efficient they will get.

This is already happening for renewables, which are now the cheapest form of energy by far. We need to continue investing in renewables so they fully take over the energy market, while applying the same approach to EVs, new battery technologies, green concrete, and more.
