We did invest, starting in the 1970s, which is what brought the prices down so much. It just took time to get the R&D to the point where they were cost competitive.
The social problem is that fossil fuel usage was very profitable and employed enough people that polluters were allowed not to pay for externalities and a lot of climate change denial funded by the oil companies proved effective at getting politicians and the public to downplay the risk. Even today, even on HN, you can find people who’ll say it’s no big deal, the earth has been this warm in the past, that it’ll cost too much, that they can never drive an EV because their daily commute is 11 hours each way without stopping, etc.
Because fossil fuel lobbyists so successfully captured most right-wing parties, millions of people added that to their self identity and thus will struggle to admit they were wrong because that more or less means admitting that the same people who lied to them about the climate also lied about other things.
