Solar power (local and grid), wind power, battery and other storage, heat pumps, EVs.
These will be big wins, eventually, but it will take some time. It may not be quick enough, though. The reason they are easy wins is that they don’t require large scale societal or political change, they can be (and are being) done now, the people that want to make money still make money and end users save money.
It is not likely to be enough, and we DO need large scale societal and political change, but that’s not an easy win, it’s a long hard slog if it’s achievable at all.
