* Cheap EV chargers for people who don’t own houses. Young people are the most likely to be open to EVs, but they’re also the least likely to own a house. Charging is a major barrier to entry. Create something so cheap and ubiquitous that charging is not a concern. For example chargers built into lamp posts.
* Figure out UHVDC to enable clean energy surpluses to be sold internationally. Reliable UHVDC networks will allow clean energy projects to service more geographic area, making them more competitive. Eventually, storage might not even be necessary, since dark/non-windy regions can always pull from regions with wind or sun. And when fusion power comes online in a few decades, huge energy surpluses will be very profitable.
* Passive carbon capture via nuclear barges. We’ve had nuclear reactors in the water for decades, let’s put them to use capturing carbon.
* Floatovoltaics. Land isn’t always cheap. Put solar panels in other places. There are other positive side effects as well, such as reducing algae blooms and reducing evaporation.
