There are options for energy. Lots of options, for the individual. However the individual in a lot of cases can not afford them. Solar, wind heat sink building, local geothermal.
Battery tech it seems is improving a lot, but after the headlines of battery improvement, no new stories get put out.
Nuclear is know, and has improved. Nuclear has not only provided power it has provided the power for alternative energy production. People tend to have that "not in my backyard" attitude toward it, so it foster the urge of many to find alternatives.
I hope they do go nuclear, more countries need to shore up their energy production, this will bring more alternative energy people into the game from more parts of the world.
geothermal heating here is about 30K for a household. we have an air/water heat exchange system which is about 70% of that price, but still needs enough electricity to make price increases painful.
Would love a solar roof array, at least for 8 months of the year, but it is well out of our price range currently. We have to replace the roof and if we could go full solar, we would - but costs...
There are also new options for "mini nuclear" reactors, that produce far less but are fast and much cheaper to build. Having them spread around might be a better option.
As the cost of electricity goes up, as it is here also going up, there hopefully will be people willing to find cheaper alternatives to offer home owners. Solar took a pretty big hit in America when the electric companies started to lose money from people disconnecting. They cried foul because of all the lines and telephone poles they need to maintain, so started charging even people not connected to the power company for maintaining the infrastructure. It all started in Oklahoma State. They were the first to start charging people. So that made solar even more expensive since people still had an electric bill.
It seems the home owners are screwed no matter what they do to try and save money.
