If you believe this, then you do not understand the actual challenges.
Solar has dropped to the point that it is a viable investment for a homeowner, but the real challenge
is how to make a supply with less than a 50% duty cycle of production, cover 100% of demand.
At this point the government involvement we need is to unify and streamline home solar grid connection,
to something that both homeowner and electrical utility can survive.
What you need a combination of different energy sources and types of storages. That already today you for example have solar panels, wind power, concentrated solar power with thermal storage, hydropower and sustainable biofuels. You also have different types of storage like for example batteries and pumped-storage hydroelectricity.
There already with present technologies Scotland gets 70 percent of it’s electricity from renewables in 2017.

While Denmark got 44 percent of its electricity from renewables in 2017 and plane to get 80 percent of it’s electricity from renewables in 2020.

So many countries can learn from those and many more positive examples happening right now. Like for example that over half new cars was electric in Norway in 2017.

That the same time you continue to see a rapid technology development in both renewable energy and storage solutions. While you will also new emerging technologies like for example wave power, tidal power, e-fuels and hydrogen storage during the coming decades. So, for example Sweden’s goal of being carbon neutral by 2045 is a realistic target.
