Deregulated energy markets accelerate solar adoption

Deregulating a basic human need and leaving it to the 'market' to solve this. This sounds a lot like other privatization efforts of the past decades.

In my country healthcare, child support, energy, national railway, postal services, public housing, banking and more have all been privatized.

I worry about this. Not for now, but for 20 years in the future, where all energy is managed by companies and the government can no longer control the market due to being 'too big too fail' and because it gave all control away.

There is nothing wrong with markets solving basic human needs as long as the incentives are properly aligned.

How does one properly align the incentives of people and corporations?
