Utilities in general represent no real upside to the public since we opted to farm them out.
Consumers have little choice on electricity, even worse for gas, and worse still for water. Competition is practically zero. The infrastructure is poor, failing, and often largely ignored. Investment in solar, wind and tidal has amounted to token gestures over the years, and often the commercial frameworks have been poor.
Basic power, heat, and water provision shouldn't even need to be a political issue. We all need these things, and if there is no competition it makes more sense to provide the domestic end without charge and tax accordingly. This stops it hitting the poorest the most, removes the politics, and makes the whole thing more efficient. We need to stop these antiquated views that in-housing certain things is somehow a nod to the far left - if there's no free market, people are being ripped off under a false offer.
