Gale is right, that our electric costs are way down right now, by comparison to what our parents and grandparents paid. Electric rates have not climbed nearly as fast as median salary, cost of living, or any other metric you'd like to use for comparison. Eight seconds on Google will show you that median household income has increased almost 4x since 1980, but average US electric rates are only up 2.5x, and the divergence is worse the farther you go back.
But rate hikes are happening now. Just look at what's been happening in much of New England. While the historic trend is downward, WRT median salary or cost of living, I don't believe it's going to continue to trend toward zero.
But more than cost, the thing that bothers many is the dependency on a utility. Firewood, heating oil, propane... these can all be easily stocked at home. A storm or simple utility management F'up doesn't interrupt those services and leave you cold and helpless, like loss of your electric power.
With the conversion to this "all electric future" seeming inevitable, it might be wise to steer some investment money toward companies aiming to resolve this issues, like those making whole-house generator and battery systems. There is no doubt in my mind that, as people convert ICE's and oil-fired boilers to EV's and heat pumps, that there will be more demand for backup electric power systems. If I'm dependent on electric for heating, you'd damn well better believe I'm going to have a whole-house generator sitting outside and plumbed into a propane tank buried in the back yard, so that I'm not one of those left out in the cold when the utility goes down.
