Besides, everything adds up. Energy cost affects every aspect of life. This is a simplistic view, but on an individual level, lower power bills = lower cost of living = lower wages required. Or, lower power bills = lower cost to run the country = (hopefully) lower taxes = again lower wages required. Hell even the cost of petrol will be affected because instead of using the fuel to generate electricity, there's more to go into cars. And now with EVs, the effect would be even more profound.

It's defo more complicated than the above, but the point is, energy cost is a major input to all these calculations.
