Well, yes? That seems somewhat uncontroversial? There are a lot of people out there who need more electricity and can't afford it. Electricity is one of the most fungible forms of energy, with infinite electricity we could all live like kings. It'd be very comfortable. The limit on use is the supply-demand balance represented by prices and if price were low enough people would up their living standards.
That is also the explanation for a lot of the issues your post goes to. If you don't need to use the electricity, someone who is struggling can use it instead. And the way the math shakes out is it'd normally be economically optimum to increase their access to a good standard of living by giving them more energy than you gave up. These effects are over the entire economy.
And I do want to plug what Citizen_Lame said in a sibling comment, the obsession with lightbulbs whenever energy comes up is a bit odd. If I were relying on HN comment threads I'd believe households in the UK were composed of nothing but light-bulbs and consumed nothing but the same given how much of a focus they are of the energy policy.
