Because they're going to lower the price of electricity if they can cut jobs, right? Wrong! they'll just increase their profit!
You know what happens when everyone starts consuming less electricity due to solar power, smart meters, led screens, led lighting, energy-saving dish-washers and washing machines? They just raise the price of electricity. This has been happening here (Belgium) for years now. They just disguise this under "environmental friendly measures" to teach people to be more "ecology minded". But if everyone consumes 20% less, prices are not going to drop 20%. They still need to make money, so they'll raise them instead.
