It's not the electricity. It's how we produce it.
Solar panels, wind turbines, nuclear reactors, and water wheels can be used to produce electricity with no effect on climate.
Coal, oil, wood, gasoline, natural gas, household trash, and tall dry grass can be burned to boil water to make steam to turn a generator and make electricity. When everybody does that, the burning releases enough Carbon Dioxide into the atmosphere to futz up the Earth's climates. That's exactly what we have done for the past 200 years.
