What? Are there current control towers that run on something besides electricity from the grid? What is this actually talking about, backup generators?
Natural gas heat. It’s keeping in line with administration policy on climate change, electrification, etc. Building energy use is a substantial component of national energy consumption. Proper insulation and high performance building standards means heat pumps should be sufficient (and can run off diesel generators air traffic control infra would run on in a power outage regardless, as it’s critical infrastructure).
Cost savings are there too, the grid gets cleaner and cheaper over time as renewables penetration hockey stick growth curve. Furnaces and boilers burn gas their entire lifetime.
