According the the US Energy Information Administration, over half of US homes are heated by natural gas. I lived the first half of my life in homes heated by gas/forced air systems. A gas forced air system can easily incorporate central air conditioning, automatic humidity control, and electrostatic dust removal. Even an air exchanger. Our heating systems were always very quiet and gave clean, even heating.
Then for 25 years I lived in an all-electric home. It was totally quiet and had the single benefit of having a thermostat in every room. Other than that, it had the major drawback that any baseboard heating system has . . . it doesn't clean or recirculate the air in the house. For the past ten years, we've endured oil/hot water baseboard heat. It's loud. Requires a lot of attention. And it doesn't filter or recirculate the air. It's like using the same bath water over and over again.
We recently replaced our electric range with propane. My wife likes it far better for cooking.
BTW, all gas providers add a chemical called mercaptan to their gas for added safety. A properly maintained gas appliance is VERY unlikely to develop a leak, but were that to happen, the small of mercaptan is unmistakable.
