Yes, a lot of homes in the US use natural gas for all heating (forced air, water, cooking, clothes drying). The usage is minimal in the summer months (just cooking and hot water and some clothes), but can spike to very high amounts when the temperature drops to below freezing.

Usually a home will be built with all gas appliances or all electric, a mixture of the two is not as common.

There are cultural differences too. Americans love to air condition their entire homes with central systems and run them a lot in the summer months. They also dry their clothes with automatic dryers and rarely use clothes lines anymore.
