If you could drive the unit costs of electricity low enough for it to be cheaper than natural gas for heating, you could see major growth from that. Obviously, not likely to happen anytime soon, but if the cost-reduction progression of renewables continues, it could become viable in the medium-term. Currently it's far more expensive to heat with electric than natural gas, so most people with access to it don't use electric.
