Natural gas distribution is also leaky, IIRC, and the amount of gas released into the atmosphere is significant. So I wouldn't say electric heating is not "greener", I'm pretty sure it is.

But electric is way more expensive. Natural gas is so cheap (n the northeast US). If it was practical, I'd also seriously switch back to gas powered hot water heater and furnace. A couple years ago I moved from an Apt with hot water and heat included for free from a gas-powered boiler in the basement, to a Condo with its own electric hot water heater and heat-pumps, and it was a bit shocking how much more expensive it is to heat with electricity ... like (very roughly) $30/mo vs $200/mo in winter
