There's no such thing as zero-impact. Wind farms have an environmental impact. Building solar-sensitive cells require dirty processes that also create pollution and waste as they don't last forever.
The important part to remember is that natural gas infrastructure is always polluting, and tends to leak a fair amount of fuel which is never even used (around me, there are estimated that this is as high as a third of the total usage). That’s all locked in when you use gas, whereas an electric stove can be powered by a mix of sources which change hourly without the owner even having to know about it.
The other thing to consider is that a professionally-managed and monitored power plant is usually better than equipment as maintained by the average person. Lots of people don’t even get their gas appliances checked once a year on average, and you’ll pretty regularly hear about leaks or fires caused by poor maintenance at apartment buildings where you’d think they’d be at least a little more responsible.
Efficiency wise you may be wrong. Carrying electricity is not efficient (you lose energy with distance) while gas (as long as leaks are limited) is a more efficient store of energy from start to end.
