That's great, but fossil fuels are often available in the event of a power outage, and that can save lives during a winter storm. Availability is just as important as efficiency, and until we can make our power grid more resilient, we need to factor that in.
The vast majority of gas boilers use electronics to function. In a powercut they are also dead.
Now if you're talking diesel generator back ups, then far enough.
If it's just control systems though, they may be able to run off of a UPS for a day or so.
There are fans and pumps as well.
