This is why I worry what will happen when we go Net Zero and are completely dependent on electricity for all domestic energy.
In the past, and still for some, for those in gas supply areas - which are the majority of us, there was often a gas fire in the living room and/or a gas cooker in the kitchen that could be used for warmth if the electricity went down.
As Elbelle has discussed, in rural area people have solid fuel appliances for all or back up heating and cooking. However in the future, when the power goes down, that is it, the old and ill and other vulnerable people will have no alternative energy source for any use; neither heating, hot drinks, nor washing.
We have just moved into an old house with large open fireplaces and our first thought was, on environmental grounds, that we would fit a coupleof electric looklike wood burners in a couple of the fireplaces, but then the problems listed above occurred to us and in our last home we did experience 2 weeks without gas and six months of interupted gas supplies and we were very grateful for our wood burner. We even used the top of it as a slow cooker.
