I dread to ask, but if harry's vision of the ME refusing to sell oil
comes about, then there's going to be restrictions or rationing or
some form of power cuts, in order to make scarce electricity
production match demand. When the latter happens, his solar panels
won't work and it's very likely his car won't get charged up. He
might live in a zero-energy house now, but ISTM that it isn't a house
that runs with zero-energy input.

So, he's actually worse off than the rest of us.
