A few thoughts on the state of things

[Highlander]

Welcome to the forum,.. from the Scottish Highlands.

You are certainly on the right track, and have come up with some good ideas, I would also suggest that you gather some smaller value currency in the form of rings or ear rings

You said you have leant to grow food, great,.. you also say that you want to look at getting more from the garage,... is it possible you could combine the two, if you could remove the roof, you have a very secure garden tucked away

Solar panels are really a must, even if the power stayed on, it will likely be very intermittent and for the cost of a 40 - 50 watt panel, you have to have at least one,... but also think about wind up goods like a world net radio
