Ok - why not get some solar panels then, if you face the right way? Coming to an Ikea near you soon, apparently!
And/or buy electricity suppliers.
And/or rental property - with a long, fixed rate low interest mortgage (shame you can't do what the Americans can with the 30 year fix... well, I guess you can, my friend had a fixed-for-the-life-of-the-mortgage mortgage.. about 2 or 3% higher than a 3 year one I guess).
People need somewhere to live, food to eat, etc. Buy stocks of the companies that provide that, or provide it yourself, and you'll be ok - IMHO.
I'm.. kinda retired, ish, early thirties. On the basis of a rental property, and not too much else. I'm sure it'll work out!
