House improvements energy wise

I live in a house that is about a 100 years old. The walls are solid and act as radiators. With energy prices rising and set to rise much higher (IMHO) I have decided invest in materials and systems to severely limit my use of the National Grid and Gas supplies. The goal is to be able to survive on energy generated from solar panels and wind stored in special batteries combined with super insulation of the house.
Also water heating and space heating through solar.
Also the use of a woodburner.

Submarine batteries are perfect for the job, very heavy and hard to find. Also good are electric operated stacker truck batteries also very heavy.

Some chap sells batteries on Ebay which he says are deep cycle but are not. It's easy to get caught out. I've bought off Ebay some solar cells which are superior to those produced by Sharps in Llay.
They only cost £4 to post from the USA. You have to solder them together and put them in a metal frame.
