Electrical wiring in old houses is definitely a hazard waiting to happen. The good news is most of our appliances and electronics use less power than the old versions. So with a little care, you could be OK.
You really have to be careful plugging in electric heaters, blow driers, electric kettles, irons (things that heat up with electricity), etc. as they draw the most current. If possible, you want to use the outlets on the inside walls if wiring is questionable (as opposed to the outside walls). Inside walls usually do not have insulation and have more room to "breath." So they shouldn't retain heat, will have less direct contact to things that can burn, and will typically give more warning (smell quicker) if something goes amiss.
I foresee a day when our homes will run on 5 volts or 12 volts DC. Almost all electronics these days run on DC (as do LED lights), but we use the power adapters to convert AC back down to DC (and net a power loss/efficiency loss in the process). Solar panels produce DC and we convert that to AC to run in the house, the plug our USB power adapters to run our devices (back to DC). Crazy!!
