Is it just me or does anyone else think the power generators are not necessary? An electric oven does not need fire to make it work, I get the electric oven is an upgrade but i would think a handiworker would be more appropriate to cook rather than fire/kindling same with the heating, cooling, furnaces and crafting tables etc generally if something is electric, other than placing raw materials in, the machine does everything itself. It would be more realistic to need to upgrade the power generator to accommodate more electrical items than have an electric oven that needs fire to make it work. Just my opinion though.
