An invention thats needed and would be worth billions

It's not the transformers that are the problem, generally. High efficiency transformers are available that are 99% efficient and even crap transformers are better than 95%.

So if you are drawing 100 Watts, 5 Watts are getting burned up in the crappy transformer, and that's quite a bit but everything is going through the transformer so it gets hot. The real problem is the remaining 95 Watts which are dissipated by the system, mostly as heat, only that loss is distributed over more componants so the heat is less noticable. The real way to heat the transformer less is to reduce the amount of power the rest of the system needs.

Yeah, you could be right - the problem isn't transformers, it's resistors. Someone needs a way to make a resistor that can't and won't heat up.

That would be brilliant, but the real problem is ....

Whatever energy saving thing you develop, it better be cheaper than what's already being used. Why? Because the guy who's designing the gear you're going to buy isn't going to be paying your power bill so he doesn't have to worry about it.

When it comes to consumer items, consumers are dumb on average and don't care how much they will have to pay for power in the furture in whatever form; gas, coal, petrol, electricity. Cheap to buy trumps saves power over time.

Only big companies and municipalities and governments look into that kind of performance. They have accountants who can figure out the number of beans payed over equipment lifetimes. Joe Blo don't know.
