Saving electricity with CFL, LED

[Ferrocyanide]

When CFL and LED bulbs advertise that I will save $$$$ by using these bulbs, I am not sure if that is true.

They will over incandescent.  The difference between cfl and led (in $$$) is lower - and led takes the most time to pay back - obvs.  You could quantify exactly how much by referring to your local rates.

I wasn't talking about the price difference of the Bulbs (incandescent vs the rest).

Let's create a hypothetical situation:
Just pretend that all these bulbs are the same price.
Let's also pretend that it is always summer.
If I use these CFL or LED, would it use less joules? Yes.
Would it allow me to save $$$$? I think it depends.

If I am the only one that is using less power, then my bill will be reduced.
If everyone uses less power, the Power Company will notice that suddenly, there is less money coming in.
The Power Company has employees, buildings, expenses. They might have to compensate by increasing the price of electricity.
Or maybe they can fire some employees, abandon some buildings. Somethings got to be cut or the price of electricity has to go up to compensate, so that the Company can pay their employees.

Another example would be gasoline efficient cars. Sure, If I am the only one who invents my own personal super efficient engine + lightweight car, I do save $$$$.
But if everyone does the same, the petrol company is going to notice the large reduction.
What would be the smart thing for the Petrol company to do? Reduce the gasoline prices bc they think more would sell?
What if more doesn’t sell? How long can the Petrol company survive with reduced prices?

The logical thing to do is increase prices. (Unless if you can cut something, like fire employees, close some buildings, cut off the fat).
