As CCCPNeverAgain said, even this is way to extreme and unnecessary.

You can buy cheap "pay as you go" phone plans. Get one streaming service that you are going to use, and then share another. AC is perfectly fine (and in many cases necessary) so long as you have good insulation. Worse case: make a single "cool" room for your house. Normally a good option is the basement for the summer, then a warm room for the winter (like a loft)

Everything else is what a responsible adult should be doing anyways.
