How often do you start your Windows?

We HAVE to stop wasting energy. The difference between wasting and using should be given by the necessity.

I need to keep the fridge working for maintaining the food.
I need to keep the air conditioner running for sleeping.
I need to keep the PC overnight if the PC is rendering a 3D video.
I don't need to keep the air conditioner running if I'm not at home.
I don't need to keep the PC running overnight if won't be doing something useful.

No matter how much energy is being consumed. The point is: "Do I really need to consume it?"

Who determines one's necessity? Should everyone email Leo first before they hit the power on button?

I don't use air conditioning and I don't watch TV. I bet you do both of those things. I think I use less energy than you.

English is not my first language (I know my wording looks a little awkward). But I think the message I wrote wasn't that bad.
I didn't even suggested that people has to ask me about their needs. All I said was "use the energy that you really need".

If pretending to misunderstand me is all the argument you have. Well, that's disappointing.

My argument is clear by now, I hope. Stop using the energy you already know you don't really need to use. A second step and much better would be reducing the use of energy for superfluous needs (like watching TV).

By the way I don't watch TV. And I use the air conditioner because the temperature here is 89.6 degrees Fahrenheit and will reach 96ºF about January.

If English isn't your first langauge, no te preocupes, porque hablo español tambien. Entiendo todo lo que dices.

La energia que uno requeire es diferente para todo y uno no se puede decir al otro cuanto usar.

Does that make sense or not?

Your Spanish is good!

Nobody can tell you how much energy you need. And there's no need to tell you how much you can save (for your economy and the environment). You already know how much you can save.

That's correct.
