I understand the forum is to ask for help among other things. But this is the kind of question that for me is annoying and ridiculous. I can be answered only by your awareness of your own circumstances.
Stop being lazy and research about the technology, electricity costs, and do the math. You will have then the precise answer that applies to you.
Sorry about the rant, but I've seen the question so many times and I am tired of people that won't do their homework and just want help for all things
