I guess it depends a lot on your situation, but for OP's method to be effective you need to out-compete other breeding grounds in not only your backyard but also X feet/meters away (whatever distance mosquitoes typically fly to "hunt").

If there's a nice shallow pond on the property line 100 feet from your porch (or water filled tires at the sloppy neighbour or whatever it might be), I seriously doubt the efficacy of the method in the article.

This thing would lure in any mosquitoes (and unfortunately other things, as per sibling comment) that fly in your backyard, wherever they come from.

For electricity: That also of course depends, but around here it's not uncommon to have an outlet on the outside of some garage or outbuilding or something. The product I linked have a 50 feet cord as well. The fan noise has not been noticeable at all when I've seen it.
