New York is One of the Least Energy-Expensive States July tends to be the hottest month, and people are cranking those air conditioners. Make you wonder how much energy we used up in New York, as well as the cost when compared to the rest of the country. Energy costs will eat up between five and twenty percent of a families' income, with Americans with lower incomes paying the highest of that range. Of course, that's how it works out, I'm sure your eyes are rolling like mine. Lower energy prices don't necessarily translate into savings. Where you live and how much energy you use is a big part of the equation.
