The average household spends around $2,000 per year on energy bills, half of which goes to heating and cooling alone.
But energy has much broader implications on the national economy and the environment. According to a McKinsey & Company report, an estimated $520 billion initial investment on energy-efficiency measures could save the economy more than $1.2 trillion in the future and potentially reduce annual greenhouse gas emissions by 1.1 gigatons — “the equivalent of taking the entire U.S. fleet of passenger vehicles and light trucks off the roads.”
WalletHub's Richie Bernardo presents 2016's most and least energy efficient states. The analysis looked at the efficiency of car- and home-energy consumption in 48 U.S. states (the study excluded Alaska and Hawaii).
New York topped the list, followed by Utah, Minnesota, Vermont, and Rhode Island as the most energy efficient states overall. But states in the South lag behind. South Carolina was the least energy efficient state, followed by Louisiana, Alabama, Arkansas, and Mississippi.
