Leading investment bank UBS says the payback time for unsubsidized investment in electric vehicles paired with rooftop solar and battery storage will be as low as six to eight years by 2020, potentially triggering a massive shift in the energy industry.
"It's time to join the revolution," UBS wrote in a note to clients, in what could be interpreted as a pointed rejoinder to those governments and corporates that believe centralized fossil-fuel generation will continue to dominate for decades to come.
By 2030, according to UBS analysts, this combination will deliver a payback time of around three years. Right now, the payback is probably around twelve years, enough to encourage the interest of early adopters. (You can read more here on why EVs will make solar viable without subsidies.)
