Despite all the new high tech ways to help us curb our energy consumption, only about a quarter of us are expected to be interested in using home energy management dashboards and online energy management websites, says Ogi Kavazovic, Senior Director, Marketing & Strategy, for energy software startup Positive Energy, which this morning rebranded itself as Opower. That leaves a good three quarters of utility customers that will need something decidedly more low-tech . . . . like the paper-mailed energy-efficiency reports that Opower develops in addition to its software tools. Well, that’s the company’s pitch and utilities seem to be responding — Opower also said this morning that it’s signed up more than 20 utility customers for its energy efficiency tools, which can lower consumer’s energy consumption by as much as 3.5 percent.
