At the end of December, news outlets were reporting a startling development. Energy use in US homes had fallen to 2001 levels. This reduction in energy demand happened while more of us are using computers as a part of our daily (i.e., non-business) lives and all sorts of electronic gadgets litter our homes.
There are many reasons for this. More laptops and fewer desktop models mean less energy demand even though we use computers more. Now tablets and phones are multiplying as well, but competing over weight, size and battery life – all of which means using energy more efficiently. LED backlighting has made many flat-screen TVs – energy hogs when they were first introduced – more energy efficient than the old cathode ray tube models.
