If you had to pick one technology to target in the bid to reduce global energy consumption, the motor would have to be one of the top candidates. The International Energy Agency (IEA) estimated in 2011 that close to half of global electricity production was consumed by electric motor-driven systems, drawing more than 7,000TWh a year and rising steadily. If not curtailed, the trend points to consumption of more than 13,000TWh per year by 2030.
