Unnecessary draws of electrical energy or unneeded plug load are a significant energy drain for corporations. One Fortune 500 firm with an yearly electricity spend of over $90mm estimates that 40% of this electricity is due to plug load from employees and has implemented programs to reduce employee plug load.
I really like solutions which reduce electricity use but cause no or very little disruption to daily operations and require very little human behavior change. Two promising products are:
Watt Stopper by Isole

This is a simple device which uses a motion detector to shut off the electricity to vending machines when there is no movement in front of them. The average vending machine uses $200-300 a year in electricity (depending on cost of local electricity) and this tool can reduce energy use by 40-50%. Over 300,000 units have been installed in North America.
