The Future of the Automobile? Part 4 – Five Months In

This is the 4th – and last – in a series discussing my experience driving the all-electric all electric BMW ActiveE. Steady State Impressions Hard to believe it has been 5 months since I picked up my BMW ActiveE. Even harder than you might expect, since I only have 1,614 miles on the odometer – which […]

Utility Bill

Tip 7: Reduce Demand Charges In this final post on energy efficiency in restaurants I will move away from a focus on energy usage to address an area that is less well understood by many people – energy demand. Most restaurants pay not only for the amount of electricity they use in a month – measured in […]
