Net-zero home eliminates energy costs
Last year, Jeff and Rachel Hohensee’s winter energy bill was $500.

This year, they don’t even have an energy bill. Jeff, a consultant on sustainable-living topics at Natural Capitalism Solutions, was feeling guilty about his energy-wasting home, so he and his wife set out on a two-year project that transformed it into a net-zero home–meaning it generates more energy than it uses.
They started with easy fixes like switching to CFL bulbs and low-flow showerheads, and getting an energy audit to see where air was leaking from their home. They used caulk and insulation foam to fill the leaky areas.
Eventually, they hired insulators to add materials to the home’s walls. Jeff says they took the process to a higher level by hiring someone from Standard Renewable Energy to follow the insulators with an infrared gun. The infrared photos would show areas where the initial insulation was too sparse, and more was added. Read more
Check out at the library to check out your energy use

Kill-A-Watt meter by P3.
Now you can check out a power meter when you check out your books at the Boulder Public Library.
(Assuming you do still check out books at the library….)
The city of Boulder just purchased 18 Kill-A-Watt meters that can be checked out for three weeks at a time.
To make it work, you plug it into the wall, and then plug your appliance (fridge, cell phone charger, laptop, etc.) into the Kill-A-Watt.
The meter tells you how much your devices pull off the grid — even when they’re not on.
