LED Lighting, 6-month update

Background

Ok, back in November 2012 I stumbled into my local 'big-box' home improvement store with an extra $1,000 USD to burn and without any research or pre-planning I purchased 35 LED bulbs to replace my incandescent and CFL bulbs. I was way tired of continually replacing a couple CFLs time and time again and the 25,000-50,000 hours of lifetime sparked my interest and put a $1K hole in my wallet.

Home Energy and the Fracking Dividend

Most of us will agree that it’s technically feasible to build homes that consume dramatically less energy than today’s typical home. And in most locations we can build a home that draws net zero energy from the utility. But it’s economics that makes us hesitate. Specifically, it’s the value of those energy savings. Can the additional investment be offset by anticipated reductions in energy costs? It’s the same thing for retrofits of existing homes: Do the lower energy bills justify the…

Heat Pumps and Record Snowfall

      I remember a rash of nuisance service calls rolling in on weekends like this, the snowfall being the key part.  It is amazing how well prepared a Heat Pump is for cold weather, with safeties, defrost controls, and supplemental heat (in most).  Unfortunately, they do not come with windshield wipers to keep the condensers clear of snow, and snow will decrease the airflow across the condenser to a breaking…
