5 Common Misconceptions about Solar Energy

As an outspoken supporter of the necessity to move toward green and reusable energy I often find myself debating individuals critical of such technologies, particularly solar energy. The level of misinformation and on occasion downright ignorance leveled toward the solar community is baffling to say the least. With so much misinformation running rampant amongst the solar skeptics amongst the world I found it prudent to clear up some of the most common distorted oppositions to an industry the…

The Fast-Changing World of Saving Energy

In reviewing the content of Home Energy's January/February issue, I was struck by how rapidly the energy-saving business is changing. In the issue, we cover the come-from-nowhere explosion in LEDs. Another article about energy-efficient homes in Germany describes the rapid shift to near zero energy homes. That article also reminds us why it is getting risky to ignore activities on what used to be the…

Blower Door DG-700 Meter drift

I left batteries in the DG700 for 2 years, 2 of them 6 corroded. Manufacturer said that the meter has to be recalibrated. I asked why? Because there is a drift of up to 1% caused by pressure sensor. The question is how significant is this amount. Say we have Blower Door air flow 1650 CFM. So 1% = 16.5 CFM or readout will be between 1666 and 1644. Is the difference practically significant?

Important Facts about Solar Energy

“I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.” - Thomas Alva Edison.
