If You Sell Electricity, You Should Be Worried

Any way you look at it, residential electricity use in America is falling. Recent data from the Energy Information Administration show that electricity use fell 3% in total and 7% when calculated per person in the last five years. This is a lot of electricity, corresponding to a 300 kWh per year reduction per person, or about one refrigerator per home. The decline also appears to be widespread; for example, residential electricity consumption fell in 48 out of 50 states between 2010 and 2015…

Will ZNE Transform Energy Efficiency?

There is a lot of conversation these days about making buildings Zero Net Energy (ZNE). The basic idea is that a ZNE house or building produces as much energy as it uses in a year. Early adopters have been interested in ZNE building for years, but its only recently that…

Micro-housing for Veterans

“‘Never leave someone behind.’

That was our pledge in the military and in my time as a police officer. When you retire or move on, that doesn’t go away.”

In 2014, Donnie Davis got a phone call about a local campground in southern New Jersey that was up for sale. A crazy idea popped into his head. It would require a lot of money and hard work, but it had the potential to help countless neighbors and families. Donnie decided to take a leap of faith — and change the lives of his…

It’s Time to Stop Using Fire in Our Homes

At some point in time man gained control over fire. Fire was very useful: it could be used to cook food, provide light, and its heat allowed us to survive in hostile environments.

Thousands of years later, some things haven’t changed much. Whether we have a natural gas or propane furnace or (in some parts of…

Energy loss through fireplace

There are a lot of different kinds of fireplaces out there.  We all know the old wood burning type, but the newer gas fireplaces are more convenient and cleaner burning.  

I have customers that are complaining about the cold air coming in from the gas fireplace.  I have done a lot of research for my business, with some confusing information about the construction of gas fireplaces.  There seems to be a trend of venting the gas fireplace, directly outside, behind the fireplace.  I have…

Good Intentions, Poor Results

The energy efficiency industry in California is tangled with regulation.

Without a doubt, there are many policies that have been successful. California’s strict building codes have reduced energy use per capita and are responsible for eliminating the need to build 15-20 new power plants over the last 30 years. This is a great result and job well done.

But there are also plenty of cases where…

Angry Air!

John Tooley said, “Air is like crooked rivers, crooked people, teenagers, and cheap labor.  It always seeks the path of least resistance.”  He didn’t say that Angry air is Noisy air.   Air doesn’t like being forced through corrugated, flexible ducting, pushed around corners, and made to force open dampers.  It resists being made to perform in a way that it doesn’t want to.  It takes more and more force as the resistance increases.  Air is just fine when you just let it move at will.  It can…

EPCs - Do You Know The Law?

Whether you are a property owner, landlord, tenant, contractor, or otherwise, it is essential to know the current and proposed laws surrounding energy performance certificates, or EPCs.

An EPC is essentially a guide to how efficiently a property uses energy, the cost of running the property, and recommendations on how to potentially improve the energy efficiency of the property.

An EPC is…

The Climate Accord

 

So first I would like to point out that our leaving the Climate Accord was foolish. It was a non binding agreement to begin with. We could chose or chose not to contribute as we saw fit. It was based on self policing. Leaving it does not really make sense and simply diminishes our leadership role globally in an arena we are quite capable of leading.

 Neither Kyoto nor Paris ever had a chance of being ratified by the…
