Energy Solutions

With snow gently falling as the holiday season winds down, I find myself reflecting on the New Year and what we might hope for. World peace of course, and solving the poverty conundrum would be great.

But what about energy and the environment? Here are some thoughts:

We live in a world of gadgets and stuff. When it comes to saving energy, we look to high-efficiency light bulbs or dishwashers. Or we use the advanced weatherstripping to seal our windows or add insulation in our attics. And hopefully we’ll look at fuel-economy ratings when shopping for our next car.

Those are important things to be doing — and we should continue paying attention with all of our purchases. But we should also recognize that behavior is a big part of our overall energy consumption.

I’m not a big shopper. I don’t even particularly like getting presents. Our society is just too much about consumption. Nonetheless, as I’ve done on occasion in the past, I’m providing below some Christmas shopping ideas.

Last week I wrote about an innovative foundation insulation material, Foamglas, that we used in our new house in Dummerston. This week I’ll talk about the open-web rafters we’re using to achieve a superinsulated roof.

First, a little background. There are several approaches to creating highly insulated roofs.

In my role with Environmental Building News and our GreenSpec Product Database, I get plenty of opportunities to research and write about innovative building products. That’s one of the really fun aspects of my job.

I attended the GreenBuild Conference and related meetings in San Francisco last week. This is the largest conference and trade show in the green building field, and it is increasingly becoming the national event where large manufacturers roll out new building products.

Described below are a few product highlights from the trade show that caught my eye as I wandered around. I only got through about a quarter of the trade show.

If there’s one thing that we can predict with certainty about fuel costs, it’s that they fluctuate a lot. That wasn’t always the case. The price of electricity, natural gas, propane, and heating oil were remarkably stable for decades — up until the 1970s.

Since then, prices of most fuels have gyrated wildly, driven by political unrest in some parts of the world, periods of greater or lower demand driven by periods of strong economic growth or contraction, resource limitations (real or perceived), and the situation in China and other parts of this increasingly connected world.

By now we’ve all seen the photos of houses buried in sand along the Jersey Shore, burned-out homes in Queens, and submerged subway stations in Manhattan. Those spectacular images were in the first wave of news from Superstorm Sandy last week.

Over the past two weeks I’ve written about wood stoves and pellet heating. This week I’ll focus on another way to burn wood cleanly and efficiently: using a masonry heater.

My wife and I have a sort-of love-hate relationship with our pellet stove. She leans more toward the latter, while I see the benefits outweighing the negatives.

In this column I’ll outline the primary advantages and disadvantages of pellet heating.
