The outrage against Volkswagen (VW) is justified, but let’s not forget that other manufacturers—a lot of manufacturers—have been circumventing energy and emissions tests for decades. Here are a few of my own experiences.
Cadillac was circumventing emissions test procedures 20 years before VW. Cadillac’s engineers faced the same dilemma: How do they comply with emissions control requirements without sacrificing performance? Not surprisingly, they solved…Continue

After the first oil embargo, in 1973, our nation recognized the need to save energy in a coordinated way. It made sense to designate energy utilities to coordinate energy-saving activities in buildings, because nobody had better access to the customer and to key information about the customer. This led to three decades of utility-managed energy conservation programs. Many succeeded. Some did not.
But times change. Today, there’s a new imperative:…Continue
By now you are probably aware of California’s drought. But other states are experiencing droughts—and where there aren’t droughts, there are probably floods. Water and energy consumption are becoming more and more closely connected, and the situation is not likely to improve. Here are some of the ways our clients experience these connections in their homes.…Continue

I must admit that I am still having trouble getting my head around this idea. But the arithmetic is fairly simple: an 80% reduction in carbon emissions simply can’t be achieved without drastic cutbacks in residential natural gas use. In the residential sector, natural gas burned on site is responsible for about one quarter of carbon emissions. We can use carbon-free electricity generated…Continue
The Internet of Things has already improved my everyday life. Devices that communicate with each other deliver new services and features that I appreciate. However, as the Internet of Things expands from a few linked devices to a pervasive network, I fear that aggravation will soon replace appreciation. Are we moving toward the Internet of Annoying Things?
We become aware of the Internet of…Continue

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…Continue

You have probably seen those amazing images of the world at night as observed from space—hundreds of times. Below is one photo, but many others show expanded views of smaller areas. I still marvel at how those necklaces of light show the shapes of our cities. The lights tell stories, too. For example, the Korean peninsula appears surgically sliced at the Demilitarized Zone,…Continue
