Each year, EcoHome’s sister publication Building Products assembles its annual Top 100 list, a ranking of the products that readers of Building Products, Custom Home, Builder, and Remodeling requested more information about by mailing in reader service cards found in each issue. As in year’s past, the Top 100 doesn’t contain many commodities, but rather those wares that are less familiar, new, or trendy. What was different, however, was the sheer number of green products—including solar panels, tankless water heaters, and resource-efficient materials—that came out on top. More than half of this year’s honorees offer properties that contribute to eco-friendly, durable, comfortable, and/or healthy homes.
Here are the 53 green products from this year’s Top 100.
#1 Endurance Wind Power. The Endurance S-250 wind turbine can be connected directly to the power grid without the need for an inverter. It has a power rating of 5 kWh and can match the energy requirements of average U.S. households that consume up to 18,000 kWh per year, the company says.
