By Jerry Yudelson Yudelson Associates –  More people are going green each year, and there is nothing that will stop this trend. In fact, it is accelerating each year. As a result, we expect to see considerable interest in green products that promote water conservation and energy efficiency, including fixtures and appliances, as well as energy-efficient windows and doors, certified wood products (either FSC or SFI), and recycled-content materials.Many individual homes and businesses are investing in new resource-efficient technologies and green operational practices, and cities are developing certification systems to reward this behavior. My consulting company, Yudelson Associates, is a good example. In December 2010, we were certified by the city of Tucson, Az., as a green business because of our operational practices, including solar electric and thermal systems, water conserving fixtures and rainwater harvesting, waste recycling, and environmentally preferable purchasing. These are all measures that you will begin to see adopted in greater numbers by many of the end-users served by you and your direct customers.
