We’d like to clarify the introductory paragraph on our Requirements for Energy Tax Credits poster insert from the June 2009 issue. The paragraph states that renewables are eligible for tax credits if used in a residence and if placed in service on or before Dec. 31, 2016, and apply to all residences, including principal and secondary residences. However, there is one exception to that rule: fuel cells. A fuel cell generator is only eligible if used in a principal residence. All charts and articles in the June issue have the correct information on fuel cells and renewables. You can find more answers to these kinds of questions at the Energy Star FAQ site.

Our thanks to Dave Maxum of TBH Sterling, in Seattle, for his question on the issue. Please contact us if you notice other issues that we should clarify or correct: remodeling-letters@hanleywood.com.
