If you need to know something about energy-efficient lighting and the thought of logging on to a search engine and trolling through copious amounts of websites and articles elicits an involuntary groan, the UNH Cooperative Extension may have what you're looking for - and Energy Answers hotline, 877-398-4769. The hotline expands the capacity of the program's toll-free Info Line in Manchester by staffing the existing lines with volunteers trained to answer energy-related questions or refer callers to experts and other outside resources who can. The line is open Monday through Friday from 9 a.m. to 2 p.m.
