Three students recently won awards in a contest testing their knowledge on energy-efficient and renewable energy technologies and sustainability.

The students include Karina McMahon, a second-grader at Burr Elementary School; Michael McMahon, a sixth-grader at Tomlinson Middle School; and Izzy Roth, an eighth-grader at Roger Ludlowe Middle School.

The pupils are among 44 winners in the eighth annual "eesmarts" contest for students in kindergarten to grade 12, sponsored by the Connecticut Energy Efficiency Fund, Connecticut Light & Power and United Illuminating. Participants answered grade level-specific prompts through various media forms, including poems, songs, news articles, essays, artwork and television commercials, according to a news release from the fund.

The awards ceremony, which took place in the Old Judiciary Room of the Connecticut State Capitol, was attended by Gov. Dannel P. Malloy and Dan Esty, commissioner of the Connecticut Department of Energy and Environmental Protection. Also in attendance were Richard W. Steeves, first vice chairman of the fund's board, and WFSB Channel 3 meteorologist Mark Dixon, the event's master of ceremonies.
