NEW BRITAIN, Conn. (AP) Students in five Connecticut technical high schools have presented findings and recommendations from a year-long investigation of the environmental impact of their school's energy use.

The Connecticut Clean Trades Summit was held Thursday at Central Connecticut State University.

The program introduces construction trade students to careers in the energy industry and the opportunity to make their schools greener.

Participating schools are Norwich, Ella T. Grasso school in Groton, E.C. Goodwin in New Britain, Platt in Milford and Henry Abbott school in Danbury.

During the 2013-2014 school year, teams of 40 to 50 students from each school researched how their school uses energy, assessed water and environmental quality and evaluated recycling efforts. Students proposed energy-saving solutions that will be presented at the meeting.
