A school south of Edmonton is among 10 schools from around the world shortlisted for the World's Best School Prize for Environmental Action contest.
Lacombe Composite High School is the only school in North America to be nominated.
The school has 32 solar panels that produce up to four per cent of the school's electricity, and students also replaced a portable classroom with a greenhouse that operates solely with renewable energy.
Five winners of the contest are to be announced in the fall and a prize of about 322-thousand dollars will be shared.
