The Energy Efficiency and Conservation Authority awards recognise organisations, clubs, schools, individuals and businesses which have demonstrated excellence and innovation in energy efficiency or renewable energy.
More than 100 entries were received from which the judges selected finalists for 10 categories. The finalists include local councils, community and charitable trusts, high schools, sports clubs and university students. They come from all around New Zealand, with one even from Antarctica.
Collectively, the 2016 Award entries will save or generate 1.1 petajoules (PJ) of energy, and avoid 120,000 tonnes of greenhouse gas emissions, about one-fifth of the annual emissions of all households in New Zealand.
The award recipients will be announced on May 18.
