The shooting stars of the Hunter's music scene took time out from the launch of their EP Get Ready last night to encourage people to switch off at 8.30pm on Saturday, March 28.

Singer and guitarist Zac Crawford, 14, said the band and their friends were looking forward to switching off to help the environment.

"I think heaps more people are into it this year," he said.

"It's great that we are going to be saving so much power in an hour. It's really going to help the environment."

Older brother and drummer Ben Crawford, 18, said band members were conscious of their power consumption in the traditionally energy-intensive music industry.

"We try and stay conscious of how many amps we turn on and stuff like that, especially when we get our electricity bill," he said. "Mum always freaks out because we are always rehearsing."

The launch of Powerage's debut EP at Stockland Greenhills last night followed their success at last year's Global Battle of the Bands where they won Australasian Best New Band.
