THE Holden Volt was the big drawcard at The Megawatt Fair on Saturday.
The long-range electric car was on display in Bendigo as part of the event, ahead of its official launch later this year.
The Goldfields SolarHub event also featured solar panels, LED lighting, an electric bicycle collection and an electric motorbike.
There was a technology tent, a kids zone with face-painting, hoola-hooping, candle-making and plenty of people on hand to give advice about sustainable energy.
The Megawatt Fair was held at Big Hill Vineyard to celebrate more than 570 solar installations by Goldfields SolarHub in Bendigo.
More than 1000 people attended the event, according to one of the event organisers, Ian McBurney.
"We had a steady flow all day," he said.
"People had technical questions about the Holden Volt and there were a whole lot of people coming through and looking for various things.
"We all get too serious about energy and sustainability sometimes, it is serious, but it's good to do something fun like this, too."
Nadine Ellery from Bendigo said she'd decided to take a look around the fair with her father who was interested in solar cars.
"I'm enjoying it," she said.
"It's nice to have a bit of music and food to fill it out.
"I've had a bit of a chat with some of the architects and I've also learnt about small business-related sustainability."
