The response to Tathra's Eternity Festival has been so overwhelming positive there are plans to turn it into an annual event that will raise funds to make the town hit a target of 100 per cent renewable energy by 2030.
The 500 tickets to Sunday's festival, which will host five bands for five hours for $5, sold out in two weeks.
Clean Energy for Eternity founder Matthew Nott said the festival is a fundraiser for Tathra's AFL and cricket clubs, aiming to add 5kilowatts of solar panels to the 12kilowatt solar system already installed at Lawrence Park.
Also, money will be raised to set up solar panels on the Rocky Hall NSW Rural Fire Service's fire shed.
Due to the response, Dr Nott said the Eternity Festival will become a much larger, annual event to raise the money to supply Tathra with 100 per cent renewable energy by 2030.
"So we can show other towns what you can do if you continue to be proactive about solutions to climate change," he said.
He said the target could be achieved with a larger solar installation.
For example, he said the Imagine solar farm at the town's sewerage works is currently providing about one third of the facility's power, but due to the infrastructure already in place it could be expanded with more panels to provide all of the sewerage plant's needs.
Also, he said, if enough community enthusiasm was generated land could be purchased to build a new solar farm on, then funnel its proceeds back to the town.
"Solar is so cheap at the moment you can afford to look at a bigger scale set up," he said.
"We may not get to 100 per cent renewable energy by 2030, but we will give it our best shot and this Eternity Festival is one way to get there."
Dr Nott said while the NSW government had a positive attitude towards the renewable energy sector, the federal government did not have the same vision - but he believed it would have to soon accept the economic benefit of action on climate change.
"It doesn't make long-term economic sense to focus on coal in this country, it's going to become a stranded asset," he said.
"We need to become a renewable energy superpower in Australia, and Tathra is going to show them how to do it."
Anyone heading to the Eternity Festival on Sunday should make sure they bring a chair, as they must be seated due to COVID-19 rules.
Also, do not bring alcohol or food, stay home if you are feeling unwell, and it is a non-smoking event.
