The residents of the house where the posters were erected notified the police and Mr Pennings said, while he took the threat seriously, he would not let it stop his resolve. "I always take these situations seriously," he said in a statement. "This threat of violence against me and sabotage of our campaign materials will only strengthen our resolve."

The threat came on the eve of a Greens announcement to use council buildings and spaces used to create energy if Mr Pennings tilt at office is successful. Greens senator Larissa Waters will announce on Monday the party's local council plans to install solar panels upon council owned buildings and to take it a step further and use solar panels to generate shade in public parks and on walking and cycling tracks. Mr Pennings said it was a great way to reduce council's power bills and provide shade for the public. "It's a double whammy," he said. "We have a very hot climate and people enjoy shade."

Mr Pennings said the plan did not involve putting solar panels on existing shading but instead making council land available for tender for companies to install new shading. "An example might be the car park of a public pool where the solar panels can either feed back into the grid or support the electricity needs of the pool itself." He cited the new car park at Buranda, where utilising solar panels for shading was working well, and a system that could be replicated in the Brisbane City Council area. "With the car park at Buranda, the feedback we got was phenomenal," he said. "People love the idea. It's saving money and supporting new and emerging businesses."

Mr Pennings said using existing council infrastructure to install solar panels would also help the council to save money. "Brisbane City Council is a huge area," he said. "A site with the right aspect for solar can do very well." Brisbane City Council already purchased 100 per cent green power for the energy used, but Mr Pennings said this could take things a step further. Mr Pennings has also thrown his support behind independent mayoral candidate Jim Eldridge's plan to ban alcohol advertising on council busses.

"We have had a lot of feedback in regards to wrap around advertising on buses," he said. "A lot of people, particularly at night, are having a hard time seeing their stop. "There's enough things discouraging people from using public transport in regards to cost and frequency." He said Mr Eldridge's plan to ban the advertising of alcohol was a positive step. "It is similar to cigarette advertising being banned," he said.

"I don't think it is too long before we will see a ban alcohol advertising as well." For independent news coverage, be sure to follow our Facebook feed.
