Australian Greens leader Bob Brown joined Greens MP Adam Bandt in Melbourne's Federation Square today to unveil a giant Greens billboard and information blitz on the clean energy plan.

The billboard dominated by a newspaper headline "Greens secure billions for renewable energy". The ad also riffs off the Greens election slogan "your vote is powerful" emphasising the key role Melbourne voters played in getting the government moving on the clean energy plan.

Hundreds of Greens supporters and volunteers will also fan out over the Melbourne electorate at train stations, tram stops and shopping strips distributing information based on the ad.

"In Melbourne, climate change was the number one issue during the federal election campaign" Mr Bandt said.

"When Jullia Gillard asked for my vote to help her form government, the Greens' first condition was for a price on pollution."

"Instead of waiting for 2013 or a community assembly, thanks to the voters of Melbourne we have today kick-started Australia's move to a clean energy economy."

"We have delivered billions for renewable energy and looked after low-income earners. The voters of Melbourne should be very proud."

"This ad campaign and information blitz by our supporters will remind the people of Melbourne that their vote is powerful."
