"The future health of Australians depends to a large degree on having a healthy environment," said AMA Public Health Committee Spokesperson, Dr Alex Markwell.
"Renewable energy is a key solution to the climate change problem and this survey shows the majority of Australians are prepared to pay for it."
The survey of 1,200 adults, conducted in September, found 64 per cent would pay an extra $3 per week on their electricity bill to help meet a renewable energy target of 25 per cent by 2020.
"If we continue to allow greenhouse emissions to increase, Australia will see more droughts and heat waves, a rise in heat related illnesses and the spread southward of the dengue transmission zone," said ACF Executive Director Don Henry.
"In contrast, early action to reduce greenhouse pollution, including a strong mandatory renewable energy target, would have major health benefits," he said.
