Australians overwhelmingly believe that the government should focus on renewable energy over coal-fired power plants, even if such a measures were to cost more, the 2018 Lowy Institute’s annual poll on Australian attitudes has found.

When asked if the government should focus on renewables “even if this means we may need to invest more” or traditional energy “even if this means the environment may suffer to some extent” 84 per cent of respondents opted for renewables. Last year the figure was 81 per cent.

The poll also found that the number of Australians who believe that global warming is a “serious and pressing belief” has climbed to 59 per cent, up five percentage points since last year up and 23 points since 2012. Concern about global warming is now as high as it was back in 2006, the previous peak.

This jump in concern about climate change represents the most significant change in opinion ever found by the poll in its 14 years. It also found Australians consider climate change to be the third most significant national security threat after international terrorism and the North Korean nuclear program.
