NSW voters, including conservative ones, want the state government to step up action on climate change, including boosting renewable energy, two separate polling sets show.

A statewide Essential survey conducted February 6-11 for the Nature Conservation Council of 544 respondents found 51 per cent were more likely to back a party boosting clean energy and 18 per cent less likely. Among those identifying as Liberal or National supporters, the ratio was 43 per cent in favour and a quarter against.

Three separate uComms surveys for Greenpeace, each of more than 600 respondents conducted in marginal seats of Ballina, Coogee, and Penrith, found higher support for renewable energy.

In Penrith, for instance, 60 per cent of Liberal voters said they were more likely to support a party investing in renewables and 30.7 per cent less likely. In Coogee, 52.1 per cent of Liberal voters were more likely to back a party with such policies, and 38.6 per cent against.
