Lowe calls for more renewable energy use.


An environmental scientist says Queensland should use more renewable energy sources to generate electricity.
A two-day climate change summit has begun at Parliament House in Brisbane this morning.
It is the third summit at Parliament this year, where previous meetings have covered road safety and obesity.
Keynote speaker Professor Ian Lowe, from Griffith University, says other states have more ambitious targets than Queensland.
"I'm going to argue today that we in Queensland should be setting strong targets for renewables, like 20 per cent of our electricity by 2020, and half of it by 2050," Prof Lowe said.
"They're entirely achievable, and if you look around the world Sweden now gets a third of its energy from renewables, Norway half, Iceland two-thirds - it's simply a matter of political will."
