China knows the smart money is on renewables, and not just because of climate change.
China is pouring money into clean energy - not just to tackle climate change but because these are economically fruitful industries. And as China develops them, the technologies will get cheaper for everyone.
Change is coming for Australia’s energy sector. Time for our leaders to embrace it.
The key drivers for energy in the 21st century are managing climate change, shifting community concerns, and radical technology change.

The UK's first new nuclear power station since the 1990s is coming at the expense of renewable energy and leaving us unnervingly in hock to the Chinese.
Good governance is a foundation for sustainable development under the new goals.
Later this week, world leaders will gather at the United Nations in New York and adopt a set of Sustainable Development Goals to guide global development.

Given existing technologies, expanding access to electricity almost always increases CO2 emissions. There are real trade-offs between addressing poverty and climate change.
Will alternate solar technologies get a boost if solar overall grows?
Hillary Clinton's renewable energy plan is ambitious but, on a technical level, doable. Would it foster more solar technology innovation?
Is the price right for installing solar panels?
Victoria's solar will soon get a mere 5 cents for power they send to the grid. But is that a fair price?
Al Gore brought his climate message back to Australia on Monday.
The reality of climate policy is it's often provincial governments or city councils who are the most ambitious, especially where national governments leave a policy void.
