A storm is brewing.
There are some huge issues at stake – and many of them are being ignored.
The Victorian government is aiming to boost renewable energy to 40%.

Disruptive technology, Ming Dynasty-style.
In pulling out of the Paris climate agreement, Donald Trump has turned his back not just on the world but on the low-carbon economy. He should pay heed to a very apt lesson from China's history.
This array in Indiana is one of a growing number of “community solar gardens” in the US.
Without help, lower-income people could miss out on the clean energy revolution – hence the arrival of community projects aiming to boost access to solar panels, batteries and other green technology.
ARENA part-funded the Broken Hill solar plant in New South Wales, which opened this year.
The Australian Renewable Energy Agency is facing a $1.3 billion budget chop as part of the federal government's savings measures. But sacrifice the lead agency for green energy development
Across Africa the potential is ripe for a clean energy revolution that upsets and leapfrogs the old fossil-fuel order.

Both electric cars and renewable energy stand to gain significantly from cheaper storage.
Battery prices are falling faster than anyone expected: that's good news for solar power and electric cars.
Wind farms like this one probably wouldn’t exist if the government didn’t provide a hefty subsidy.
Congress passed the wind production tax credit (PTC) more than two decades ago to spur development in an industry still in its infancy. The wind sector has since matured into adulthood, prompting thousands…
Electricity from wood? We have the power.
When we think of renewable energy, it’s easy to picture spinning wind turbines or rooftop solar panels. But what about bioenergy? While wind and solar are now well established – in South Australia wind…
Battery costs can make up a quarter of the cost of an electric car such as this Tesla Model S.
At the heart of the current debate around energy is the question of storage. In cars, how to build batteries that run for hundreds of kilometres; in electricity, storing energy from solar panels for when…
