If Trump makes good on his rants against wind and solar, it will be countries like China and India that muscle in, the International Energy Agency (IEA) predicted in November.
And Australia? Australia can sell the 21st century world powers the technology to get them to a greener future.

On Tuesday, Australia’s peak science body announced it would be selling solar heliostat technology to China as part of a major new deal.
Working with the Chinese company Thermal Focus, CSIRO’s technology will be used for concentrating solar thermal (CST) electricity generation.
The CSIRO’s heliostat system uses small mirrors to concentrate the sun’s energy and help store energy at low cost.
“In a commercial field, we have thousands of heliostats or mirrors that move across the day and keep the sun focused onto one point on a receiver tower,” Wes Stein, CSIRO’s chief solar energy research scientist, told Mashable.
The resulting high temperatures can then be used to melt and store molten salt in large tanks. The salt’s steam can move a turbine for electricity generation, “whether it’s cloudy, night time, it doesn’t really matter.”
Stein said their technology helps tackle the “critical” issue of green power storage. “As our electricity system moves to renewables, and with the retirement of coal-fired [power] stations, we’re going to need solar energy that’s got storage,” he said.
Thermal Focus will commercialise CSIRO’s heliostat design and the software that controls its positioning.
“CSIRO’s solar thermal technology combined with our manufacturing capability will help expedite and deliver solar thermal as an important source of renewable energy in China,” Wei Zhu from Thermal Focus said in a statement.
While still a heavy user of coal, China has been turning away from the fossil fuel in recent years and upping its clean energy investments.
A September report from CoalSwarm found that there had been a 14 percent drop in the total amount of coal-fired power capacity in early planning stages globally in 2016, of which China accounted for about three-fourths of canceled capacity.
In other words, it’s a bad time to be in the coal business (hear that, Australian government and Adani?)
Stein said China recognises renewable energy storage will become critical.
“Everyone’s installing wind, installing photovoltaics — that’s great. But because they are variable you can’t control when they generate, you need the storage as well, and China’s exactly the same,” he said.
“When they start something, they usually go pretty big pretty quickly.”
