Three components to100% Renewable Energy
Concentrated solar thermal power
Wind power Upgraded electricity grid

Why these three?
• Technology is ready now – no need to wait for new inventions.
• Technology that is not expensive – can afford it.

SolarPhoto voltaics (PV)• Solar panels used on
roofs and large arrays.
Solar thermal• Industrial-scale solar
power that replaces power stations.

• Baseload power – works 24 hours a day.• Dispatchable – can ramp up in minutes to meet
sudden demand surges.

Cost?The Australian Government Treasury estimates cost of
wholesale electricity in 2030.
• Australia will spend $1.3trillion on oil till 2030. Better to invest it in renewables.
