From ETU:

The Electrical Trades Union (ETU) is advocating a report from the US that has modelled the impact of renewable energy targets. ETU national policy officer Lance McCallum said the report prepared by the US National Renewable Energy Laboratory flies in the face of prevailing thinking in Federal Government circles on renewable targets.

“We have seen this government under both its recent leaders act with hesitancy, uncertainty and equivocation around renewable energy. They’ve given the impression, to investors and consumers, that renewables are unstable, expensive and risky. But this report shows that’s far from true.”
