Australia struggling with oversupply of solar power

This is a most excellent place for technology news and articles.
Obama tried to push grid upgrades for years, kept getting shot down. His plans would all be done by now. Throw in the fuel economy requirements of 54.5 mpg requirements for cars and light trucks and we would have seen billions of barrels of oil not being needed. (Lower gas prices as well). Granted it wasn't everything, but it was what we needed to start doing. Now 13, 14 years later after Trump rolled back those fuel efficiency policies as much as he could because it cost manufacturers more money in research, we are much closer to a rock we can't live on and haven't advanced nearly enough. So we voted in Drill Baby Drill to finish off the rock.
Oh no they did that research. The manufacturers complained because the US was the last great dumping ground for old inefficient engines. They put those highly efficient engines in European cars and used the US to empty their warehouses of old engines.
