For years, net-zero campaigners have refused to admit that wind and solar cannot keep the lights on during the evening and morning peaks. Climate realists using the phrase "when the sun doesn't shine and the wind doesn't blow" have been mocked for years.
That ridicule has now gone down the memory hole and net-zero advocates are now acknowledging the truth of that statement by introducing a policy called "firming." This involves the process of storing electricity generated during the day for use during peak demand in the evening and morning—exactly what I've been saying for 15 years.
The issue here is the cost: batteries and pumped hydro costs a fortune and batteries only last 10 to 15 years before needing replacement. There’s also an energy loss to consider—batteries lose about 10% of the energy put into them and another 10% on the way out, while pumped hydro uses more electricity to pump water uphill than it generates on the way down.
I asked the Minister about the cost of "firming," and her answer was quite embarrassing — she didn’t know. It's likely to exceed $100 billion.
