Solar/wind is cheap as long as you still have something else to back it up when it fails. Battery is cheap and profitable as long as you're only building a coup

Solar/wind is cheap as long as you still have something else to back it up when it fails. Battery is cheap and profitable as long as you're only building a couple minutes of capacity to play grid stabilizer/arbitrage games. It's similar to the problem in privatized health insurance. It's very cheap and profitable to insure young healthy people. Especially when you can dump the responsibility of all the old and sick people on the government. Of course investors invest in these things - they give quick, high returns on investment. That doesn't mean they're good for long-term stability.
