| [NOTALOTOFPEOPLEKNOWTHAT] An interesting analysis from David Wojick, originally published by CFACT. |

| #5 Utility batteries are not for storing power. They are for absorbing transient demand spikes or to operate for the 15 minutes for a gas turbine peaking power plant to come online. They reduce the need for spinning standby reserves. |

| #4 Mars Rover Opportunity declared dead February 13, 2019... Renewables depend on environmental conditions the user has little or no control over. |

| #3 touted as being a big step toward making renewables reliable. This is either deep ignorance or pure deception. Or both. |

| #2 There are some mechanical "batteries" that do work. The island of Kauai takes unused power generated via solar during the day to pump water up the mountain. Then releases it at night to power generators. Perfect - no. Useful - yes. |

| #1 The tech is not there, yet. Wojick could have led with that title, which make it suspect at best. I'm reminded of the costs of the first doped ruby lasers and so on. |
