wrong. many of the energy options that are claimed to be extremely cheap and that they lean on - wind and solar particularly - aren't as cheap as they're made out to be. e.g. people love to cite Lazard's LCOE projections, which undershoot actual cost, overshoot production, and undershoot wear and tear (esp. on solar). storage numbers also often suck. frankly, hydrocarbons are probably a better option to synthesize and store than something like lithium-ion batteries. and storage becomes a much bigger concern if one considers running a grid primarily on inconsistent renewables rather than using them as auxiliary power sources. plus your magical all-green grid still needs gas peakers most likely unless you massively overbuild that storage and generation.

Lithium ion batteries have an efficiency of around 99%. They are also not the only form of energy storage system or battery technology used for ESS. The most efficient fossil fuel power plants (combined cycle plants that burn natural gas to power a generator driven by a turbine, and then use the heat from the exhaust to generate steam in a second turbine) have an efficiency of about 60%. That doesn't even begin to address the inefficiency in "synthesizing" "hydrocarbons." Electrolysis, for example, is less than 95%. If you have such a fundamental ignorance then you are not remotely qualified to be making comments like "wind and solar are more expensive than they're made out to be!" You must know better than all those silly grid and solar/wind farm operators! You should ring them up and tell them how stupid they are to be using solar and wind, how they have no idea what it's actually costing them! And no, green power is not "unreliable." Hilariously, during the massive Texas blackouts during the ice storms, wind and solar were just about the only power sources still working... That German power system you alt-righters love to shriek about for being stupid for going green? They have one fifth the outage rate the US does. As they massively increased their green power sources, their grid reliability went up. https://e360.yale.edu/features/three-myths-about-renewable-energy-and-the-grid-debunked https://e360.yale.edu/features/three-myths-about-renewable-e... Several countries in Europe have periods where their grids are entirely powered by renewables. But suuuuure, "magical green power" is unreliable.

  you are the one guilty of either fundamental misunderstandings or willful ignorance. producing enough lithium-ion storage would be insanely expensive at anything even close to current prices. and lithium-ion batteries suffer from wear, more or less depending on the chemistry, but all do. you are wrong. green power is unreliable in the sense that it doesn’t produce constant load. i am asking you nicely to open one book and learn about the duck curve, then go analyze what storage at grid scale would actually cost. you’re rephrasing what i said in an aggro manner: running temporarily off renewables doesn’t change the need for storage and peakers. all the countries i know of who’ve done that have much, much lower energy consumption and are much smaller than America. not sure where you got this alt-right allegation, but please go learn some more about this topic. in the mean time, know your place and mind your manners.
