I thought I would give some perspective on some misinformation that circulates out there about renewables.
Texas Freeze Feb. 2021 - ERCOT the Texas power grid failed during the days long hard freeze, which froze power plants and wind turbines. This one created misinformation (if not down right lies) on both the conservative and liberal fronts.
Truth - nearly 40% of the power provided through ERCOT is not fueled by hydrocarbons, but by wind, solar and nuclear. As a matter of fact Texas has the highest % of it's power generated by non-HCs in the country.
--- Abbot the idiot Republican governor of Texas blamed the Wind Turbines freezing on the failure of the grid, when in reality the Natural Gas power plants froze too. The whole system was unprepared for the multiday sub 10 degree F temperatures. But again Abbot is an idiot and a disgrace - IMO.
--- Liberals in turn blamed the failure on the reliance on HCs, ignoring the frozen wind turbines and Texas' extremely high % of renewables.
Liberal Lie - Renewable sources are much less susceptible to adverse weather than HC fueled power stations. They point to refineries going down (mostly after Katrina) during hurricanes as evidence, and of course the Texas Power grid. Firstly, refineries don't produce power so that argument is apples vs. oranges and while the LA refineries were cleaning up (they were down 2-4 weeks), the rest of the US refineries picked up the slack.
--- Frankly this is one of the dumbest things I've seen recently, and there is no evidence to support, but multitudes to refute it.
- https://www.energy.gov/eere/water/articles/study-finds-hydropower-provides-reliable-electricity-even-during-historic - while this report (2021) says even in drought conditions the region can balance power load, the level of drought had become so severe, that two large hydroelectric dams were projected to shut down in 2024, but that was before the massive flooding and rains and snows of Winter 2023, which were not expected. This is where Lake Meade was before the hugely unexpected Winter. https://www.cnn.com/2022/12/30/us/colorado-river-lake-mead-drought-2023-climate/index.html But nature saved us and it's a good thing. But it just goes to show that renewables are NOT nearly as sustainable as HC power. They're both needed to supplement each other and provide reliable energy.
- Solar Farm nearly destroyed by hail - https://www.renewableenergyworld.com/solar/solar-farm-pelted-by-giant-hail-as-severe-storm-ripped-through-nebraska/#gref - there's no repairing this. The panels have to be replaced, which will be time consuming and expensive. Hope they were insured.
- St Thomas solar farm destroyed 2017 by hurricane Irma - 4.5 years till operational again - https://stthomassource.com/content/2021/04/28/st-thomas-solar-farm-projected-to-be-back-online-before-years-end/
I could go on and on with the last point. There are multitudes of examples.
Interesting stuff. The natural disaster factor on solar farms including hail is a problem I have never considered. Unless every panel had the means of moving and being able to prevent destruction it is a real risk. And would make me hesitant of any massive investments. Hopefully they can continue to improve solar cell efficiency and we see them on every rooftop.
Idk how much of it is marketing and bs and how much is truth. But if they can produce hydrogen out of untreated ocean water, transport it through pipelines, store it, and even get bonus byproducts that can be utilized elsewhere. Idk how that is not the future. The company shyp says they can 3d print membrane that will do it. And as far as renewables go, making fuel out of ocean water and taking it another level and making the combustion of hydrogen produce clean water sounds really promising.
