75-80% of the Betz limit, that’s my mistake.

I was in the site for work and found the capacity sheets aren’t in the data browser, which surprised me. The information is there, but unfortunately it’s stuck either in the reports or one of the datasheets. The other view I use in that browser is retail price, which can be fascinating but admittedly comes up more for…
Considering that the amount of birds killed by buildings is ecologically insignificant, and the amount killed by wind turbines is an order of magnitude smaller, we should stop talking about both of those things, because they’re not important.
By volume the average taxpayer is probably paying 2-3x as much for fossil fuel leasing subsidies as they are for renewable tax credits. With the end of the crude oil export ban, that also means you’re probably paying a portion of your tax bill to pay for Japan to have gasoline.
Ehhhh...untracked roof panels are going to be forever stuck at around 15% efficiency, and they’re more expensive per square meter of panel than large solar farms. Killing all the rooftop solar subsidies and using the money to build wind and solar elsewhere would be significantly more cost-effective.
Actual cost reductions. Unsubsidized wind is cheaper (in favorable areas) than new gas. That said, the renewal of the production tax credit has spurred wind development, because after subsidies wind is at least $15/MWh cheaper than literally every alternative.
By percentage, Denmark is producing around 100% of local demand through wind. The important distinction is that they are able to do it because of massive transmission trunks to mainland Europe and Scandinavia. Their capacity flexibility is provided by Norwegian hydro and German coal, not their own wind fleet.
The modeling has been done, and the short answer is that if we got 200% of our power from wind there’d be some climactic effects, especially in the middle of the country. That said, the effects would be at least an order of magnitude smaller than what’s modelled for continued CO2 emissions.
You may be confusing efficiency and capacity factor. On average, modern wind turbines are between 70 and 85% efficient at extracting energy from the wind. Due to wind speed thresholds, a turbine may only generate electricity 35-40% of the time (while accurate in some low-wind regions, 20% hasn’t been right on average…
While government subsidy did help spur the technology growth, unsubsidized wind is now (at least in favorably windy areas like the midwest) incrementally cheaper than new gas on a per-MWh basis.
The proposed regulations apply only medium and heavy duty vehicles, but contain a clause which in the process of clarifying this distinction happens to clarify that modifying on-road motor vehicles has been illegal under the CAA for years, and that technically many many race cars are already in violation.
Not nearly as confusing as you think if you have some history looking into these regulations, and I have in the past as a consultant for a major truck/bus company.
I’d be all for seeing the tC rebadged as a Celica, maybe then we can see a GT-S model with some tightened up suspension, breathing mods, and, just maybe, and actual reason to buy it.
They called their high performance division STI, you know, “sexually transmitted infection” to the entire English-speaking world besides the US.
It would be more like your mother pestering you to join the Priory of Sion. Hasids are fundamentalists, and they want to convert all Jews to their interpretation of Judaism.
Unless you’re a secular Jew who lives near a Hasidic community like Chabad. Because while proselytizing is no good, you can try and “save” wayward Jews all you want.
That caused the first major oil price drop, roughly a year ago. This second price drop is caused by a combination of things, but it boils down to a combination of a) China-led demand softness worldwide and b) investor anxiety after oil didn’t start trending upward when the heating season started.
I saw $1.89 in Boston; most of the top-tier stations are around $1.99 or $2.09 though.
