  • I work for a private solar developer in NYS, and I can see that the state regulators are either asleep at the wheel or intentionally complacent with allowing private utilities to let our electric infrastructure rot so they can keep collecting profits off of ratepayers. We have some of the worst utilities in the country and state is currently suppressing a grassroots effort to oust RG&E, who is the worst of the worst. In general though their refusal to modernize their grid is grinding the goal of 70% renewable by 2030 to a quick halt.

    I had really hoped that getting NYPA behind the building of renewables would make them a heavyweight that could take the utilities to task for their failures, it’s infuriating that they’ve fallen to more regulatory capture.


  • I’m an engineer who designs solar array for a living, here’s how the math breaks down in fairly typical round numbers.

    The all-in cost is around $2-3k per kilowatt (thats equipment, installation, permitting, utility approvals, etc), so a 5kW system (pretty typical residential size) would cost $10-15k. Each kilowatt produces about 1000-1500 kWh every year (depending on your latitude and how much sun your roof gets), so if your electric company charges you $0.10 per kWh, that 5kW system will generate $500-750 worth of energy annually. Without incentives it would pay itself off in 20 or 30 years, but if your state has good solar incentives that can be much shorter, if you pay a lot more for electricity it pays itself off sooner as well.


  • Most places where this can be done, it is already being done. The low hanging fruit for pumped hydro was all picked decades ago, and at great cost to the ecosystems it destroyed in the process - turns out that drowning thousands of acres in massive man-made lakes had a bit of an impact on the plants and animals that lived there.

    Not saying that the benefits weren’t worth the cost, that’s a whole different debate. But there’s little to no opportunity to scale this energy storage tech beyond it’s current footprint.







  • As others have mentioned, you can invest in the stock market within your 401k, though your options can sometimes be limited or saddled with high fees depending on what broker the 401k is through.

    If yours is through a shitty broker then you might be better served by opening an individual retirement account (IRA), likely a Roth IRA given the limited info you’ve shared. You can open one with a broker of your choice, so go with one of the better ones like vanguard or fidelity. Using tax advantaged retirement accounts will always beat saving your retirement money in a non-tax advantaged one, all else being equal.

    Edit to echo the flowchart from one of the other comments: https://imgur.com/u0ocDRI

    This is the core of sound personal finance strategy in purified form. Great resource!


  • Really buying into the corporate propoganda here aren’t you? These used to be great paying jobs, but the average auto workers salary has eroded just like every other industry and is less than $40k these days, even if you arbitrarily exclude non-union auto workers it’s still barely $50k. Even those non-union workers will benefit from industry wages increasing with this new contract.

    Also, this contract will be a 4 year agreement through 2027, and auto workers haven’t seen a raise since 2019. If you considered the 46% they’re asking for as an annual raise over that time period 2019-2027 it would only be a 5.75% annual raise.

    And we haven’t even talked about the inflation since 2019 which has already eroded their pay by 20%, plus whatever additional inflation through the next 4 years will do. If inflation doesn’t cool down through that period this 46% may barely maintain their current wages.

    I burst out laughing while reading this article, it’s laughably bad, written by someone who doesn’t have the slightest understanding of the content matter.

    Virtually all existing communication mediums are light based, since “Light” is a term that covers electromagnetic waves spanning a range from radio waves, all the way up to xrays, with visible light getting a small part of that range in the middle.

    With all light there is a tradeoff where higher frequency light can carry more information at the cost of lower penetration. It’s why your 5Ghz wifi is faster than your 2.4Ghz wifi but the 5Ghz doesn’t reach as far in your house

    Visible light is in the 400-800Thz (Terahertz), so it’s orders of magnitude better for transmitting a lot of data but since it’s blocked by most materials it works better if you use something to channel it, like a glass tube. Which is why visible light is already used extensively as the backbone of the internet, aka fiber optic cable. (to be completely accurate, most fiber optics use near visible infrared light, just below the visible spectrum, since it doesn’t scatter in glass as easily)

    The new communication standard referenced is nothing ground breaking, it’s just a standard for any niche application which can make use of it. It’s not a new technology, and if it was better than existing methods we would already be using it.
