    I'm willing to bet it's option B. Bet someone in management decided it would be best to cheap the fuck out now and then beg forgiveness later, and sell it as increasing security, than ask permission from the beginning.

    They use adiabatic coolers to minimize electrical cost for cooling and maximize cooling capacity. The water isn't directly used as the cooling fluid. It's just used to provide evaporative cooling to boost the efficiency of a conventional refrigeration system. I also suspect that many of them are starting to switch to CO2 based refrigeration systems which heavily benefit from adiabatic gas coolers due to the low critical temp of CO2. Without an adiabatic cooler the efficiency of a CO2 based system starts dropping heavily when the ambient temp gets much above 80F. They could acheive the same results without using water, however their refrigeration systems would need larger gas coolers which would increase their electricity usage.

    No, LCOE is an aggregated sum of all the cash flows, with the proper discount rates applied based on when that cash flow happens, complete with the cost of borrowing (that is, interest) and the changes in prices (that is, inflation). The rates charged to the ratepayers (approved by state PUCs) are going to go up over time, with inflation, but the effect of that on the overall economics will also be blunted by the time value of money and the interest paid on the up-front costs in the meantime. When you have to pay up front for the construction of a power plant, you have to pay interest on those borrowed funds for the entire life cycle, so that steadily increasing prices over time is part of the overall cost modeling.

    Don't get them wrong, they don't do this for you, or even morals. It just affects other interests too much.

    It varies based on local legislation, so in some places paying ransoms is banned but it's by no means universal. It's totally valid to be against paying ransoms wherever possible, but it's not entirely black and white in some situations. For example, what if a hospital gets ransomed? Say they serve an area not served by other facilities, and if they can't get back online quickly people will die? Sounds dramatic, but critical public services get ransomed all the time and there are undeniable real world consequences. Recovery from ransomware can cost significantly more than a ransom payment if you're not prepared. It can also take months to years to recover, especially if you're simultaneously fighting to evict a persistent (annoyed, unpaid) threat actor from your environment. For the record I don't think ransoms should be paid in most scenarios, but I do think there is some nuance to consider here.
