I don’t currently mine, but everything I’ve been reading has roughly 2/3rds of your profit going towards electricity. Regardless, I find it hard to believe CPU mining using JavaScript in a browser is even remotely energy efficient.

At 12c/kwh with a Radeon RX Vega56 consuming 200W and a hashrate of 2000 h/s, mining XMR currently yields has a 61% profit margin; it's 79% ROI if you are getting free power. This is not the most power efficient setup (as I said, there are far, far more efficient cards, especially when run in tandem) but it is the most sought-after card due to density. Regardless, it's exceptionally profitable to mine if you already own the card. JS mining only takes a slight performance hit compared to native, actually; asm.js and others provide very good results since the problem is memory-hard, not computationally bound. It is definitely energy efficient and worth doing if all you care about is ROI vs. marginal utility rates in most American cities (perhaps not some of California). Nicehash built their business model around exactly that, which is the real reason people like libraries like the OP's - it's a distributed way to get people mining, not for the individual person themselves.

  Radeon Vega64 is insane. Sold out everywhere I’ve seen.

    The 64s are occasionally available, the 56s, no shot. Glad I got 7 close to MSRP when I did. There are actually more power efficient alternatives that hash better per dollar assuming that the price of a Vega is $600+, which it easily is. Just requires some heavy lifting.

  In that case, thanks for the correction. I suppose I made my original comment with a lot of assumptions that may be less true than I would have thought.

    No problem, thanks for being open minded. It won't last forever... probably. However, this is a lot different than BTC mining due to memory hardness.
