US Wind Capacity Surpasses Hydro, Overall Generation To Follow (arstechnica.com)

An anonymous reader quotes a report from Ars Technica: Wind power is now the largest source of renewable energy generating capacity, passing hydroelectric power in 2016. And since the two sources produce electricity at nearly the same rate, we'll soon see wind surpass hydro in terms of electricity produced. Wind power capacity has been growing at an astonishing pace (as shown in the graph above), and 2016 was no exception. As companies rushed to take advantage of tax incentives for renewable power, the U.S. saw 8.7 Gigawatts of new wind capacity installed in 2016. That's the most since 2012, the last time tax incentives were scheduled to expire. This has pushed the U.S.' total wind capacity to over 81 GW, edging it past hydroelectric, which has remained relatively stable at roughly 80 GW. Note that this is only capacity; since generators can't be run non-stop, they only generate a fraction of the electricity that their capacity suggests is possible. That fraction, called a capacity factor, has been in the area of 34 percent for U.S. wind, lower than most traditional sources of electricity. But hydropower's capacity factor isn't that much better, typically sitting at 37-38 percent. As a result, wind won't need to grow much to consistently exceed hydro.

    Then we'll be left with a lot of wind plants, I wonder how they'll be able to afford to provide fuel for them...

    Also in each ISO there still has to be spinning generation to maintain voltage and VAR support.

    No, it's just a file when it's an ISO. It doesn't start spinning until you burn it to the CD.
