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...

    Except the US has a *lot* of land, a hefty chunk of which gets a lot of sun and has little development, yet is still relatively close to major metropolitan areas (namely Los Angeles, but add in Las Vegas, Phoenix, etc. for good measure). Additionally, solar (and to an extent wind) can be deployed on very small scales, making decentralized power generation feasible in certain areas (currently not legal with nuclear, though an RTG might do well in Alaska...).

    I'm all for nuclear as a source of clean energy, but having multiple sources of clean/renewable energy is a Good Thing.

    The issue with Wind and Solar is that they require large areas to be installed on

    Why is that an "issue"? Do you actually believe that we are running out of land?

    Windfarms can have co-use as grazing or cropland

    Solar panels can go on rooftops, over parking lots, or in deserts.

    This is why hydraulic fracturing has been attacked in order to drive the prices back up.

    No. Fracking has been attacked because it runs the risk of poisoning the groundwater.

    Somehow I doubt the cost of maintaining a wind farm is a major overhead compared to other forms of power generation especially when the cost of controlling emissions / pollutants and decommissioning is taken into account.
