A Reactor Designed to Burn Through It's Core: Design of a "CANDLE" Nuclear Reactor.

6. Wind

Wind might on average produce twenty or thirty percent of the power in Texas, the United Kingdom, or Iowa, but that average includes long periods in which it does almost nothing. For example, Iowa is part of the Miso, the Midcontinent Independent System Operator, which pools power production from Manitoba right down to Louisiana. Today wind power at times got up to 15% of the power provided there, over 60% of the nameplate capacity of the available wind farms, but for much of the day, wind was only one or two percent. There will always be such lulls, even if, as is often proposed, power could be seemlessly shunted to and from anywhere in the continent. During those lulls, coal and gas are burnt instead.
Here are links to the power production, and also the associated CO2 emissions, of the Miso area, and also of Ontario, which gets much of its power from nuclear reactors. As you can see, emissions from the Miso are about seven times higher than from Ontario. It's a similar story in Europe, where France and Sweden, using nuclear power, have vastly lower emissions than Denmark and Germany, usually touted as renewable energy paragons.
