As we've been saying, windmills and solar panels need a 100% back-up capacity running and ready to be placed on-line at all times.
A few good nuclear power plants will do the job. We can store the waste on the streets of San Fransissyco, just like the homeless do.
Or, it being Texas, they can fire their power plants with natural gas and petroleum products.
Heck, it's Texas, they could make it a condition to receive welfare for the recipients to go out in to the pastures and collect the cow pies, so long as those people don't eat the chocolate looking ones.
