Reliance on Wind Power leads to Blackouts

I have blogged about this before and no doubt will gaian, but in this case take a read of Watts Up With That as they write about Texas's recent blackouts:

'When the wind is light, the turbine blades do not turn. And, the coldest nights usually occur with snow cover and light winds. The 9pm weather map for the region is below. The red number at upper right is the current temperature and they are well below zero deep into New Mexico and parts of Kansas and Colorado, so regional power use is high. Springfield, CO was already -15°F. Temperatures are in the single digits and teens over most Texas with very light winds in the areas where the turbines are located.'

Reliance on wind power is ridiculous and I fail to understand why supposedly intelligent people cannot see that.
