A winter storm in Texas brought record low temperatures, snow and rolling blackouts across the state.

Millions of Texans are still without power, and some people have questioned why a state that produces the most power in the US is unable to keep the lights on.

Roughly 3 million people in Texas have had to deal with outages since Monday as power generators and natural gas pipes froze, crippling the state's production capabilities.

This led the Electric Reliability Council of Texas (ERCOT), which manages the state's power grid, to administer rolling blackouts to avoid a grid failure. .

Almost 50% of power generated by Texas comes from natural gas, with the other half divided among coal, wind, nuclear and solar.

The significant drop in power generated led to rolling blackouts across the state as ERCOT tried to keep a balance between the supply and demand in order to prevent a "catastrophic" blackout.

"Our wind and solar got shut down, and they are collectively 10% of our power grid, and that thrust Texas into a situation where it was lacking power in a statewide basis," he told Hannity

According to ERCOT officials, however, the majority of power lost came from thermal energy, which is primarily made up of natural gas, and not wind or solar energy.
