This week a major winter storm ripped across most of the eastern United States.
It caused major electrical blackouts and endangered the lives of millions of Americans.
Texas, normally home to mild to mid winters saw temperatures dip below freezing and major snowstorms hit most of the state.
Demand for heat and power soared, while the grid lagged behind. This sparked major rolling electrical blackouts across the state.
Texans without power were forced to warm up in cars, or run propane heaters in their houses.
As the grid failed, power prices to surged from $23 per MWh to over $7,400 in a matter of days.
