Three years before Texas experienced the largest forced power outages in American history, President Trump was warned by his own advisors that the US was in danger of experiencing a “catastrophic power outage” that would “outmatch” existing national plans and capabilities. Among the main culprits of this vulnerability, they argued, was an aging electricity grid heavily dependent on oil and natural gas. 

Blackouts that rolled across Texas last week left more than 4 million Americans without power for days at below freezing temperatures. The power outages also left millions without safe drinking water as water pumps and treatment plants went down. Dozens died as a result of the extreme cold.
