14 August 2013 — A White House report has stated that most grid outages across the US have been caused by extreme weather events.

Since 2002, 58 per cent of outages were caused by extreme weather, the report said.

Seven of the 10 most expensive storms in US history had occurred in the last 10 years, leading to widespread and increased grid outages.

In 2012, there were 11 outages across the US, which cost the country over $1 billion, and reduced economic activity by between $27 billion and $52 billion.

“Severe weather is the number one cause of power outages in the United States and costs the economy billions of dollars a year in lost output and wages, spoiled inventory, delayed production, inconvenience and damage to grid infrastructure,” said the President’s Council of Economic Advisors.

“Grid resilience is increasingly important as climate change increases the frequency and intensity of severe weather.”
