WASHINGTON – Power plants across the country are at increased risk of temporary shutdown and reduced power generation as temperatures and sea levels continue to rise and water becomes less available, the Department of Energy said Thursday.
By 2030, there will be nearly $1 trillion in energy assets in the Gulf region alone at risk from increasingly costly extreme hurricanes and sea-level rises, according to the Energy Department report on the impact of climate change on energy infrastructure.
“As President Obama said in his speech last month, climate change is happening,” said spokeswoman April Saylor in a statement. “As climate change makes the weather more extreme, we have a moral obligation to prepare the country for its effects.”
The report calls on federal, state and local governments to more urgently prepare critical infrastructure – particularly coal, natural gas and nuclear plants – for the compounded risks posed by floods, storms, wildfires and droughts.
“All of our science goes in one direction: the damages are going to get worse,” said DOE assistant secretary Jonathan Pershing. “It will take dozens of actors from government and private sectors planning what to do and how to make it cost effective.”
The report notes that average temperatures have increased 1.5 degrees since 1900. More than 130 extreme weather events costing $1 billion or more in damage have occurred since 1980.
It says 2012 was the second most expensive year for weather and climate disasters, with $115 billion in damage from Hurricane Sandy and extended drought.
Higher peak electricity, costing consumers $45 billion, will require an additional 34 gigawatts of new power generation capacity in the western United States by 2050. And as infrastructure ages, storm-related power outages are likely to become increasingly frequent, at an annual cost of $20 billion to $50 billion.
“More and more communities are analyzing vulnerabilities and their risks, and developing plans in response to those risks,” said Brian Holland of the International Council for Local Environmental Initiatives. Holland said more state and federal support is needed for communities, who also pursue private funding.
