Changing climate poses threat to power plants, US report says

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 .

"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 to prepare the country for its effects."

The report calls on federal, state and local governments to more urgently prepare - particularly coal, natural gas and - 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 have increased 1.5 degrees since 1900. More than 130 costing $1 billion or more in damage have occurred since 1980.

It says that 2012 was the second most expensive year for weather and climate disasters, with $115 billion in damage from Hurricane Sandy and extended drought.

Higher , costing consumers $45 billion, will require an additional 34 of new 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.

Greenpeace USA spokesman Robert Gardner said the administration's focus should primarily be transitioning to wind and solar technology, not relying on fossil fuels and nuclear energy.

"The question is why the Department of Energy is really focusing on continuing the problem which has caused this tidal wave of global warming," said Gardner.

Benjamin Cole of the American Energy Alliance, which lobbies for oil and natural gas, said that climate predictions should not be used to justify the "sweeping changes" of Obama's energy proposals, and that alternative energy has not yet lived up to promises.

"We can't continue to dole out money we don't have," for alternative energy, he said.
