John M. Broder writes about a new U.S. Department of Energy report released July 11th that details the vulnerability of the nation's entire energy system to climate change effects - from droughts, intense storms, rising seas, lower river levels...
Simply put, every source of power will be affected. Just as the climate will cause more strains placed on the power sector, e.g., from rising heat in West, the sector will be subject to numerous disruptions - the perfect storm.
Every corner of the country’s energy infrastructure — oil wells, hydroelectric dams, nuclear power plants — will be stressed in coming years by more intense storms, rising seas, higher temperatures and more frequent droughts.
We don't have to wait, writes Broder. It's happening now.
The effects are already being felt, the report says. Power plants are shutting down or reducing output because of a shortage of cooling water. Barges carrying coal and oil are being delayed by low water levels in major waterways. Floods and storm surges are inundating ports, refineries, pipelines and rail yards. Powerful windstorms and raging wildfires are felling transformers and transmission lines.
Every region in the United States will be affected. In the West, "(t)he Energy Department’s Argonne National Laboratory found that air conditioning demand will require 34 gigawatts of new electricity generating capacity by 2050, equivalent to the construction of 100 power plants. The cost to consumers will exceed $40 billion, the lab said."
In the Southwest, climate-caused water shortages will affect the cooling necessary for fossil fuel power plants as well as the production of hydroelectric power.
The report was overseen by Jonathan Pershing, deputy assistant secretary for climate change policy and technology. He said that "cities, states and the federal government must take steps to adapt and improve their resiliency in the face of more wicked weather."
The 82-page report (PDF) is composed of four chapters (in addition to executive summary and conclusion):
- Increasing Temperatures
- Decreasing Water Availability
- Increasing Storms, Flooding, and Sea Level Rise
- Adaptation Actions and Major Opportunities
Indiana Once Again Considering Ban on Dedicated Transit Lanes
The proposed legislation would impact the construction of planned IndyGo Blue Line, the third phase of the city’s bus rapid transit system.
LA Freeway Ramp ‘Quietly Canceled’
A 2018 lawsuit forced Metro and Caltrans to do full environmental reviews of the project, leading to its cancellation.
LA’s ‘Spongy’ Infrastructure Captured Almost 9 Billion Gallons of Water
The city is turning away from stormwater management practices that shuttle water to the ocean, building infrastructure that collects and directs it underground instead.
Micromobility Operators Call for Better Links to Transit
For shared mobility to succeed, systems must tap into the connectivity and funding potential offered by closer collaboration with public transit.
Retaining Transit Workers Is About More Than Wages
An analysis of California transit employees found a high rate of burnout among operators who face unpredictable work schedules, high housing costs, and occasional violence.
California's Stormwater Potential
A new study reveals that if California could collect and treat more stormwater in cities, it could provide enough water to supply a quarter of the state’s urban population.
