Drought has engulfed large swaths of the country, threatening parts of the nation’s food and power supply. And it’s getting worse.
More than 80 percent of the continental U.S. is experiencing unusually dry conditions or full-on drought, which is the largest proportion since the National Oceanic and Atmospheric Administration began tracking 20 years ago.
San Diego County is taking a hard and weird hit from Tropical Storm Kay, which generated winds that gusted from 93 mph to 109 mph early Friday in East County and lifted temperatures countywide into the 80s and 90s at the tail end of a long heat wave.
It takes a lot of water to make power.
From spinning turbines to hydraulic fracturing to refining fuel, the flow of water is critical to the flow of electrons and heat. About 40 percent of water withdrawals — water taken out of groundwater or surface sources — in the United States go toward energy production. The large majority of that share is used to cool power plants. In turn, it requires energy to extract, purify, transport, and deliver water.
California Gov. Gavin Newsom, D, has earmarked $5.2 billion in a revised budget proposal released Friday to fund a “strategic electricity reliability reserve” – an up to 5,000 MW resource that the state can tap into when the grid is particularly stressed.
The collapse of the power grid in Texas last week, and the cascading infrastructure failures that resulted from it, are stark examples of why a proactive government matters. A complete evaluation will surely show that, like most accidents and failures, many factors played a role, but it is already easy to see that the avoidance of government regulation contributed to the cold-weather chaos.
Sometime next summer, there’s a decent chance a heat wave will bake the American West, and California’s power grid will again be stretched to its limits. As the sun sets, solar panels will start generating less electricity even as temperatures remain high. Power plants that burn natural gas will fire up as quickly as possible, in a race to keep air conditioners blowing and avert the need for rolling blackouts.
With more than 4 million acres burned this year – shattering a state record – California’s wildfire season came with a wicked ferocity, along with the climate-induced crises of crippling heatwaves and forced power outages.
If you’re in the habit of reading the president’s tweets, you may have noticed a theme the last few weeks: California is a fiery wasteland. He said as much Tuesday, writing that the Golden State is “going to hell.” Trump made the same points in another tweet last week, promising “no more blackouts” or “ridiculous forrest fires” (his typo, not mine) if he’s reelected and clarifying that water rationing is “coming soon.”
On August 14, 2018, Joshua Novacheck, a 30-year-old research engineer for the U.S. National Renewable Energy Laboratory, was presenting the most important study of his nascent career. He couldn’t have known it yet, but things were about to go very wrong.
Water agencies across San Diego County are doing their part to stabilize the state’s power grid during this week’s heatwave by generating hydropower and altering operations to trim electricity demands – and they are offering long-term solutions to reduce future energy shortages.
The California Independent System Operator issued a statewide Flex Alert from Sunday through Wednesday, calling for reduced electricity use in the afternoon and evening to limit power outages. Blackouts could affect hundreds of thousands of San Diego County residents, if extreme heat persists.
