The reason we call deniers deniers, is that they solve problems by simply pretending they don’t exist. Anthropogenic climate change doesn’t exist. No problem.
Another problem that simply does not show up on climate denial radar screens is the problem of water supplies. We constantly read glowing press accounts about plans for massive development of new exotic fossil fuel sources in the US, very often in western states, with no balanced consideration of some very serious constraints on those processes. One big one is water.
We’ve seen numerous instances in the past decade of power plants being shut or derated during the very times we need them most, big heat waves in the summertime, because they can’t continue to operate at full power without boiling away the rivers that cool them, or cooking all the fish therein. Likewise, we also continually hear that China and other developing countries are going to continue building thousands of new thermal power plants, in the face of already critically limited water supplies.
It ain’t going to happen. The evidence is all around. I discussed the issue at the American Geophysical Union with water expert Peter Glick – part one above, part two tomorrow.
SHANGHAI — The world’s biggest coal consumer now has a new incentive to take a cleaner energy path, as China’s coal-fired power plants are drying up the country’s already scarce water resources.
A report published today by Bloomberg New Energy Finance notes that the top five Chinese power generators — China Huaneng Group, China Datang Corp., China Huadian Corp., China Guodian Corp. and China Power Investment Corp. — have hundreds of gigawatts of coal-fired power plants in the country’s dry north and that retrofitting them with water-efficient solutions could cost billions of dollars.
“Today, 85 percent of China’s power generation capacity is located in water-scarce regions and 15 percent of this still relies on water-intensive, once-through cooling technologies,” said Maxime Serrano Bardisa, one of the report’s authors as well as Bloomberg New Energy Finance’s water analyst.
At the same time, the nation is seeing less and less water. According to separate research by the China Environmental Forum, an initiative of the U.S.-based Woodrow Wilson International Center for Scholars’ global sustainability and resilience program, China’s total water reserves dropped 13 percent from 2000 to 2009, with the water shortage being particularly severe in the north.
The coal industry has played a big role in the shortage, the report says. Northern China has 20 percent of the country’s freshwater supply, but its coal mining and coal-fired power generators are thirsty for water. Bloomberg New Energy Finance estimates that in 2010 alone, the two sectors combined withdrew 98 billion cubic meters of fresh water across the region — or nearly 15 percent of China’s total freshwater withdrawals in the year.
If the five Chinese power giants continue their current development of coal-fired plants, the report predicts, the sector’s water withdrawals will exceed 25 percent of China’s 2030 target to cap its national water withdrawals at 700 billion cubic meters per year. Some Chinese regions have already extracted underground water faster than it is being replenished, and any increase in water withdrawals could further push China away from an environmentally sustainable future.
There are solutions to ease the water stress, but each comes with major trade-offs.
