Plying the Water-Energy Nexus

by Miles Ten Brinke

Miles, Peak Water columnist and avowed Hydrophilic energy-head, has found his way to Britain where he’s lost his California perma-tan and is studying an Energy Policy MSc at the University of Exeter on a Fulbright.

Growing up the in the American Southwest is an education in the triumph of human ingenuity and the creeping hazards of its peril. From Palm Springs to Las Vegas we’ve made the desert bloom- a green oasis of shopping malls, suburban lawns and sprawling golf courses. It is a socio technical system built on a foundation of innovative engineering large and small, from the proliferation of air conditioning to the California aqueduct and the Hoover Dam. Even amidst the bust of the Great Recession and its aftermath, the boom of these places is so resonant* it’s easy to forget just how fragile and contingent the whole enterprise truly is. Climate change looms ahead, and the water’s running out. Even amidst all the changes ahead, the world’s driest places will see their rains dwindle. They’ll only get drier. In the Southwest, the Colorado no longer feeds into the sea. In California in particular, the vast majority of the water (and other resources) is consumed in the South yet it’s sourced in the North. This system defined by overconsumption is no longer tenable; the region’s decision makers need search out viable alternatives. Much as the global energy system needs a transition to a more equitable, secure, efficient and decarbonized alternative so too must our water socio-technical systems change. I’ve personally come to be defined by that reality.

Though I’ve lived now around the world, for the vast majority of my life my family and I lived in the Southwest, split mostly between Las Vegas and the Inland Empire of Southern California. We lived in Vegas for most my primary and secondary education, my folks moving us to California when I started high school. It’s where I started my post-secondary education, at Mount San Jacinto College. These spaces, Nevada and California, have shaped me and the course my life’s taken. Resource management is a priority for any public policy, but it’s vital in the desert. For all the clever development, water shortages are an ever-present and deepening concern in these places. The efficient consumption of water and other resources is both a necessity and a central source of contention. People get used to their cars, to their lawns, their shopping malls, housing developments and rapid economic growth. We forged an oasis and struggle to maintain it. This dynamic, this dilemma is one I’ve grappled with from the onset of my career in energy over five years ago. I got my start in Socal as a student participant in a K-12 energy efficiency education program which provided the training, tools and support to conduct an energy audit of one’s campus and even implement changes. The lesson, amidst the greatest recession we’d known since the 30s, was the value maximal throughput at minimal expense. Our resources are finite, precious. How we choose to consume defines not only our economic activity, but shapes our culture and socio-natural landscapes all around us.

This has resonated with my experiences ever since. Through further jobs and voluntary work I came to an understanding of everyday energy use efficiency beyond simply the kWh; demand management in energy policy is as much about the careful management of our water for the future and the planet as innovations in energy conservation and technologic efficiency. Energy and water are inextricably linked, whether the connection between the energy inputs to the mass agricultural sector of California and its behemoth thirst or suburban sprawl with its house-as-castle populism and everything in-between. These parallels and intersections are deep, and many.

After completing a B.S. in Society & Environment at UC Berkeley focusing on Global Environmental Politics I’m now on a Fulbright-University of Exeter Postgraduate Student Award pursuing an Energy Policy MSc at the Exeter Cornwall campus. I’m in my second term now, developing another energy specialism-in water policy as it relates to energy. From this entry on, Peak Water readers you can join me on this new path as I explore the energy-water nexus. I’m as a much a student on this journey as you, let’s pursue it with an unquenchable curiosity and a humble openness to learn. Maybe in the process we can even start to shape a new vision of the global water transition, of its interconnections with energy and its realization.

Best of luck to us along the way, it should prove an interesting ride.

NYT: Laos Presses Ahead With Mekong Dam Project

Retrieved From: International Rivers

BANGKOK — Ignoring criticism that a huge hydroelectric dam could irreparably damage the ecology of the Mekong River, the government of Laos said on Tuesday that it was pushing ahead with the multibillion-dollar project, the first dam to be built on the lower portion of the iconic river.

“I would say I’m 100 percent sure it’s going ahead,” Daovong Phonekeo, deputy director general of the Laotian Department of Electricity, said by telephone on Tuesday.

Laotian government officials and executives of a Thai construction company that is to build the dam are to officially inaugurate the project at a ceremony on Wednesday in Xayaburi, the remote province in northwestern Laos where the dam is to be situated.

The electricity from the project will be sold to Thailand and will provide billions of dollars of revenue to Laos, one of the poorest countries in Asia. But the project has been criticized by scientists who are concerned that the dam may disturb spawning patterns and lead to the extinction of many species of fish that have for centuries been the main source of protein for millions of people along the river’s banks.

The Great Lakes legacy: Old contaminants declining; newer ones on the rise

Retrieved From: Environmental Health News

Legacy contaminants are decreasing more quickly than previously reported in three of the Great Lakes, but have stayed virtually the same in two other lakes, according to new research. “These are very positive results. The lakes are improving and slowly cleaning themselves up,” said Thomas Holsen, co-director of Clarkson University’s Center for the Environment. Even with the decreases, it will be 20 to 30 years until the decades-old contaminants in Great Lakes fish decline to the point that fish consumption advisories can be eliminated. Banned in the 1970s, PCBs, DDT and other banned compounds dropped about 50 percent in fish in Lakes Michigan, Ontario and Huron from 1999 through 2009, although there were no significant changes in Lakes Superior and Erie fish, according to the new study. In all of the lakes, the older contaminants are being replaced by newer ones, mostly flame retardants, that are building up in fish and wildlife.

Newmont Mining Suspends $4.8 Billion Peru Gold Mine Operation After Violent Protests Over Water Supply

“LIMA, Peru — A $4.8 billion gold and copper mining project, Peru’s biggest such investment, was declared suspended Tuesday after increasingly violent protests by highlands peasants who fear for their water supply.

At least 20 people, including eight with gunshot wounds, were injured Tuesday in clashes between opponents of the Conga project and police who used firearms, Cajamarca state regional health director Reynaldo Nunez told Canal N television. He said one person was in critical condition and the injured included police.

“After discussions with the government, it was agreed that to help restore public order, the project would be suspended,” Newmont Mining Corp. spokesman Omar Jabara told The Associated Press via email. Denver-based Newmont is the majority owner of Conga, which was to begin production in 2015 and is an outgrowth of Yanacocha, Latin America’s biggest gold mine.”

More Radioactive Water Leaks at Japanese Plant

“TOKYO — At least 45 tons of highly radioactive water have leaked from a purification facility at the Fukushima Daiichi nuclear power station, and some of it may have reached the Pacific Ocean, the plant’s operator said Sunday. Nearly nine months after Fukushima Daiichi was ravaged by an earthquake and tsunami, the plant continues to pose a major environmental threat. Before the latest leak, the Fukushima accident had been responsible for the largest single release of radioactivity into the ocean, threatening wildlife and fisheries in the region, experts have said. The new radioactive water leak called into question the progress that the plant’s operator, Tokyo Electric Power Company, appeared to have made in bringing its reactors under control. The company, known as Tepco, has said that it hopes to bring the plant to a stable state known as a cool shutdown by the end of the year.

The trouble on Sunday came in two stages, a Tepco statement said.  In the morning, utility workers found that radioactive water was pooling in a catchment next to a purification device; the system was switched off, and the leak appeared to stop. But the company said it later discovered that leaked water was escaping, possibly through cracks in the catchment’s concrete wall, and was reaching an external gutter.  In all, as much as 220 tons of water may now have leaked from the facility, according to a report in the newspaper Asahi Shimbun that cited Tepco officials.

The company said that the water had about one million times as much radioactive strontium as the maximum safe level set by the government, but appeared to have already been cleaned of radioactive cesium before leaking out. Both elements are readily absorbed by living tissue and can greatly increase the risk of developing cancer.”

Africa’s great ‘water grab’

The banks of the Niger river, in southern Mali, have been flooded by a steady stream of foreigners. Coveted by foreign investors eager to snap up large tracts of fertile farmland, the river basin has been at the centre of a race to get hold of African land at rock-bottom prices. Meanwhile, last week, hundreds of smallholder farmers and civil society activists flocked to the same river basin for the first international conference to tackle the global rush for land.

West Africa‘s largest river, the Niger is thought to sustain over 100 million people as it snakes 4,180km through Guinea, Mali and Niger before emptying into Nigeria’s colossal Niger Delta. In Mali, the Office du Niger is home to the vast majority of the country’s largescale land deals, seen by campaigners as emblematic of the “land grabs” taking place in developing countries. Recent estimates suggest that foreign investment in Mali’s limited arable land jumped by 60% between 2009 and 2010. But the potential knock-on effects of these land deals on local communities’ access to water has rarely made it centre-stage.

Ongoing research from the London-based International Institute for Environment and Development seeks to redress this blindspot, honing in on how such land deals might affect water access for fishing, farming and pastoralist communities. In a policy paper out on Thursday, the IIED’s Jamie Skinner and Lorenzo Cotula warn that an alarming number of African governments seem to be signing away water rights for decades, with major implications for local communities.

Unusual drought triggers alarm across Balkans

“The waters of the mighty Danube are so low that dozens of cargo ships are simply stuck, stranded in ghostly fog or wedged into sand banks on what is normally one of eastern Europe’s busiest transport routes.A lack of rain has triggered the worst drought in decades for this time of year, dropping river levels to record lows and sounding an alarm in parts of central and eastern Europe. Power supplies are running low in Serbia, drinking water shortages have hit Bosnia, and crop production is in jeopardy in Romania, Bulgaria and Hungary. The Czech Republic is at its driest since records began in 1775.

Meteorologists say they are not sure why the region has had far less rain than average since August — but they don’t see any more coming quickly. That is bad news for shipping companies that are already reporting big losses.”

Australia’s Breadbasket Faces Water Squeeze

“CANBERRA—A plan to reduce water use in Australia’s key food-producing region is pitting farmers against environmentalists and throwing the long-term future of the country’s breadbasket into question.

The release of a draft plan to cut the supply of irrigation water in the Murray-Darling Basin, an area about the size of Texas and California combined, has angered both sides. Conservationists say it isn’t enough to restore local river systems and farmers say it could cost thousands of jobs and drive up food prices.

The basin, degraded by drought, state governments’ overallocation of water rights and by rising levels of salinity in the soil, an effect of irrigation, generates about 15 billion Australian dollars (US$14.7 billion) in agricultural produce a year, mostly grains, livestock and fiber. It accounts for 40% of national farm output by value and well over half of irrigated farm production, using nearly all the water held in the basin area.

The new plan, published over the weekend, proposes to recover 2,750 gigaliters of water a year—more than five times the volume found in the Sydney Harbour area—from irrigators in the Murray-Darling Basin. One gigaliter, a billion liters, is enough to fill about 444 Olympic swimming pools.”

Scientists Propose Thinning Sierra Forests to Enhance Water Runoff

Retrieved From: www.1888Mammoth.com

“Runoff from the Sierra Nevada, a critical source of California’s water supply, could be enhanced by thinning forests to historical conditions, according to a report from a team of scientists with the University of California, Merced, UC Berkeley and the Environmental Defense Fund.

The team proposes to test the hypothesis that forest-management strategies that use thinning to reduce fire risk and maintain the historical mix can also increase water yield and extend the snowpack in the Sierra Nevada.

The scientists suggest that by selectively reducing the number of trees — which use large amounts of the water received through precipitation — the amount of water that is released from the forest as runoff could increase. This enhanced runoff could make things easier for farmers and water managers statewide.

As part of the Sierra Nevada Watershed Ecosystem Enhancement Project (SWEEP), the scientists plan to reduce forest density in test areas and examine the impacts on water runoff, forest health and other ecosystem services, and provide a template for broader forest management in the Sierra Nevada.”
