Alternative Energy vs Water?

AMARGOSA VALLEY, Nev. — In a rural corner of Nevada reeling from the recession, a bit of salvation seemed to arrive last year. A German developer, Solar Millennium, announced plans to build two large solar farms here that would harness the sun to generate electricity, creating hundreds of jobs.

But then things got messy. The company revealed that its preferred method of cooling the power plants would consume 1.3 billion gallons of water a year, about 20 percent of this desert valley’s available water.

Now Solar Millennium finds itself in the midst of a new-age version of a Western water war. The public is divided, pitting some people who hope to make money selling water rights to the company against others concerned about the project’s impact on the community and the environment.

“I’m worried about my well and the wells of my neighbors,” George Tucker, a retired chemical engineer, said on a blazing afternoon.

Here is an inconvenient truth about renewable energy: It can sometimes demand a huge amount of water. Many of the proposed solutions to the nation’s energy problems, from certain types of solar farms to biofuel refineries to cleaner coal plants, could consume billions of gallons of water every year.

“When push comes to shove, water could become the real throttle on renewable energy,” said Michael E. Webber, an assistant professor at the University of Texas in Austin who studies the relationship between energy and water.

Conflicts over water could shape the future of many energy technologies. The most water-efficient renewable technologies are not necessarily the most economical, but water shortages could give them a competitive edge.

Water for Auction in California

By Bettina Boxall, LA Times

Need more water? If you’ve got $30 million or so, you can bid for it at an auction this fall.

In what officials believe is a first for the state, a Southern California water agency is planning to auction off enough water to supply about 70,000 homes for a year.

Water sales are not uncommon in California, especially when supplies are tight, as they are in the current drought.

But putting water up for bid in an auction — which is bound to drive up the price — appears to be unprecedented in the state.

“Water in general has always been a very low-priced commodity, and I think the reality is, it’s going to start catching up with other utilities. It’s going to fluctuate with markets,” said Ken Manning, chief executive of Chino Basin Watermaster, a quasi-public entity that manages the basin. “Whether that’s right or wrong, I don’t know. I just know where it’s going.”

Manning anticipates that the water will fetch $800 to $1,000 an acre-foot, or roughly $30 million. Underground storage in the basin will cost another $30 million.

“We think we’re offering a reliable product. It’s in the ground. So it will demand a higher price,” he said.

Mississippi River Delta to “Drown” by 2100?

July 15, 2009 by Editor  
Filed under The Southeast

By Rebecca Carroll, for National Geographic News

The Mississippi River Delta is drowning, according to new research that predicts the surrounding coastline will be inevitably reshaped in coming decades.

“There’s just not enough sediment to sustain the delta plain,” said study author Michael Blum of Louisiana State University in Baton Rouge.

Deltas are coastal landmasses created from a river’s sediment deposits as the water flows out to sea. The Mississippi River’s delta plain, for example, includes the lacy “toe” of southern Louisiana. (See a Louisiana map.) All deltas are degrading to some extent, as their sediment settles and sinks. But a delta can sustain itself or even grow if its parent river regularly deposits enough new material.

Today sediments collected along the Mississippi cover about 23,360 square miles (60,500 square kilometers) ranging in thickness from less than 33 feet (10 meters) upstream near Memphis, Tennessee, to about 328 feet (100 meters) in the delta at the tip of southern Louisiana.

The drainage basin of the roughly 2,350-mile-long (3,782-kilometer-long) river, however, includes about 40,000 dams and levees built over the past century.

These structures control flooding and improve navigation, but they also trap sediment or funnel it completely through to the sea.

Previous studies suggested that dams and reservoirs built since 1950 have trapped as much as 70 percent of the river’s natural amount of sediment. With less material feeding it, the delta plain has been experiencing erosion.

But even without the dams and levees, the amount of sediment flowing downriver would no longer be enough to sustain the delta because of rising seas, the study authors say.

Tough Choices

The researchers base their conclusions on estimated delta levels over the past 12,000 years, which show significant changes more than 7,000 years ago, when meltwater from the last ice age quickly filled the oceans.

The Mississippi Delta plain retreated inland at that point, and it was only after sea level rise had slowed considerably that the delta again grew seaward. Current sea level rise, however, may be three times faster than it was the last time the delta was able to grow.

The team therefore estimates that as much as 5,200 square miles (13,500 square kilometers) of delta land could disappear by 2100—an area only slightly smaller than Connecticut.

For now the study authors don’t have a solution, and they add that plans to save the delta plain—such as redirecting and possibly adding sediment—will almost certainly involve sacrifices.

“They can [divert sediment to areas] downstream from, say, New Orleans, but that means that areas [of the delta plain] farther upstream will be submerged,” Blum said.

“Tough choices have to be made, and they need to be made fast.”

Expert explains a world suffering from water shortage

This is a very interesting video about the water situation in the World and in the US, with some useful recommendations at the end.

One of the Largest Public Health Issues of Our Time

November 7, 2008 by Editor  
Filed under Editorial

As the planet’s once plentiful blue resource gets used up, companies are acting to secure their supply and become more efficient users of water.  A business publication from the UK called Ethical Corporation has published an interesting report on this trend, which we’ve pulled excerpts from here:  

The world’s water supplies are drying up. Half of the planet’s wetlands have disappeared over the past century. In Europe, six in every 10 cities with more than 100,000 people are using their groundwater supplies at a faster rate than they are being replenished, the European Environment Agency reports.

Water experts have coined the phrase “water stressed” to describe the scenario. It’s reckoned that countries require 4,654 litres of water per year per person to meet citizens’ needs. If they fall short, they are said to be stressed.

Today, the term covers about 440 million people, including the inhabitants of European states such as Denmark and Poland. In much of the Middle East and some parts of Africa the situation is even worse.  By 2075, the number of people in regions with chronic water shortages is estimated to be between three and seven billion, according to the Stockholm International Water Institute.

So what’s behind the water scarcity? In short: man. The world’s population has tripled over the past century and is expected to increase by about 50% to more than nine billion by 2050.

Simple population growth is not the whole answer, however. Rapid rates of industrialisation, urbanisation and wealth accumulation mean that people are now using on average six times more water than they were a century ago. Water consumption is expected to continue doubling every two decades, a recent report by Goldman Sachs says.

Virtually every industrial activity requires water. The likes of power-generation, mining, paper and drinks sectors are particularly water intensive. Non-industrial services, meanwhile, such as tourism and entertainment, can depend heavily on water resources as well.

Even the water that industry doesn’t use up is often made unpotable. Back in 2001, before an official crackdown on pollution, Chinese businesses were dumping an estimated 23.4bn tonnes of sewage and industrial waste a year into the Yangtze river. In Europe, only five of the continent’s primary rivers are considered pollution-free.

Farming’s thirst

By far the biggest water-use culprit, however, is agriculture. Farmers are thought to be responsible for 70% of all human water use. That percentage is set to rise, according to the Sri Lanka-based International Water Management Institute. Farmers will need 2,000tn litres of water a year by 2030 to keep pace with the world’s growing food needs, the institute says.

Climate change presents an additional threat to world water supplies in the coming century.  It is predicted that global warming will increase evaporation rates across much of the planet and cause freshwater held in glaciers to melt. Rainfall could also drop off dramatically in some parts of the world.

It’s not only policymakers that need to worry about a world with less water. Business should be concerned too. Today’s panic over the scarcity of credit could be minor in comparison with tomorrow’s threat of water scarcity.

“Lack of water of adequate quality directly reduces production,” says Marc Levinson in a recent report by the investment bank JP Morgan. Agriculture, drinks and food processing are most vulnerable to water shortages, he says. All businesses, however, would be affected by the increased input costs that would result from diminishing water supplies. Companies would also see their capital expenditure rise as they were forced to find expensive new ways of treating and extracting water.

Levinson raises the further spectre of regulatory risk. To date, rules governing water use and discharge have been relatively light for companies. Many countries subsidise water use for agriculture. Introducing water permits and fixed prices are two obvious ways governments could intervene to control water use.

Drought-hit Australia shows what might be round the regulatory corner. Earlier this year, it introduced a cap on ground and surface water usage for the Murray-Darling Basin, the country’s most important agricultural area.

The probability of reputation damage presents a third major risk for the business community. As access to water decreases, people will be looking to point the blame. “Water is a very emotional issue and, although business isn’t the biggest user of water, it risks being the first to be cut off,” says Anne Léonore Boffi, water project office at the Geneva-based World Business Council for Sustainable Development.

Coca-Cola knows this only too well. Five years ago, campaigners in the south Indian state of Kerala began blaming the US soft-drinks company for a sudden shortfall in local water supplies, dubbing it “Killa Cola”. Its bottling plants were accused of polluting local aquifers.

Many risks lurk in multinationals’ supply chains rather than their own direct activities: food and drink companies, for example, depend heavily on irrigated agriculture for raw materials.

JP Morgan estimates that the combined water consumption of Nestlé, Unilever, Anheuser-Busch, Coca-Cola and Danone approaches 575bn litres a year – enough to cover the daily basic water needs of everyone on the planet.

Israel Could Bring Solutions to L.A. Water Shortage

October 17, 2008 by Editor  
Filed under The Southwest

By Lilly Fowler

There was a time when the actions to solve Los Angeles’ water problems read like a dystrophic political novel.

At the beginning of the last century, L.A. Mayor Frederick Eaton and William Mulholland, superintendent of the city’s newly created Los Angeles Department of Water and Power (LADWP), plotted to gain control of water sources in Owens Valley, which left Owens Lake dry and area farmers with little recourse.

The result was the completion of the first Los Angeles Aqueduct, which supplied the city with much of its water from 1913 until a second aqueduct was completed in 1970. (Los Angeles also draws water from Northern California via the California Aqueduct and competes with other Western states for water from the Colorado River.)

The city of Los Angeles recently began atoning for its sins by returning some of the water to the Owens region, which has forced L.A.’s 3.8 million residents to do more with less. With the city’s population expected to reach 4.2 million to 4.9 million by 2020, according to the Southern California Association of Governments, solutions are needed to address the area’s growing water needs.

A recent conference at UCLA’s School of Law, “Transboundary Environmental Management in the Arava and Beyond,” proposed that Los Angeles might gain some ground regarding its often-contentious water policies if the city turned to Israel’s example.

The Sept. 9 forum, sponsored by the Arava Institute for Environmental Studies, a leading teaching and research program in the Middle East, suggested that both Israel and Los Angeles have made many of the same mistakes when trying to develop water in arid, dry lands and could learn a great deal from each other when dealing with issues of water scarcity.

“There are very strong parallels between what’s going on in the Western United States and what’s going on in the Middle East,” said Peter Gleick, the keynote speaker at the conference.

Gleick, a MacArthur Fellow and co-founder of the Pacific Institute, an Oakland-based environmental research organization, said both countries are struggling with the issue of how to best share their water supplies with neighbors. Although Israel, according to Gleick, faces the more complicated problem of sharing water from sources like the Sea of Galilee, natural underground aquifers and the Jordan River with its Jordanian and Palestinian neighbors, the dilemma in both countries is much the same.

Water Usage Up and Reservoirs on Decline in Hawaii

October 14, 2008 by Editor  
Filed under US Water

WAILUKU – Periodic but isolated showers on windward and mauka areas of the islands had little effect on the watersheds, Maui County Water Director Jeff Eng reported Friday.

In his weekly water use report, Eng said water use was up by 620,000 gallons a day in the Central Maui and Upcountry systems, while the water sources for the Upcountry system have continued to falter. 

“I would like to remind our customers of our request for Upcountry customers to reduce water usage by 5 percent and our Central customers to reduce water usage by 10 percent,” he said.  “It’s been a dry week and the upcountry reservoirs have been steadily dropping, going from 100.6 million gallons on October 2 to 81.4 million gallons on October 10. That is less than half of the total storage capacity of 180 million gallons.”

The islands as a whole continue to dry out even with occasional trade-wind showers, with the Big Island suffering the worst of the abnormally dry conditions. The U.S. Drought Monitor expanded the area of North Kohala under extreme drought, increasing the area rated extreme drought from 10 percent to 12.3 percent of the islands.

In California, Drought Prompts Closure of Boat Launch

October 14, 2008 by Editor  
Filed under The Southwest

HEMET – Private boat launches in the Inland Empire’s largest reservoir – Diamond Valley Lake – will be indefinitely suspended starting Tuesday because of low lake levels caused by drought, according to the Metropolitan Water District.

In the meantime, the MWD board of directors Tuesday will discuss options for lengthening the boat ramp so private boats can once again access the lake.

Since 2006, levels at the lake have receded 70 feet, according to Bob Muir, spokesman for the MWD, which runs the reservoir. Of that 70 feet, 24 feet of water has disappeared since January, Muir said.

The water level at the storage facility has dropped to the end of the boat ramp, making it dangerous for private boats to launch. Small fishing boats and rental pontoons can still be used, Muir said.

“This action speaks volumes about the seriousness of the water-supply situation Southern California faces next year, particularly should we not rise to meet the water-saving challenge that’s before us,” said Metropolitan General Manager Jeff Kightlinger.

Ethiopia Says It Needs $266 Million for Emergency Drought Aid

Filed under World's Water

By Jason McLure

Oct. 14 (Bloomberg) — Ethiopia needs $266 million to help feed 6.4 million people suffering from food shortages due to drought, an increase of 1.8 million since June, the government said.

Millions of peasant farmers and pastoralists in the Horn of Africa country are struggling to cope with the affects of the failure of the short rains in February and March, known as the “belg,” Mitiku Kassa, the state minister for agriculture and rural development, said today in the capital, Addis Ababa.

“It is unprecedented, the failure of the belg,” Kassa said at a meeting with international donors. “We need additional resources.”

International relief agencies need 270,245 metric tons of food to meet aid needs from September to December of this year. Donors have pledged less than two-thirds of the aid requests made earlier this year, Kassa said.

About 80 percent of Ethiopians rely on rain-fed farming even though the economy has experienced double-digit growth over the past four years. Beyond the number of people needing emergency aid, another 7.4 million people depend on a donor- funded “safety-net” program that provides food to families for at least six months of the year.

Ethiopia, a nation of 78 million people, now has 50,000 tons of food in its emergency reserves, down from 400,000 normally.

Shortages of emergency food reserves hampered the response effort to the drought earlier this year, the agriculture ministry said in a report today.

Many Changes Await in Colorado’s Future

THE PUEBLO CHIEFTAIN

DENVER – Some January day in the future, you might be sitting in your living room, drinking coffee made from bottled water and looking across the sand dunes in the front yard.

You’ll glance at the headlines and notice that the Colorado economy is finally bouncing back from the triple whammy of a poor ski season last year, failed crops in most parts of the state and the loss from forest fires the previous summer.

Oh yeah, and the heat wave that started Christmas Day will be about to end as high temperatures return to the temperate 60s. Still no snow in the mountains, though.

Then, you’ll wonder, “How did this happen?”

A conference last week in Denver looked at ways to avoid that particular picture, or maybe just alert people that sooner or later they may be coping with such a scene. The painting of the future was not pleasant, as a report by the University of Colorado and the Colorado Water Conservation Board depicted it in a theme of gray to black tones. Less white snow, blue water and green trees than you’d like to see. Maybe more red ink for those who need to cope with the economic fallout.

“If you knew 10 years ago that the stock market was going to go into a bear cycle beginning in October 2007, how would you have prepared?” asked Bill DeOreo, an engineer. “You need to be looking at what’s the best way to integrate drought into a long-range water conservation plan.”
