[ A Cold War Over Resources in Central Asia ]

Earlier this year, a U.S. intelligence report predicted that as water shortages become more acute, “water in shared basins will increasingly be used as leverage” over the next 10 years and beyond.  This prediction is already being borne out in places such as Uzbekistan and Tajikistan (map), where long-standing distrust between the two nations has been heightened by new disputes over natural gas and water supplies.

Tajikistan gets nearly 95 percent of its natural gas from Uzbekistan. It also controls upstream access to Uzbekistan’s water supply, a lot of which goes to irrigate the latter’s cotton fields. Citing new contractual commitments of natural gas supplies to China, Uzbekistan interrupted gas deliveries to Tajikistan for half of April 2012, which nearly paralyzed the Tajik economy.

While disruption of Uzbek gas supplies to Tajikistan has been a recurring story, Uzbekistan has a new gripe with its neighbor: Tajikistan’s Roghun hydroelectric dam project on the Vaksh River. One of the nation’s most ambitious projects since 1976, the Roghun will replace Tajikistan’s Nurek hydroelectric station as the world’s tallest dam and meet more than enough of its electricity demand, with a capacity to generate 3.6 billion kilowatt-hours of electricity per year. Uzbekistan has been against Roghun, fearing the dam will disrupt its supply of irrigation water for its cotton fields. Given that Roghun poses no real benefit to Uzbekistan, the Uzbek authorities are concerned that Tajikistan may use it as leverage in future disputes.

Tajik President Emomali Rahmon has been pushing for more investment to complete the Roghun dam in recent years, and Uzbekistan’s pressure on its neighbor has steadily risen in response. Tashkent increased tariffs on its neighbor for railway transit, suspended railway movement linking the two countries in November 2011, and reportedly began dismantling the railway connection in March of this year, basically cutting Tajikistan off from the rest of the world. Over 130 wagons with essential goods destined for Tajikistan and northern Afghanistan continue to stand idle along the Amuzang-Galaba stretch. Reportedly, Uzbekistan refused Tajikistan’s request to allow fuel transports from Turkmenistan via its territory on the grounds that Turkmen and Uzbek pipeline systems functioned separately. Worsening the relations further, borders of both countries remain strewn with land mines since Tajikistan’s civil war in the 1990s, and visa requirements complicate cross-border travel.

Disputes over water in Central Asia are nothing new. But they appear to be getting worse as demand for water grows in the region and upstream countries, such as Tajikistan and Kyrgyzstan, fail to come to agreements with downstream Uzbekistan, Kazakhstan and Turkmenistan. Water use is deeply politicized, and upstream countries are inclined to exploit it as leverage to obtain certain economic concessions. Many Tajiks consider Roghun important for their country’s energy supply security, particularly after Uzbekistan’s repeated interruptions of gas deliveries. Whereas Tajikistan validates the Roghun project by pointing to its growing demand for electricity, Uzbekistan’s concerns about this venture go beyond a potential shortage of irrigation water.

The dam’s location in a seismically active area is not a minor factor. Situated at an elevation of 335 meters, Roghun could face damage from an earthquake or structural fault that would cause flooding of nearby towns and even settlements in Afghanistan, Uzbekistan and Turkmenistan. The World Bank, which essentially has been serving as a mediator of the Tajik-Uzbek dispute over Roghun, recommended in 2011 that the country should postpone its construction because of substantial amounts of sediment brought on by the Vakhsh River. Some Tajik observers have pointed out that a layer of salt under the future dam makes it susceptible to landslides if the salt melts.  Security at the facility is another concern, given that Tajikistan faces ongoing problems with extremist elements and porous borders with neighboring Afghanistan. According to Muhiddin Kabiri, chairman of Tajikistan’s Islamic Renaissance Party, his country is not prepared to counter terrorist attacks.

The World Bank will release an independent environmental assessment of the Roghun dam by the end of 2012. But Uzbekistan will stay opposed to the dam regardless of the assessment’s outcome. Given the longtime influence of Uzbekistan on Tajikistan’s internal affairs, including its help in ushering the current government in the capital Dushanbe to power after the Tajik civil war in 1997, the Uzbek leadership might bring an end to Rahmon’s rule through more economic and political pressure, which could provoke domestic discontent over worsening living standards. With presidential elections looming in 2013, the best that the Rahmon’s government could do to prevent that scenario would be to delay the construction of Roghun.

[ Energy Efficiency: Gaining Traction or Spinning Its Wheels? ]

Congress, businesses, and consumers show an appetite for the proverbial low-hanging fruit.

Remember the Brouhaha Over the Light Bulb Efficiency Standard?

On December 19, 2007, the Energy Independence and Security Act [pdf] became law with bipartisan Congressional support and a stroke of President George W. Bush’s pen. The bill attempts to reduce energy consumption and enhance national security in the United States through a number of provisions including increasing fuel-economy standards, improving building codes, and increasing biofuel production.

(Related Quiz: What You Don’t Know About Energy-Efficient Lighting)

The law also mandates greater efficiency in household light bulbs, a measure already adopted by most other developed economies, including countries in the European Union [pdf], Australia and China (whose phase-out of inefficient lights is set to begin in October 2012).

But all that was back before bipartisanship became a dirty word. When 2011 rolled around and the clock on implementing the first phase of the light bulb standard began to tick down, outrage over the prospect of Americans losing the “freedom” to purchase their light bulbs of choice began sounding throughout the land (see here and here), on talk shows (~6:02), in presidential stump speeches, and in Congress.

(Related: Light Bulb Savings Calculator)

Last July Rep. Joe Barton’s (R-TX) “Better Use of Light Bulbs” (BULB) bill to block the new standards won a simple majority in a 233-193 vote in the House, but failed to get the necessary two-thirds support to go forward. Days later, the House passed by a voice vote an amendment introduced by Rep. Michael Burgess’s (R-TX) to an appropriations bill that would defund implementation of the new light bulb standards. A similar amendment effectively delaying implementation of the standards until October 2012 was passed by Congress in December. Barring Congressional action in the next four months that would repeal parts of the Bush-era Energy Independence and Security Act, more efficient “100-watt” light bulbs will be the rule instead of exception in the United States come October.* (See here and here.) And as per the 2007 law, greater efficiency from other light bulb classes will follow (see chart below).

Phase-Out Schedule of Inefficient General Service Incandescent Light Bulbs

Current Wattage Rated Lumen Ranges Maximum Rate Wattage Minimum Rate Lifetime Effective Date
100 1490-2600 72 1,000 hours 1/1/2012
75 1050-1489 53 1,000 hours 1/1/2013
60 750-1049 43 1,000 hours 1/1/2014
40 310-749 29 1,000 hours 1/1/2014

(Sources: Energy Independence and Security Act and Sylvania)

Tea Party Out of Step

The battle over light bulb standards may end up being just a skirmish in an all-out war against energy efficiency standards. Tea Party activists and like-minded conservatives see a sinister agenda in efforts to make America more energy efficient. (See here and here.) According to a New York Times article, moves toward energy efficiency have been seen as a plot to advance the United Nations’ Agenda 21 resolution, deemed by activists tied to the Tea Party to be a UN-led conspiracy to subject Americans to a “one world order.”

The results of a survey released last Monday by the Deloitte Center for Energy Solutions and Harrison Group suggest that the Tea Party may be whistling the wrong tune on this one. The two-part survey included “one-on-one interviews with senior executives across all industries, as well as over 600 online interviews with business decision makers” and “2,200 demographically balanced online interviews of consumers.”

The findings? Both business leaders and consumers were bullish on energy efficiency. Why? Because it saves money. Perhaps most fascinating was the silver lining the responding consumers saw in the recession: “61% believe that ‘going through the recession has ultimately been good because it makes us more efficient and reminds us what is important.’”

Most of the companies surveyed said [pdf] they planned on maintaining the energy savings they achieved during the downturn and many said they planned on finding additional savings. Why is energy efficiency becoming more of a business favorite? Economics, not the environment. The survey found that “85% of businesses view reducing electricity costs as essential to staying competitive from a financial perspective.”

Is Congress Ready for More?

All this may explain why Congress is tiptoeing toward possible passage of two new bipartisan energy-efficient bills: the Energy Savings and Industrial Competitiveness Act (S. 1000) [pdf] sponsored by Sens. Jeanne Shaheen (D-NH) and Rob Portman (R-OH) and the Implementation of National Consensus Appliance Agreement Act of 2011 (S. 398) introduced by Sens. Jeff Bingaman (D-NM) and Lisa Murkowski (R-AK), which would basically be an update of the Federal Appliance Standards program that President Ronald Reagan signed into law in 1987. The two bills would set energy codes for buildings and standards for manufacturing as well as provide for worker training. The American Council for an Energy-Efficient Economy estimates that together the two bills would ultimately:

  • add up to 100,000 new jobs by 2020,
  • save consumers about $5 billion per year, and
  • cut U.S. greenhouse gas emissions about 130 million metric tons of carbon dioxide per year by 2030, or about 2 percent relative to today.

Sounds like a good deal. Even the U.S. Chamber of Congress thinks so ($ub r’qd).

State Prognosis on Energy Efficiency

With thriftiness looking like it will stick for most consumers and businesses, and Congress threatening to get into the bipartisan energy-efficiency act, one has to wonder how the states are doing on their own.

Easy question to answer thanks to the American Council for an Energy-Efficient Economy’s new state energy-efficiency scorecard. Like most scorecards, there are those on the top and those at the bottom. And there aren’t any great surprises there.

The top ten: Massachusetts, California, New York, Oregon, Washington, Vermont, Rhode Island, Minnesota, Connecticut, and Maryland.

At the bottom: South Dakota, Alabama, Missouri, West Virginia, South Carolina, Oklahoma, Kansas, Mississippi, Wyoming, and North Dakota.

Energy Efficiency Scorecard
,” American Council for an Energy-Efficient Economy/Michael Sciortino, Rachel Young, and Steven Nadel, May 2012. Used courtesy of ACEEE.)

So what’s keeping the bottom 10 from getting into the act? According to survey results also published in the ACEEE report, the most common barriers are:

  1. A belief that energy efficiency is prohibitively expensive;
  2. A misalignment of utility business model, where utilities see energy efficiency as in opposition to their profits instead of a pathway to avoid costly investments in new power plants; and
  3. Ideological aversion to mandates.

Of course some of the states at the bottom of the list are big producers of fossil fuels and might just see energy efficiency as something that would put a damper on their profits by lowering the demand for and therefore the price of those fossil fuels. Interestingly, according to the Deloitte survey, most corporations and consumers, who have to pay the high prices, don’t see it that way. Unless Congress gets its act together and passes a nationwide bill, we could end up at a stalemate — a nation divided over energy efficiency. Instead of red and blue states, we could have fossil fuel-brown and energy-efficient green states. Which type of state would you choose?

_____________

End Note

* Lights currently referred to as “100 watts” will need to use a maximum of 72 watts under the new standards. Lumens, which refer to the amount of light produced, will appear on light-bulb packages along with the new wattage. Putting it all together, today’s “100 watt” bulbs that produce about 1600 lumens will need to use 72 watts or less once the new standards go into effect.

[ Memorial Day and outdoor escapes – why we love LWCF ]

Image: 

Memorial Day weekend is here!  Summer vacation starts now, and for many Americans (and certainly people reading this) that means getting outdoors and into nature. So it’s a good thing that Americans have so many places to get outside – more than 600 million acres of public land, and more 110 million acres protected as Wilderness. Many of those protected acres are because of a program called the Land and Water Conservation Fund. 

We’re highlighting a few of the places that the Land and Water Conservation Fund has protected.  Places like the Appalachian Trail, where the Land and Water Conservation Fund helped connect the full length of the trail.

In Mt. Rainier National Park, Land and Water Conservation Fund dollars are expanding the park.  This expansion will improve access for people, and improve habitat for spotted owls and Chinook salmon.

The Land and Water Conservation Fund is responsible for some of the great places to get outside across the country.  Don’t take our word for it – check out what it’s done for your state

All this weekend on Twitter we’ll be talking about why we love the Land and Water Conservation Fund.  Join the discussion with the #WhyWeLoveLWCF hashtag, and get outside and enjoy some of the places that are protected because of the Land and Water Conservation Fund!

And if you’ve already been out to a place protected by the Land and Water Conservation Fund, take a minute and sign our petition.  We want to make sure that Congress protects the Land and Water Conservation Fund, so that it can keep protecting wild places!

[ Diving into Español, rivers and outreach: The 411 on our first Public Lands Fellow ]

Image: 

Fabiola Lao is the first Public Lands Fellow at The Wilderness Society.  Since June 2011 she has been based in the Los Angeles office working on the San Gabriel Mountains Forever campaign.

As her year comes to an end, and before she heads to the Sierra Club to continue working on San Gabriel Mountains Forever, Fabiola dished about her fellowship.

Q: You were born in Perú, but raised in Los Angeles. And you have both Chinese and Peruvian heritage. Did that help your work on the San Gabriel Mountains Forever campaign?

A: Los Angeles is a very multicultural city, and the campaign is reaching out to all potential users of the mountains – and that includes many Asian and Latino communities. I use my Spanish language skills very often, particularly when reaching out to the Latino community. I don’t speak Chinese, but so many of the visitors we see in the mountains are Asian. It’s pretty common to hear Korean or Chinese on the trails.

Q: Did The Wilderness Society jump on your translator skills?

A: Almost immediately!  I have translated web pages and press releases into Spanish, and suggested we use ‘Sociedad para la Naturaleza Silvestre’ as the translation for The Wilderness Society’s name.  And I have also been an interpreter at our San Gabriel Mountains leadership academy classes when some students spoke mostly Spanish.

Q: Speaking of Spanish skills, you did one of the first Spanish-only radio interviews for us?

A: Yes, it was for a public radio talk show in San Francisco back in the fall, and I talked about the congressional bill known as the “Great Outdoors Giveaway” bill.

With Congresswoman Grace Napolitano in Washington at Great Outdoors America week

Q:  To date, what are you most proud of during your fellowship?

A:  Probably two things.  The first one was going to Washington D.C. and being able to tell several Congress members how important it is to create a San Gabriel Mountains National Recreation Area.  The second is organizing a community art show near La Crescenta, the town where I grew up, which is next to the San Gabriel Mountains.

Q: We also hear you really got your feet wet on a TWS river outing?

A: It’s true. I’m still learning how to paddle in white water, but I had a blast even if I flipped into the river during that Utah rafting trip…twice!

Prior to The Wilderness Society, Fabiola worked at environmental health and environmental justice non-profit organizations including Program Coordinator at the Breast Cancer Fund and Policy Analyst at the Latino Issues Forum. She has dual Bachelor in Arts degrees in Interdisciplinary Studies (Public Health concentration) and Spanish Language and Literature from UC Berkeley. She also has a Master in Public Administration from the University of Southern California.

[ BLM can balance conservation, oil/gas development in NPR-A ]

ANCHORAGE, ALASKA (May 23, 2012) – As the federal Bureau of Land Management works to create the first land-use plan for the 23-million-acre National Petroleum Reserve-Alaska, the agency has a historic opportunity to protect some of the world’s most significant wildlife resources that sustain many communities in the western Arctic, according to The Wilderness Society.

“When Congress transferred these western Arctic lands from the Navy to the BLM, they recognized the need to balance protection of special ecological values while at the same time providing opportunity for oil and gas development,” said Nicole Whittington-Evans, Alaska regional director for The Wilderness Society. “Many administrations from both sides of the political aisle have since recognized this need, and the Obama Administration should take this historic opportunity to do all it can to safeguard important wildlife and subsistence resources while providing opportunity for responsible energy development.”

In its recently released Draft Integrated Activity Plan/Environmental Impact Statement, the BLM is considering a range of options that include making some percentage of special areas with high ecological value unavailable for oil and gas leasing and opening the entire reserve to oil and gas development.

The Wilderness Society supports the draft plan’s “Alternative B” option because it protects ecologically important areas with exceptional wildlife and subsistence resources, such as Teshekpuk Lake, the Utukok Uplands and Kasegaluk Lagoon, among others, while allowing responsible oil and gas development in much of the reserve.  The plan also allows for the possibility of a future pipeline to carry offshore oil across the NPR-A, known to many as the Western Arctic Reserve.

“Alternative B is the only option that provides reliable protection of Teshekpuk Lake Caribou Herd habitat,” said Whittington-Evans, basing her position on The Wilderness Society’s extensive modeling of development impacts in the reserve.  The results of this modeling effort will be provided to BLM before the close of the public comment period on June 1. 

The BLM will be holding a meeting at 7 p.m. Thursday in Anchorage’s Campbell Creek Science Center to allow the public to comment on the draft management plan. An open house will begin at 6 p.m.

[ Amsterdam: Hydrogen-Powered Efficiency ]

Laurens van Mulukom, a mechanical engineering student at Hogeschool van Amsterdam, talked about why hydrogen is “one of the most innovative fuels to work with,” at Shell Eco-marathon Europe 2012 in Rotterdam. With this year’s competition that ended Saturday taking place on its home country’s soil, <a href=”http://www.h2a.nu/h2a-news/”>Team H2A</a> was proud to achieve a new Dutch efficiency record for a hydrogen vehicle. The team’s fuel cell system with supercapacitors propelled the vehicle 261 kilometers (162.1 miles) per kilowatt-hour. That is the equivalent of more than 2,300 kilometers per liter (5,460 miles per gallon.)

[ 1Thing Sacramento Tip of the Day: Live Sewer Smart ]

Did you know that the City of Roseville Environmental Utilities makes it easy to get rid your household fats, oils and grease by picking it up for free right at your doorstep?

1Thing Sacramento and the City of Roseville Environmental Utilities have partnered to remind you to never put fats, oils or grease down your sink. Common fats, oils and grease found in kitchens include cooking oils, salad dressings and sandwich spreads, meat juices and fat. When improperly disposed, these substances can have negative effects on a home’s plumbing creating blockages, which in turn will cause the sewer to back up through sinks, drains and toilets. The end result can be a major headache for the homeowner.

Whether you’re a business that generates fats, oils and grease or a resident of Roseville, you’re encouraged to do your part to help prevent sewer blockages. Doing so will benefit your home, your pocketbook and your community. In many cases, damage in residences caused by sewer back-ups is not covered by homeowners or renters insurance.  It also minimizes repair work by the city which helps to keep your sewer utility rates low.

[ Saving America’s Endangered Rivers ]

Saving America's Endangered Rivers

2. Green River

Patrick DiGiulian of EarthShare member organization American Rivers talks about his organization's recent Most Endangered Rivers list along with his personal reasons for wanting to protect the nation's majestic rivers.

 

We all need clean water. No ifs, ands or buts about it. Fresh water is crucial to every living thing on our planet. Most of our drinking water comes from rivers. And rivers and streams also give us places to fish, boat and swim – not to mention homes for wildlife.

On May 15th American Rivers was proud to announce the 2012 America’s Most Endangered Rivers® report. The report highlights ten rivers whose fate will be decided in the coming year, and encourages decision-makers to do the right thing for the rivers and the communities they support.

We chose the Potomac as America’s #1 Most Endangered River for 2012 because of the threat from urban and agricultural pollution. While the Potomac River is cleaner than it used to be, pollution is still a serious problem – and it could get much worse if Congress rolls back critical clean water safeguards.

As a DC resident, the Potomac is especially important to me.  I get my drinking water from it, on the weekends I enjoy running along the Billy Goat trail at Great Falls National Park, and when I have the opportunity I kayak and sail by the DC monuments.  It is amazing how much of my life revolves around one single source.

As we commemorate the 40th anniversary of the Clean Water Act this year, the
Potomac – known as “the nation’s river” as it flows by the capital — is emblematic of what’s at stake for rivers nationwide.

Our president, Bob Irvin, said, “This year’s Most Endangered Rivers list underscores how important clean water is to our drinking water, health, and economy. If Congress slashes clean water protections, more Americans will get sick and communities and businesses will suffer. We simply cannot afford to go back to a time when the Potomac and rivers nationwide were too polluted to use.”

The America’s Most Endangered Rivers® report is one of the best-known and longest-lived annual reports in the environmental movement. Each year since 1986, grassroots river conservationists have teamed up with American Rivers to use the report to save their local rivers, consistently scoring policy successes that benefit these rivers and the communities through which they flow.

American Rivers reviews nominations for the report from river groups and concerned citizens across the country. We look at the significance of the river to human and natural communities and the magnitude of the threat to the river and associated communities. The report is not a list of the nation’s “worst” or most polluted rivers, but rather it highlights rivers confronted by critical decisions that will determine their future. The report presents alternatives to proposals that would damage rivers, identifies those who make the crucial decisions, and points out opportunities for the public to take action on behalf of each listed river.

You won’t be taking action to only protect the places I love and depend on, but you will be protecting the safety and well-being of millions of Americans. 


Take Action to Help Protect These Rivers!

[ Stirling Engine: External Combustion Efficiency ]

One of the most unusual looking cars at this year’s Shell Eco-marathon Europe was testing out one of the oldest concepts for harnessing energy for motion: the Stirling heat engine.

Team Schluckspecht from the University of Applied Sciences, of Offenburg, Germany, designed a vehicle that relied on external heating and cooling to drive pistons. The Stirling engine concept, named after Scottish inventor Robert Stirling who introduced his model in 1816, is sometimes called an external combustion engine because heat is applied from outside the engine.

Unfortunately, the team’s vehicle did not pass the qualifying tests for the competition that ended Saturday in Rotterdam. The car was too heavy and too high, due to the system coils on its roof. But the vehicle did complete some test runs to try out a concept that the students think has promise for future energy systems.

Michael Dold, who is earning his master’s degree in energy conversion at the school, explains one of the Stirling engine’s great advantages is that it can be used with any fuel source. (Team Schluckspecht powered its vehicle on ethanol.)

U.S. government researchers who studied the Stirling engine note that its development was hampered in part because materials that could withstand the high temperatures were not available in the early years of experimentation. Also, the engines were slow to heat up, and couldn’t compete with the spark-ignition engine. Still, automakers in Detroit tested Stirling engines during the oil crises of the 1970s, and a few years ago, Segway inventor Dean Kamen also experimented with the concept. Because of its extreme efficiency, quiet, and fuel versatility, many innovators–including the Offenburg students–think the Stirling engine may have a future in providing energy.
