CALIFORNIA IS LOW ON GAS???!

Water isn't the only resource running short in California. The drought-stricken state is also low on natural gas.

With a move that usually comes in the height of summer when temperatures are soaring and air conditioners blasting, Californians were urged to voluntarily cut their electricity use after frigid weather across the U.S. and Canada caused a shortage of natural gas at Southern California power plants.

The so-called Flex Alert, in which residents are asked to turn off unneeded lights, avoid using large appliances or equipment, and turn off electrically powered heaters, was allowed to expire at 10 p.m. Thursday, nine hours after it began.

The shortage was only in Southern California, but the north was asked to do its part too.

"Statewide electricity and gas conservation will help free up both electricity and gas supplies for Southern Californians," the California Independent System Operator, which runs the state's power grid, said in a statement.

There was no immediate call for an extension of the alert, but it wasn't clear whether more could be coming.

Stephanie McCorkle, a spokeswoman for the grid operator, said Southern California has become increasingly dependent on natural gas-fired plants since the decision last year to shutter the troubled San Onofre nuclear power plant, which is located between Los Angeles and San Diego.

Water struggle on the Nile

Addis Ababa, Ethiopia -- Ethiopia rejected a proposal that would guarantee Egypt the rights to most of the Nile River’s water, as disagreements cast doubt over future talks about Africa’s biggest hydropower project.

The 6,000-megawatt Grand Ethiopian Renaissance Dam on Ethiopia’s Blue Nile River, set to be completed in 2017, has raised concern in Cairo that it will reduce the flow of the Nile, which provides almost all of Egypt’s water. The Blue Nile is the main tributary of the Nile.

The $4.2 billion dam 30 kilometers (19 miles) from Sudan’s border will benefit agricultural and powerinterests in the region and not cause water losses downstream, Ethiopia says. Sudan supports thehydropower project designed to produce electricity for much of East Africa that began in April 2011.

Egyptian officials at a Jan. 4-Jan. 5 meeting that also included representatives from Sudan, introduced a “principles of confidence-building” document asking Ethiopia to “respect” Sudan and Egypt’s water security, said Fekahmed Negash, the head of the Ethiopian Water and Energy Ministry’s Boundary and Transboundary Rivers Affairs Directorate. Discussing the issue would contravene an agreement signed by six Nile countries, he said in a phone interview on Jan. 6.

“We will not negotiate on this issue with any country,” Fekahmed said from Ethiopia’s capital, Addis Ababa. “That is why we say take it to the right platform” that includes other members of the Nile Basin, he said.

1959 Accord

Egypt argues its 1959 agreement with Sudan that gave Egypt the rights to 55.5 billion cubic meters out of a total of 84 billion cubic meters is the governing document on the Nile’s water. The rest of the river’s flow was for Sudan or lost to evaporation. Ethiopia and other upstream nations reject the accord they were not signatories to and say Egypt’s domination of the Nile has unfairly deprived them of a vital resource.

Ethiopia also rejected an Egyptian suggestion to immediately form a panel of neutral experts to adjudicate any disputes arising from planned studies of the dam’s hydrological and environmental impact, Ethiopian Water and Energy Minister Alemayehu Tegenu said. Experts can be hired if they’re needed, he said in an interview Jan. 5 in Khartoum.

Egypt won’t send a delegation to Addis Ababa unless Ethiopia’s government signals its intent to resolve the areas of dispute, Egyptian daily Al-Masry Al-Youm quoted Egyptian Irrigation Minister Mohamed Abdel-Moteleb as saying on Jan. 6.

Talks Impasse

“We have exhausted all opportunities to negotiate with Ethiopia because of the intransigence of Addis Ababa,” Abdel- Moteleb said.
