The electricity shortage underscores the slow progress in rebuilding the war-torn country. It also feeds other problems. Old factories sit idle and new ones are not built. Produce withers without refrigeration. Dark, cold homes foster resentment against the government.
In Kabul, power dwindles after the region's hydroelectric dams dry up by midsummer. This past fall, residents averaged three hours of municipal electricity a day, typically from 7 p.m. to 10 p.m., according to USAID, the American government aid agency. Some neighborhoods got none.
"That's a scary sounding figure because it's pretty tiny," said Robin Phillips, the USAID director in Afghanistan. "So we're talking about the relatively poorer people in Kabul who have no access to electricity at this time of year."
Electricity was meager under the Taliban, too, when Kabul residents had perhaps two hours of it a day in fall and winter. The supply has since increased, but not as fast as Kabul's population - from fewer than 1 million people in the late 1990s to more than 4 million today.
Meanwhile, souring US relations with Uzbekistan have delayed plans to import electricity from that country. Power is not expected to arrive in a significant way until late 2008 or mid-2009.
"Life takes power," said Jan Agha, a 60-year-old handyman from west Kabul who recalled how the city had plentiful power during the 1980s Soviet occupation. "If you have electricity life is good, but if there's no electricity you go around like a blind man."
Some in Kabul do have electricity: the rich, powerful, and well connected.
Municipal workers - under direction from the Ministry of Water and Energy - funnel what power there is to politicians, warlords, and foreign embassies. Special lines run from substations to their homes, circumventing the power grid. International businesses pay local switch operators bribes of $200 to $1,000 a month for near-constant power, an electrical worker said anonymously for fear of losing his job.
