[An example of how weather uncertainty can throw off alternative energy power sources; New Zealand relies heavily on hydropower, which has been undermined by two years of drought. Like Juneau, its backup power is fossil fuel-based, a backup plan that peak fossil fuels will make less reasonable. Left with few other options, New Zealand is going the route of encouraging efficiency and conservation.

"New Zealanders are to be urged to wash dishes by hand and turn off lights as the country teeters on the brink of a power crisis caused by drought.

"After two years of dry weather, the level of water in lakes that drive New Zealand's hydroelectric power plants is worryingly low.

"The energy minister, David Parker, denied claims the country was facing rolling power cuts but said households would be asked to cut electricity consumption by up to 15% during peak early evening periods unless there was 'significant' rainfall soon.

"Hydroelectric stations usually produce about 75% of New Zealand's electricity but a lack of rain has reduced that output in recent weeks to 50%. Coal, diesel and gas-fired power plants are trying to make up the shortfall, but more strain is expected to be put on the national grid with the arrival of winter in the southern hemisphere.

"Backed by the government, the electricity industry is to launch a TV campaign aimed at domestic, commercial and industrial users."
