Prices of natural gas in the US have risen 93% since August 2007 and as global demand continues prices are expected to fuel inflation in the US. Producer prices were up 1.1% in March according to Labor Department and natural gas prices contributed to this increase. Natural gas heats half of uS homes, supplies 20% of USA electricity and is used to make products from fertilizer to plastic bags. And demand from the US power sector is growing at 10% a year as natural gas is clean burning to produce electricity at power plants and preferrable to caol burning plants from environmental standpoint. With environmetal regulation and costs natural ga ma be preferred by plants for power generation. A revolution has ocurred in the way natural gas is cooled into liquid LNG and transported in LNG tankers so that places like Nigeria and Quatar can now ship to Japan and Europe. And LNG contracts are now written in less rigid terms so that supplies are not fixed over 10 year periods like before and can be diverted by suppliers to other markets where prices have risen so that when a nuclear power plant shuts down in Japan LNG supply can be diverted to Japan from other countries because of vastly higher prices in Japan. This also happens elsewhere last year a drought in Spain cut hydroelectric power and Spain turned to Algeria and Egypt which had already diverted supplies to Japan which paid prices twice as high as Spain, so Spain secured supplies from Trinidad a US supplier, which reduced supplies to the US by 31% over 2006. So this shifting global supply chain means shortages and prices in one place can reverberate all the way to the USA. Because of these and other reasons US prices are expected to go much higher by estimates from Barclays and Deutsche Bank....
