[LA Times] What do Icelanders know about heat? Quite a lot, it turns out. For 70 years, the chilly island nation has been tapping the Earth’s warmth — using geothermal energy to heat buildings and swimming pools, melt snow and generate more than a quarter of the country’s electricity. And now they’ve come to California to share the knowledge. The effort will be formally launched today in downtown Los Angeles, where Iceland President Olafur Ragnar Grimsson and a handful of city and state officials will open the new headquarters of Iceland America Energy, the company that will lead Iceland’s geothermal push in North America.
