Estonia eager to teach world about oil shale

In this March 2013 photo, oil shale rock is processed in northeastern Estonia by removing limestone that is mined along with it. After this “enrichment” process the shale can be used to produce electricity in power plants or undergo further refining to make a variety of liquid fuels. Estonia, which burns shale to meet over 90 percent of its annual electricity needs, is attempting to export its unique technological expertise to shale-rich countries such as Jordan and the United States. Home to the creators of Skype and the first country to use online voting, Estonia relishes its image as a technological pioneer. But the tiny East European country's most far-reaching economic achievement could come from how it has learned to squeeze oil from a rock. (AP Photo/Gary Peach)
