Get an eye-opening look at some of the world's most important case studies in smart energy decisions. In Spain and Morocco, large-scale solar farms and individual photovoltaic panels atop tents in the Sahara are beginning to bring the sun's vast potential down to Earth. In Brazil, abundant natural resources (sun, rain and sugar cane) are transformed into efficient, sustainable biofuel. In Samsø, Denmark, and West Texas, citizens have taken sustainability, and economic realities, into their own hands by becoming stakeholders in wind turbines. In China, a full-throttle approach to multiple sustainable energy technologies is giving rise to a "new empire of clean tech." Great nations and small communities alike are finding sustainable solutions that provide for people and protect the Earth. But what about America — are we making the right decisions for our country's energy future?
