Continuing with our theme that one ought to invest in such a way as to help alleviate the problems facing our world, today we will highlight one emerging opportunity. Chileonaire blog indicates that solar plants built in Chile's Atacama desert "will produce more direct current electricity than almost any other place in the world." What does that mean? It means solar power will be profitable in Chile at a much lower threshold, viz., sooner and for relatively less upfront investment.
Indeed, SolarPlaza indicates that a joint venture between SolarPack and Codelco, Chile's state-owned copper miner, will build the world's first solar plant "without subsidies or specific tax benefits for solar energy." As far as we can tell however, a direct investment in SolarPack is not available to the typical retail investor. Let us hope that with time this changes, and in the meantime there is always Brazilian ethanol and hydroelectricity.
