Mercury is poisonous, yet it’s a critical part of most compact fluorescent light bulbs (CFLs), the kind that environmentalists and some governments are pushing as a new way to cut energy consumption. Mercury is probably best known for its effects on the nervous system. It can also damage the kidneys and liver, and in sufficient quantities can cause death.

There were an estimated 150 million CFLs sold in the United States in 2006 and, and Wal-Mart alone hopes to sell 100 million in 2007. Some scientists and environmentalists are worried that most are ending up in garbage dumps. U.S. regulators, manufacturers and environmentalists note that, because CFLs require less electricity than traditional incandescent bulbs, they reduce overall mercury in the atmosphere by cutting emissions from coal-fired power plants.

When it comes to energy, Brazil is on its way to becoming a “global brand.” Although the United States recently outpaced Brazil in ethanol production, Brazil is by far the leader in sugar-based ethanol. Its exports are growing, and it could become a major energy supplier to the world. But what Brazil is particularly known for is its grand conversion-moving almost 40 percent of its automotive fuel from gasoline to ethanol.
