Many states and cities have long been turning trash into treasure by burning garbage to create heat and electricity, or by harvesting the methane gas that is released as junk decomposes. But in a new twist on this theme, several cities and municipalities are transforming capped landfills—the ultimate waste of space—into solar-power plants.
“When you get done with a landfill, that property’s primary function can no longer be used anymore. It’s a great pyramid of waste,” said Mark Roberts, vice president of HDR, an engineering company that constructs solar-voltaic landfills. “So the question is, What do you do with these facilities when you’ve filled it up. What you can do is cap the landfill in such a way that it meets the EPA requirements but gives you an opportunity to still get benefits from its use.”

On Tuesday, June 25, in a speech before enthusiastic students at Georgetown University, President Obama delivered a message outlining his vision for what the United States ought to do, and what he personally is going to do, about the moral issue of energy production. Now at first glance, you would think that energy production is a technical issue that should be left to engineers and economists. But it was clear from the President’s speech that he thinks it is also a moral issue, as moral as which side you should fight on in a war. His speech, in fact, was peppered with militant terminology. He spoke of having the “courage to act,” he talked of the “fight against climate change,” and expressed his desire for America to “win the race for clean energy.” Toward the end, he called for citizens “who will stand up, and speak up, and compel us to do what this moment demands.” To that end, he announced that he was going to ask the Environmental Protection Agency (EPA) to issue regulations that, according to Obama critic Charles Krauthammer, will “make it impossible to open any new coal plant and will systematically shut down existing plants.”
