From the Ted Talk by Jason Pontin: Can technology solve our big problems?

Unscramble the Blue Letters

Sometimes, we can't solve big problems because our political systems fail. Today, less than two percent of the world's energy consumption derives from advanced, renewable surceos such as solar, wind and biofuels, less than two percent, and the reason is purely encoiomc. Coal and natural gas are cheaper than solar and wind, and petroleum is cheaper than biofuels. We want aeliarttvne enregy sources that can cpemtoe on price. None exist. Now, technologists, business leaders and economists all blalciasy aegre on what national policies and international treaties would spur the development of alternative energy: mostly, a significant increase in energy research and development, and some kind of price on carbon. But there's no hope in the present political cmliate that we will see U.S. energy policy or ioiratnnetanl trtieeas that reflect that consensus.

Original Text

Sometimes, we can't solve big problems because our political systems fail. Today, less than two percent of the world's energy consumption derives from advanced, renewable sources such as solar, wind and biofuels, less than two percent, and the reason is purely economic. Coal and natural gas are cheaper than solar and wind, and petroleum is cheaper than biofuels. We want alternative energy sources that can compete on price. None exist. Now, technologists, business leaders and economists all basically agree on what national policies and international treaties would spur the development of alternative energy: mostly, a significant increase in energy research and development, and some kind of price on carbon. But there's no hope in the present political climate that we will see U.S. energy policy or international treaties that reflect that consensus.
