The Carter administration set a goal of deriving 20 percent of U.S. energy needs from such renewable sources by the turn of the century. Today, the U.S. gets a mere 7 percent of its energy from renewables, the bulk of that from the massive hydroelectric dams constructed in the middle of the 20th century. Solar thermal and photovoltaic technology combined provide less than 0.1 percent.

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "The Carter administration set a goal of deriving 20 percent of U.S. energy needs from such renewable sources by the turn of the century. Today, the U.S. gets a mere 7 percent of its energy from renewables, the bulk of that from the massive hydroelectric dams constructed in the middle of the 20th century. Solar thermal and photovoltaic technology combined provide less than 0.1 percent." in the context of "David Biello, in "Where Did the Carter White House's Solar Panels Go?" in Scientific American (August 6, 2010)" to mean that wisdom is timeless.
