My colleague Richard Morrison has a hilarious blog post today featuring two Wall Street Journal columns, one from 1978 forecasting solar power meeting 20% of U.S. energy needs by 2000 (actual amount: about 1/10th of 1%) and a recent WSJ column announcing that renewable fuels may meet 25% of our energy needs by 2025.  The most renewable thing about renewables is, apparently, the techno-fantasies they inspire.
