Former Energy Secretary James Schlesinger and renewable energy expert Robert L. Hirsh opine in the Washington Post today,
Why are we ignoring things we know? We know that the sun doesn’t always shine and that the wind doesn’t always blow. That means that solar cells and wind energy systems don’t always provide electric power. Nevertheless, solar and wind energy seem to have captured the public’s support as potentially being the primary or total answer to our electric power needs…
Realistically, however, solar and wind will probably only provide a modest percentage of future U.S. power. Some serious realism in energy planning is needed, preferably from analysts who are not backing one horse or another.
