Right now on the Senate floor, senators are debating dueling amendments from Sen. Jeff Bingaman, D-N.M., and Sen. Pete Domenici, R-N.M., on a possible "portfolio standard," which the Apollo Alliance describes as "setting the minimum amount of renewable energy that must be developed by retail electricity vendors each year."
Bingaman's amendment would set a national standard of 15% of our electricity to come from renewable sources -- like wind, solar and geothermal power -- by 2020. 20-25% would be ideal, but 15% is a significant step forward.
Domenici's version sets the standard at 20%, but would count electricity from coal and nuclear. That won't do anything to advance wind, solar and geothermal power and move us towards a clean energy future.
