Although the overall growth in capacity for solar and wind are growing faster than the capacity for nuclear or coal, renewables still amount to only a small percentage of the overall power generated.

And solar is still the smallest source of electricity, according to the monthly report from the Energy Information Administration.

In the first four months of the year, the U.S. consumed 1,314,683 million kilowatt hours.

Solar accounted for 205 million kilowatt hours. That's around 0.02 percent when you round up.

Wind accounted for 17,566 million kilowatt hours.  Or 1.3 percent.

Coal came to 658,750 million kilowatt hours, thereby accounting for about 50 percent still.

Nuclear and natural gas are still near the 20 percent mark.

So what does that mean? Huge opportunities for solar installers.

On the liquid fuel side, the U.S. produced 5.3 million barrels of oil a day and 1.8 million barrels a day of natural gas/plant liquid fuel in the first six months of the year. In all, the U.S. consumed around 18.6 million barrels a day. That's down from 19.9 million in 2008 and over 20 million in 2007.
