TVA needs to listen to former chair S. David Friedman about solar power

Will you bet on the blinkered money-only policies of the current TVA Chair, or the accurate clean solar future predictions of former TVA Chair S. David Friedman?

Seven years ago S. David Friedman wrote:

“As a substitute for oil, coal, and nuclear energy, the sun can replace the three poisons with inexhaustible fuel.”

The former TVA Chairman wrote that in 2007 his boook Winning Our Energy Independence: An Energy Insider Shows How, which also says (page 4):

There are breakthroughs in new technology that promise to make the cost of solar power as low as that of coal, nuclear, and oil. Almost simultaneously in South Africa and the Silicon Valley in the United States, companies are building huge new solar factories to manufacture a paper-thin solar coating that can generate electricity that could actually lower our electric bills. These breakthroughs promise solar power at 75 percent less than today’s price. Continue reading →

As predicted U.S. solar capacity grew more than 400% in 4 years

This month’s eia report confirms that solar did exactly what former FERC Chair Jon Wellinghoff predicted: “That’s what is happening in solar. It could double every two years.” Wellinghoff’s further prediction remains on the money: “…at its present growth rate, solar will overtake wind in about ten years. It is going to be the dominant player.” Because of exponential growth like compound interest caused by ever-falling solar PV costs, solar will win like the Internet did.

U.S. Energy Information Administration (eia) wrote 22 April 2014, Solar-electric Generating Capacity Increases Drastically in the Last Four Years,

U.S. solar capacity increased significantly in the last 4 years. In 2010, the total solar capacity was 2,326 MW which accounted for a comparatively small fraction (0.22%) of the total U.S. electric generating. capacity. By February 2014, this capacity increased 418% to 12,057 MW, a 9,731 MW gain, and now accounts for almost 1.13% of total U.S. capacity. Reported planned solar capacity additions indicate continued growth

12,057 / 2,326 = 5.18 times, which is more than 2 * 2 = 4, ergo Wellinghoff was right. Continue reading →
