Over the past ten years, wind energy capacity within the U.S. has grown by more than 960 percent. Last year wind alone accounted for 42 percent of the total new U.S. electrical capacity installed, and wind energy capacity grew an astounding 22 percent in 2012 alone.
One reason for this remarkable growth can be found in the declining price of renewable energy installations. Since 2008, the price of commercial wind turbines has declined by nearly 30 percent. In 2011, the State Department’s Bureau of International Information Programs (IIP) published that wind power production costs had reached parity with the cost of producing electricity with coal (traditionally considered the cheapest source of electicity). And while the cost of wind power continues to decline, the cost of energy produced by coal continues to rise.
The U.S. currently has about 6,500 megawatts of installed solar capacity, enough to power more than 1 million homes. This represents a growth in generating capacity of more than 1,200 percent in just five years.
Once again, this exponential growth can be traced to declining prices. Over the past five years, the price of installed systems has been more than cut in half. And in recent years, declines in the cost of solar panels have resulted in even more dramatic price reductions. From the third quarter of 2011 to the third quarter of 2012, the average cost of an installed PV system dropped by 33 percent, and the average price of a solar panel declined by 58 percent.
Should the growth of wind and solar slow and only double each year, within five years they would account for more than 50 percent of all the energy consumed within the U.S. While this dramatic growth rate seems highly unlikely, given production limitations and inherant barriers to market (hard to convert a natural gas power plant to solar just because it is a cheaper process)—should give one pause. The transition may take place much faster than most industry watchers imagine.
In a marketplace dominated by headline stories of visible failures such as Solendra, few Americans realize that (according to the Government Accountability Office) the electricity generated by fossil fuels receives $5 in federal subsidies for every $1 received by the renewable energy industry.)
