The sun is setting in the Coachella Valley as I type this, but somewhere on the other side of the world, I feel certain, it is shining and possibly there’s a solar panel there converting the sunlight to electricity and reducing the carbon emissions that fossil fuel power would have generated.
The spread of solar around the world is part of the story contained in figures from the European Photovoltaic Industry Association. As of 2012, the world had a bit more than 101 gigawatts of PV running around, producing the same amount of power as 16 coal or nuclear plants of 1 gigawatt each, while reducing carbon emissions by 53 million tons.
Of those 101 GW, just shy of 30 GW were installed last year, about the same as 2011, the EPIA said. What’s more important, the geographic spread of PV installations is expanding.
Thirteen gigawatts of solar are now outside Europe, compared to 8 GW in 2011, the EPIA reported. Germany is still the world leader, with 7.6 GW, while China has 3-5-4.5 GW and the U.S. has 3.2 GW. Another report from Greentech Media projects growing solar markets, about 3 GW, in Africa and Middle East in the next two years.
Meanwhile, wind energy is also hitting new highs in terms of how much power it supplies in different states, according to Pete Danko writing on the Earth Techling website.
From midnight Monday to midnight Tuesday, three wind farms in eastern Washington pumped out 16,593 megawatt-hours of power, or about 23.5 percent of the power Puget Sound Energy needed for its 1.1 million customers. Danko writes:
While wind power rises and falls with the varying wind speed – obviously – Puget Sound said its three wind farms are providing at least some power two-thirds of the time and on average are supplying about 10 percent of the power its customers use.
Texas is also breaking records on wind production. The state leads the nation in wind installations over al,l and at 7:08 p.m. on Feb. 9, those turbines were spinning away, producing 9,481 megawatts of power, 10 percent over the previous record of 8,667 MW.
The Feb. 9 high mark represents 28 percent of the load on the state’s power system.
Meanwhile in Colorado, Xcel Energy reported that wind power accounted for 16 percent of the 35.9 million megawatt hours of electricity it sold in 2012.
The missing link to drive those numbers even higher is, of course, storage. California may be taking a step toward new green energy ceilings to break with a recent decision from the state’s Public Utilities Commission ordering Southern California Edison to add 50 MW of grid storage over the next eight years.
Writing about the order on Greentech Media, Jeff St. John notes it’s a relatively small amount of storage, but provides a signal that the state is serious about integrating wind and solar power onto the grid by the 2020 deadline for reaching the state’s renewable energy goal of 33 percent.
In the context of total energy production, in the U.S. or worldwide, all these new benchmarks may be relatively small, but they reflect a vision and momentum that will continue to push renewable energy ceilings higher and higher.
