Solar Panels Are Finally Generating More Energy Than They Use

[The Straight Story]

You want an inconvenient truth? Here’s one: Despite the exponential growth of solar energy over the past 13 years, the global production of photovoltaic panels has consumed more electricity than the panels themselves generate, according to a new Stanford University study.

As recently as 2008, the photovoltaic (PV) industry used 75% more energy than it generated (paywall), found the paper published in the journal Environmental Science and Geology.

Such figures, of course, could prove highly problematic for an industry whose existence is predicated on reducing greenhouse gas emissions by supplying carbon-free electricity.

Now for the good news. There’s more than a 50% chance that the industry reached a tipping point last year and is now producing more electricity than it consumes. By 2020, it should have paid back all the power it consumed since 2000, according to the analysis conducted by Stanford researchers Michael Dale and Sally Benson. “Developing new technologies with lower energy requirements will allow us to grow the industry at a faster rate,” Benson said in statement.

1. it's not "despite"... it's "because of"

It's only because of the incredible growth of the last couple years... where most of the production capacity is brand new.

The fact that much of that capacity isn't being used... and much of what is used isn't installed yet... doesn't help.

Take all your atomic poison power away.

3. Building an infrastructure takes time and investment

But like the interstate highway system, will pay dividends for generations to come.
