The clean energy sector weathered more storms this year, and not everybody made it through.

Here we mark the names of the fallen, those companies that went bankrupt, ceased operations or otherwise exited the sector. The ranks include top-five rooftop solar installers, prominent lithium-ion alternative vendors, a quixotic aboveground compressed air storage play, a solar cell manufacturer with global geopolitical implications, and a couple nuclear plants for good measure.

On the whole, the list was short, a far cry from the bloodbath of 2012. Herman the Solar Death Skull has grown more reclusive, and dedicates much of his time to perfecting his savasana up in the leafy Coast Ranges. Still, once in a while the mountain lions catch a scent, and he follows their silent steps down to the valley to hunt.

The legacy of these companies echoes in the eternity of Greentech Media's comment section.
