Not everyone agrees that Tesla is an environmentally-friendly automaker, even though it builds only electric vehicles. And now a small group has done something to bring greater attention to its cause. Far-left activists are claiming responsibility for a fire that broke out in the middle of the night near the still under construction Tesla Gigafactory in Berlin, Germany.

The fire occurred early Wednesday morning and damaged some power cables above the ground leading to the site. Authorities are considering this an attack because a flammable liquid was used to set those cables alight. Tesla was lucky more significant damage didn't happen.

Not long after the fire was set, the activists posted a letter on a popular reader platform admitting they had cut the power supply to the factory site by purposely setting fire to six high-voltage cables.

"Tesla is neither green, ecological, nor social," said a group spokesperson. "On the night of May 25th to 26th, 2021, we cut the power supply to the construction site of the Tesla Giga factory in Grunheide near Berlin by setting fire to six high-voltage cables laid above ground. Our fire stands against the lie of the green automobile."

Tesla's energy supplier who owns the cables confirmed the act of sabotage did not directly affect the factory itself. Giga Berlin will be Tesla's first European factory, and it may not be the last.

It will be building the Tesla Model Y at launch and it's expected to add the Model 3 at a later date. A total of 500,000 Model Ys could be produced annually there. If all goes according to plan, the new factory will go online by the end of this year. Tesla also intends to build a battery cell plant nearby. It's certainly possible this activist group or others like it could make a second and more damaging attempt to disrupt Tesla's German operations.

The report didn't specifically mention this but we're sure additional security is being brought in to safeguard the construction site.
