EVs cause oil spills!

Reading the article, I'm not seeing any connection to EVs. Can you point out to me what I'm apparently overlooking?

Looks like the oil was from an oil-cooled electrical transformer.

Now wait for the people that were not concerned by the Exxon Valdez or the Deepwater Horizon accidents to make a big deal how unacceptable an environmental risk EVs are. But, of course, any other use of electricity is perfectly acceptable.....

I too did not see the correlation to EVs but yet an interesting article.
