Based on the title, I was expecting this to be about the idea of power transmission via microwave (as seen in e.g. SimCity), but actually it's about microwave communications links used by electrical companies.

history lesson about power transmission lines in the us

its a summary, an explanation of whats in the article that the heading fails to address, as the sibling comment attests... you could call it clickbait busting and wouldnt be too far off

Thank you, I found your summary helpful because the article doesn’t start with any explanation about what it will cover.
