"Environmentally friendly"? No, they use crazy amounts of power.
"High-paying, long-term" jobs? Working in a data center may be in the tech field, but it doesn't offer what people think of as "tech money" and your opportunity for advancement is slim. Data centers also don't need to employ large numbers of people. They just suck up space and resources.
Edit:
The data center industry’s demand for electricity is growing so much that it could threaten Washington’s efforts to transition to a carbon-free power grid....
The original bill required each data center to create at least 35 permanent positions at 150% of the surrounding area’s average personal income.
A second bill, approved just a month after lawmakers passed the first tax break, gave recipients the choice between creating 35 jobs or just three positions per 20,000 square feet of server farm space, whichever was less.
Oh look, I was right. Could have told you all that before the state wasted money on this.
