It's totally useless as long as you don't shut down plants that are running on coal. Otherwise it's just adding up with other sources of CO2.
Google is still closely associated with California to many people (and to a lesser degree New York), but it's determined to change that reputation. The company is launching a $13 billion expansion in 2019 that will give it a total US footprint of 24 states, including "major expansions" in 14 states. The growth includes its first data center in Nevada, a new office in Georgia, and multi-facility expansions in places like Texas and Virginia. This is on top of known projects like its future New York City campus.
This plant is used to power up an expansion of google, which means it's just adding up CO2 to what we already emit. It's creating a fake impression that we are reducing our carbon footprint.
There is a simple solution: shut down the datacenter. No more power needed, no more water needed. The problem is not about CO2, it's about us refusing to let go our previous way of life.
