I am trying to look up the cost and benefits to implement the green new deal and I can not find any such cost benefit analysis.
I understand that the benefits may be a bit intangible so I guess I am just going to ask for the cost.
As the people stated in the comments the plan itself is pretty vague. So in the absence of those details we must refer to similar proposals from the past.
Here is a well written summary. It references a left wing think tank that estimates the cost (the summary of your question) at around 200 billion per year. His estimate was to get to 40% renewable energy in 20 years. The new proposed green new deal aims to get to 100% in ten years. Let’s assume the study is right (bad assumption) and that this is a linear function (it isn’t) for ballpark's sake. If it takes 200 billion to get to 40% renewable in 20 years, it would be a trillion a year to get to 100% in 10 years.
Two things to note.
These numbers again, are anything but rock solid but I hope it gives you some framing.
