The Green New Deal, as it says in that article, is not a particular proposed piece of legislation but a collection of proposals. Nonetheless, each of these does contain particular proposals. And you didn't pick a proposal, you picked a goal. A sample actual proposal is "invest x dollars over y years upgrading the electrical grid as a necessary precursor to more widespread adoption of variable but renewable power sources". "Invest x dollars over y years to subsidize the transition to electrified transportation", i.e., tax incentives and grants to build charging stations and get people to buy electric cars -- another proposal. These have actually been worked out in excruciating detail in one Green New Deal-esque legislative proposal: the Build Back Better plan. They had to work it out in detail because they had to put a pricetag to it so they could submit it to the Congressional Budget Office. This legislation has a vast amount of detail, but maddeningly its opponents deride it both for being too detailed ("Who could read this doorstop!? We don't know what we're voting on! Government red tape!") and for being a blank check.
