Here were some of the highlights:
--End all power generation from fossil fuels (about 39%). While it would include a serious ramp up in production of solar and wind, it really can't be done as quickly as possible without one other source: nuclear. Yes, it has its own problems, but they look piddling compared to runaway AGW.
--Retrofit all residential & commercial buildings to use electricity as its power source (about 10%). This means not only things like adding solar panels on the roofs, but also removing things like furnaces fueled by heating oil or natural gas. Again, not easy or inexpensive, but at least feasible in a way that's not real lifestyle-changing.
--Electrify non-marine freight transportation (about 8%). Now things get tricky. About the only way this gets done is to concentrate it on electrified rail lines. But this is not easy financially nor logistically. It also means the end of air freight, which would slow down deliveries considerably in that realm.
--Electrify personal transportation (cars, light trucks, and buses, about 17%). One can only hope that the electric car's future isn't that far away, but the feasibility of getting it widespread in the short timespan that's likely necessary looks very poor.
--End the raising of at least red meat and dairy (about 6%, not sure if this included poultry as well). I added this last one in here as an intentional eyebrow raise. Of the five points listed above, this one is hypothetically the easiest to do. But how many people do you see willingly giving this up? Yeah...
Adding up all those percentages got to an 80% reduction in GHGs, a percentage that I believed was cited as being necessary within a decade or two. The other 20% I think was for things more critical to humans that weren't easily substituted, like non-animal based agriculture. The bottom line is that there is so much that needs to be done, or so much that needs to be sacrificed, and it looks quite unlikely of happening.
I'm not sure I can even imagine a Civic archetype that could pull it all off...
