Technologies for reducing carbon emissions

An article at NextBigFuture lists "Ten Technologies that should have a big impact on Green house gas Emissions". This provides much material for a discussion with Physics students - though the teacher would likely have some research to do! Most teachers would not have heard of many of these. Some are very relevant to us in Guyana. The 10 technologies are:

1. factory mass produced high rises and skyscrapers
2. black carbon free cookers
3. diesel particulate filters for cars and trucks
4. electrification of vehicles
5. retrofitting existing buildings for efficiency
6. reducing carbon dioxide emissions from concrete
7. scaling up of regular nuclear power and hydro power
8. nuclear fission technology advances
9. slash-and-char agriculture
10. biochar
