- Doubling fuel efficiency of 2 billion cars from 30 to 60 mpg Wow - that might slow the growth. Demographics need to be recognized. - Decreasing the number of car miles traveled by half How? - Using best efficiency practices in all residential and commercial buildings Yup - I do not see any numbers. - Producing current coal-based electricity with twice today’s efficiency Coal - sacre bleu - no place for a high carbon fuel in the 80% dream - Replacing 1400 coal electric plants with natural gas-powered facilities As a natural gas investor I love that one. The issue of where the gas would come from - is - well - an inconvenient question - this one is ludicrous! - Capturing and storing emissions from 800 coal electric plants Ludicrous - how - and how much energy would the capture take? - Producing hydrogen from coal at six times today's rate and storing the captured CO2 Ludicrous - Capturing carbon from 180 coal-to-synfuels plants and storing the CO2 Possible - how much energy does the capture take and how much energy does the generation of O2 take? - Adding double the current global nuclear capacity to replace coal-based electricity Now are getting somewhere. - Increasing wind electricity capacity by 50 times relative to today, for a total of 2 million large windmills Noise around the edge. - Installing 700 times the current capacity of solar electricity Fine - what percentage is that? - Using 40,000 square kilometers of solar panels (or 4 million windmills) to produce hydrogen for fuel cell cars H2 goes boom very easily. - Increasing ethanol production 50 times by creating biomass plantations with area equal to 1/6th of world cropland Absolutely ludicrous. The environmentalists have already caught up with the ethanol fraud - Eliminating tropical deforestation and creating new plantations on non-forested land to quintuple current plantation area Say what - see item above. - Adopting conservation tillage in all agricultural soils worldwide What does this do for CO2?
