$this->bbcode_second_pass_quote('PStarr', 'W')hen 100 million Indians/Bangladeshis deplete their shallow water wells and run out of irrigation diesel will that affect your next meal out? How about that Chilean phospate mine? Will it operate when the Chileans are hungry and angry.
I model relatively similar declines for most developed nations but more modest declines in less developed countries because I think they have less fat to cut, and some are generally in a much stronger growth position, while others have low requirements and probably won't be allowed to fall into disarray by the international community. Disagree? Spreadsheets available on request.
$this->bbcode_second_pass_quote('PStarr', ' ')What fraction of national our petroleum use does not support your dinner? Can you quantify that?
Sure, let's discuss individual sector cuts. I'll use the most pessimistic model, Ace/Simmons with no 2G biofuels. On a 2020 timeline, global usage declines to 58% of current value and I've modeled the U.S. to absorb a much steeper decline to 48% of current value. Pretty gut-wrenching stuff. That's basically what we produce now (with emergency drilling more or less counteracting depletion) plus a few mbd of XTL plus a few mbd of tarsands. Very close to a no-import situation for the Canada-U.S. bloc, which is as bad as it gets.
Some of the key cuts by sector, and analysis:
(41%) Personal transportation, cut to 30%. 10% relocalization, 30% telecommuting/carpooling/public transit, 40% increased vehicle efficiency.
(13%) Trucks, cut to 47%. 30% improved efficiency (electric trucks for local routes, aerodynamics), 20% replacement with rail, 15% sector destruction (longest-distance routes eliminated).
(10%) Plastics, Fertilizer, etc., cut to 64%. 20% Improved Efficiency (smaller bottles etc.), 15% Recycling, 15% substitution with other feedstocks (depending on item)
(7%) Air Travel, cut to 50%. Enough said.
(5%) Process heat, cut to 20%. It seems like it would be very easy to substitute a point heat source in most processes, but I'm open to correction on this point.
(5%) Heat and hot water, 55%. Reduced usage (20%), alt-technology substitution, 30% (gas, electric, solar thermal, heat well, etc.)

')Electrified farms? You're kidding me. Have you ever been on a farm? Who and when will purchase the electric dryers, augers, tractors, harvesters, bailers, loaders, Rails from where to who? What grid? What powerplants?
(2%) Agriculture, 85%. Equipment efficiency gains, 10%. Reduction in tillage 7% (marginal beef feed land mostly, meat is an easy thing to cut back on and it is going to be very expensive.)
(1.2%) Rail, 200%. The rail industry is booming, already expects to double capacity between 2030, so this seems well within scale if oil prices spiral upwards.
