62% of the world's energy usage is from coal (26%) and oil (36%).
50% of oil is used for cars and trucks. There are one billion cars and trucks in the world and we add 55-65 million each year. So getting older cars and trucks to be much more efficient can have up to twenty times larger and faster impact than rules for making more efficient new cars and trucks.
Retrofitting the older cars and trucks and motorcycles with aerodynamic shells and attachments (commercial CIY aeromodding) can reduce fuel usage by 30-100% at highway speeds.
Retrofit cars and trucks with engine modifications or overhauls to reduce fuel usage.
A Honda 125 cc Innova was increased from 114 mpg to 214 mpg with an aerodynamic shell
There are several do it yourself aerodynamic modifications of Honda Civics to get 90-114 mpg.
Here is a list of vehicle efficiency improvements from Ecomodder
Cars and trucks use about 50% of the oil. The rest if for industrial heat, plastics, some home heating, some rail, some ships, asphalt for roads, etc...
Convert hundreds to thousands of the largest commercial ships to nuclear power could be done faster than converting tens of millions of cars or trucks. There are already hundreds of nuclear submarines and air craft carriers
There are advantages for military and civilization resilience for making nuclear commercial shipping.
The economics of nuclear power for commercial ships makes sense now which is why Cosco ( a large chinese commercial shipping company) is investigating the idea of nuclear shipping.
Economic study showed that a nuclear ship would be $40 million per year cheaper to operate when bunker oil is at $500/ton.
Those studies had indicated improved economics when bunker fuel is over $300/ton. Bunker oil is currently about $375/ton. Also, changing to nuclear powered container ships would reduce air pollution by the equivalent of about 20,000 cars converted to electric per container ship that is converted.
Electrify local transportation - China has 150 million electric bikes. Converting 500 million regular bicycles users to electric bikes. Supply the electric power from nuclear power instead of coal or natural gas.
Factory mass produce nuclear reactors like China HTR-PM pebble bed and Hyperion power generation uranium nitride or uranium hydride reactors (there are other designs for factory mass production reactors)
Nuclear power (2600 TWH/year) has already displaced 20% of fossil fuel electricity usage.
South Korea has 4 year construction times for the latest gen 3.5 reactors built from about 200 modules.
South Korea is developing annular fuel uprates from MIT which have the potential for increasing existing nuclear power plant power by 50%. South Korea is pursuing a cheaper version which minimizes the changes to the plant and just changes the fuel rods. About 20% power boost. Can be combined with existing extended power uprates and plant operating life extensions.
Deeper burn reactor tech is being developed.
Business as Usual is to have the world to increase 20-40 million barrels per day the oil usage. So any plan has to slow and then reverse that trend. currently the world uses about 300 TWH of wind power
Solar energy levels will grow from 0.012 quadrillion Btu (quads) in 2010, to 0.018 quad in 2011 (in the USA which uses about 100 quad of energy from all sources. About 80% from fossil fuel. Wind power will grow by 31% by next year in the utility sector, from 0.909 to 1.189 quad
