The International Energy Agency says in areport that China's policy shift to develop green energy projects will reduce global greenhouse emissions by 2020. Lower economic growth worldwide and thefaster development of green energy will reduce the emissions by 5% by 2020. Instead of recent growth in emissions the lower economic growth will lower greenhous emissions by 3% this year.

The Supreme Court ruling on EPA mercury regulations gives smaller plants with coal fired plants more leeway in installing scrubbers. Large companies have already committed to installing scrubbers for coal fired plants. Regulations are only one reason for the shift to natural gas from coal. Lower prices of natural gas and increasing supplies are a major reason. The U.S. will reduce dependence on coal for energy from 39% to 36% in 2015, with natural gas increasing from 27% to 31%, and renewable solar wind energy making up about 13%, according to EIA.

The Obama administration is pushing for new U.S. fuel efficiency standards of 56.2 mpg by 2025. In May 2009 President Obama announced domestic car and light truck fuel efficiency standards of 35 mpg by 2016. Europe is expected to reach fuel efficiency of 60 mpg by 2020. This would still leave Europe considerably ahead of the U.S. in fuel efficiency for automobiles, but the gap would be much smaller. For the last several decades the U.S. has fallen sadly behind Europe and Japan in fuel efficiency. The perception of poor fuel efficiency hurt the automakers badly during periods of high fuel prices and when buyers were facing difficult economic choices. The automakers are beginning to grasp this fact. Mark Reuss, president of General Motors, commented that- "it's very challenging, but its upto us engineers to provide high value to the customer and support the environment." This is an issue that has serious national and global implications as it affects the future prices and demand for oil, emissions, and future economic growth. It would also bring the U.S. in line with Europe and Japan when it comes to fuel efficiency of automobiles. ...

Fuel efficiency rules require average fuel efficiency in the U.S. of 35 mpg by 2016. The debate is now on what to do for 2017 to 2025. New technology such as the P2 systems for hybrids already used in VW, Nissan and Hyundai vehicles makes a 20% increase in fuel efficiency possible. Large investments are being made to bring new technology to bear on increasing fuel efficiency significantly. Government agencies are looking at different scenarios by which the new fuel economy standards beyond 2017-2025 could be set between 47 mpg and 62 mpg. An additional factor is the reduction in greenhouse gas emissions- at 47 mpg the reduction would be 3%, at 62 mpg the reduction would be 6%. Another factor is how much the impact is on the cost of vehicles and reduced cost on gasoline. Here there is a wide range in the numbers for average mpg rules at 62 mpg- with EPA estimates at $2800-$3500 increase in vehicle cost and $5000 savings in fuel cost, Centre for Automotive Research estimates at $9790 increase in vehicle cost. The 62 mpg translates into "real world" actual efficiency of 45 mpg. In April 2011, 17 senators put out a letter of support for the 62 mpg proposal. There is a public value involved in this that is also significant- the reduced dependence on foreign oil means savings in defense expenditures in parts of the Middle East, and an economy that is less impacted by volatility in the price of oil. As this aspect of public value or benefits cannot be quantified easily even though they are significant, this may tend to be lost in the debate and the politics of fuel efficiency. For automakers there is significant marketing value in having a visible and strong presence in fuel efficient vehicles because of perception as forward looking- something that hurt Detroit carmakers in the last decade. During periods of gasoline prices at $5 a gallon this provides carmakers with an extra cushion of safety in securing car sales. Carmakers in one country such as the U.S. also have to worry about what carmakers in other countries such as Japan and Germany are doing- if the standards in the U.S. develop a gap compared to other countries developing advanced fuel efficiency technologies this poses significant risks because of the global nature of the automobile marketplace. See the group "Asleep at the Spigot" for more details on this. Many of these less quantifiable factors do not get the attention they deserve because they are significant from experience but not easily quantified. Throw into this the large unknown of what new technologies not yet developed lie ahead with a burst of effort by one country or another, which bring cost reductions at the same time - and the debate requires as much a good sense of what is the path offering the greatest advantages in years ahead than a pure exercize in numbers. ...
