There are a few lessons to glean from the Surprise Index, which I was only made aware of this week. First, predictions are often reported as news. They’re not. They’re predictions, and they’re almost always wrong. Full disclosure: I’ve been as guilty as anyone for breathlessly passing along predictions without the qualifying them as conjecture. Second, to be fair to the analysts, sometimes the first draft of the economic figures aren’t any better than the predictions. A great example: We initially estimated GDP falling 3.8% in the last three months of 2008. Instead, it fell nearly 9%. That’s a horrible miscalculation that had a real impact on decisions made by Congress and the Federal Reserve to fix the economy. I wonder what the Economic Surprise Index would say about first readings of GDP and unemployment numbers.

A Future of Fossil Fuels
EIA’s latest numbers shows a continuous growth in energy consumption, led by China and India.
Full Story: Technology Review
Since I have been working in the transport industry for some years and realized that energy people in general had very shallow understanding of transportation. E g does this projection include that person transportation actually increase exponentially in relation to GDP during certain development phases of a country or region? Andreas Schäfer writes about this in Long-Term Trends in Global Passenger Mobility (a republished/revised report from 1997).
If these projections assume linear growth of personal transportation when in fact it will turn out to be exponential, they might be radically underestimating the energy consumption for the decades to come.
Some key findings:
- China and India lead the growth in world demand for energy in the future. The economies of China and India were among those least affected by the worldwide recession. They continue to lead world economic growth and energy demand growth in the Reference case. In 2008, China and India combined accounted for 21 percent of total world energy consumption. With strong economic growth in both countries over the projection period, their combined energy use more than doubles by 2035, when they account for 31 percent of world energy use in the IEO2011 Reference case (Figure 1). In 2035, China’s energy demand is 68 percent higher than U.S. energy demand.
- Renewable energy is projected to be the fastest growing source of primary energy over the next 25 years, but fossil fuels remain the dominant source of energy. Renewable energy consumption increases by 2.8 percent per year and the renewable share of total energy use increases from 10 percent in 2008 to 15 percent in 2035 in the Reference case. Fossil fuels, however, continue to supply much of the energy used worldwide throughout the projection, and still account for 78 percent of world energy use in 2035 While the Reference case projections reflect current laws and policies as of the start of 2011, past experience suggests that renewable energy deployment is often significantly affected by policy changes.
- Natural gas has the fastest growth rate among the fossil fuels over the 2008 to 2035 projection period. World natural gas consumption increases 1.6 percent per year, from 111 trillion cubic feet in 2008 to 169 trillion cubic feet in 2035. Unconventional natural gas (tight gas, shale gas, and coalbed methane) supplies increase substantially in the IEO2011 Reference case—especially from the United States, but also from Canada and China.
- World oil prices remain high in the IEO2011 Reference case, but oil consumption continues to grow; both conventional and unconventional liquid supplies are used to meet rising demand. In the IEO2011 Reference case the price of light sweet crude oil (in real 2009 dollars) remains high, reaching $125 per barrel in 2035. Total world petroleum and other liquids fuel use increases by 26.9 million barrels per day between 2008 and 2035, but the growth in conventional crude oil production is less than half this amount at 11.5 million barrels per day, while production of natural gas plant liquids increase by 5.1 million barrels per day, World production of unconventional resources (including biofuels, oil sands, extra-heavy oil, coal-to-liquids, and gas-to-liquids), which totaled 3.9 million barrels per day in 2008, increases to 13.1 million barrels per day in 2035
