The reference case in the Energy Information Administration’s (EIA) early release edition of Annual Energy Outlook 2007 (AEO2007) projects more biofuels (both ethanol and biodiesel) consumption, growth in coal-to-liquids (CTL) capacity and production, growing demand for unconventional transportation technologies, growth in nuclear capacity and generation, an expansion in coal-fired power generation and accelerated improvements in energy efficiency throughout the economy.
AEO2007 projects ethanol use increasing from 4 billion gallons in 2005 to 14.6 billion gallons (about 8% of gasoline consumption by volume) by 2030. Only 300 million gallons of that are projected to come from cellulosic biomass sources; the rest will come from corn. Biodiesel use will also grow rapidly to 400 million gallons in 2030, up from 25 million gallons in 2005. The EIA expects 5.7 billion gallons of CTL fuels by 2030.
As a result, petroleum consumption is projected to only increase 20% by 2030, while the total energy consumption for transportation increases by nearly 40%.
Projected ethanol consumption in 2012 far exceeds the 7.5 billion gallon requirement of the Renewable Fuel Standard enacted as part of the Energy Policy Act of 2005 (EPACT 2005).
The AEO2007 reference case also reflects growing penetration by non-gasoline technologies. Sales of flex-fuel vehicles, which are capable of using gasoline and E85, are projected to reach 2 million per year in 2030. Sales of hybrids, including both full and mild hybrids, are also projected to reach roughly 2 million per year in 2030, while diesel vehicles sales reach 1.2 million. Including other unconventional vehicle technologies (e.g., gaseous, electricity, fuel cells), in total they account for almost 28% of projected total new light-duty vehicles sales in 2030, up from just over 8% in 2005.
The EIA sees only marginal gains in fuel efficiency in the new light-duty fleet, however, with an increase to an average 29.2 mpg US by 2030 (33.7 mpg for cars, 26.5 mpg for light trucks).
Despite the projected rapid growth of biofuels and other non-hydroelectric renewable energies and the expectation of the first new orders for nuclear power plants in more than 25 years, oil, coal, and natural gas are nonetheless projected to provide roughly the same 86% share of the total US primary energy supply in 2030 as they did in 2005 absent changes in existing laws and regulations.
This reflects a situation in which rapid growth in the use of biofuels and other non-hydro renewable energy sources begins from a very low current share of total energy use, the share of a growing electricity market supplied from nuclear power falls despite projected new plant builds, and hydroelectric power production, which accounts for the bulk of current renewable electricity supply, is stagnant.

Carbon dioxide emissions from energy use are projected to grow at an average annual rate of 1.2% per year, from 5,945 million metric tons in 2005 to 7,950 million metric tons in 2030, reflecting growth in fossil fuel demand. The carbon dioxide emissions intensity of the US economy is projected to fall from 538 metric tons per million dollars of GDP in 2005 to 353 metric tons per million dollars of GDP in 2030, an average decline of 1.7% per year.
Nuclear. The AEO2007 reference case projects that total operable nuclear generating capacity will grow to 112.6 gigawatts in 2030, including 3 gigawatts of additional capacity, and 12.5 gigawatts of new capacity stimulated in part by EPACT2005 tax credits and rising fossil fuel prices. Total nuclear generation is projected to grow from 780 billion kilowatthours in 2005 to 896 billion kilowatthours in 2030, but the nuclear share of generation falls from 20 percent in 2005 to 15 percent in 2030.
Natural gas. Natural gas consumption is projected to grow to 26.1 trillion cubic feet (tcf) in 2030, well down from projected consumption of 30 tcf or more that had been included in the AEO reference case only a few years ago. Much of this change results from projected natural gas prices that significantly cut the expected growth natural gas use for electricity generation over the last decade of the projection period. In the AEO2007 reference case, overall natural gas consumption is almost flat between 2020 and 2030, as growth in residential, commercial and industrial consumption over this period is nearly offset by a decline in projected gas use for electricity generation.
Coal. Coal remains the primary fuel for electricity generation. The coal share of generation increases from 50% in 2005 to 57% in 2030. The natural gas share of generation increases from 19% in 2005 to 22% around 2016, before falling to 16% in 2030. Over the entire period from 2005 to 2030, 156 gigawatts of new coal-fired generating capacity is projected to be added in the AEO2007 reference case, including 11 gigawatts at CTL plants and 67 gigawatts at Integrated Gasification Combined Cycle plants. Possible future changes in energy or environmental policies could significantly impact these projected generation shares.
Other highlights of the AEO2007 include:
Total energy demand is projected to increase from 100.2 to 131.2 quads between 2005 and 2030, an average annual increase of 1.1%, in a scenario where the US gross domestic product (GDP) grows at an average annual rate of 2.9%.
Real world crude oil prices (2005 dollars), which are expressed in terms of the average price of imported light low-sulfur crude oil to U233 refiners, are projected to decline gradually from their 2006 average level through 2015 as new supplies come to market in response to the higher prices and expanded exploration and development investments. After 2015, real prices begin to rise as demand continues to grow and higher cost supplies are brought to market. In 2030, real world crude oil prices are projected to reach over $59 per barrel in 2005 dollars, or about $95 per barrel in nominal dollars.
The net import share of total liquids supply, including crude oil and refined products, drops from 60% of total liquids supply in 2005 to 54% in 2009 and then increases, reaching 61% in 2030. Imports of refined petroleum products account for 20 percent of total net imports in 2030.
Average real natural gas wellhead prices are projected to fall from today’s high levels to just under $5 per thousand cubic feet (mcf) (2005 dollars) by 2013 as increased drilling brings on new supplies and new import sources become available. After 2013, natural gas wellhead prices are projected to increase gradually, to about $6 per mcf in 2030 (equivalent to $9.63 per mcf in nominal dollars).
Major contributors to growth in natural gas supply include LNG imports, the completion of an Alaskan natural gas pipeline in 2018, and domestic unconventional production. Net LNG imports are projected to increase from 0.6 tcf in 2005 to 4.5 tcf in 2030, Alaskan production reaches 2.2 tcf by 2030, and unconventional production grows to 10.2 tcf in 2030, accounting for 50% of domestic US natural gas production in 2030
- Projected real minemouth coal prices falls from $1.15 per million Btu ($23.34 per ton) (2005 dollars) in 2005 to $1.08 per million Btu ($21.51 per ton) in 2019 as prices moderate following the rapid run up that has been seen in last few years and relatively low-cost western mines continue to capture a larger share of the market. After 2019, the growing use of coal in new power plants leads to a gradual increase in coal prices. They reach $1.15 per million Btu ($22.60 per ton) in 2030.
After reaching a peak of 8.3 cents per kilowatthour (kwh) (2005 dollars) in 2006, average delivered real electricity prices decline to a low of 7.7 cents per kwh in 2015 and then increase to 8.1 cents per kwh in 2030. Without adjustment for inflation, average delivered electricity prices in the AEO2007 reference case are projected to reach 13 cents per kwh in 2030.
Consumption of renewable fuels is projected to grow from 6.5 quads in 2005 to 10.2 quads in 2030. More than 50% of the projected demand for renewables is for grid-related electricity generation, including combined heat and power, and the rest is for dispersed heating and cooling, industrial uses, and fuel blending.
