EIA Annual Energy Outlook 2008 projects faster growth for renewables
The U.S. Department of Energy's Energy Information Administration (EIA) has released the early edition of the Annual Energy Outlook 2008, in which it is projecting renewable energy to experience 23 per cent faster growth between now and 2030 than previously anticipated. The EIA's latest outlook foresees renewable energy providing 12.2 quadrillion Btu ('quads'; 1 quad = 1055 Petajoules) of energy by 2030, up from only 9.9 quads in last year's outlook.
Total share
For comparison, total U.S. energy use was 100 quads in 2006 and is projected to increase to 123.8 quads by 2030. The EIA projections include hydropower, which is expected to increase from 2.89 quads in 2006 to 3 quads in 2015, staying level after that. In contrast, biomass energy is projected to increase from 2.97 quads in 2006 to 5.52 quads in 2030, a 86% increase, becoming by far the largest renewable energy source. Other renewables likes bioenergy from biogenic municipal waste, solar and wind power are projected to increase from 0.88 quads in 2006 to 2.49 quads in 2030 (graph 1, click to enlarge).
The early release of the AEO2008 does not include consideration of the recently adopted Energy Bill, which boosts biofuels massively (an estimated 3.1 quads by 2022). Note also that this is just the EIA's 'reference case', often characterized as the 'business as usual' scenario; a full EIA report examining alternative scenarios and taking into account the new Renewable Fuel Standard, will be released early in 2008.
Electricity
Breaking down the numbers for electricity production, hydropower is to remain the largest sector but doesn't grow much beyond its established share (0.2% capacity growth per year). Of the 'new' renewables, geothermal power generation is expected to increase to 27.96 billion kWh by 2030, up from 14.69bn kWh now.
Power generated from wood and other biomass is expected to increase nearly ninefold to 95.87bn kWh by 2030. Combined with power from biogenic municipal waste bioenergy is set to become the largest of the new renewables with a total annual output of 134.93 bn kWh (graph, click to enlarge). Co-firing biomass with coal is growing fastest at nearly 15.2% per year, while the use of biomass in dedicated power plants grows at 6.3% per annum.
Solar thermal power generation is expected to increase more than fourfold but remains marginal in absolute output, at 2.18 bn kWh by 2030. Likewise grid-connected solar power, which provided a miniscule share of the country's power in 2006, is projected to experience a 73-fold increase but remains very small with a total output of 0.96 bn kWh in the centralized electric power sector and with 4.51 bn kWh in decentralized, residential systems.
Wind power is projected to experience a fivefold increase to 134.35bn kWh in the centralised electric power sector and with a tiny share in decentralised systems (0.40bn kWh). The EIA does not project any significant offshore wind power in its reference case.
Combined, residential and commercial use of geothermal heat pumps, solar hot water, and solar and wind power are expected to contribute only 0.17 quads by 2030:
energy :: sustainability :: nuclear :: renewables :: biofuels :: biomass :: bioenergy :: wind :: solar :: geothermal :: hydropower ::
Nuclear power is set to grow relatively slowly with 100.2GW of installed capacity today to 118.8 GW in 2030, an annual capacity growth of 0.7%.
Overall, the EIA report projects higher oil prices in the future, although it anticipates that oil prices will gradually decline to a low of $58 per barrel in 2016. After that, oil prices steadily escalate back to today's prices by 2030, due to an increasing reliance on 'higher cost supplies'.
This also retards the growth in U.S. energy use, which increases at 0.9% per year in the reference case. And with our increasing reliance on high-tech devices, electricity use increases faster than total energy use, growing at an average annual rate of 1.3%.
