Annual Energy Outlook 2012
Release Date: June 25, 2012 | Next Early Release Date: January 23, 2013 | Report Number: DOE/EIA-0383(2012)
Issues in focus
| Assumptions | Integrated 2011 Deand Technology | Integraged High Demand Technologya | Integrated Buildings Best Available Demand Technologya |
|---|---|---|---|
| End-use equipment | Limited to technology menu available in 2011. Promulgated standards still take effect. |
Earlier availability, lower cost, and/ or higher efficiencies for advanced equipment. | Purchases limited to highest available efficiency for each technology class, regardless of cost. |
| Hurdle rates | Same as Reference case distribution. |
All energy efficiency investments evaluated at 7-percent real interest rate. |
All energy efficiency investments evaluated at 7-percent real interest rate. |
| Building shells | Fixed at 2011 levels. | 25 percent more improvement than in the Reference case by 2035. | 50 percent more improvement than in the Reference case by 2035. |
| Distributed and combined heat and power generation |
No improvement in technology cost or performance after 2011. Learning same as in the Reference case. | PV and wind costs, CHP cost and performance based on Advanced Case in EIA Technology reports.bLearning rates adjusted for advanced technologies. | PV and wind costs reduced by twice the difference between the Reference and High Technology costs. CHP based on Advanced Case in EIA Technology reports.b Learning rates adjusted for advanced technologies. |
| PC-related office equipment |
ENERGY STAR sales and enabling rates; LCD and laptop shares fixed at 2011 values. | ENERGY STAR sales and enabling rates. LCD and laptop shares higher than in the Reference case. | ENERGY STAR sales and enabling rates. LCD share approaches 100 percent. Laptop share higher than in the Reference case. |
| Non-PC Office Equipment |
Same as Reference case except for elimination of data center efficiency improvements. | Partial adoption of network power management for copiers, etc. Use of higher-efficiency power supplies for servers. |
Greater adoption of network power
management for copiers, etc. Use of higher efficiency
power supplies and continuous power management for servers. |
| Miscellaneous electricity |
Less efficiency improvement than in the Reference case for uninterruptible power supplies (UPSs), network equipment, elevators, and water services. |
Savings from high-efficiency UPSs and network equipment. | Greater savings from high-efficiency UPSs and network equipment. |
| aAll changes from the Reference case start in 2012 unless otherwise stated. bU.S. Energy Information Administration, Photovoltaic (PV) Costs and Performance Characteristics for Residential and Commercial Applications, Final Report (August 2010), The Cost and Performance of Distributed Wind Turbines, 2010-2035, Final Report (August 2010), and Commercial and Industrial CHP Technology Costs and Performance Data (June 2010). |
