10 energy efficiency facts from EPRI

Palo Alto, CA, Dec. 15, 2008 — The Electric Power Research Institute Inc. (EPRI) conducts research and development for the global electricity sector and energy efficiency is one of their key research topics. The institute’s efficiency research programs address key industry issues such as:

* Understanding the impact of energy efficiency on household and building energy use.
* Reaching the full potential of efficiency?
* What kind of infrastructure is required for demand response or end use technologies?

EPRI is conducting more than 20 projects that can help utilities assess technologies, invest in infrastructure and design more efficient systems. The following 10 energy efficiency facts were uncovered in their research:

1) If every household in the United States used one digital photo frame and operated it 24 hours a day every day for a year, it would require five 250-megawatt coal-burning power plants to supply the power for these devices. Each unit requires approximately eight watts of power, or approximately 90 kWh per year.

2) Research has documented that residential consumers can reduce energy consumption by 5—15 percent by installing in-home displays that provide real-time energy demand and energy price information.

3) EPRI has estimated that deployment of a smart grid could potentially reduce annual U.S. energy consumption by 56 to 203 billion kWh in 2030, corresponding to a 1.2 to 4.3 percent reduction in projected retail electricity sales in 2030.

4) EPRI has estimated that the combined deployment of seven smart grid technologies could reduce CO2 emissions by an estimated 60 to 211 million metric tons in 2030.

5) The EPA estimates that 1.5 billion power supplies are used in various devices in the United States, constituting about 300 billion kWh, or approximately 11 percent, of national annual electricity usage.

6) According to DOE’s Annual Energy Outlook 2008 report, electricity consumption from 2005 to 2030 is projected to grow by 27 percent in the residential sector, 52% in the commercial sector, and 5% in the industrial sector.

7) Lighting accounts for 28 percent and 16 percent of all electricity used in commercial and residential sectors, respectively.

8) Data centers accounted for about 61 billion kWh in 2006–nearly 1.5 percent of total electricity use.

9) Two billion dollars per year is being spent in state and utility administered energy efficiency programs in residential, commercial and industrial facilities.

10) If the energy efficiency of our generation, transmission and distribution system can be improved by 10 percent, the kilowatt-hours saved would be enough to power approximately five million homes per year.
