Energy Annual Power TV use Power Use by per Use * Average square Size inch 0.23 101 192.6 CRT watt watts kWh/year DLP and 0.14 245 467.2 rear watt watts kWh/year 0.27 144 274.6 LCD watt watts kWh/year 0.36 361 688.4 Plasma watt watts kWh/year *Annual power use is calculated by multiplying power use with hours of television use per year. According to PG&E’s CASE study annual hours of use per television are 1907. PG&E estimates that the existing stock of televisions is made up of 63 percent CRT, 30 percent LCDs, 5 percent plasma flat screen, and 2 percent DLP. The July 8 2009 revised PG&E study estimates the average television use to be 1907 hours per year. Table 4 shows the estimated total energy consumed in California per year by each type of television technology.

Summing the energy consumption for all television types, the estimated statewide total energy use attributable to televisions is an estimated 8,772.3 gigawatt hours/year.
