PIER Annual kWh of TVs by Mode Standby force is comparable paying little respect to TV sort or size. More current TVs utilize significantly more vitality than more established ones. Bigger and more current advances (plasma & back projection) have a tendency to be utilized increasingly and are oftentimes part of a bigger excitement set up.

So… How much vitality does a screen saver save?Slide 26
Computers Average desktop PC framework draws 140W all things considered, an ENERGY STAR PC utilizes 70% less power than standard unit—however just if power administration components are enacted Major productivity picks up as far as interior force supplies; all the more coming Monitor represents around one a large portion of the utilization 17" shading screen utilizes around 35% more vitality than a 14" shading screen Laser printers draw around 33% of print force when on standby – 100W or so DOE PC cost number cruncher Check DOE & www.energystar.gov for extraordinary stuff on this.Slide 27

Simple Payback for Power Strips Using a standard electrical extension spared 0.5 kWh/day for amusement framework #1– around 183 kWh/yr Using an Occupancy Sensor strip in home office w/25W standby spared around 0.3 kWh/day – around 109 kWh/yr Is this huge? These two activities spared 292 kWh/yr At $.14/kWh this equivalents about $40/yr For a seven month payback!Slide 38
Power Strip Purchase Tips Get surge assurance and diminished vitality use. Details: clipping voltage (the amount of power will trigger it) of no less than 330 vitality scattering rating (the amount of power will make it come up short) of no less than 400 joules, reaction time of 10 nanoseconds or less www.alliantenergy.comSlide 39
Standby Power & Low Energy Homes The less vitality a home uses, the greater part of the aggregate vitality use standby force gets to be When power is site created—PV, wind, and so on.— diminishing standby burdens turns out to be considerably more vital. At 1-2 kWh/day (FSEC measured), standby force breaks even with 20% of PV yield for a 2 kW exhibit! Littler burden = Smaller framework = Lower costSlide 40
