Today’s
Update…..
Computer
Energy Consumption:
Our
Team recently logged the energy usage of a desktop PC to determine
energy usage levels in different operational modes.

*Energy
usage of the computer will fluctuate during use, as the hard drive
is accessed. The figure recorded here is the baseline usage.
Based
on this information the following scenario was calculated:
| A.
Computer and Screen always on |
860
kWh (Rs.2900)/yr |
| B.
Computer always on, screen on during work hours* |
420
kWh (Rs.1650)/yr |
| C.
Computer and Screen on during work hours |
200
kWh (Rs.1050)/yr |
| D.
As for C with screen sleep mode set to 15 minutes |
150
kWh (Rs.800)/yr |
| E.
As for D with standby mode set to 1 hour |
130
kWh (Rs.650)/yr |
*work
hours estimated at 40 hours per week.
From
the above it can be seen that the simple act of turning a computer
screen off after hours will save about Rs.1250/- per year per
PC, with an additional Rs.600/- a year saved if the computer itself
is turned off.
Further,
savings can be made by enabling the sleep mode on the computer
screen. When in this mode the screen only uses 4% of that when
in operation. Setting the sleep mode to enable after 15 minutes
of inactivity could save another Rs.250/- per year, more if this
mode is used to power down the screen after hours. Remember, screen
savers do not save energy as they continue the screen running.
The sleep mode will perform the same function of protecting screen
life as well as save energy.
The
computer itself can also be set to either power down the hard
drive after a set period of time (saving 14% of computer energy
use) or go to standby mode (an 86% reduction). By enabling both
the screen sleep mode and the computer standby an overall saving
of about Rs.2250/- per year (per computer) can be achieved, as
well as an 85% reduction in electricity use. These functions are
easily enabled and once in place will deliver ongoing savings
without you having to worry about turning your computer off all
the time.
A
recent survey of several work areas found that for about 40% of
computers energy savings could be achieved through better practices.
Better computer energy management helps your area through energy
cost savings and the environment will benefit as well.

BEE
(www.bee.nic.in) Tips on
Lighting Systems
| LIGHTING
SYSTEMS |
|
| 01 |
One
of the best energy-saving devices is the light switch. Turn
off lights when not required. |
| 02 |
Many
automatic devices can help in saving energy used in lighting.
Consider employing infrared sensors, motion sensors, automatic
timers, dimmers and solar cells wherever applicable, to switch
on/off lighting circuits. |
| 03 |
As
for as possible use task lighting, which focuses light where
it's needed. A reading lamp, for example, lights only reading
material rather than the whole room. |
| 04 |
Dirty
tube lights and bulbs reflect less light and can absorb 50
percent of the light; dust your tube lights and lamps regularly.
|
| 05 |
Fluorescent
tube lights and CFLs convert electricity to visible light
up to 5 times more efficiently than ordinary bulbs and thus
save about 70% of electricity for the same lighting levels.
|
| 06 |
Ninety
percent of the energy consumed by an ordinary bulb (incandescent
lamp) is given off as heat rather than visible light.
|
| 07 |
Replace
your electricity-guzzling ordinary bulbs (incandescent lamps)
with more efficient types. Compact fluorescent lamps (CFLs)
use up to 75 percent less electricity than incandescent lamps.
|
| 08 |
A
15-watt compact fluorescent bulb produces the same amount
of light as a 60-watt incandescent bulb. |
