This b ooklet conta ins information a nd idea s you will need to de velop and

implement an ene rgy efficiency s trategy.

We believe that targets of between 10 and 20% reduction in electricity use

can b e ac hieved by understanding how we use energy. We take energy

efficiency very serious ly and we want to he lp you s ave energy wherever poss ible.

We hope you find this guide us eful and toge ther with your Efergy Wireles s

Energy is a controllable cost!

In order to implement energy saving me asures and manage your energyconsumption, you need to understand how and where your energy is being

used.

Energy monitoring with easy-to-use electricity displays can help you maximise

energy efficiency and achieve savings of up to 20%

Create understanding... Save energy

Everyone needs to know why energy efficiency is important. Understanding

energy use c an b e the most c ost-effective way to s ave energy.

The amount of electricity consumed varies hugely according to size of home,

location, house type and the number of occupants. There are many variables

so it is often difficult to understand what you should be using and whether

what you use is very high o r low.

Do Som e res ea rch - Consult the Internet or a sk your

su pplier ho w mu ch you pa y for your fuel, and work

out your yea rly cos t. You the n have a b as e num be r

to work ag ainst.

Often your electricity bill doesn’t make it easy to predict how much you are

spending on electricity. Make a note of your daily average consumption and

estimate your yearly cost.

Power consumption is gauged by measuring in Watts (W) the amount of energy

a device consumes per hour, expressed in kilowatt hours (kWh).

For example a 100W incandes cent light bulb switched o n for ten hours wouldconsume 100W x 10Hrs will equal 1,000 watt-hours, or 1kWh.

Is your me ter reliab le?

Meter readings are used to calculate your bill. Therefore, before installation, all

meters mus t meet s tringent ac curacy requirements.

Once installed, meters are periodically chec ked by your supplier to ensure they

continue to give accurate readings. Meters are very rarely inaccurate.

Knowing how much e lec tricity you a re us ing a nd having the information in front

of you can make a rea l difference . Insta nt fee dba ck lets you ad just your

be haviour to suit. It is worth looking at how many watts an a pp lianc e us es ,

but more important how you might adjust your behaviour to sa ve money us ingthat device.

You c an us e the electricity usa ge m onitor to quickly estimate ho w much

electricity any de vice is us ing. For example, whe n you switch the kettle on,

within a few seconds you will see the instant power consumption displayed

jump up (typica l kett le wo uld co ns ume 2kW). This inc rea se will reflec t the

consumption of the kettle. Typically, a kettle might be turned on four times a

day for a two-minute b oil. That's only eight minutes a d ay, which me ans a tota l

daily consumption of 0.27kWh (2kW x 8min x 1hour / 60min = 0.27kWh).

A PC that's used for home entertainment and internet browsing might be

turned on for many hours at 12 0W. PC can be typically switched on for 40

hours a week or more, which works out at 4.8KWh per week. Unfortunately,

computing and home -entertainment eq uipment is not tagge d with the s ame

eas y-to-understand energy labe ls. For example, many wides creen p las ma TVs

consume more power than a fridge-freezer.

When you leave your home or office, it’s a good idea to check the display. It

will give you an idea of how much electricity you’ll be using even when you’re

not in. Perhap s you’ll be pe rsuad ed to s witch o ff the TV or com puter mo nitor,

Check the display before you go to bed. How much money will you spend

while you’re asleep? And what can you save by switching off an appliance?

Monitor how much money it costs you just to boil the kettle, or cook a meal.

Tes t out whether you ca n sa ve money and power by switching off applianc es ,

rather than leaving them on s tand -by. You might be surprise d how much energy

is wasted when some appliances are not turned off al together.

Remember that large savings can be made if you cut down how often you use

high wattage appliances and the length of time you use them (i.e. an electric

shower). These items include heaters, air conditioners and electric hot water

systems. Where possible, try to use energy efficient light bulbs and trade in

your spare fridge if you have one. When replacing old appliances or buying

new appliances, always purchase those with the highest energy efficiency

ratings.

opportunities.Try and lower the readings on the electricity usage monitor down to as low

a reading as you can, and then watch the numbers increase as you switch

devices back on. This will help you identify which devices use the most

electricity.

You might find that the se t of down- lights in the kitche n us es far more electricity

than you realised. This might be the incentive needed to switching them off.

A digibox may only use 50W of electricity, but if this is left on over 24 hours,

this adds up to 1,200W over 24 hours - 10% of your total daily use.

1. DON' T LEAVE APP LIANCES O N STAND-BY

TVs: On average, a traditional cathode ray tube (CRT) television set uses

100W of power when in use and a few Watts on stand-by. Newer LCD andplasma screens are higher users of energy, with the largest models consuming

up to 400 W when in use and 1 0W on stand-b y.

DVD players: Consumers can safely switch off most DVD players/recorders,

hard disk recorders or video recorders. They should not need to retune the

devices when they are switched b ack on o r have to contend with the dreaded

flashing clock as the machines usually retain their settings. However,

manufacturers recomme nd tha t som e s atellite TV receivers b e left on s tand-

by when not in use so they can receive updates .

Peripherals such a s p rinters and sca nners sho uld also be turned off when

not in use. Leaving unnecessary items on stand-by is said to cost eachhouseho ld a n average o f £50 a year.

More than 90% of the ene rgy that s tandard incandesc ent light bulbs use

is lost as heat. The next time a 60W incand esc ent bulb burns out, c onsider

using a 15W CFL (Compact Fluorescent Lamp). It provides the same

sides of the chart you will find week numbers. Week 1, for example, represents

the first wee k in J anua ry. Week 30 (2008) would rep rese nt the week s tarting

Use the Wireless Electricity Monitor to scroll through how much electricity

you have been using each week by looking at the history information mode.

Go to the weekly history mode. Push the
