En­ergy ef­fi­cient bulb sales up

Matamata Chronicle - - Building -

Waikato res­i­dents are be­ing en­cour­aged to re­duce their homes’ en­ergy costs this win­ter by re­plac­ing old in­can­des­cent bulbs af­ter new data showed Ki­wis bought nearly 1.95 mil­lion en­ergy ef­fi­cient light bulbs from su­per­mar­kets last year.

The grow­ing num­ber of en­ergy ef­fi­cient light bulbs pur­chased in New Zealand has saved up to $4 mil­lion in en­ergy costs or the equiv­a­lent elec­tric­ity con­sump­tion of about 6000 homes, ac­cord­ing to the En­ergy Ef­fi­ciency and Con­ser­va­tion Author­ity (EECA).

EECA light­ing man­ager Bill Bran­der said the bulbs now make up 23 per cent of all light bulb sales, com­pared to 17 per cent in 2012.*

He said the in­crease in en­ergy ef­fi­cient bulb sales is im­por­tant be­cause of the sig­nif­i­cant sav­ings to house­holds from re­plac­ing old fash­ioned bulbs with en­ergy ef­fi­cient mod­els.

‘‘Re­plac­ing six in­can­des­cent bulbs in high-use ar­eas with ef­fi­cient bulbs can save $120 a year, even af­ter you fac­tor in the cost of the bulbs. The ef­fi­cient bulbs also last much longer,’’ Bran­der said.

Bran­der said the end of day­light sav­ing is the time when Ki­wis tra­di­tion­ally re­place failed bulbs and he en­cour­ages house­holds to in­stall more en­ergy ef­fi­cient light bulbs to make more sav­ings.

‘‘Light­ing use typ­i­cally dou­bles in au­tumn and win­ter be­cause people are spend­ing more time at home and the nights are longer,’’ he said.

‘‘Light­ing makes up about 12 per cent of a home’s elec­tric­ity bill and the aver­age home has about 30 light bulbs – so in­stalling en­ergy ef­fi­cient bulbs is a very easy way to re­duce en­ergy use.’’

Stan­dards in­tro­duced in 2012 mean all CFL en­ergy ef­fi­cient light bulbs must meet per­for­mance re­quire­ments and the top per­form­ing bulbs have the blue EN­ERGY STAR®, Bran­der said.

‘‘In the past people were con­cerned about the limited range of op­tions. There’s now a range of at­trac­tive en­ergy ef­fi­cient bulbs in warm and cool tones that will work now in most sit­u­a­tions,’’ Bran­der said. Key en­ergy ef­fi­cient light bulb facts: In 2012, ef­fi­cient light bulbs made up 16.8 per cent of all bulb sales – in 2013 that has grown to 22.9 per cent

In 2012, 1.49M ef­fi­cient light bulbs were sold, in 2013 that in­creased to 1.95M (+454k)

In 2012, 7.40M in­ef­fi­cient light bulbs were sold - in 2013 that de­creased by 12 per cent to 6.54M (-860k)

To­tal light­bulb vol­ume there­fore de­creased by -5 per cent (-406k) over that pe­riod
