節省能源 Saving Energy

將可熄滅的燈光熄滅,做法不但能改善光害,更能節省能源。以美國為例,據International Dark-Sky Association統計,有三成的戶外照明都是射向天上,白白浪費了高達十五億美元的電費、六百萬噸煤!因燃燒化石燃料而釋放的溫室氣體,進一步破壞我們的生態環境。

Saving energy and reducing light pollution can both be achieved by turning off useless lightings. According to the statistic from International Dark-Sky Association, 30% of outdoor lightings in U.S. are pointing upward. It wasted more than 1.5 billions of energy and 6 millions of coals! Global warming due to the combustion of fossil fuel is hence enhanced and degraded our environment further more.

香港的街燈數以十萬計,假如使用合適的燈罩,將照明集中照向地面,一方面改善光害,另一方面可以選用較低耗電量的燈泡,達至同等的照明效果,照明變得更有效率,能減少用電節省能源。

There are hundred thousand street lamps all over Hong Kong. Using suitable lampshades that focus light downward would improve the light pollution and save a huge sum on lighting costs by replacing light bulbs with lower power consumption. The increase of lighting efficiency means energy save.

在環保團體的鼓勵下,香港在2007年8月8日舉行了一次「熄燈行動」,召集市民集體熄燈數分鐘,以行動倡導環保和減少香港空氣污染的意識。可惜港府擔心行動會影響商界和旅遊業,沒有響應熄燈行動。

Hong Kong environmental organizations conducted a "Turning Off lightings" campaign on 8 August 2007. This campaign invited people to turn off their lightings at night for several minutes. The campaign also awakened people on environmental protection and serious air pollution issues of Hong Kong. The government however was not support the campaign and worried that the campaign will affect the commercial activities and tourism.

外國的「熄燈行動」反應較好,例如於2007年3月在澳洲悉尼進行的Earth Hour行動,結果有超過二百萬悉尼市民將照明關閉一小時,成功將悉尼市的用電量減少10.2%,及推廣減少全球暖化的訊息。

Overseas "Turning Off lightings" campaigns had good responds on the contrary. The "Earth Hour" campaign, for example, in Sydney in March 2007 successfully invited 2 millions people turned off their lightings for an hour at night. The campaign resulted in 10.2% of reduction in energy consumption and promoted the messages of prevent global warming.

既然我們已懂得如何保護大自然,少用膠袋節約用電用紙,以上減少光害的做法沒有理由不執行。

We know how to protect our natural environment by avoiding use of plastic bags, saving electricity and paper. We should follow the ways to reduce light pollution as well.
