Forum: Look into areas where energy consumption can be cut

It is reassuring that the Government is monitoring Singapore’s energy consumption in the light of the Middle East conflict (Ministerial committee to deal with supply shocks, price increases from Mid-East conflict: Shanmugam, April 4).

While I’m not suggesting that Singapore adopt the drastic measures seen in other countries, there are many areas across society where consumption can be reduced without imposing undue inconvenience.

First, there are too many lamp posts and lights along sheltered walkways in some areas. The authorities could consider switching off every alternate lamp post or dimming lighting levels, especially in locations with low human traffic.

Second, while digital display screens at Housing Board lift lobbies provide information, their continuous operation consumes electricity that could otherwise be saved. There is nothing wrong with reverting to traditional noticeboards to disseminate information. 

Third, wet markets and hawker centres often remain brightly lit long after business hours. Many wet markets close by noon, and many heartland hawker centres see significantly reduced activity by 8pm. Yet, lights and fans are frequently left running for hours after that. Ditto for privately run coffee shops, which are often too brightly lit as well.

Lastly, shopfronts and signboards are often left illuminated despite businesses having closed for the day. This is another area where simple discipline or policy guidelines could reduce unnecessary energy use.

More broadly, the Government should thoroughly review non-essential electricity consumption and implement targeted reductions where feasible. 

Singapore has been described by National Geographic as one of the countries most polluted by light, which is not something to be proud of.
