If you’ve taken the effort to observe the streets & roads as you commute or zip around in this land scarce island, on the roads in before sunrise & after sunset, you’ll come to realize that there are more street lamps than trees along the roads & sidewalks… and there are continuous lines of lighting in tunnels & on the highways.
It comes across as ironic where the local authorities have not done enough to manage the energy wastage on simple amenities such as roads. You will realize that the amount of light emitted from High Power Sodium street lamps (approx 400-1000w each) lined continuously on the roads suffice to make the headlights redundant.
The concept of needing to fulfill certain Lux levels (approx 30-50lx) on the roads is a safety requirement, but failure to realize that Color Rendering Index (CRI) plays an important role for color psychology in enhancing road users’ alertness really amazes me.
As I’ve illustrated in an earlier commentary on the matter of concern, its been proven that High Discharge Metal Halide lamps provide better CRI in keeping road users awake, and enhances their ability in gauging distances, debris and/or hazards, while the High Power Sodium lulls them to sleep at the wheel.
Further to add, the number of street lamps required for High Discharge Metal Halide can be reduced by approximately 3-5% on some stretches, and can even be reduced to 5-7% on some other stretches. Such aggregate savings may seem insignificant at a glance, but when multiplied by the number of days in a year, and again over a decade, is relatively significant.
Travelling around the region, seeing what’s been implemented & done in neighboring developing countries have truly been enriching, and in some cases floored me. It’s apparent that the authorities in these countries are better aware of the burden on the state, where amenity lighting is concerned. Stand alone Solar powered post top LED fixtures for walkways, alternate High Discharge Metal Halide & High Power Sodium on roads & highways to reduce the number of lighting points, LED bollards & step light etc, just to cite a few.
“Eventually every country will have to consider nuclear power because we have a completely carbon-based economy…” says former MM Lee of Singapore (in a recent dialogue at a local varsity)
In another commentary I posted before, we can’t deny that the increase of inhabitants will eventually lead to the hike in demands for energy, and so when population increases, the vacuum sharpens.
Nonetheless, as responsible beings on this resource (fast depleting) planet, we need to constantly question ourselves, if we’ve all as individuals endeavored enough to minimize energy consumption and/or wastage, or have we taken for granted that as long as the sun shall rise from the east, we shall have the abundance in energy.
Consider it correct to ssay that we shall have to consider nuclear energy eventually, but only if, little or nothing is done now to remedy the situation when it has yet to spin out of control.
We musn’t forget; this island doesn’t have the luxury of bottomless fossil fuel, is heavily reliant & at the mercy of the oil prices volatility as played around by the global cartel. Therefore, in the good name of pragmatism, it is all the more imperative that the authorities adopt more critical & frugal remedies to reduce the cost for the state.
