Opposite from how many developed countries are struggling to make ends meet, Singapore has the capability to support businesses in adopting a 'Go Green' process. I'm sure going forward this would help the country be more competitive.
Energy prices are increasing everyday due to declining supplies of fossil fuels. The time to invest in renewable energy sources, identify equipments and technology that reduce consumption, creating process and standards to guide the proper and safe use of such technologies, should be carried out today.
One cannot deny the lowest hanging fruit to achieving better energy efficiency is changing from fluorescent to LED lightings. Supply and install is becoming low cost today compared to 3 years ago. Quality of LED lighting is relatively stable compared to 3 -5 years ago. With contractors more aware of how to install and replace LED lightings today, it has help minimise inefficiencies in the installation process.
Combining all the above, the break even benefit for using LED lighting would definitely be much faster today.
