Summary Reader Response: Draft 1
Kok (2021)'s article informs the public about the implementation of a project done by Go-Ahead, a bus operator in Singapore. In order to utilise solar energy to reduce fuel consumption and carbon emission, Go-Ahead has installed 1.6mm thick, flexible, and shatterproof solar panels on two diesel-powered buses in Singapore, over a 6-month trial period.
The two combined solar panels generate up to 1,000 watts of energy to charge the buses' batteries, thereby reducing the batteries' reliance on the alternator. This lessens the strain on the buses' engines, saving 1,400 liters of diesel, and reducing 3,700 tonnes of carbon emissions, per bus, annually. These figures are extrapolated from data in the United Kingdom, but the project is expected to do better here—given Singapore’ sunny climate.
Go-Ahead used lightweight panels (i.e total of 20kg), that are three times thinner as compared to conventional ones. Partnering with the Land Transport Authority, the buses have undergone safety assessments and are approved for public road trials. Evaluation regarding the panels’ ability to withstand high temperatures and daily washing would also be tested.
From the expenses saved due to fuel reduction, Go-Ahead expects to recuperate the costs of the trial within four years. If successful, more solar panels may be installed on Singapore buses.
