In a previous article, the potential negative impacts on avian biodiversity if plans for the construction of Cross Island Line (CRL) were to follow through were highlighted. In this update, Tan Hui Zhen and Shermaine Wong turn their focus to other biodiversity that reside in the MacRitchie forests - the non-avian fauna and often overlooked flora of the Central Catchment Nature Reserve (CCNR).
Civic society and NGOs managed to convince the Singapore government to hold off its plans to run a new MRT line through a biodiverse nature reserve until a comprehensive assessment on environmental impacts has been made. Tan Hui Zhen and Shermaine Wong report.
The inter-agency Electric Vehicle (EV) Taskforce, led by the Energy Market Authority (EMA) and the Land Transport Authority (LTA), announced the launch of the electric vehicle test-bed in Singapore on 25 June 2011. It was also revealed for the first time that Daimler South East Asia (SEA) Pte. Ltd has joined the test-bed, and will bring in 20 smart fortwo (ed) vehicles available for lease under the EV test-bed from July 2011.
With over 50,000 bikes available to rent, Hangzhou in China is aiming to reduce pollution, cut congestion, and keep its people healthy – all while making a profit!
New rules for smaller engines and improved energy-recovery systems mean that Formula One racing cars will get much more fuel efficient, and quieter, within the next two seasons.
Andrew Porter takes a closer look at how energy travels from the grid to the road, and argues that electric cars are not necessarily more energy efficient compared to fossil-fuel powered cars. Electricity generation needs to be re-examined to gain greater energy efficiencies.
How soon will we see people driving sustainable motorcars that reduce the impact on fossil fuels and reduce pollution? While many people assume, and hope, that the next generation motorcar will be powered either from a rechargeable battery, or an internal combustion engine using bio-fuels, there are problems associated with these methods. Andrew Porter looks into the sustainability issue of bio-fuels to power internal combustion engines, and presents the bright prospect of fully-optimised electric cars inspired by the old diesel electric railway locomotive.
Singapore has aced in many areas. But when it comes to embracing renewable forms of energy sources though, Singapore is terribly late in the game.
Much has been said about next generation motorcars and the influx of bio-fuels, petrol electric hybrids, pure electric, hydrogen power and so on. Still, just how much improvement they make to the environment on a total carbon footprint basis remains debatable. But we can do something about what we have now. This article looks at what can be done to improve existing motorcars – both old and new - in terms of fuel efficiency.
Most people think of the internal combustion engine as being the thing that powers cars. But just as many are used for railway trains, ships, planes and more. Although carmakers are looking at alternatives like fuel cells, battery power or even biofuels to run hybrids, there are still plenty of vehicles with plain old internal combustion engines – so is there anything that can be done to improve it that will help lessen environmental impacts?
