Solar Powered, Sunny Singapore

Our nation is making big plans to harness more power from the sun. Here’s the lowdown on how we’re gearing up for solar.

As the Earth continues to experience climate change, countries all across the globe are ramping up their efforts to employ cleaner energy sources.

Singapore is no different, having taken measures that date back to the early 2000s, and numerous plans for the future. Out of the myriad non-fossil fuel energy sources, solar energy will become one of the Lion City’s most important renewable options in the future (proving that not only Superman can harness the power of the sun).

Read on for the scoop on why solar power is the most promising source of renewable energy for our sunny island, the various projects and goals that have been undertaken, and ways that you can be a game changer in the fight for our environment.

Strengthening flood protection in Singapore

It’s easy to be disheartened when one hears about the impacts of climate change on our environment.

On TV, we’re confronted with the devastation of fires in the Amazon and Australia, as well as the severe flooding that has hit Venice and Jakarta. Films like An Inconvenient Truth and The Day After Tomorrow run the gamut from factual to fantastically frightening, but hammer home the anxiety we’re feeling about the consequences of harming Mother Nature.

Closer to home, Singapore has experienced its own share of extreme weather too, such as  intense rainfall events that lead to more frequent flash floods, and prolonged dry spells that threaten our water security. It is estimated that it may cost $100 billion dollars over the next century to protect ourselves against rising sea levels in the future.

The nature of Singapore’s geography makes our nation vulnerable to intense storms and flash floods—In January 2018, a storm led to half a month’s worth of rainfall in just four hours.

It’s not all doom and gloom, however. Governments, enterprises and activists all over the world are stepping up their efforts to save the planet, leading to ingenious efforts in mitigating and adapting to climate change.

Singapore has long been mindful of the perils of climate change. Over the years, we’ve embarked on a series of ambitious solutions that will weather us through the storm. One such undertaking is the Stamford Detention Tank (SDT) and Stamford Diversion Canal (SDC), a project that’s taken four years to construct.

The Stamford Detention Tank and Canal—A 101 guide

Remember what it was like to run that daunting 2.4 kilometres for your IPPT in school or National Service? Imagine a massive, twin underground tunnel and canal of that length running beneath the earth.

This winding, underground facility — the Stamford Diversion Canal — connects the Stamford canal with the Singapore River. Together with the Stamford Detention Tank, a sprawling, 0.5ha tank with the capacity of 15 Olympic-sized swimming pools, they work as a system to alleviate floods in the Orchard Road belt.

During heavy rainfall, the Stamford Diversion Canal will divert rainwater from upstream of the catchment into the nearby Singapore River, while the Stamford Detention Tank will store excess rainwater, so less of it flows into the Stamford Diversion Canal.

This epic project took four years, two million man-hours and $227 million to complete, as part of a continual effort to strengthen flood resilience in Singapore.

Shielding Singapore against rising waters

The Stamford Detention Tank and Stamford Diversion Canal are just a few of Singapore’s many ongoing efforts to adapt to climate risks.

Here are other measures that have been put into place to protect Singapore against flash floods.

Upgrades to the Bukit Timah First Diversion Canal

The Bukit Timah First Diversion Canal, which has been widened and deepened, can now divert 30 percent more rainwater away from the flood-prone Upper Bukit Timah catchment, thanks to a $300 million upgrading project that was completed in 2019.

Island-wide drain improvement

Since 2011, Singapore has spent more than $1.9 billion on drainage improvement and upgrading works, with an estimated additional $200 million in the coming years. This has led to over 300 drainage improvement projects in various parts of Singapore.

Innovations in flood protection

The Dam Easy Flood Panel (DFP) and Portable Flood Barriers (PFB) are two projects currently being tested by PUB to better protect the public from flash floods.

The DFP is a device that’s installed across doorways to prevent floodwaters from entering buildings, while the PFB is deployed on roads and pavements to divert floodwaters away from traffic.

Boosting scientific knowledge

Since 2013, Singapore has pioneered research into tropical climate and weather in Southeast Asia, with the Centre for Climate Research Singapore (CCRS). A further $10 million has been channelled into research on rising sea levels.

Game Changers—Stopping a sea change

Singapore is not only concerned about too much water (rain), but also other extreme weather conditions which result from climate change, like dry spells and bush fires.

Did you know that saving water can help in our fight against climate change? It reduces our electricity consumption for water treatment and production, and in myriad other ways.  Here are some thematic tips that’ll save the environment and supercharge your climate change game.

1. Tap on, tap off

Turning off the tap or showerhead while brushing your teeth or soaping your hair may sound insignificant, but small habits like these certainly add up in the long run.

2. Avoid bottled water and disposable containers

8 million tons of plastic enters our oceans every year. If possible, try to bring a reusable bottle around instead of buying bottled water or drinks. Tap water in Singapore is perfectly safe and clean for drinking so just refill your bottle at any water point. You may also want to skip that plastic straw, and swig your drink like a champ!

3. Get water-saving products

A quick online search will help you find a range of household brands and products (showerheads, washing machines, dishwashers etc) that will help you save on your water bill.

4. Consider drinking more tea

Fun fact: From growing a bean to being poured into your mug, a cup of joe takes 140 litres to create, while a cup of tea takes only 34 litres.

Saving Semakau — One island’s role in managing Singapore’s waste

Can all of Singapore’s trash fit on one little island? The answer’s yes, but not for long!

The Little Landfill That Could

Think of Singapore’s outlying islands, and you’ll probably imagine petting the tortoises on Kusu island, diving at Pulau Hantu, or camping on Saint John’s Island. But have you heard of Pulau Semakau?

Located eight kilometres off Singapore’s Southern Coast, this little island is home to Singapore’s only landfill—a 3.5 square-kilometre space that holds all the trash of Singapore’s 5.6 million people.

That’s no mean feat, considering that as a nation we generated 7.7. million tonnes of waste in 2018. Imagine just a fraction of that weight filling the Semakau Landfill each year, and you can probably imagine why our waste problem is piling up.

So, how does one little island hold all that trash? We delve into what makes this ingenious landfill tick, and clear up some misconceptions you might have about Pulau Semakau.

Going Green — Transforming Transport

From cleaner vehicles on the road to an expanded rail network, Singapore is firmly on track to a more sustainable transport system.

Often lauded for its affordable, efficient and highly-interconnected public transport network, Singapore is certainly well-equipped to combat carbon emissions when it comes to greener forms of commuting.

The compact, interconnected nature of our city is a boon in the fight against climate change, as it makes public modes of transport not only possible, but highly convenient.

By 2040, we hope to have 9 in 10 peak-period journeys made through walking, cycling or riding public and shared transport.

Commuters should be able to complete their journeys in 45 minutes during peak periods, while amenities within the neighbourhood should be no more than 20 minutes away.

While this sounds like an ambitious goal, changes are already underway to turn this into a reality. Here are some plans that are being put into place:

How to be a climate change gamechanger

Everyone can make a difference to fight climate change! Here are 3 simple ways you can reduce your energy usage and carbon emissions.

#1 – Increase your air-conditioner temperature by 1oC

Less energy is used by your air-conditioner when you increase the temperature setting. For every degree raised, you can save an additional $15 a year!
