To attain this vision of net zero emissions by 2050, Singapore is breaking new ground with innovative
solutions to address its unique challenges. One groundbreaking initiative involves the possibility of
importing renewable energy from distant nations through undersea cables, a concept that could reshape
the global energy landscape. The country’s limited land availability has prompted this bold idea as it
seeks to transition to carbon-free energy sources and capture residual emissions. Pioneering
technologies, such as district cooling, are playing a crucial role in Singapore’s green journey.
By centralizing cooling systems, SP Group efficiently cools numerous skyscrapers and developments in
the Marina Bay area, saving valuable space that would otherwise be occupied by air conditioning
equipment. Additionally, the system acts as an “ice battery,” storing freezing water during off-peak hours
and supplying the cooling network during peak times, resulting in impressive energy efficiency gains.
The country is also looking at offshore solar installations, where solar panels placed atop water bodies
increase energy production and reduce land use.
EDP Renewables APAC’s floating solar farm in Johor Strait demonstrates the viability of this approach,
utilizing plastic pontoons to keep the panels afloat. While challenges remain, Singapore’s pioneering
efforts show promise for transforming solar energy deployment. Water scarcity is another pressing
concern for Singapore, which once heavily relied on Malaysia for water supply. The country has since
reduced this dependency through rainwater collection, wastewater recycling, and seawater desalination.
PUB, Singapore’s water management agency, is dedicated to improving the energy efficiency of
desalination, aiming to halve its energy use by 2025.
