Building a Sustainable Future

As a small island nation with limited natural resources, Singapore faces unique challenges in its journey toward sustainability. Yet, the city-state has demonstrated remarkable commitment to building a greener future through ambitious policies, innovative technologies, and collaborative efforts. In this article, we explore how Singapore is leveraging green energy solutions to create a more sustainable future for its citizens and the planet.

Singapore's Green Plan 2030

In February 2021, Singapore unveiled the Singapore Green Plan 2030, a national sustainability movement that charts ambitious and concrete targets over the next ten years. This whole-of-nation effort seeks to advance Singapore's national agenda on sustainable development and position the country to achieve its long-term net-zero emissions goal.

The Green Plan encompasses five key pillars:

1. City in Nature

Creating a green, livable, and sustainable home for Singaporeans by expanding nature parks, planting one million more trees, and developing new parks and park connectors.

2. Energy Reset

Transforming how and what Singapore consumes by increasing solar energy deployment to at least 2 GWp by 2030, greening 80% of buildings by 2030, and promoting energy-efficient practices.

3. Sustainable Living

Encouraging reduction in waste, consumption, and carbon footprint through initiatives like the "Reduce, Reuse, Recycle" campaign, encouraging electric vehicle adoption, and promoting sustainable consumption habits.

4. Green Economy

Seeking innovative sustainability solutions for business and creating job opportunities in sectors like clean energy, circular economy, and carbon services.

5. Resilient Future

Building capabilities to adapt to climate risks and protect our coastlines and biodiversity through infrastructure enhancements and nature-based solutions.

Green Energy Initiatives Driving Sustainability

Within the broader framework of the Green Plan, several green energy initiatives are playing crucial roles in advancing Singapore's sustainability agenda:

1. Solar Energy Expansion

As Singapore's most viable renewable energy source, solar power is being aggressively expanded across the island. Beyond rooftop installations, innovative approaches like floating solar farms, building-integrated photovoltaics, and vertical solar panels are being explored to maximize solar deployment in land-scarce Singapore.

The SolarNova program, led by the Housing & Development Board (HDB) and the Economic Development Board (EDB), has been instrumental in accelerating solar adoption across public housing estates and government buildings.

2. Energy Storage Systems

To address the intermittent nature of solar energy, Singapore is investing in energy storage solutions. The Energy Market Authority (EMA) has deployed a 2 MW/2 MWh battery energy storage system at a substation in north Singapore as a testbed. Such systems are critical for grid stability as renewable energy penetration increases.

3. Smart Grid Technologies

Singapore is developing smart grid capabilities to enhance the efficiency and reliability of its power system. These include advanced metering infrastructure, demand response programs, and grid monitoring systems that enable better integration of distributed energy resources.

4. Green Hydrogen

Recognizing the limitations of solar energy alone, Singapore is exploring hydrogen as a complementary clean energy source. The government has initiated research into hydrogen technologies and is considering hydrogen imports from countries with better renewable energy resources.

5. Low-Carbon District Cooling

District cooling systems, which centralize the production of chilled water for air conditioning multiple buildings, can reduce energy consumption by up to 40% compared to conventional air-conditioning systems. Singapore has implemented such systems in the Marina Bay and Punggol Digital District and plans to expand to more areas.

The Role of Businesses in Singapore's Sustainability Journey

While government initiatives provide the framework, businesses play a crucial role in driving the transition to a more sustainable Singapore. Companies across various sectors are adopting green practices, investing in renewable energy, and developing innovative solutions to address environmental challenges.

Corporate Renewable Energy Adoption

More and more businesses in Singapore are turning to renewable energy to power their operations. Options include:

• Solar Leasing: Companies can lease their rooftop space to solar developers who install, own, and maintain the solar system, selling the generated electricity back to the company at competitive rates.
• Power Purchase Agreements (PPAs): Long-term contracts to purchase renewable energy from developers, providing businesses with clean energy and price stability.
• Renewable Energy Certificates (RECs): Financial instruments that represent the environmental attributes of renewable energy, allowing companies to claim the green benefits even if they cannot install renewable energy systems on-site.

Green Building Transformation

The building sector accounts for over 20% of Singapore's carbon emissions. Businesses are increasingly adopting green building practices to reduce their environmental footprint:

• Energy-Efficient Retrofits: Upgrading existing buildings with energy-efficient lighting, HVAC systems, and building management systems.
• Green Building Certification: Pursuing certifications like Green Mark to demonstrate commitment to sustainability and enhance property value.
• On-Site Renewable Energy: Installing solar panels or other renewable energy systems to reduce reliance on grid electricity.

Sustainable Supply Chains

Forward-thinking businesses are extending their sustainability efforts beyond their operations to their supply chains:

• Supplier Engagement: Working with suppliers to reduce emissions and improve environmental performance.
• Circular Economy Practices: Redesigning products and processes to minimize waste and maximize resource reuse.
• Carbon Footprint Measurement: Quantifying emissions across the value chain to identify reduction opportunities.

Challenges and Opportunities on the Path to Sustainability

Despite significant progress, Singapore faces several challenges in its sustainability journey:

1. Space Constraints

Singapore's limited land area restricts the deployment of land-intensive renewable energy technologies. Continued innovation in space-efficient solutions is needed.

2. Intermittency of Renewable Energy

The variable nature of solar and wind power requires robust energy storage and grid management solutions to ensure reliable power supply.

3. Economic Considerations

While renewable energy costs have declined significantly, the transition to green energy requires substantial upfront investment.

However, these challenges also present opportunities for innovation, collaboration, and leadership. Singapore's commitment to research and development, coupled with its strategic location and strong governance, positions it well to become a hub for sustainable solutions that can be exported to the region and beyond.

Looking Ahead: Beyond 2030

While the Green Plan 2030 provides a roadmap for the next decade, Singapore's sustainability journey extends far beyond. The country has committed to achieving net-zero emissions "as soon as viable" in the second half of the century.

Emerging technologies such as advanced battery storage, green hydrogen, carbon capture and utilization, and next-generation solar cells will likely play increasing roles in Singapore's energy landscape. International collaboration, particularly through regional power grids and clean energy imports, will also be critical in overcoming the inherent limitations of Singapore's resource constraints.

By embracing innovation, fostering collaboration, and maintaining its steadfast commitment to sustainability, Singapore is well-positioned to build a greener, more resilient future for its citizens while contributing to global efforts to address climate change.
