The Environmental Impact of Going Solar

Your Carbon Footprint Matters

Singapore's electricity generation still relies heavily on natural gas. By going solar, you're directly reducing carbon emissions and supporting the nation's sustainability goals.

Environmental Benefits by Numbers

A typical 5kW residential solar system in Singapore prevents approximately 2.5 tonnes of CO2 emissions annually. Over 25 years, that's equivalent to:

• Planting 1,200 trees
• Removing a car from the road for 1.5 years
• Saving 6,250 kg of coal from being burned

Singapore's Solar Target

Singapore aims to deploy at least 2 gigawatt-peak of solar capacity by 2030. Residential and commercial installations are crucial to achieving this goal and reducing the nation's carbon intensity.

Beyond Carbon Reduction

Solar energy also reduces:

• Air pollution from power generation
• Water usage (solar uses virtually no water vs. thermal power plants)
• Land use conflicts (rooftop solar doesn't require additional land)

Singapore's National Sustainability Targets

Singapore has committed to achieving net-zero emissions by 2050 as part of the Singapore Green Plan 2030. Solar energy plays a central role in this strategy, with the government targeting at least 2 gigawatt-peak (GWp) of solar capacity by 2030 — enough to power approximately 350,000 households annually.

Breaking Down Your Personal Impact

A typical 5kW residential system in Singapore prevents 2.5 tonnes of CO2 annually. To put this in local context:

• Singapore's per capita carbon footprint is approximately 8 tonnes CO2/year
• One solar installation offsets roughly 31% of an average Singaporean's emissions
• Over 25 years, this equals 62.5 tonnes — equivalent to taking a car off Singapore roads for 12 years

For a landed property with a 10kW system, annual CO2 reduction reaches 5 tonnes — comparable to the carbon sequestered by 200 mature trees in the Singapore Botanic Gardens.

Comparing Solar to Other Green Actions

While every action counts, solar delivers outsized environmental returns compared to common lifestyle changes:

Local Environmental Benefits

Singapore's dense urban environment means rooftop solar delivers additional benefits beyond carbon reduction:

• Reduced urban heat island effect: Solar panels absorb sunlight that would otherwise heat rooftops, potentially reducing building cooling loads by 5-10%
• Improved air quality: Every kWh of solar offsets natural gas power generation, reducing local NOx and particulate emissions
• Water conservation: Solar PV uses virtually no water, unlike thermal power plants. A 5kW system saves approximately 4,000 liters of water annually compared to fossil fuel generation

Supporting Singapore's Energy Security

Singapore imports over 95% of its energy. Distributed rooftop solar enhances energy security by reducing reliance on imported natural gas. The EMA's distributed solar strategy emphasizes rooftop installations precisely because they provide resilient, localized energy generation without requiring additional land — a scarce resource in Singapore.

Singapore's Emissions Challenge

As a low-lying island nation, Singapore is particularly vulnerable to climate change impacts including rising sea levels and extreme weather. The city-state has committed to achieving net-zero emissions by 2050, with the energy sector being a primary focus. Currently, natural gas generates over 95% of Singapore's electricity, making the transition to renewables critical.

Carbon Intensity of Solar

The carbon footprint of solar panel manufacturing is typically offset within 1-3 years of operation. Over a 25-year lifespan, a residential solar system prevents 30-50 tonnes of CO2 emissions — equivalent to planting 1,500 trees or removing a car from the road for 10 years. Given Singapore's carbon intensity of 0.43 kg CO2/kWh, every kWh of solar energy makes a meaningful difference.

SolarNova's National Impact

The government's SolarNova programme targets 2 GWp of solar capacity by 2030. If achieved, this would generate approximately 2.6 TWh annually — about 4% of Singapore's current electricity demand. While modest in isolation, this represents a significant step toward diversifying the energy mix and reducing dependence on imported natural gas.

Local Air Quality Benefits

Beyond carbon reduction, solar energy eliminates local air pollutants associated with fossil fuel combustion, including nitrogen oxides, sulfur dioxide, and particulate matter. In densely populated Singapore, improving air quality through distributed solar generation has direct public health benefits, reducing respiratory illnesses and healthcare costs.
