Renewable energy opportunities for businesses in Southeast Asia are more critical than ever.Southeast Asia’s energy demand is expected to double by 2040, yet over 80% of this still comes from fossil fuels. In a region rich with solar, wind, and geothermal potential, the transition to renewables is becoming urgent.
Rapid industrialization, rising urban populations, and increasing energy demand are pushing governments and businesses to rethink their energy strategies. While fossil fuels have historically dominated the region’s energy mix, the growing urgency of the climate crisis, combined with global ESG pressures, is accelerating the shift toward renewable energy.
The potential is massive: abundant sunshine, geothermal activity, vast coastlines for wind energy, and rich rivers for hydropower. For businesses in the region, this presents both a responsibility and an opportunity to lead the green transition.
Untapped Renewable Energy Potential
Southeast Asia boasts diverse renewable resources:
- Solar and Wind: Vietnam has surged ahead with solar installations, while Thailand and the Philippines are making progress in wind energy. The cost of these technologies is declining, making them competitive alternatives.
- Geothermal and Hydropower: Indonesia and the Philippines are rich in geothermal energy, while countries like Laos already derive a significant portion of their power from hydropower.
- Regional Power Integration: The ASEAN Power Grid initiative is designed to promote energy security and sustainability by interconnecting national power grids, allowing clean energy to flow across borders.

Barriers to Renewable Energy Adoption ASEAN
Despite the potential, several roadblocks hinder progress:
- Regulatory and Policy Gaps: Inconsistent policies and a lack of transparency can deter investment. Without clear, supportive frameworks, private sector participation remains limited.
- Financing Challenges: Renewable projects require significant upfront capital. According to the International Energy Agency (IEA), Southeast Asia must increase clean energy investments to $190 billion annually by 2035 (nearly five times the current level) in order to meet its climate goals.
- Grid and Infrastructure Limitations: Many countries face aging grids that are ill-equipped to handle intermittent renewable energy sources.
- Community Concerns and Land Use: Local opposition and environmental concerns around land use and biodiversity can delay or derail projects.
Breakthroughs and Success Stories
Amid the challenges, several bright spots offer hope and guidance:
- Vietnam’s Solar Boom
In just a few years, Vietnam has installed more than 18 GW of solar capacity, thanks to favorable feed-in tariffs and government support.
- Malaysia’s Green Momentum
With new cross-border energy trading platforms like Enegem and a 70% renewable target by 2050, Malaysia is positioning itself as a regional clean energy hub.
- Public-Private Collaborations
International firms like ACWA Power are investing in large-scale renewable infrastructure, signaling confidence in the region’s direction.
These success stories illustrate that with the right policy mix and incentives, Southeast Asia can scale its renewable ambitions. As these examples show, the momentum is building. So what does this mean for businesses in the region?
Opportunities for Businesses
For businesses across Southeast Asia, the shift to renewables is not just an environmental mandate, it’s a strategic advantage:
- Green Investments: Governments are offering incentives and subsidies for clean energy projects. Early movers can benefit from cost savings and market leadership.
- Innovation and Tech Adoption: Technologies such as floating solar farms, microgrids, and battery storage open new frontiers for renewable deployment.
- Stronger ESG Positioning: Integrating sustainability into core strategy helps attract investors, meet global compliance, and build brand trust.
- Local Supply Chain Development: Developing local expertise and equipment supply chains reduces import dependency and builds resilience.
How Southeast Asian Businesses Can Get Started with Renewable Energy
1.Conduct an Energy Audit
Identify where energy is used most and assess the feasibility of clean alternatives like solar, wind, or biomass.
2.Collaborate with Clean Tech Partners
Partner with energy service companies (ESCOs), renewable energy developers, and technology providers for expertise and innovation.
3.Integrate ESG Goals into Core Strategy
Align energy decisions with ESG reporting standards to attract investors and enhance brand reputation.
