Roadmap for Extreme Heat Protection Through Passive Cooling in ASEAN Region

ASEAN region is experiencing unprecedented warming trends with increasingly severe extreme heat events which can reach 38 degree Celcius in major ASEAN cities by 2050. Everyone is at risk, but not equally. Vulnerable groups, including women, children, the elderly, and low income communities, are disproportionately affected with gender deepening existing inequalities. As extreme heat intensifies, rising demand for cooling drives up electricity use and greenhouse gas emissions and creating a vicious cycle. 

To address this, the ASEAN Centre for Energy (ACE) and the United Nations Environment Programme (UNEP) (through the Cool Coalition and EmPower: Women for Climate Resilient Societies Programme) have developed a roadmap to promote passive cooling strategies, presenting key recommendations that can be adopted by ASEAN Member States to scale up passive cooling solutions and foster more resilient cities in the region.

Powering Wellbeing: Rethinking Electricity Planning Beyond GDP in Southeast Asia?

This report examines the limitations of the GDP-centric development model that continues to guide electricity planning across Southeast Asia, with a focus on Indonesia, Viet Nam, Thailand and the Philippines. While these economies have expanded generation rapidly and achieved near-universal electricity access, the report finds that electricity planning remains largely oriented towards aggregate growth and industrial output. Using a Decent Living Standards framework, it estimates the minimum level of electricity required to secure basic well-being and shows that the central challenge is often not insufficient generation capacity, but the way electricity is allocated and priced. The report concludes with a policy toolkit to help reorient electricity governance from aggregate growth towards sufficiency.

Financing the ASEAN Power Grid

This report examines how interconnectors are approached today from the financing and business model perspective. It explores how, in combination with broad macro‑financial and market‑specific factors, current approaches may create challenges given the size and characteristics of the APG project pipeline. Rather than focussing on institutions or regulatory frameworks, this report approaches the issue through an investor’s lens – asking how these assets are financed in practice and what must change to make them bankable for a wide set of potential investors.

Energy Transition
Beyond Participation: Ellen Bomasang on Gender, Energy, and Structural Change

As the energy transition accelerates, questions of inclusion are moving from the margins to the center of the conversation. But while awareness of gender in energy has grown, progress in translating that awareness into action and structural change remains limited. In this conversation, Peter du Pont of SIPET Connect speaks with Ellen Bomasang, a long-time energy and development practitioner, about how her work in the energy sector has evolved, and what it will take to move from token inclusion to a transition that is just and equitable by design.

***

SIPET Connect: Let’s start with your journey: how did you get into the energy sector, and how has your work evolved since you started in the early 1990s?

Ellen: I’ve been working in energy since 1992, straight out of college. I started at the Philippine National Oil Company, first with its petroleum subsidiary, Petron, and then in geothermal. After that, I pursued graduate studies in Japan in public policy, focusing on energy. And then I worked at the Institute of Energy Economics, Japan.

That’s where I was first assigned to work on renewable energy. My first assignment was a a JICA-funded solar project in Zimbabwe. At the time, solar wasn’t considered mainstream at all; it was mostly seen as something for off-grid communities. Coming from work on oil and geothermal energy, that was a completely new perspective for me.

Over time, I’ve seen renewables evolve from something niche and expensive into a mainstream source of power. Along the way, my work has spanned policy, finance, project design, and community engagement, but what has really stayed with me is the focus on access and equity, especially in rural and underserved communities.

And I think that’s where gender naturally comes in. When you’re working on access and community-level energy systems, you start to see very clearly that women and men experience energy very differently, and that those differences are often not reflected in how programs are designed.

 

SIPET Connect: You’ve also moved across different roles, geographies, and sub-sectors. How did you navigate that without getting locked into one track?

Ellen: It wasn’t automatic, I had to be quite intentional about it. When I moved to the U.S., I was working with International Resources Group, but they weren’t doing much in off-grid renewables, which was what I was most interested in. So, I actively looked for opportunities and moved to Winrock International, where I stayed for about 14 years.

SIPET Connect: Yes, and that’s where you and I first met and worked together—on the USAID Eco-Asia Clean Development and Climate Program, back in 2006, where I was leading the regional effort and you were running teams in Indonesia and Vietnam.

Ellen:  That’s right, this was the first large regional USAID program covering all of Asia and focusing solely on clean energy. During my time at Winrock, I did a lot of work on household energy, electrification, and community engagement, and it’s also where I started working more directly at the intersection of gender and energy.

After a while, though, I started feeling a bit pigeonholed into Asia-focused work. I wanted to branch out, both geographically and in terms of the types of roles I was taking on. So, I moved on, which led to more senior roles and opportunities to work in sub-Saharan Africa, Latin America, and the Middle East.

For me, it was really about actively seeking out new spaces rather than waiting for them to come.

 

SIPET Connect: The idea of a “gender-just energy transition” has gained traction in recent years. How have you seen the conversation on gender in energy evolve over time?

Ellen: Earlier, the conversation was much more about inclusion in a general sense. This is what we often referred to as a “just transition”—meaning not leaving anyone behind.

What I’m seeing now is a more intentional recognition that women and other marginalized groups have different needs, different perspectives, and face different structural constraints. It’s not just about including them, but also about understanding those differences and designing systems accordingly.

In countries that are actively pursuing this, you see efforts to increase women’s participation in renewable energy jobs, to promote STEM education for girls, and to embed gender considerations into policy and resource allocation. There’s also more focus on access, making sure energy services are equitable and actually address the burden of energy poverty.

It’s becoming more deliberate, but there’s still a long way to go in terms of implementation.

 

SIPET Connect: Your doctoral research looks at women of color in international development. What led you to focus on that?

Ellen: It was really inspired by my own experiences, as well as those shared by colleagues. My research looks at how women of color experience power, oppression, and privilege within the sector.

I focused on energy, which is still very male-dominated, and the health sector, which is more diverse, to draw some comparisons. I conducted in-depth interviews with women of color and also spoke with practitioners from different backgrounds to get a fuller picture.

What comes through very clearly is that there are multiple layers of barriers, and they’re not always visible in the way organizations think about inclusion.

 

SIPET Connect: From your experience, what are the most persistent barriers that hold women back in the energy transition?

Ellen: There are quite a few, and they tend to reinforce each other.

Education and skills are a big one. Women are still underrepresented in technical fields, and that carries through into the workforce. Even in renewables, representation is only around 30 percent globally, and lower in the broader energy sector.

Then, there’s how the labor market is structured. Technical, field, and leadership roles are still dominated by men, and hiring often relies on networks that women don’t have the same access to.

There are also structural biases in policies and institutions. Even when things appear neutral, they often don’t account for realities like caregiving responsibilities, which affect women disproportionately.

Time poverty is another factor. Women are still managing multiple roles, childcare, household responsibilities, and in some contexts fuel and water collection, which limits their ability to participate in training, employment, or entrepreneurship.

And there are social norms. In many places, technical roles are still seen as men’s work. I’ve seen programs where only men were recruited for technical training, even though women might have been more likely to stay and apply those skills locally.

Finally, workplace environments can be a barrier, especially in male-dominated settings where there may be safety concerns, lack of mentorship, or limited support systems.

 

SIPET Connect: What have you seen actually work in moving beyond awareness to real change?

Ellen: One of the biggest lessons is that it’s not enough to simply increase participation. That was the approach for a long time, train more women, include more women. and then consider the job done.

What works better is addressing the underlying structural issues. That includes changing hiring practices, creating mentorship opportunities, and improving workplace culture so that women can actually thrive once they enter the sector.

Engaging men is also critical. In some of the programs I’ve worked on, bringing men into the conversation, helping them understand how certain behaviors or norms affect their colleagues, has made a real difference.

There’s also a strong case for starting early. We’ve done work with girls at the middle school level, introducing them to engineering and technical careers and connecting them with role models. That’s often the stage where career aspirations start to take shape.

And something that’s often overlooked is leadership training. Many programs focus on technical skills, but women also need support in navigating workplaces, negotiating, and advancing into leadership roles. In one program in Nigeria, we trained over a thousand women in leadership skills, and it was very well received and later replicated elsewhere.

I believe it’s really about addressing the full spectrum, from education to workplace dynamics to leadership.

 

SIPET Connect: Is there a risk that gender remains treated as a side issue rather than being fully integrated?

Ellen: Yes, and I’ve seen that happen. When gender is treated as a separate track or an add-on, it can actually create resistance.

I remember working on a project in Mongolia where we included a gender track in an energy conference. Some participants questioned why it was there at all, saying there were more “serious” issues to discuss.

That reflects a broader challenge. Gender is often labeled as cross-cutting, but it’s not given the same weight as technical components. And when budgets are tight, it’s often the first thing to be cut.

Where it works better is when leadership takes it seriously. If the project lead or the funder prioritizes it and integrates it into the core design of the program, then it becomes part of how the work is done, rather than something separate.

 

SIPET Connect: How do you see the role of gender lens investing and related approaches evolving?

Ellen: There’s definitely more interest, but adoption is still uneven.

In some of the work I’m doing now, we’re trying to integrate gender considerations into procurement processes, for example, assessing companies based on how inclusive their workplace policies are. But even then, there’s a question of how many companies will actually meet those criteria.

The evidence is quite clear that more inclusive workplaces lead to better outcomes, but that hasn’t fully translated into widespread practice yet.

 

SIPET Connect: Finally, what is one key takeaway you would leave for practitioners working on gender and energy?

Ellen: The main takeaway is that this is not just about participation.

If the focus is only on adding women, without addressing the underlying structural and systemic barriers, then the impact will be limited. What’s needed is a more transformative approach, looking at how systems are designed, whether that’s financing, labor markets, or energy access, and making sure those systems enable women to participate meaningfully and benefit equally.

A gender-just energy transition is really about ensuring that women are not only included, but that they have equitable access to opportunities and a role in shaping the transition itself.
