Quick Takeaways

  • India committed in 2014 to installing 100 gigawatts of solar by 2022, starting from just 3 gigawatts and effectively needing to double capacity every 18 months.
  • By February 2025, India reached the 100-gigawatt solar milestone, catalyzing $90 billion in investment and 300,000 new solar jobs.
  • India's solar bet was driven primarily by economic reasons, recognizing that renewables are good economics rather than purely an ideological climate choice.
  • High financing costs in developing countries can make up to 70% of the cost of a single unit of solar electricity, so financial and market innovation are crucial.
  • India addressed investor concerns by reforming how utilities contracted and paid for solar power, engaging state governments, large consumers like railways, and development partners.
  • Chawla distills the path from ambition to action into three levers: planning, innovation, and localization.
  • Ghana used detailed planning to move its net-zero target from 2070 to 2060 after assessing evidence and trade-offs.
  • Results-based financing mechanisms in sub-Saharan Africa have helped expand small-scale solar while managing quality and financial risks, enabling tens of thousands of new connections.
  • Kenya, already at 90% clean power, is pushing towards 100% by 2030 while shifting from importing solar panels to building local manufacturing zones to retain value and create jobs.
  • Chawla argues the global energy transition is already underway and irreversible, led by developing countries that choose renewables for growth, development, and prosperity.

Economic motivations and financing challenges for renewable energy

Motivation behind India's bet on solar

Non-ideological drivers[5:41]
• Chawla emphasizes that India did not bet on solar for ideological reasons.
• She argues India chose solar for economic reasons, recognizing early that transitioning to renewable energy is good economics.

Chawla's broader experience and central question

Work with multiple countries over 15 years[5:59]
• Chawla notes she has worked with a range of countries over the last 15 years.
Key question about paying for commitments[6:03]
• She highlights a recurring question: commitments are good, but how are they going to be paid for?
High cost of finance in developing countries[6:15]
• Chawla points out that in many developing countries the cost of finance remains high.
• She notes that as much as 70% of the cost of a single solar electron could come from the cost of capital.

Role of innovation beyond technology

Technological cost reductions in solar[6:20]
• She credits technology innovation with rapidly bringing down the price of solar energy.
• According to Chawla, solar has become the cheapest source of electricity in every single market in the world.
Limitations of technology innovation alone[6:39]
• She stresses that technology innovation alone is not enough to get the energy transition done.
• India's solar story is described as being equally about business models and market design, not just technology.

India's solar market design: challenges and responses

Initial private sector response and capital constraints

Private sector eagerness[6:55]
• When India first made its solar commitment, the private sector responded eagerly.
• Developers and manufacturers came readily to what Chawla calls India's solar party.
Elusiveness of capital[7:02]
• Despite developer interest, capital remained elusive.

Structural issues in electricity utilities

Dependence on utilities as off-takers[7:09]
• Chawla explains that much of the new solar power would have to be purchased by India's electricity utilities.
Poor financial health of utilities[7:14]
• These utilities had been chronically in very bad financial health.
Risk of adding variable solar to utility portfolios[7:19]
• Adding large shares of variable solar-which at the time was still somewhat more expensive-was not going to make utilities' lives easier.
Delayed payments and investor concerns[7:26]
• Utilities delayed payments to solar developers, putting many out of business.
• These delays spooked investors, undermining confidence.
• Chawla says this was not a good look for a country trying to raise $100 billion of solar investment.

Government experimentation to unlock capital

Engaging state governments to generate demand[7:43]
• The government worked with state governments to get them to demand solar power from their electricity utilities.
Using large consumers as anchor customers[7:54]
• It also worked with other large consumers, such as the railways, to have them act as anchor customers for new solar parks.
Fortifying energy infrastructure with development partners[8:03]
• The government collaborated with development partners to fortify energy infrastructure.
• This infrastructure strengthening was intended to allow more solar energy to be integrated into the grid.
Improvement in payment discipline and investor confidence[7:26]
• These measures did not solve all of the utilities' financial problems.
• However, they ensured that utilities paid their solar bills on time.
• Chawla notes that timely payment was enough to attract capital back to India's solar sector.

Emphasis on "boring" but crucial tools

Revolution built on mundane mechanisms[8:26]
• Chawla remarks that the exciting revolution was built on the back of quite boring things.
• She lists these as plans, policies, and business models.

Three levers from ambition to action: planning, innovation, localization

General framework of three levers

Global evidence from multiple countries[8:40]
• Chawla says that examples from around the world of similar tools unlocking solar gains shaped her thinking.
Distillation into three levers[8:53]
• She believes the road from ambition to action can be distilled into three distinct levers.
• She names these levers as planning, innovation, and localization.

Lever 1: Planning

Role of plans in making commitments real[9:01]
• Chawla says plans are what make commitments real.
Example: Ghana's net-zero pathway[9:10]
• She cites work that her organization, Sustainable Energy for All, has done with the government of Ghana.
• Ghana already had a commitment to reach net zero by 2070.
• In the process of making a detailed plan, Ghana examined evidence and trade-offs.
• This planning allowed Ghana not just to create a how-to guide, but also to shift its target to achieve net zero by 2060 instead of 2070.

Lever 2: Innovation

Need to put plans into motion[9:33]
• Chawla notes that plans must be put into motion, and this is where innovation plays a role.
Developing countries as innovation hotbeds[9:40]
• She describes developing countries as hotbeds for innovation.
Example: Results-based financing for small solar in sub-Saharan Africa[9:54]
• Chawla discusses sub-Saharan Africa, where scaling small solar solutions is limited by both financial viability and quality concerns.
• She explains an innovative results-based financing mechanism that splits payments partly at the start and partly at the end of a project after quality checks.
• This structure addresses both financial and quality risks.
• One such facility leveraged $13.5 million to unlock 55,000 new connections across five countries.

Lever 3: Localization

Energy transition as value and prosperity creation[10:20]
• Chawla frames the energy transition as a story about creating value and prosperity.
Importance of localization[10:21]
• She argues that localization becomes really important in capturing this value.
Example: Kenya's clean power mix and manufacturing strategy[10:25]
• Chawla highlights Kenya, describing it as a renewable energy powerhouse.
• She says 90% of Kenya's power already comes from clean energy sources.
• This puts Kenya well on its way to its goal of 100% clean power by 2030.
• In pursuing this goal, Kenya imported $50 million worth of solar panels in a single year.
• Chawla points out that this is money sent out of the country.
• She notes that the government is now "having none of it" and is developing special manufacturing zones.
• These zones aim to keep this money in the country and create jobs for local Kenyans.

Developing countries as drivers of an irreversible energy transition

Evidence that the energy transition is underway

Non-isolated nature of examples[11:04]
• Chawla stresses that the cases she mentioned are not isolated examples.
Irreversibility and leadership by developing countries[11:22]
• She says these cases are evidence that the energy transition is already underway.
• She asserts that the energy transition is irreversible and is being driven by developing countries.

Global demographics and energy demand

Share of world population in developing countries[11:31]
• Chawla states that 84% of the world's population lives in a developing country.
• She rephrases this as four out of every five people in the world living in a developing country.
Need for more energy in developing countries[11:22]
• She describes these as countries in motion that need more energy to meet unmet demand.
• They need energy to power their economies and create jobs for their youth.

Decisive role of fuel choices and renewables economics

Impact of choices on future emissions[11:50]
• Chawla notes that the fuels these countries choose to meet energy demand will determine what future emissions look like.
Preference for renewables based on economics[12:00]
• She says these countries are already choosing renewable energy.
• They are doing so because renewables are good economics and offer opportunities for growth, development, and prosperity.

Call to action for global support

Need to enable developing countries at scale[12:10]
• Chawla argues it is now up to everyone to enable these countries at scale.
Emphasis on planning, market design, and capacity building[12:16]
• She calls for using the seemingly boring tools of planning, market design, and capacity building to sustain momentum.
Urgency and closing statement[12:14]
• Chawla concludes that the time is right and "we can't stop now," followed by thanking the audience.

Lessons Learned

Actionable insights and wisdom you can apply to your business, career, and personal life.

1

Aligning climate action with economic self-interest makes ambitious transitions politically and financially viable, as seen in India's choice to pursue solar for economic rather than ideological reasons.

Reflection Questions:

  • • Where in your work or community could you reframe an environmental or social initiative in terms of clear economic benefits?
  • • How might emphasizing cost savings, risk reduction, or new revenue streams change stakeholders' willingness to support a sustainability project you care about?
  • • What is one current initiative you could repackage this month to better highlight its economic upside for decision-makers?
2

Robust, evidence-based planning turns distant commitments into actionable roadmaps and can even reveal that more ambitious timelines are possible, as demonstrated by Ghana moving its net-zero target from 2070 to 2060.

Reflection Questions:

  • • What major goal in your life or organization currently lacks a concrete, step-by-step plan?
  • • How could gathering better data and explicitly mapping trade-offs help you either accelerate or de-risk that goal?
  • • What is one planning exercise you could schedule in the next two weeks to stress-test and refine a long-term commitment you've made?
3

Financial and business-model innovation are just as critical as technological innovation when scaling new solutions, especially in contexts where the cost of capital is high.

Reflection Questions:

  • • In a current project, are you focusing mostly on the technical solution while neglecting the financing or business model that would make it scalable?
  • • How could you redesign incentives, payment structures, or risk-sharing so that more partners are willing to participate?
  • • What small experiment could you run this quarter to test a new pricing, financing, or partnership model for your idea?
4

Localization-capturing more of the value chain domestically or within your own ecosystem-can turn external spending into local jobs, skills, and long-term resilience.

Reflection Questions:

  • • Where are you or your organization currently sending significant value outside (through imports, contractors, or external platforms) that could potentially be localized?
  • • How might building local capabilities or partnerships change your costs, control, and impact over the next five years?
  • • What is one part of your value chain you could begin to localize or internalize in a pilot way over the next six months?
5

Seemingly "boring" tools-planning, market design, and capacity building-often drive the most durable change, even behind glamorous success stories.

Reflection Questions:

  • • Which foundational processes (planning, training, incentives, governance) are currently underinvested in your team or project?
  • • How could improving one of these unglamorous foundations unlock better performance or reduce recurring crises?
  • • What is one concrete, behind-the-scenes improvement you will commit to implementing in the next 30 days to strengthen your system?
