Renewable energy projects in India helped the country avoid $18 billion in fossil fuel costs during 2025, according to the International Renewable Energy Agency (IRENA). While solar and wind energy are increasingly cost-competitive, investors should monitor sector risks including rising manufacturing costs, high financing rates, and the impact of evolving trade policies on project execution.
What Happened
Renewable energy installations across India helped the country avoid an estimated $18 billion in fossil fuel expenditures during 2025, according to the latest report from the International Renewable Energy Agency (IRENA). Globally, the shift to renewables saved $480 billion in fossil fuel costs as over 90% of new utility-scale renewable projects generated power at a lower cost than the cheapest fossil fuel alternatives. For India, this underscores the increasing economic advantage of solar and wind power over traditional coal and gas-based generation.
Why Energy Savings Matter For India
India relies heavily on energy imports to meet its power demand. By generating more electricity from wind and solar, the country reduces its dependence on imported coal and gas, which are subject to global price volatility. This transition not only improves energy security but also shields the economy and consumers from the sudden price shocks often seen in global fuel markets. The cost-efficiency of renewables has now reached a point where, in many regions, adding new renewable capacity is cheaper than continuing to run existing fossil-fuel-based power plants, making the transition an economic imperative rather than just an environmental goal.
The Emerging Cost And Execution Risks
Despite the clear cost benefits of renewable energy, the sector faces new challenges that could impact project profitability. Globally, investment in clean technology manufacturing has fallen significantly, dropping from a quarterly peak of $70 billion in 2023 to about $35 billion by the end of 2025. For India, this is a critical monitorable. As global commodity prices rise and trade policies regarding import duties on solar modules and wind components evolve, the cost of installing new capacity may increase in 2026. Companies that rely heavily on imported components may face margin pressure if they cannot pass on these higher costs to customers or power distributors.
Financing And The Debt Question
Beyond the cost of technology, the cost of borrowing is a major hurdle. Many renewable energy projects are capital-intensive, meaning they require large loans upfront. IRENA notes that macroeconomic conditions, such as high interest rates, are now having a larger impact on project feasibility than the cost of the technology itself. For Indian power companies, high debt levels can limit the ability to expand capacity quickly. Investors should watch for companies that manage their balance sheets carefully and have access to affordable long-term financing, as these firms are better positioned to weather periods of high interest rates.
What Investors Should Track
As the renewable sector continues to grow, investors may want to monitor several key factors beyond just the headline capacity additions. First, track the commissioning timeline of major projects to ensure they are not facing delays due to supply chain or financing issues. Second, observe the profit margins of renewable companies, especially in a year where manufacturing and import costs may rise. Third, keep an eye on policy updates, such as changes in tariffs or domestic manufacturing incentives, which can directly affect project costs. Finally, companies with lower debt and strong cash flow will likely be more resilient to the challenges posed by high financing costs and market volatility.
