Renewable Energy Investment Opportunities in 2026

Renewable energy investment opportunities are moving beyond their early growth stage and into what analysts increasingly describe as a structural phase, one defined by scale, economics and sustained capital flows rather than policy alone.

Solar power, wind and hydropower are now firmly embedded in national energy strategies, corporate decarbonisation plans and grid expansion programs across major economies.

That shift is evident in the data. Renewables have become the world’s largest source of electricity generation, overtaking coal for the first time. And capital is following suit.

In 2025, global investment in clean energy — including renewables, energy storage and grid optimisation — reached nearly USD 2.2 trillion, roughly double the amount directed toward fossil fuels, coal, oil and natural gas, and up from USD 2 trillion the previous year.

Renewable energy investment alone is projected to hit USD 780 billion, outpacing oil investment by an estimated USD 245 billion.

Solar Leads the Energy Transition as Capital Scales Up

Solar continues to dominate. Investment in utility-scale and rooftop solar is expected to reach USD 450 billion in 2025, while global spending on battery storage for the power sector is forecast to hit USD 66 billion.

The drivers extend beyond climate targets and technological advances. In many markets, renewable power is now simply cheaper to build and operate than coal or gas.

“Renewables remain the lowest-cost source of new electricity and the fastest to deploy and scale,” says Connor Teskey, CEO of Brookfield Renewable Partners. “Solar and wind projects anchor new-build pipelines, supported by long-term, inflation-linked corporate and utility offtake agreements.”

For investors, that cost advantage — combined with long-term contracts — helps dispel the notion that renewables are merely a policy-dependent trend.

Is Renewable Energy a Good Investment?

The short answer is yes — but with greater selectivity than during the boom years of the early 2020s. Plunging technology costs, particularly in solar and wind, have made renewables a compelling institutional asset class. Improvements in efficiency of solar panels, wind turbine design and project execution have translated into stronger and more predictable returns.

According to enterprise decarbonisation platform Tellus Markets, equity and debt markets are becoming progressively more favourable to renewable developers. “Large-scale solar and wind developers have paid back investors with relatively few casualties — certainly by comparison with oil and gas,” the firm notes.

Regulatory reforms are further expanding investment opportunities in the renewable energy industry.. Several countries now allow 100% foreign ownership in renewable energy projects. The Philippines, for example, fully opened its solar, wind, biomass and tidal sectors in 2022, while India has permitted full foreign direct investment through the automatic route since 2023. Oman and other emerging markets are also attracting capital with liberalised policies, reflecting a broader push to draw global investment into the energy transition.

Energy Investment Becomes More Selective

According to EU Solar, renewable energy investments delivered average annual returns of 15.7% over the past decade, significantly outperforming traditional energy investments.

Yet, capital allocation is becoming increasingly disciplined. Heading into 2026, investors are prioritising projects with clear revenue visibility, proven technologies and strong balance sheets, rather than speculative growth.

“Corporates are becoming more selective about their projects,” says David Wadham, energy partner at law firm Ashurst. “People still want to invest in the transition, but there’s a greater focus on the economics of each project, based on use cases and available subsidies.”

Utility-scale Clean Energy Projects Anchor Institutional Capital

Large-scale solar and wind developers remain among the most stable entry points into renewable investing. These companies benefit from long-term power purchase agreements (PPAs), predictable cash flows and deep project pipelines.

NextEra Energy, one of the world’s largest renewable power producers, continues to be widely viewed as a bellwether for the renewable energy sector. Its aggressive expansion across North America and strong balance sheet illustrate how renewables have matured into an institutional-grade investment.

Outside the US, companies such as Portugal’s EDP Renováveis and India’s Adani Green Energy are scaling rapidly across Europe, South Asia and emerging markets. Their growth reflects a broader trend: renewable capacity additions are increasingly concentrated in regions with fast-growing electricity demand and supportive policy frameworks.

Onshore Wind Energy Projects Gain Ground

While wind power remains a central pillar of renewable growth, momentum within the sector is diverging.

Offshore wind is losing traction as rising costs, supply-chain constraints, lengthy permitting processes and volatile power prices undermine project economics. Investors are increasingly shifting their focus onshore, prompting a 26% reduction — equivalent to 26 GW — in offshore capacity projections for 2025–2030, according to the International Energy Agency.

Yet, the broader wind sector remains on a strong growth trajectory. Global wind capacity is still set to almost double, surpassing 2,000 GW by 2030. Offshore wind is projected to add 140 GW over the forecast period — more than twice the growth of the previous five years — driven largely by China.

Onshore wind, however, continues to lead. Cumulative additions are expected to rise 45% to 732 GW between 2025 and 2030, supported by improving policy frameworks and expanding markets across Europe, India and emerging regions.

Energy Storage Rises to Meet Increasing Demand for Grid Stability

As renewable penetration deepens, energy storage has become indispensable for grid stability. Investment in energy storage is expected to accelerate through 2026, driven by grid modernisation, data centre expansion and the electrification of transport.

According to the IEA, global investment in battery energy storage systems (BESS) has climbed from roughly USD 1 billion in 2015 to an estimated USD 66 billion in 2025 — approaching investment levels in gas-fired power generation.

That growth is drawing institutional capital at scale. Global real estate services firm JLL notes rising investor interest in BESS, reflected in moves by players such as Generali’s Sosteneo Energy Transition Fund, which last year acquired two UK battery storage assets from renewables developer Pacific Green.

Energy storage is also a core pillar for pension-backed platforms including Renewable Power Capital, established by Canada’s CPP Investments, while private equity firms are stepping up: KKR invested USD 750 million in UK-based battery developer Zenobē in 2024.

“More investors are showing increased appetite for utility scale BESS,” says Max Stirling, director of energy and infrastructure advisory for EMEA at JLL. “They appreciate the fact that it’s a growth market and a long-term revenue play with potential for double-digit rates of return.” Paul Betts, managing director of M&A Europe at RBC Capital Markets, echoes that view, pointing to batteries as “one of the biggest verticals” for capital deployment.

Improving economics are reinforcing the case. Utility-scale battery costs are approaching USD 80 per kilowatt-hour — around half their 2023 levels — cutting payback periods to between four and 10 years, depending on location and use case.

Asia: The Epicentre of Renewable Energy Investment Opportunities in 2026

Asia is set to dominate renewable energy investment in 2026, accounting for the largest share of new global capacity. Rapid urbanisation, rising electricity demand and government-led decarbonisation efforts are driving unprecedented deployment.

China remains the world’s biggest renewable market, leading in solar manufacturing, wind installations and battery storage. In 2024, its clean energy investment exceeded USD 625 billion, nearly doubling since 2015. The country also met its 2030 wind and solar targets six years ahead of schedule.

India is emerging as another key destination, buoyed by ambitious capacity targets, strong policy support and growing corporate demand for clean power.

Private Capital Fuels Renewable Growth in Southeast Asia

Meanwhile, Southeast Asia is gaining momentum as countries including Vietnam, Indonesia and the Philippines expand solar, wind and grid infrastructure — often with support from multilateral lenders and private capital.

“Across Southeast Asia and Africa, private capital is increasingly flowing into distributed solar, mini-grid and storage projects as governments prioritize energy access and reliability,” says Rob Day, a US-based sustainable resources private-equity investor.

Clean Energy Landscape: From Growth to Maturity

By 2026, renewable energy is unlikely to be defined by speculative growth. Instead, it is entering a more mature phase marked by infrastructure build-out, grid integration and steady capital deployment.

The strongest opportunities are likely to emerge from a balanced mix of utility-scale generation, enabling technologies such as storage, and selective exposure to emerging markets.

Risks remain. Policy shifts, grid bottlenecks, permitting delays and commodity price volatility can all affect returns. But for investors willing to look beyond short-term fluctuations, renewable energy remains one of the most structurally supported investment themes of the decade.
