Three Sectors Ripe for Heavy Government Investment Ahead

The world economy is changing fast. Global growth is slowing, supply chains are shifting, and technology is moving at record speed. At the same time, climate change and health challenges are pushing governments to think beyond short-term fixes. According to the World Bank, targeted public investment can boost productivity and create lasting growth when private capital alone is not enough.

This is where smart government spending comes in. By directing funds to the right areas, we can build stronger economies, safer communities, and better futures. Not every sector deserves the same level of support. Some carry more weight for our collective progress. Three areas stand out today: renewable energy, digital infrastructure, and healthcare. Each has the power to create jobs, improve lives, and prepare us for the future.

We will explore why these sectors matter most and how heavy government investment can shape the path ahead.

Sector 1: Renewable Energy & Green Infrastructure

Clean power is moving from ambition to scale. In 2024, worldwide renewable capacity grew by 15.1%, with an additional 585 GW mainly driven by the rapid expansion of solar and wind power. Asia drove most of the growth, but the world still needs to triple capacity by 2030 to meet COP28 goals.

Why is investment needed now?

• Energy security and price stability. Diversifying away from volatile fossil fuels reduces shock risk.
• Grid and storage upgrades. New renewables need smarter grids, more transmission, and storage to balance supply.
• Jobs and domestic industry. Building clean energy supply chains creates skilled work and local value.

What’s trending

According to the IEA, global spending on low-emission energy has almost doubled over the past five years, with solar alone projected to reach $450 billion in 2025, the biggest share of energy investment worldwide. Emerging economies are adding solar paired with batteries thanks to falling costs.

Where governments can lead

1. Modernize grids. Fund transmission “backbones,” advanced metering, and interconnections to unlock new projects.
2. Finance storage at scale. Offer concessional loans and auctions for utility-scale batteries and pumped hydro.
3. Reduce risks for private investors. Provide guarantees for pioneering projects, expand green banks, and promote blended financing models to attract broader capital.
4. Build local supply chains. Support training, permits, and ports for components and critical minerals.

Expected impact

Strategic and effective public investment can attract private capital and gradually boost productivity over the long term. It helps lower pollution, improves public health, and enhances energy self-reliance.

Sector 2: Digital Infrastructure & Technology

The digital economy now touches every sector. Mobile technology and related services add about $6.5 trillion to the global economy, and 5G networks continue to grow across more regions. By 2025, close to one-third of the global population is predicted to be connected to 5G services.

Why is investment needed now?

• Close the digital divide. Rural and low-income areas still lack reliable, affordable broadband.
• Compete in AI and chips. Countries are competing to expand computing power, construct data centers, and increase semiconductor production capacity.
• Protect critical systems. Cybersecurity is a public good that markets underfund.

What’s trending

AI is transforming infrastructure. Power-hungry data centers are scaling fast. Goldman Sachs Research estimates that global data center electricity demand will grow by 165% by 2030 compared to 2023 levels.

At the same time, countries and firms are announcing gigawatt-scale AI data centers. Reports indicate that OpenAI aims to develop a 1-gigawatt data center in India under its broader “Stargate” project, along with several other large-scale initiatives in progress. Local authorities in Tasmania also cleared a large AI data-center project tied to renewable power. These moves point to a global rush to add compute, grid capacity, and clean energy for AI.

On the hardware side, governments are onshoring chips. In the U.S., the CHIPS and Science Act unlocked $50 billion for semiconductor R&D and manufacturing programs. Industry groups tally $600B+ in broader U.S. supply-chain commitments announced since 2020.

Where governments can lead

1. Universal high-speed access. Fund fiber and 5G/6G in underserved regions; use open-access models to spur competition.
2. AI-ready infrastructure. Plan for grid upgrades, data-center siting, and water use standards tied to clean power.
3. Strengthening semiconductor resilience. Collaborate on building fabs, improving packaging, and developing skilled talent, while forming strong partnerships with reliable global allies.
4. Cybersecurity baselines. Set minimum standards for public services and critical infrastructure, with shared threat intel.

Expected impact

Advanced networks, semiconductors, and computing power are driving productivity gains across many sectors, ranging from agriculture to financial services. Public outlays here can unlock private investment, raise wages, and improve service delivery at scale.

Sector 3: Healthcare & Biotechnology

Health is economic infrastructure. Aging populations, chronic disease, and new pathogens strain systems. OECD datasets show health spending taking a large and rising share of GDP across advanced economies.

Why is investment needed now?

• Access and equity. We must narrow gaps in primary care, diagnostics, and essential medicines.
• Preparedness and R&D. The world needs faster vaccine platforms, better surveillance, and secure supply chains.
• Domestic capability. Dependence on a few import sources risks shortages in crises.

What’s trending

In May 2025, the World Health Assembly approved the Pandemic Agreement (WHA78.1), a framework designed to enhance global prevention, preparedness, and response efforts. This signals a coordinated push to finance readiness, share data, and build manufacturing surge capacity.

Governments are also funding biotech innovation that serves public needs,mRNA improvements, antimicrobial resistance tools, and decentralized trials. These areas align with the Agreement’s focus on equitable access and rapid response.

Where governments can lead

1. Primary care first. Expand clinics, telehealth, and community health workers; tie funding to outcomes.
2. Bio-R&D missions. Co-fund vaccine platforms, novel antimicrobials, and rapid diagnostics with milestone payments.
3. Resilient supply chains. Incentivize regional production of APIs, generics, PPE, and cold-chain capacity.
4. Data and digital health. Build secure health data rails and standards to support AI-driven insights while protecting privacy.

Expected impact

Health investment raises labor force participation, reduces long-run costs, and builds social resilience. When crises hit, prepared systems save lives and protect economies. Public investment multipliers are especially strong when projects are well-chosen and transparent.

Conclusion

We face a clear choice. We can wait and react. Or we can invest with intent. Renewables and grids cut risk and lower bills. Digital infrastructure powers AI, chips, and inclusive growth. Healthcare and biotech protect our people and our productivity. The evidence is obvious, and the pace of progress is rapidly increasing. With bold, targeted action in these Three Sectors Ripe for investment, we can crowd in private capital, build durable industries, and set up the next decade of inclusive growth.
