Renewable Energy Is Moving Toward the Centre of Global Electricity Markets

The Renewable Market Is Changing

The renewable energy market is no longer a small part of the electricity industry. Solar and wind have become major sources of new power capacity.

The IEA reports that clean-energy technologies have experienced rapid growth over the past decade. The combined market value of selected clean-energy technologies reached nearly USD 1.2 trillion in 2025. 

Cost Is Becoming More Important

Government policy helped create the clean-energy industry.

However, technology costs are becoming increasingly important.

The IEA reports that around 80% of global solar PV and wind generation occurs at lower levelised costs than coal or gas.  That improves the commercial case for renewable projects.

Electricity Demand Is Also Growing

The global electricity system is facing rising demand. Electric vehicles need electricity.

Data centres need electricity. Air conditioning is increasing demand in many countries. Industry is becoming more electrified.

This means the world needs more electricity. Renewable energy can help meet part of that demand.

Energy Security Is Another Driver

Climate policy is not the only reason countries are investing in renewables. Energy security matters too. Solar and wind can reduce dependence on imported fuels.

Domestic renewable resources can therefore become strategic assets. This has made renewable energy increasingly relevant to national economic policy.

Manufacturing Is Part of the Market

The renewable energy market includes more than electricity generation. It also includes manufacturing.

Companies produce:

• Solar modules
• Batteries
• Wind turbines
• Inverters
• Heat pumps
• Electrolysers
• Grid equipment 

This creates industrial opportunities.

Trade Is Becoming Important

Clean technologies increasingly move across borders. The IEA says trade remains central to clean-energy manufacturing.

Under its Stated Policies Scenario, global net trade in selected clean-energy technologies could more than double from approximately USD 290 billion in 2025 to USD 620 billion in 2035. 

That means clean technology is becoming an important part of international trade.

Infrastructure Will Decide the Next Stage

There is a challenge. Renewable generation cannot operate effectively without infrastructure. Solar farms need grid connections. Wind farms need transmission. EVs need chargers. Batteries need electricity networks.

In fact, the IEA estimates investment in enabling infrastructure, mainly electricity grids, at about USD 430 billion in 2025.

Future investment will need to remain strong.

What Does This Mean for Africa?

African countries have an opportunity to participate in the renewable energy market. They can develop renewable projects.

African countries can build local installation businesses. They can provide maintenance. They can develop mini-grids. They can potentially manufacture or assemble selected components.

However, investment conditions matter. Clear regulation is necessary. Financing is necessary. Infrastructure is also necessary for them to participate heavily.

EcoGreenPulse Analysis

The renewable energy market is moving from a technology story to an economic story. Companies are competing for market share. Countries are competing for investment.

Manufacturers are competing for supply chains. Consumers are looking for affordable electricity.

Therefore, the energy transition is increasingly connected to industrial policy and international trade.

Conclusion

Renewable energy is becoming an increasingly important part of global electricity markets. Falling costs are helping. Growing electricity demand is helping.

Energy-security concerns are helping. However, the next stage will depend on infrastructure.

Countries that build strong grids and reliable markets will be better positioned to benefit from renewable energy.

The renewable energy market is therefore likely to become even more important to global economic competition throughout the rest of the decade.
