Transitioning from traditional fossil fuels to renewable energy sources is becoming increasingly crucial in today’s world. The International Energy Agency (IEA) reports that global renewable power generation capacity is expanding at an unprecedented rate, with renewable energy projected to surpass coal as the leading source of electricity worldwide by 2025. Wind and solar photovoltaic (PV) power generation are expected to overtake nuclear power by 2025 and 2026, respectively, while 68 countries are set to have renewables as their primary power source by 2028.

Driving Forces Behind Renewable Energy Developments

During the United Nations Climate Change Conference (COP28) in 2023, countries set a target to triple global renewables power capacity by 2030. Policies aimed at achieving decarbonization, combating climate change, and reaching net-zero emissions are crucial drivers in this transition, as highlighted by the IEA.

Various public policy measures worldwide, such as the European Union’s Green Deal Industrial Plan, India’s Production Linked Incentives (PLI), and the Inflation Reduction Act (IRA) in the US, are propelling the adoption of sustainable energy. China, a major player in renewable energy capacities, has exceeded its 2030 targets ahead of schedule, particularly in onshore wind and solar photovoltaic projects.

Expansion of Renewable Energy by Type

Solar Power

In 2023, solar photovoltaic energy represented the majority of renewable capacity additions globally, with growth attributed to both utility-scale projects and distributed PV systems. Ongoing government support, including incentives like net-metering programs and tax credits, is vital for the expansion of solar power. Advances in solar panel technology and manufacturing are enhancing the efficiency and affordability of solar energy generation, with solar PV expected to dominate energy production in green hydrogen, supporting various industries in decarbonization efforts.

Wind Power

Policies continue to drive wind energy expansion worldwide, with significant growth in China but varying projections in Europe and North America. Initiatives like the European Union’s Wind Power Action Plan and the US investment in floating wind farms aim to boost wind power capacities. To meet ambitious renewable energy goals, sustained annual growth rates for wind power are essential.

Hydropower

While hydropower remains a significant energy source, new additions are expected to decrease due to development slowdowns in key regions like Europe, China, and Latin America. With fewer countries offering support for hydropower compared to wind and solar, achieving growth targets under the Net Zero Emissions Scenario will require focused efforts.

Biofuel

Biofuel expansion, driven by supportive policies in emerging economies, particularly Brazil, is advancing, primarily in the transportation sector. However, challenges persist in regions like the EU and US due to costs and the rise of electric vehicles. The combination of biofuels and electric vehicles has the potential to offset significant amounts of oil consumption.

Geothermal Energy

Advancements in geothermal technologies are opening up opportunities for wider adoption, but further policy support is needed to unlock its full potential. Despite its reliability, geothermal energy projects face financial challenges, hindering rapid growth. Efforts to scale and reduce costs could facilitate increased utilization of geothermal energy.

Technological Support for Renewable Energy Integration

As renewable energy deployment escalates, technology plays a critical role in ensuring a stable and reliable energy supply. Tools like renewables forecasting platforms, advanced energy storage systems, and intelligent asset management solutions are pivotal in optimizing renewable energy generation and distribution while enhancing energy security.

To actualize a sustainable energy transition, align your strategic roadmap with operational efficiency and explore innovative solutions like the IBM Environmental Intelligence Suite for Energy and Utilities and the IBM Maximo Application Suite for Energy and Utilities.
