Powering the Future: Rapid Growth in Clean Energy Fueled by Policy, Cost Declines, and Demand

The clean energy industry is experiencing rapid growth, driven by policy support, cost declines, and increasing demand for low-carbon energy sources. According to the International Energy Agency (IEA), clean energy deployment has accelerated since 2019, with annual additions of solar PV and wind growing 85% and 60% respectively in 2023[2]. This growth is expected to continue, with the US Energy Information Administration projecting renewable deployment to grow by 17% to 42 GW in 2024, accounting for almost a quarter of electricity generation[1][3].

Key trends shaping the industry include the reshoring of supply chains, with companies investing in domestic manufacturing to capitalize on tax credits and meet demand for renewable energy sources. Deloitte reports that since the Inflation Reduction Act passed, companies have announced $91 billion of investments in over 200 manufacturing projects, including solar, storage, wind, and hydrogen projects[3]. This domestic manufacturing revival is expected to increase transparency and resilience while decreasing emissions and exposure to geopolitical risks.

Corporate renewable procurement is also driving growth, with 30 companies joining the RE100 initiative in the first 10 months of 2023, growing the membership to 421. Big technology companies are leading the way, accounting for most of the procured capacity, and are expected to continue driving demand for clean electricity in 2024[3].

Regulatory boosts, including historic investments in renewable infrastructure, are expected to help address grid constraints and support the growth of renewables. The IEA notes that clean energy has grown twice as fast as fossil fuels since 2019, with the production of low-emissions electricity growing by around 1,800 TWh, despite disruptions to hydro power and nuclear power[2].

Looking ahead, McKinsey's Global Energy Perspective 2024 projects that renewables will make up the bulk of the power mix by 2050, accounting for 65 to 80% of global power generation, driven by the lower cost of renewable energy sources[5]. Solar is expected to be a key driver of growth, with the IEA reporting that solar PV capacity additions reached almost 540 GW in 2023, with China accounting for the majority of both solar and wind capacity additions[2].

In conclusion, the clean energy industry is experiencing rapid growth, driven by policy support, cost declines, and increasing demand for low-carbon energy sources. Key trends shaping the industry include the reshoring of supply chains, corporate renewable procurement, and regulatory boosts. As the industry continues to grow, it is expected to play a critical role in meeting global decarbonization goals and avoiding the worst impacts of climate change.
