It is irrational. Renewable sources are here, are being rapidly deployed and are decreasing emissions.

Global renewable power capacity is expected to double between now and 2030, increasing by 4 600 gigawatts (GW). This is roughly the equivalent of adding China, the European Union and Japan’s power generation capacity combined to the global energy mix. Solar PV accounts for almost 80% of the global increase, followed by wind, hydropower, bioenergy and geothermal. In more than 80% of countries worldwide, renewable power capacity is set to grow faster between 2025 and 2030 than it did over the previous five-year period. However, challenges including grid integration, supply chain vulnerabilities and financing are also increasing.

The increase in solar PV capacity is set to more than double over the next five years, dominating the global growth of renewables. Low costs, faster permitting and broad social acceptance continue to drive the accelerating adoption of solar PV. Wind power faces supply chain issues, rising costs and permitting delays – but global capacity is still expected to nearly double to over 2 000 GW by 2030 as major economies like China and the European Union address these challenges. Hydropower is set to account for 3% of new renewable power additions to 2030. The faster growth of pumped storage plants between 2025-30 leads to a much greater increase in hydropower compared with the previous five years. In 2030, annual geothermal capacity additions are expected to reach a historic high, triple the 2024 increase, driven by growth in the United States, Indonesia, Japan, Türkiye, Kenya and the Philippines.
The forecast for growth in global renewable power capacity is revised down slightly, mainly due to policy changes in the United States and China. The renewable energy growth forecast for the 2025-2030 period is 5% lower compared with last year’s report, reflecting policy, regulatory and market changes since October 2024. The forecast for the United States is revised down by almost 50%. This reflects several policy changes, including the earlier phase out of federal tax credits, new import restrictions, the suspension of new offshore wind leasing and restricting the permitting of onshore wind and solar PV projects on federal land. China’s shift from fixed tariffs to auctions is impacting project economics and lowering growth expectations. Nonetheless, China continues to account for nearly 60% of global renewable capacity growth and is on track to reach its recently announced 2035 wind and solar target five years ahead of schedule, extending its track record of early delivery.

The deployment of renewables has already reduced fuel import needs significantly in many countries, enhancing energy diversification and security. Since 2010, the world added around 2 500 GW of non-hydro renewable power capacity, about 80% of which was installed in countries that rely on fossil fuel imports. Without these renewable additions, cumulative global imports of coal and natural gas in these countries would have been 45% higher in 2023. As a result, countries have reduced coal imports by 700 million tonnes and natural gas imports by 400 billion cubic metres, saving an estimated USD 1.3 trillion since 2010.

Nuclear has a role to play, but it will
not be the sole source of electricity (unless you have a time machine you haven’t mentioned.)
