China Renewable Energy Investment: Solar, Wind, Hydrogen, and the Green Transition

China's continued construction of coal power plants alongside massive renewable energy investment reflects several practical realities of its energy system: grid stability is the primary concern, as solar and wind are intermittent sources that cannot yet provide reliable baseload power 24 hours a day, and China's grid requires firm capacity to handle demand peaks and prevent blackouts; coal plants under construction use ultra-supercritical technology with 45-47 percent thermal efficiency, significantly cleaner than older plants and approaching the theoretical maximum for coal combustion; many new coal plants are actually replacing older, more polluting units under China's policy of building large, efficient plants while shutting down small, dirty ones; China's industrial base, particularly steel, cement, and chemical manufacturing, requires reliable 24/7 power that renewables cannot yet guarantee at industrial scale; energy security concerns drive diversification, as China imports over 70 percent of its oil and relies on coal as its only domestically abundant fossil fuel; and the reality is that China's coal consumption as a share of electricity generation has already declined from 75 percent in 2010 to approximately 55 percent in 2025, and is projected to fall below 40 percent by 2035 under current trajectory. China's approach is pragmatic: build massive renewable capacity while maintaining coal as an insurance policy, then phase out coal plants as storage technology improves and renewable penetration increases.
