Summarize the following in 80 words: The global shift to renewable energy has accelerated dramatically in the past decade, driven by rapidly falling costs of solar and wind generation, advances in battery storage technology, and aggressive policy support across the European Union, China, and recently the United States. Solar PV capacity alone has grown by over 20% annually since 2015. However, grid infrastructure investment has lagged behind generation capacity, creating bottlenecks. Analysts warn that without parallel investment in transmission and storage, renewables may not scale fast enough to meet decarbonization targets set for 2030 and 2050.
