Solar-Powered Cold Storage: Breakthrough Applications of New Energy Technology in the Cold Chain Revolution 

I. Energy Challenges in Global Cold Chain Transformation

(Keywords: cold chain energy consumption, refrigeration carbon emissions, off-grid storage needs)

The International Energy Agency (IEA) 2023 report reveals that global cold chain systems consume 2800 billion kWh annually, with developing countries suffering 23% cold chain disruptions due to inadequate power infrastructure. China's Ministry of Agriculture and Rural Affairs data shows persistent 25%-30% loss rates in agricultural product circulation due to refrigeration failures. In this context, solar-powered cold storage as a renewable energy refrigeration solution is driving profound transformations in global cold chain systems.
