Energy-Efficient Retrieval-Augmented Generation: A Systematic Review of Retrieval, Reranking, Caching, and Context-Management Strategies

Retrieval-Augmented Generation (RAG) has become a standard paradigm for grounding large language models (LLMs) in external knowledge, but typical deployments introduce substantial energy, latency, and cost overhead due to expensive retrieval and context-processing pipelines. Recent work in "Green AI" and sustainable ma...
