The Energy Retrofit Guide for Caribbean Hospitals outlines a three-step process—Find, Finance, and Follow-through—to help healthcare facilities reduce energy consumption. It highlights the high cost of electricity in the Caribbean (averaging $0.38/kWh) as a primary driver for deep energy retrofits, which can reduce energy costs by over 50%. The guide introduces a free online tool for benchmarking and identifying energy efficiency measures (EEMs), and provides a framework for securing financing and managing the technical implementation of retrofit projects.

The document outlines strategies for reducing the energy footprint of the kitchen, focusing on the life cycle of food and the efficiency of appliances. It highlights that refrigerator energy use has dropped over 60 percent in twenty years due to technology and standards, though older models remain costly. For cooking, it argues that habits are more impactful than technology, recommending smaller appliances like microwaves and toaster ovens over conventional ovens. It also emphasizes the environmental benefits of buying local, organic food and implementing composting and recycling to reduce the millions of tons of food and packaging waste entering U.S. landfills.

The report identifies significant energy efficiency opportunities in Thailand's dairy cold chain, particularly in pasteurised milk processing, where best practices could save up to 30% of energy. It highlights that refrigerated transport consumes over 19 million litres of diesel annually and suggests transitioning to electric trucks and optimising load weights. Additionally, ice-making for non-refrigerated distribution presents a 37% energy saving potential. While some facilities have adopted solar PV, the report notes that cold chain data remains fragmented, hindering systematic planning and monitoring.

The World Resources Institute (WRI) evaluated a sludge-to-energy project in Xiangyang City, China, which utilizes high-temperature thermal hydrolysis and anaerobic digestion. The project achieves significant environmental gains, including the recovery of 96% of nitrogen and 99% of phosphorous, and the reduction of greenhouse gas emissions by 95% to 98% compared to landfilling and incineration. Over a 21-year period, the project is expected to produce 45.4 million m3 of natural gas, replacing 60,000 m3 of gasoline and further reducing CO2e emissions by 140,000 metric tons. Economically, the project's success is attributed to a 'government-bank-enterprise' partnership involving the municipal government, KfW Bankengruppe of Germany, and the Export-Import Bank of China, alongside a market-oriented design focusing on the sale of compressed natural gas (CNG) and biochar.
