In hot places like Thailand, cooling buildings uses a lot of energy. Scientists looked at using heat pumps in the ground to cool spaces, comparing them with regular air-based ones. They tested this in Thailand for two months and found that ground heat pumps used about 17% to 18% less electricity than air heat pumps. The researchers also found that making heat pumps locally and as the region's economy grows could be good for using ground heat pumps in the future, not just in Thailand but also in other Southeast Asian countries. So, using ground heat pumps could save energy and reduce carbon dioxide emissions in tropical places.
