Greenhouse gas emissions from air conditioners are expected to climb as economic growth drives efforts to control both temperature and humidity, according to an analysis by scientists from the National Renewable Energy Laboratory and Xerox PARC. The research, which explores the environmental impact of controlling humidity, appears in the journal Joule as "Humidity's impact on greenhouse gas emissions from air conditioning." While the energy used to power air conditioners has clear implications on greenhouse gas emissions, the impact from removing moisture from the air has escaped in-depth study until now. The researchers showed that controlling humidity is responsible for roughly  half of the energy-related emissions, with the other [...]
