Another key co-benefit of urban forests is their role in energy conservation, for Miami air conditioning demand in particular. Urban forests also provide services to energy conservation by helping reduce energy demand in several key ways. By blocking the sun from buildings, urban forests cool down their area, reducing the demand for air conditioning. Even further, by moving water from the ground upward trees cool the air as water transpires from their leaves.
A 2017 study showed that urban forests in the United States reduced energy demands in their local areas by 38.8 million MWh, energy worth 4.7 billion dollars.
