Our lawns cool off surrounding areas through the evapotranspiration process. Lawn areas cool the air as water evaporates from the blades of grass. As much as 50% of the Sun's heat falling on the turf will be absorbed and eliminated through transpiration.
Through photosynthesis grass absorbs sunlight to produce energy. Grass plants will take in the Sun's heat during the day and release it slowly at night, helping to moderate temperatures
The front lawns of eight homes can have the cooling effect of 70 tons of air conditioning, greatly reducing energy needs and the burning of fossil fuels needed to produce it. It has been estimated that strategic planting of lawns and landscape plants could reduce the energy required for air conditioning by 25%.
The cool sensation of walking barefoot through the grass is very real. Temperatures on lawn surfaces can be 10 to 14 degrees cooler than on concrete or asphalt. Green spaces can play a big role in modifying temperatures and controlling climate.
