Weâve put 1000 miles per month on our SL Leaf and have averaged 3.7 miles/Kwh. At $.09/Kwh super off peak rate and 10% loss from AC to DC, I figure about $27/mo for 1000 miles. Compare the 13 mpg SUV that the Leaf replaced and that saves $300/ mo. in gas ( at $3.90/gal). That savings just about pays for the car lease.
Two other very important components of the water cycle are evaporation and transpiration. These processes return water to the atmosphere as gaseous water vapor. And though they are similar processes, the water comes from different sources.
Transpiration also includes a process called guttation, which is the loss of water in liquid form from the uninjured leaf or stem of the plant, principally through water stomata. Studies have revealed that about 10 percent of the moisture found in the atmosphere is released by plants through transpiration.
