Study finds perennial biofuel crops’ water consumption similar to corn

A study by a team from the Great Lakes Bioenergy Research Center (GLBRC) has found that perennial biofuel crops’ evapotranspiration does not differ greatly from corn. Evapotranspiration (ET) refers to the sum total of water lost while the plant is growing, either from evaporation through the plant stem itself (a process called “transpiration”), or from water evaporated off of the plant’s leaves or the ground.

UCLA and Lawrence Livermore researchers have found that most climate models overestimate the increase in global precipitation due to climate change.

The absorption of sunlight by water vapor is vital to understand future global precipitation changes.
