Corn better used as food than biofuel, study finds

Tue, 20 Jun 2017 14:29:18 EDT ~ Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.

Freshwater from salt water using only solar energy

Mon, 19 Jun 2017 16:54:23 EDT ~ A federally funded research effort to revolutionize water treatment has yielded a direct solar desalination technology that uses energy from sunlight alone to heat salt water for membrane distillation. The technology could provide off-grid water treatment for some of the 1 billion people who lack access to clean water. Find out more...

Sustainable ethanol from carbon dioxide? A possible path

Mon, 19 Jun 2017 16:54:09 EDT ~ A recent discovery could lead to a new, more sustainable way to make ethanol without corn or other crops. This promising technology has three basic components: water, carbon dioxide and electricity delivered through a copper catalyst. Find out more...

Could renewable 'power-by-wire' help fix Chinas air pollution problems?

Fri, 16 Jun 2017 12:17:07 EDT ~ Bringing renewable power by wire from western China to its power-hungry Eastern cities could have benefits for both local air quality and global climate change, new research has found. Find out more...

Dryland cropping systems research addresses future drought and hunger issues

Thu, 15 Jun 2017 21:37:28 EDT ~ The projected world population by 2056 is 10 billion. If researchers succeed in improving the yield potential of 40 percent of global land area under arid and semi-arid conditions, it will lead to a significant contribution to future food security. Find out more...

Global diet and farming methods 'must change for environment's sake'

Thu, 15 Jun 2017 21:32:58 EDT ~ Reducing meat consumption and using more efficient farming methods globally are essential to stave off irreversible damage to the environmental, a new study says. The research also found that future increases in agricultural sustainability are likely to be driven by dietary shifts and increases in efficiency, rather than changes between food production systems. Find out more...
