Read moreCan consumers save the planet by just buying green?
A doctoral dissertation states that awareness-raising for consumers and eco-labels for products are important, but they are not enough. Government- and market-promoted green consumerism operates as a peripheral activity that is only a safeguard against the most visible, damaging and immediate environmental and social problems.

Read moreA new method to automatically estimate rooftop solar potential
The progress of rooftop solar installations is often slowed by a shortage of trained professionals who must use expensive tools to conduct labor-intensive structure assessments one by one. Now, researchers are proposing a new, data-driven approach that uses machine learning techniques and widely available satellite images to identify roofs that have the most potential to produce cost-effective solar power.
