This illustration shows a triboelectric nanogenerator developed by researchers in China that harvests electricity generated from the wind-blown fluttering plastic strips. The design allows researchers to scavenge wind energy as light as a breeze. Credit: Xin Chen, Xiaojing Mu, and Ya Yang Most of the wind available on land is […]

This graphical abstract summarizes how this work performs a comprehensive techno-economic analysis worldwide for photovoltaic systems using a combination of bifacial modules and single- and dual-axis trackers. The researchers found that single-axis trackers with bifacial modules achieve the lowest LCOE in the majority of locations (16% reduction on average). Yield […]
