News from the University of California, Santa Cruz, indicates that plants grown in an electricity-generating solar greenhouse perform at least as well or better than plants grown in a conventional greenhouse. Some crops even used less water when grown in the magenta-colored greenhouse, made with Wavelength-Selective Photovoltaic System (WSPV) panels tinted to help them absorb light. The panels transfer the sun's energy to thin photovoltaic strips that turn it to electricity that can be used to power fans and lights in the greenhouse. "If greenhouses generate electricity on site, that reduces the need for an outside source, which helps lower greenhouse gas emissions even more," said environmental studies professor and project leader Michael Loik. "We're moving toward self-sustaining greenhouses."
