Step aside, fossil fuels — everyone is going solar. With eco-houses and trains now on the market, we might as well redesign as much as we can into solar. This is where electricity-generating greenhouses are stepping in.
Electricity-generating solar greenhouses utilize Wavelength-Selective Photovoltaic Systems (WSPVs), a novel technology that generates electricity more efficiently and at less cost than traditional photovoltaic systems… WSPVs absorb some of the blue and green wavelengths of light but let the rest through, allowing the plants to grow.
In testing a variety of plant species, researchers at UC Santa Cruz found that 80% remained unaffected by changes. The remaining 20%? They actually grew better under the building’s bright magenta windows.
“If greenhouses generate electricity on site, that reduces the need for an outside source, which helps lower greenhouse gas emissions even more,” said [professor Michael] Loik. “We’re moving toward self-sustaining greenhouses.”
The greenhouse uses 5% less water — a success, taking into account that greenhouses occupy 9 million acres of land. And just when you thought things couldn’t get any better, the system costs 40% less than traditional means. Clearly, percentages have demonstrated a win-win situation for these buildings, which will hopefully bring users 100% satisfaction.
