Self-sustaining greenhouses : Solar greenhouses generate electricity and grow crops at the same time
"Smart greenhouses" can capture solar energy for electricity without reducing plant growth. Electricity-producing solar greenhouses use WSPVs, a new technology that produces electricity more efficiently and cheaply than traditional photovoltaic systems. These greenhouses are equipped with transparent roof panels incorporating a bright magenta luminescent dye that absorbs light and transfers energy to narrow photovoltaic strips, where electricity is generated. The plants are sensitive not only to the intensity of the light but also to the color WSPVs absorb some of the blue and green wavelengths of light, but let the rest pass, allowing plants to grow.
First harvests of tomatoes and cucumbers grown in energy-producing greenhouses were as healthy as those in conventional greenhouses, noting that "smart" greenhouses are very promising for dual-use farming and renewable electricity generation .
"We have demonstrated that" smart greenhouses "can capture solar energy for electricity without reducing plant growth, which is very exciting," said Michael Loik, professor of environmental studies at the University of California in Santa Cruz. appears in the current issue of Earth's Future magazine by the American Geophysical Union.
If greenhouses produce electricity on the site, it reduces the need for an outside source, which further reduces greenhouse gas emissions. We are going to self-sustaining greenhouses.
Awesome! Wat better than than things that.
