Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.
Research was conducted in a growth chamber that compared the growth of spinach in three conditions: under a thin solar panel, under a thick solar panel, and uncovered. Spinach plants under solar panels consumed up to 17 per cent less water — and though their growth was slower, the plant's overall health wasn't affected. And while they grew, the plants kept the area underneath the panels cool, which improved the solar panels' efficiency.
New Jersey’s Canoe Brook Water Treatment plant produces 14 millions gallons of drinking water a day. Each one of those gallons weighs around 8 pounds , so it’s quickly apparent that a large amount of energy is needed to move water from a reservoir to the treatment plant and into the 84,000 homes and businesses that the New Jersey American Water Company serves in the area. So the water utility partnered with NJR Clean Energy Ventures, the renewable energy subsidiary of the natural gas firm New Jersey Resources, for a solution. NJR Clean Energy Ventures built a vast array of solar panels, linked them together, and placed them on the surface of the water at Canoe Brook Reservoir.
“You shade the plant that you're growing with a partially transparent solar cell. It provides a little microclimate underneath it, so it conserves water, and then you get more growth,” Pearce explained. Vertical or movable solar panel options allow for plants like corn or wheat to grow high or for tractors to manoeuvre around crops, Pearce added. Outside of fields, solar panels can also be attached to greenhouses roofs or potentially even floated on bodies of water.
Mindorff discussed the benefits of agrivoltaics, which he described as a hybrid agricultural system that maximizes land use and reduces water consumption while providing clean and affordable energy. Among the benefits is the potential to increase crop yields, while reducing water and fertilizer requirements as well as provide growers with additional income generated through selling solar electricity.
