This fall, a group of Portland State University researchers will install solar panels over a series of small eco-roofs.
Once relegated to the fringe, interest in solar energy is higher now in the U.S. than it’s ever been, owing to a confluence of factors: rising global demand for energy, increased urgency to find non-polluting power sources, and security concerns about access to energy sources.
For those reasons, solar reflects the “Holy Grail” of renewable energy options. While the world consumes an average rate of 15 terawatts (TW) of energy, experts have identified 600 TW of readily accessible solar output. Solar power is clean and carbon-free, a critical element to reducing current and future carbon emissions, which are a major contributor to global climate change.
Simply put, “Solar energy is going to save the world.”
Well, that's a relief. We can all go back to sleep now.
