It is unethical for Professional Engineers to design a project that is not sustainable, but costs may prohibit choosing sustainability over conventional construction methods. With PV alone, we get enough sun every 13 minutes and 20 seconds to meet the world’s energy needs all day, every day, but the sun does not always shine. Wind alone can meet our daily needs more than 40 times over, but the wind does not always blow, and it does not blow where we need it most. Many new technologies reduce the demand for energy thus avoiding costs and environmental issues. New technologies, and a few old ones, are making energy storage more practical. Storage can now make renewable energies affordable that were too expensive a few years ago. This session will help you design sustainable, cost-effective projects.
