Net-Zero Energy & Renewables
Net-zero energy use is the ability of a building to supply its own energy over the course of a year by using renewables (typically onsite renewables, though some definitions include offsite procurement).
Alternative energy sources like photovoltaics are becoming more affordable, increasing the possibility that a building project can achieve net-zero energy. And as more buildings use renewables along with storage technologies, there are opportunities to harmonize with the grid and use more renewable energy from there as well.
