The Residential Zero Net Energy Transformation (RZNET) program will  assist SDG&E multifamily and manufactured housing customers with navigating their path to zero net energy. 

What is Zero Net Energy(ZNE)?  ZNE is the total amount of energy used by the building on an annual basis is equal to or less than the amount of renewable energy (energy created by sources that are naturally replenished, such as wind, rain, or solar) created on-site.
