Overview

Almost half of San Antonio’s GHG emissions come from the sources that supply our buildings with energy. Reducing the carbon impact of our energy generation is one of the single most impactful actions we can take to slow climate change. In partnership with CPS Energy and with assistance from the American Cities Climate Challenge, San Antonio is focusing on a transition from fossil fuel energy sources to a less carbon-intensive portfolio.

The graph below displays the source of San Antonio’s electricity generation throughout the years. In order to power homes and businesses, a combination of renewables, coal, gas and nuclear are utilized.

Energy Benchmarking

The City’s Climate Action & Adaptation Plan includes a slate of mitigation strategies aimed at preventing emissions from greenhouse gases. One of the mitigation strategies under the theme of reducing energy consumption is a commercial and multi-family benchmarking and disclosure ordinance. Energy benchmarking is the process of regularly measuring a building's energy use, tracking its performance over time, and comparing its performance to that of similar buildings.
