Sustainable Home: Energy Efficiency and Building Electrification

Energy efficiency and building electrification lead to healthier, safe, and more resilient homes. For more information about the City's building decarbonization initiatives, visit

What is building decarbonization? 

Building decarbonization is the process of shifting natural gas use in existing buildings toward clean, energy efficient all-electric buildings. With Alameda Municipal Power (AMP) now providing 100% clean electricity, Alameda's greenhouse gas emissions in homes comes from natural gas consumption. Decarbonization is a three step process of decarbonizing the grid, then reducing energy use, and finally electrifying buildings. 

Building Decarbonization

  • Decarbonize Electric Grid: The first step of building decarbonization is to decarbonize the electric grid. Alameda has already completed this step with AMP providing 100% clean electric energy, beginning in 2020. AMP sources its electricity from a mix of sources such as geothermal, hydroelectric, wind and landfill gas. 
  • Energy Efficiency: Energy Efficiency entails reducing building energy use, energy bills and emissions through weatherization, building insulation and more efficient appliances.
  • Electrify Buildings: Electrifying buildings looks like replacing gas appliances in buildings with electric ones for space heating, water heating, clothes drying, and cooking. 

Where to begin?

Building decarbonization can seem like a big undertaking, as there are a multitude of options. First begin with energy efficiency then move onto  building electrification.
