Residential and commercial buildings utilize cooking stoves and heating furnaces powered by natural gas or heating oil. Additionally, they generate organic waste that decomposes into methane.
Households and offices consume fossil fuels for heating, supplied either through pipelines or delivered by truck to fill on-site tanks.
These buildings also generate waste processed through sewage or garbage collection, which decomposes into methane. While this methane can potentially be captured and used as fuel, it is not always utilized.
According to the EPA, this category excludes electricity generated by power plants but includes “distributed generation” from rooftop solar panels, as data on the generation, consumption, and storage of this energy remains private.
