How is the term “B100” defined in the context of oil usage in Maine?

In the context of oil usage in Maine, "B100" specifically refers to a biodiesel blend that contains 100% biodiesel. This means that B100 is made entirely from renewable resources, typically derived from vegetable oils or animal fats, and does not contain any petroleum. The designation "B" stands for biodiesel, and the number signifies the percentage of biodiesel in the fuel blend.

By using B100, users can reduce their carbon footprint and reliance on fossil fuels since it is a sustainable alternative that contributes to lower greenhouse gas emissions. This high percentage of biodiesel makes B100 a fully renewable fuel option, distinguishing it from blends that contain lower percentages of biodiesel, such as B20, which has only 20% biodiesel mixed with 80% petroleum diesel. Understanding the definition of B100 is crucial for those involved in oil usage and environmental conservation efforts in Maine, as it highlights the transition towards renewable energy sources in the region's fuel consumption.
