How are the Avoided Carbon numbers on the dashboard calculated?
We calculate each of the Avoided Carbon Metric in the following manner:
CO2e: Metric tons of avoided carbon, encompassing grid energy not consumed, grid energy displaced by renewable generation, and carbon avoided through the use of batteries to time shift energy across hours.Cars: An estimate of the annual number of gasoline-powered passenger vehicles in the US producing emissions equivalent to those avoided. It's based on the previously calculated avoided emissions, converted to the number of cars using the average vehicle carbon footprint (4.490 tCO2e/vehicle/year).
Trees: An estimate of the number of tree seedlings grown for 10 years in the US. This calculation is based on the avoided emissions calculated above, converted to trees reflecting the average carbon sequestered per urban tree planted (0.060 tCO2e per tree planted)
Explain the calculations done for Digester Dashboards that require assumptions and show the sources for any assumed values.
The calculations done for the Digester Dashboard are as follows:
Scope 1 = (Scope 1 Emissions factor for AD) * (Tonnes Treated)
Trucks Removed = (Trucks removed per gallon of waste treated) * (Gallons Treated)
Avoided emissions - Power Generation = (Avoided emissions factor for power generation by biogas) * (Approx. Electricity Produced)
Avoided emissions - AD of waste = (Tonnes Treated) * (Reducing MSW waste in landfill due to AD)
Relevant sources are as below :
Scope 1 Emissions factor for AD
Trucks removed per gallon of waste treated
Avoided emissions factor for power generation by biogas (with natural gas as the marginal source)
Reducing MSW waste in landfill due to AD - avoided emissions factor
emission_factors_grams_per_wh = { "Petroleum": 1079.55, "Natural gas": 483, "Coal": 961, "Wind": 0, "Nuclear": 0, "Solar": 0, "Hydro": 0, "Other": 0, }
EMISSSION_FACTORS = { "Battery": 0, "Biomass": 60, "Black coal": 892.59, "Brown coal": 1174, "Gas": 578.72, "Hydro": 0, "Liquid Fuel": 1274, "Solar": 0, "Wind": 0, }

Understanding the Widgets
Grid Charging an EV Widget: This widget informs users about the environmental impact of charging an electric vehicle from the grid during specific times of the day (1am-2pm, 7pm-10pm). It shows that this charging pattern results in CO2 emissions equivalent to filling 1,939 balloons, as shown in the picture, highlighting the higher carbon footprint associated with grid power compared to cleaner energy sources.
Today's Energy Usage Widget: This widget provides an overview of the building's total energy consumption for the day, such as 1 MWh, and breaks it down into the percentages sourced from the grid (92%) and from onsite solar (8%), as shown in the picture. It visually displays the building's reliance on grid power versus renewable solar energy.
Today's Energy Flow Widget: This widget illustrates the flow of energy within the building, showing how energy is distributed from the grid (93%), solar panels (3%), and batteries (5%), as shown in the picture. It helps users understand the energy mix and the contribution of renewable sources.
Grid Energy Makeup Widget: This widget breaks down the sources of the grid energy consumed by the building, showing a significant portion from non-renewable sources like black coal (79%) and contributions from renewable sources like wind (13%), as shown in the picture. It underscores the environmental benefits of increasing onsite solar usage by highlighting the current dependency on dirtier energy sources.
Solar Power Usage Advice Widget: This widget advises users on the optimal times to use appliances to maximize solar power usage, suggesting periods when solar generation is highest (12am-1am, 2pm-7pm, 10pm-11:59pm), as shown in the picture. It encourages energy consumption patterns that align with solar availability, promoting a reduction in reliance on the grid.
Solar Generation Widget: This widget tracks the amount of energy generated by the solar panels throughout the day, such as a total of 43 kWh, as shown in the picture. It provides a visual representation of solar production over the past 12 hours, helping users monitor solar performance and identify peak generation times.
Last 24 Hours' Energy Consumption Widget: This widget compares the building's energy consumption from solar and grid sources over the last 24 hours. For example, it shows solar energy usage peaking at certain hours while grid usage is higher at other times, as shown in the picture. This promotes awareness of how solar energy can offset grid consumption.
Quiz Widget: This interactive widget engages users with questions related to renewable energy, such as the role of Tasmania in Australia's renewable energy landscape, highlighting that Tasmania is a leader in hydroelectric power, as shown in the picture. It serves as an educational tool to raise awareness about renewable energy sources and regional contributions.
Avoided CO2 Emissions Widget: This widget quantifies the environmental benefits of solar generation by converting the avoided CO2 emissions into an equivalent number of balloons, such as 5,164 balloons, as shown in the picture. It visually communicates the impact of using solar power instead of the grid, reinforcing the importance of renewable energy in reducing carbon footprints.
