How Much CO2 is saved per Gigawatt of renewable energy produced?

The estimated emission reductions achieved through the distribution of 1.0 GWh of lithium batteries for energy storage, we need to consider the emission factors associated with peak demand electricity generation.

According to the U.S. Environmental Protection Agency (EPA), the average emissions intensity of grid electricity in the United States is approximately 0.997 metric tons of CO2 per MWh (megawatt-hour).

Converting the 1.0 GWh of renewable energy to MWh:

1.0 GWh * 1,000 = 1,000,000 MWh

1,000,000 MWh * 0.997 metric tons of CO2 per MWh = 997,000 metric tons of CO2

According to the U.S. Environmental Protection Agency (EPA), the average passenger vehicle emits about 4.6 metric tons of CO2 per year. The emissions reduction of 997,000 metric tons of CO2 is equivalent to taking approximately 216,920 cars off the road for one year, approximately 208,116 average U.S. households' electricity consumption for one year, 1,108,703 round-trip flights between New York and Los Angeles, or 207,323 metric tons of coal burned in a power plant.
