What do these values mean?
Electricity Generated (Megawatt-hours) - Approximate electricity generated. One megawatt-hour powers roughly 33 homes for a day.
Equivalent Homes Powered - Electricity generated divided by the number of homes in the area, assuming average daily electricity usage.
Home Energy Savings - Percentage of daily electricity cost saved by an average household with an average-sized solar array on its roof versus using power only from the grid.
Solar Power Index (0 to 10) - Daily solar power potential scaled to a maximum of 10. Maximum value corresponds to clear sky with average atmospheric conditions (aerosols and water vapor content) on the date.
Wind Power Index (0 to 10) - Daily wind power potential scaled to a maximum of 10. Maximum value occurs when all turbines in the geographic area during the entire forecast period operate at rated capacity. A typical wind turbine operates at rated capacity at wind speeds above about 30 mph and shuts down at wind speeds of about 55 mph.
CO2 Avoided (equivalent) - The tons of CO2 that would have been emitted on average by fossil-fuel power plants operating in the state to produce the same amount of electricity as generated from the sun or wind.
Car Miles (equivalent) - The number of miles an average car would need to be driven to emit the same amount of CO2 as in the 'CO2 Avoided' estimate.
Trees Planted (equivalent) - The number of tree seedlings planted and grown for ten years that it would take to absorb the same amount of CO2 from the air as in the 'CO2 Avoided' estimate.
Smartphones Charged (equivalent) - The number of typical smartphones that could be charged using the amount of electricity generated from the sun or wind.
DMA - Television Designated Market Area, as defined by Nielsen.
Region - The specific eGRID (Emissions & Generation Resource Integrated Database) region as defined by the EPA. See methodology for discussion of eGRID regions.
