I'm looking to offset the carbon footprint of my wedding.
I'd like to do it by helping out some local community solar projects.
I've calculated that the weddings footprint will be about 23,000 KG of CO2, and that this would be offset by about 37,000 kWh of solar generation (if 1kg of CO2 = 1.64 kWh).
But over what period do I measure those kWH to calculate how much of a contribution to community solar is meaningful? Over 1 year? Over 5 years? And how do I estimate what would be generated over that time period - I know peak will be far from actual, and how many sunny days do you estimate?
What's an appropriate way to calculate the appropriate contribution?
