The carbon intensity of grid electricity delivered to Juntos Farm was 549.7 g CO₂/kWh, nearly double the Spanish national average of 293 g CO₂/kWh as reported in open-source. This is largely due to Ibiza’s grid being powered mainly by fossil fuels, especially natural gas, compared to the mainland’s more diverse mix, including renewables like wind and hydro.
By contrast, when operating at full capacity, the 67.2 kW rooftop solar installation reduced that figure to just 26 g CO₂/kWh — a 95% reduction in emissions. Juntos Farm highlights that this 95% reduction does not refer to overall energy consumption, but to the carbon footprint associated with the energy consumed when it's sourced from solar panels instead of the grid. This analysis is specific to June 2025, when solar panels operate at peak performance, and it’s based on the scheduled output of the rooftop installation and a simplified model of thr electricity consumption patterns.
This isn’t just data, it’s actionable insight that helps farms like Juntos plan smarter energy strategies to decrease their carbon emissions.
