Describes the primary source(s) for energy produced, sold, or purchased by the organization during the reporting period, or disaggregates another metric in terms of the primary source of the related amount of energy.
Select all that apply:
Non-renewable sources:
Renewable sources:
Other (write-in)
Organizations should footnote all assumptions used, including source of data or disaggregation and any other disaggregations applied.
This metric is intended to capture a description of the primary source(s) of energy produced, sold, or purchased by the organization during the reporting period. Organizations are encouraged to footnote the percentage of their energy in each category.
This disaggregation, applied to another metric, is intended to capture the share of that metric which comes from the selected primary energy source(s). For example, the disaggregation "Renewable, clean sources" when applied to Energy Generated for Sale (PI8706) would include the amount of renewable, clean energy sold by the organization during the reporting period.
Large-scale hydropower is often excluded from the definition of renewable energy. Although water itself is a renewable resource, the natural ecology of rivers is not, and hydroelectric dams can adversely affect aquatic ecosystems. Organizations can refer to the Low Impact Hydropower Institute (http://lowimpacthydro.org) for further guidance on creating low-impact hydropower operations.
