Amount of purchased energy consumed by the organization from renewable sources during the reporting period.
Organizations should footnote all assumptions used.
Renewable energy sources include solar, wind, geothermal, hydro energy, biomass, and other forms. Organizations may refer to the glossary for additional information.
Large-scale hydropower is oftentimes excluded from the definition of renewable energy, since water itself is a renewable resource, but the natural ecology of rivers is not and hydroelectric dams can adversely affect aquatic ecosystems. Organizations can refer to the following source for further guidance on creating low impact hydropower operations: Low Impact Hydropower Institute (http://lowimpacthydro.org).
In some contexts, this metric can serve as an indicator of whether the outcome being sought by an investor or organization is occurring (the WHAT dimension of impact). For more on the alignment of IRIS metrics to the five dimensions of impact, see specific guidance document. No single metric is sufficient to understand an impact; rather, metrics are selected as a set across all dimensions of impact. When possible, the selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.
Metrics identified as "cross-category" are those that are relevant to any IRIS+ Impact Category or Impact Theme (i.e., these metrics are not specific to any particular industry/category or theme).

Material change. Energy Produced On-site: Renewable (OI2496) and Energy Purchased: Renewable (OI3324) replaced Renewable Energy (OEN37). Metric bifurcated in order to increase specificity by distinguishing between purchased and self-produced energy.
August 2009 - IRIS v1.0 Released
New metric. Renewable Energy (OEN37) developed via Original IRIS Working Group.
IRIS Metrics Work Better in Sets
To use IRIS metrics—and the resulting data—to understand impact performance, IRIS metrics should be used and analyzed in generally accepted sets and according to well-defined objectives. IRIS+ gives you access to generally accepted Core Metrics Sets aligned to common Impact Themes and Sustainable Development Goals (SDGs).
