Electricity from renawables (such as wind, hydro, solar or wood)

The emission factor for electricity can be reported as life cycle (cradle-to-grave) or in-use emissions. When calculating the emissions of purchased energy for a company, the in-use emission factor should be used. The in-use emissions for renewable energy are zero. Renewable energy sources also have life-cycle emissions, which however are typically lower than the emissions from electricity produced from fossil fuels.
