**8. Recommendations**

This chapter discussed the use of hourly, seasonal, monthly and annual emission factors in order to demonstrate the daily fluctuations from the electricity generation sector. In the future, peak, weekly and marginal emission factors could be developed in order to increase the accuracy of emission estimations. In addition, emission factors could be updated every year in order to allign with current renewable technology analysis models and electricity generation mix.
