6 FAQs about [Cairo energy storage payback time]
What is energy payback time?
The energy payback time may also be defined at the useful energy stage (EPT u) as the time required to deliver the same amount of useful energy that could have been delivered by the final energy that was invested in the renewable energy technology.
Does Egypt still rely on conventional energy sources?
According to the rate of increase in the consumption of conventional energy sources in Egypt alongside the CO 2 emissions over the period from 1971 to 2016 (for 47 years as shown in Fig. 1) (The world bank, 2022), it is evident that Egypt is still relying primarily on the conventional energy resources. Fig. 1.
Can batteries solve Egypt's Electricity oversupply problem?
Egypt is exploring the potential of energy storage through batteries to combat our electricity oversupply problem: As Egypt continues to suffer from a major oversupply of electricity, the country is in need of new ways to tackle the issue.
Can Egypt transition from conventional to re energy resources?
This should allow for carrying out an energy transition from conventional to RE resources in Egypt; where a similar analysis has been carried out in Iran and allowed for developing five different energy systems focusing on the underlying RE production and efficiency improvements (Noorollahi et al., 2021).
Are estimated EROIs a power return on investment?
As we use yearly energy flows (annual-flow framework) instead of energy flows over the lifetime of an installation, estimated EROIs may be considered a power return on investment 30.
What is energy payback time EPT F?
At the final energy stage, the energy payback time EPT f may be defined as the time required for an energy system to deliver the energy that had to be invested.
