This year, 2023 4th Asia Conference on Renewable Energy And Environmental Engineering has been successfully held in hybrid mode (both in-person and virtual). On behalf of organizing committee, we would like to thank everyone for your participation. After three years of pandemic, we're finally able to hold the conference physically this time, although only part of it, the participants are all very glad to be able to communicate face to face at the conference, which is definitely a memorable moment for all of us. We're also very grateful for those who participated in the conference virtually, we hope we can catch up with all of you next year in Singapore.
The accepted and presented papers of AREEE 2023 will be published in regular issues of International Journal of Environmental Science and Development http://www.ijesd.org/list-176-1.html with open access.
