“…The subsequent economic stimulus, environmental preservation, and improvement to social system are pillars of sustainability. Several studies have assessed the renewable energy targets for specific regions separately, e.g., the USA [3], China [4], India [5], Malaysia [6,7], Taiwan [8], Germany [9], Turkey [10,11], The Netherlands [12] and Spain [13,14], or multi-countries, e.g., the Gulf Cooperation Council (GCC) countries [15], South Asian Association for Regional Cooperation (SSARC) countries [16], BRICS countries [17], and European Union (EU) [18,19].
