<br/><br/> ABSTRACT<br/>The transition to a low-carbon energy system is crucial for mitigating climate change <br/>and achieving global sustainability goals. This thesis examines the decarbonization <br/>potential of five major economies and significant polluters, namely the United States, <br/>China, Japan, Germany, and India, focusing on the assessment of two decarbonization <br/>scenarios for global electricity generation. The primary objective is to evaluate the <br/>feasibility and implications of achieving a high share of renewable energy by 2030 and <br/>2050 in these countries.<br/>The thesis presents a comparative analysis of the results obtained for each country, <br/>exploring the CO2 emission reduction and total annual cost implications in 2030 and <br/>2050. To conduct this analysis, the simulation software EnergyPLAN is utilized to <br/>model and simulate energy systems in each country. <br/>The results show that, for the two scenarios, each of the five countries considered in <br/>the study will experience significant reduction in their CO2 emission levels in 2030 <br/>and 2050 compared to 2021. The countries will see their CO2 emissions reduce by up <br/>to 81.1%, 85.14%, 77.21%. 81.66%, and 49.18%, respectively, in 2030. Similarly, the <br/>CO2 emission reductions for each of the five countries listed earlier are 79.76%, <br/>71.17%, 74.51%, 52.42%, and 39.05%, respectively, in 2050. The results also show <br/>that the total annual cost form implementing the second scenario in which storage <br/>systems are not designed for the excess electricity produced is reasonable compared to <br/>the cost in 2021. For example, the cost for USA in 2021 is 367.5 billion USD, 307.1 <br/>billion USD in 2030, and in 2050, and 354.2 billion USD. The results from the <br/>sensitivity analysis show that for an increase in capacity form 100 MW to 200 MW for <br/>each of the major renewable energy systems (RES), the CO2 emissions will reduce for <br/>all five countries. The total cost majorly reduces, or experiences a very slight increase, <br/>for all the RES, except for the concentrated solar power system (CSP). The total cost <br/>of the CSP shows a significant increase for all five countries due to its high installation <br/>and maintenance costs.<br/>The findings of this research contribute to the understanding of the decarbonization <br/>potential of global electricity generation and provide valuable information for <br/>policymakers, energy planners, and stakeholders involved in shaping sustain
