Abstract Transitioning to renewables is critical address the Caribbean's vulnerability imported fossil fuel price volatility and concerns about climate change. This study presents a first‐of‐its‐kind comprehensive analysis of 17 illustrative pathways varying impact e‐fuel imports, grid interconnections an accelerated energy transition towards carbon neutrality by 2050. The research method based on techno‐economic principles for designing cost‐optimal system. An optimisation tool used, LUT Energy System Transition Model, analyse various pathways. finds that high uptake in Caribbean systems significantly lowers costs enhances reliability, crucial building competitive resilient economies. Renewable dominated show 7–24% lower cumulative compared alternatives, with integration reducing 1–10%. Accelerated incur 3–12% higher than complete defossilisation Solar photovoltaics, wind power, batteries, electrolysers are pivotal achieving Importing e‐fuels reduces system 7–16% supports local resource use. Offshore renewable overcome land limitations, driving sustainable development vibrant blue economy. High electrification levels energy, sector coupling, Power‐to‐X solutions enhance efficiency flexibility. Given dominance solar could be more appropriately called ‘Solar‐to‐X Economy’. contributes international perspective islands.

Air pollution, global warming, and energy insecurity are three major problems facing the world. This study first examines whether 149 countries can transition 100% of their business-as-usual (BAU) all-sector to electricity heat obtained from wind-water-solar (WWS) sources solve these problems. WWS eliminates energy-related air pollution deaths CO2-equivalent emissions while reducing end-use needs by ∼54.4%, annual costs ∼59.6%, social (energy plus health climate) ∼91.8% among nations, giving energy- social-cost payback times 5.9 0.78 years, respectively. Conversely, "all-of-the-above" policies promoting carbon capture (CC) and/or synthetic (as opposed natural) direct (SDACC) reduce or offset CO2 trigger, with full penetration CC/SDACC across countries, $60–80 trillion/y in cost, 9.1–12.1 cost only 1.1–25.6% lower than BAU. Even when all is stored, CC SDACC increase (due inefficiencies not capturing non-CO2 greenhouse gases), needs, equipment relative WWS. Sensitivity tests reinforce this finding. Although extreme, any level increases substantially versus Thus, should be abandoned.

Conventional sources of electricity are limited and they pollute the Earth, so it is necessary to think about an additional source in future. Nuclear power one options. Two scenarios using different shares nuclear future described this paper. Scenario 1 describes a moderate increase energy use future, but with tendency for larger over 2050. 2 significant until 2100. Both divided into three sub-scenarios (total six) which technologies analyzed (conventional liquid water reactors, fast breeder reactors molten salt thorium as fuel). In all scenarios, phase-out fossil fuel plants assumed. One part system covered by plants, remaining renewable plants. After 2050, increasing share will be taken RES stocks also analyzed. It calculated that currently known sufficient meet needs six scenarios. The carbon dioxide emissions saved due instead conventional calculated. CO2eq emission savings 87.4% recommended under IPCC. more than sufficient. A calculation economic profitability made relation According calculations, profitable compared other sources. positive from mentioned aspects.
