Abstract: The energy transition required to build a sustainable climate-neutral global economy depends on an increase in the share of non-conventional sources in electricity generation. The geopolitics of the world is shifting from petro-economies (fossil-fuel based) to electro-economies (critical mineral based). The current study hypothesizes that transitioning from fossil fuel-based electricity generation to renewable energy (RE) sources is one of the most viable strategies for mitigating greenhouse gas (GHG) emissions and criteria pollutants, thereby protecting the environment from irreversible damage caused by climate change and worsening air quality, since RE technologies do not rely on combustion processes which substantially eliminate the release of harmful emissions. Therefore, the current study employed Life Cycle Assessment (LCA) approach to evaluate impact of energy transition in the electricity sector. The technical boundary is defined as a "Gate-to-Gate" focusing on the combustion phase, with a spatial boundary centered on Andhra Pradesh, India. This region utilizes energy from diverse electricity segments and further leverages Renewable Energy Share (RES) in the electricity mix. The functional unit selected for quantifying impacts was 1 kWh. The air emissions generated from 1 kWh of electricity generation were obtained from the Ecoinvent v3.3 database for different sources, including thermal power plants (Hard Coal and Natural Gas Combined Cycle), Wind turbines, Solar power, and Hydropower plant (Run-of-river, Pumped storage, and Reservoir type alpine region), present in the state. To test the hypothesis, midpoint impact indicators—Global Warming Potential, Photochemical Ozone Formation Potential, and Terrestrial Acidification Potential—were assessed. Endpoint evaluation further analyzed impacts on human health (measured in Disability-Adjusted Life Years) and ecosystems (terrestrial and freshwater species loss) to provide a comprehensive understanding of the environmental benefits of adopting RE technologies. The findings highlight that the environmental impacts associated with electricity generation have decreased, with Andhra Pradesh mitigating substantial emissions through an increased share of renewables in its electricity mix. This study validates the state's commitment to a clean energy transition and its alignment with Sustainable Development Goals (SDGs) related to clean energy and the environment. Additionally, it analyses several policy measures that are in place to encourage adoption of renewable energy and further highlights the drivers and barriers to their inclusion in the electricity mix.
