This study presents the recent trends in the transition from fossil fuels towards renewable energy for combating climate change and achieving a net-zero energy target by 2030 as per United Nations Sustainable Development Goal-7 (Energy for All). However, the Net Zero target is difficult to achieve unless effective energy conservation and energy efficiency policies, regulations, and financial investment, are not initiated along with the major energy transition to renewable energy. Therefore, the study's objective is to present the current status of initiatives by different countries including India to address this problem as per the recommendations of various Conference of Parties including COP-29. The case study of India shows that enhanced energy efficiency, energy conservation, effective solar energy policies, and regulations for high energy-consuming sectors like industry, agriculture, buildings, domestic and awareness among society are important for achieving realistic targets. The Chhattisgarh State study identifies the high energy-consuming sectors, leading to a 2.7 million kWh reduction in energy consumption in the past two decades through various initiatives. These measures are leading India towards an efficient Net-Zero energy transition in a realistic way. The study results are of importance for follow-up action in developing and least-developed countries worldwide.
