Contribution of renewable energy technologies in combating phenomenon of global warming and minimizing GHG emissions

Abstract

The energy derived from fossil fuels significantly contributes to global warming (GW), accounting for over 75% of global greenhouse gas emissions and approximately 90% of all carbon dioxide emissions. It is crucial to rely on alternative energy from renewable energy (RE) to mitigate carbon emissions in the energy sector. Renewable energy sources have the potential to eliminate carbon from 90% of electricity generation by 2050, greatly reducing carbon emissions and helping alleviate the impacts of GW. By emphasizing the concept of zero emissions, the future of renewable energy becomes promising, with the possibility of replacing fossil fuels and limiting global temperature rise to 1.5 ℃ by 2050. In this article, renewable energy technologies and their role in various areas to combat GW are explored, examining trends and successes in supporting renewable energy policies and exploring available options to mitigate the effects of climate change and achieve a clean energy future. Moreover, RE offers a clean and sustainable alternative to fossil fuels, reducing reliance on them and minimizing greenhouse gas emissions. This paper also highlights the efforts of leading countries, including China, the United States, India, and Germany, in developing and utilizing renewable energy. These countries’ renewable energy strategies reflect their commitment to combat global warming and reduce harmful emissions for the well-being of present and future generations.
