Our present need is to reduce or minimize the dependency on fossil fuels through a thorough understanding of the principles and utility of renewable energy along with green technology. It has been considered that renewable energy as an alternate source is the best and cheapest source of energy. The unwarranted usage of fossil fuels has a huge effect on climate change globally. This can be restored by the efficient utilization of renewable energy resources. Efficient utilization of renewable energy resources could minimize the impact of climate change globally. Generally, renewable energy is generated from essentially inexhaustible sources, including wind power, solar power, geothermal energy, tidal energy, biomass energy, and other sources. Sustainability researchers have highlighted the importance of green energy and its immediate impact on the environment. Therefore, transitioning toward green energy is crucial to reducing the global crisis and achieving sustainable development.
