Summary
Renewable energy generation has gained popularity in the 21st century due to technological advancements in energy generation and efficiency. Several nations are encouraging a subsidy to replace the conventional energy consumption from residential to commercial use sectors, though renewable energy generation compensates around 30% of the global energy consumption. The major reason behind the lack of reaching a higher share of renewable energy generation is mainly attributed to their intermittent and unpredictable energy generation.
This special issue focuses on the current issues in renewable energy generation and feasible solutions to achieve a carbon-free society.
Topics of interest include, but are not limited to:
· Intermittency in solar and wind energy generation.
· Energy storage challenges for uninterrupted renewable energy supply.
· Land use and environmental disruption during the commissioning of new sites.
· Recycling issues after the use of solar, wind, and other renewable energy systems.
· Energy conversion losses at high temperatures.
· The role of Artificial Intelligence (AI) in renewable energy systems.
· Electrical and driverless vehicles.
· Grid integration challenges for remote renewable energy sites.
· Climate vulnerability leading to energy losses.
· Air pollution and deforestation effects related to biomass and bioenergy.
