Introduction
Variable Renewable Energy (VRE) is a key player in the global transition to cleaner and more sustainable energy sources. VRE includes renewable energies, such as wind and solar power, which generate electricity intermittently based on environmental conditions. This article explores VRE, highlighting its intermittent nature and its crucial role in shaping modern energy systems.
The intermittent nature of variable renewable energy (VRE)
Wind Turbines
Wind turbines convert wind’s kinetic energy into electricity. However, the variable wind speed poses challenges in maintaining consistent energy output. Efficiently managing this intermittency is crucial for effective utilization of wind power in the energy grid.
Solar Power
Solar panels use sunlight to generate electricity, but their effectiveness depends on daylight availability and weather conditions. The intermittent nature of solar power requires strategic planning to address fluctuations and ensure a reliable energy supply.

Managing variability in variable renewable energy (VRE)
Two key strategies are energy storage systems and smart grid technologies with demand response mechanisms. Smart grid technologies and demand response mechanisms help balance the intermittent nature of VRE, enhancing overall grid stability and reliability.
The Role of Energy Storage Systems in variable renewable energy
In order to effectively manage the variability of VRE sources, innovative solutions are required, with energy storage systems playing a pivotal role. These systems store excess energy generated during peak production periods and release it during low-production or high-demand periods. This approach helps balance the intermittent nature of VRE, enhancing grid stability and reliability.
Smart grid technologies and demand response for variable renewable energy
