Renewable energy –  conversion and storage

Renewable energy is energy obtained from non-finite or non-exhaustible natural resources on the planet, such as wind and sunlight. Renewable energy is a viable alternative to traditional fossil-fuel-based energy, and it is generally less harmful to the environment. Renewable energy sources are seen as a viable alternative to fossil fuel depletion. Renewable energies are a great alternative for remote locations as the energy sources are plentiful (namely, solar radiation and wind) and the grid is unavailable. Hybrid renewable energy systems (HRESs), which are interconnected with a variety of renewable and nonrenewable energy sources and storage devices, have sparked widespread concern about how to deal with renewable energy's unpredictability, provide reliable electricity, and reduce reliance on fossil fuels.
