Low-to-no carbon footprint
One of the biggest advantages of renewable energy sources like hydrothermal, solar, and the wind is that they produce almost no carbon footprint. The electricity is generated through mechanical energy, and therefore, no chemical reaction is required. This ensures the process has low carbon and greenhouse emission.
It is unlimited
The second-largest advantage of renewable energy sources is that they are infinite. We won’t run out of these sources of energy until the sun or the water runs out. Furthermore, since energy generation is often dependent on mechanical energy production, the water is returned to the environment and can once again be used to generate electricity.
It is the most reliable source of energy
The disadvantage of relying on non-renewable sources is that no one can accurately estimate when they will run out. Since this estimation cannot be made, no country can rely on this type of energy generation model.
On the other hand, renewable sources of energy are unlikely to run out. The Earth is unlikely to stop its rotation, and therefore we will always have wind, waves, and sunlight. This allows countries to build an energy generation model that can be relied upon to provide power in the long run.
It provides high rates of interest (ROI)
Solar panels are a primary example of renewable energy with high ROI. The installation of a solar panel is more expensive than that of non-renewable sources. But, the solar panel can last longer. An average solar panel has a lifespan of 20-25 years.
Furthermore, it requires low maintenance and helps save money. This means the solar panel can easily pay for itself within 4-5 years, while the remaining 20 years can save money that would otherwise go under ‘electrical expenditure’.
It empowers people
The disadvantage of relying on non-renewable sources of energy like fossil fuel is that countries have to rely on each other. Similarly, the average individual is required to depend on the city’s power grid. This is difficult for households in rural areas with no power lines.
However, with the installation of solar panels or wind turbines, any household in the rural area can become independent. Similarly, countries will no longer need to import petrol, diesel, and CNG. With a renewable energy plant, they can become independent.

These are only some of the advantages. Let’s look at the disadvantages of renewable energy.
