Duolingo / PTE / IELTS discussion essay.
In the contemporary era, the escalating demand for energy to power factories, households, and, notably, automobiles has underscored the imperative for renewable energy sources. This essay aims to delve into the advantages and disadvantages of these sustainable energy alternatives in comparison to traditional fossil-based fuels.
On the one hand, renewable energy holds the potential to emerge as our ultimate solution if harnessed effectively. Solar, wind, tidal energy, and other renewable sources stand out prominently, offering far better alternatives to fossil-based fuels. The discernible advantage lies in the marked differences in environmental friendliness and the safeguarding that renewable energy can provide, unlike fossil-based fuels which vent out toxic gasses, which if breathed on a regular basis, could lead to respiratory diseases and more. Moreover, these gases are the primary contributors to the ozone layer’s depletion and global warming. Therefore, renewable energy not only benefits our well-being but also contributes to the health of our planet. Australia is one of the finest examples, embracing wind and solar energy projects, contributing significantly to its electricity generation and concurrently cutting down on air pollution.
On the other hand, renewable energy faces challenges related to reliability, as natural sources like sunlight and wind may not be consistently available. Factors such as precipitation and daylight hours impact successful energy harnessing. For instance, continual rainy or cloudy weather makes electricity production from solar energy close to impossible, and storing it can be costly, highlighting the practical challenges of relying solely on renewables. On the other hand, fossil fuels, like coal, despite environmental concerns, provide a reliable energy source that remains consistently available until fully depleted, exemplifying centuries-long dependence of humanity on such resources.
To conclude, while renewable energy could be the finest alternative to fossil fuel and can be better for our environment and health, it still lacks in the areas of consistency in production, and we cannot yet rely on it solely. However, as technology is evolving, it is possible that the future will offer better alternatives and solutions where we can produce energy without compromise.
