There is a growing need to harness non-conventional energy sources due to the depletion of traditional fossil fuels and the increasing environmental impact of energy production. Specifically, the limited availability of fossil fuels and the significant environmental consequences of using them necessitate the development of renewable alternatives.
Here’s a more detailed explanation:
1. Depletion of Fossil Fuels: Conventional energy sources like coal, oil, and natural gas are non-renewable and finite resources. As global energy demand continues to rise, the depletion of these fuels poses a significant long-term challenge. Non-conventional sources like solar, wind, and geothermal energy, on the other hand, are renewable and readily available, providing a sustainable alternative.
2. Environmental Impact of Fossil Fuels: The burning of fossil fuels releases greenhouse gases, contributing to climate change and air pollution. This environmental impact is a major concern, prompting the search for cleaner and more sustainable energy sources. Non-conventional sources of energy, such as solar, wind, and hydro, have a much lower environmental impact and can help mitigate climate change.
In essence, the need to harness non-conventional sources of energy arises from the need to ensure a sustainable energy supply and reduce the environmental impact of energy production.
