Let's discuss the energy sources India relies on. What are some conventional energy sources that come to mind?
I think of thermal power plants and hydroelectric projects.
Correct! Thermal power plants emit significant amounts of carbon dioxide, contributing to greenhouse gases. Can anyone tell me about the environmental effects of hydroelectric projects?
They can flood forests and disrupt local ecosystems.
Exactly! This leads us to a critical issue: the need for non-conventional energy sources. Remember the acronym **SWT** for solutions: Solar, Wind, and Traditional knowledge!
How do these non-conventional sources help our environment?
Great question! They produce less pollution and often utilize renewable resources, helping us move towards sustainable development.
So, by using these sources, we can reduce our carbon footprint?
Yes! Let's summarize: India’s reliance on conventional energy impacts the environment, highlighting the need for SWT solutions.

Now let's explore some non-conventional energy sources. Who can name a few?
Solar energy and wind energy!
Exactly! Solar energy can be converted into electricity using photovoltaic cells. What advantages does solar energy have?
It's abundant and doesn’t pollute!
Correct! Wind turbines also provide clean energy. What about biogas; how does it work?
It’s produced from waste, which helps in managing waste too.
Right! And they can also provide a good organic fertilizer as a byproduct. Good job, everyone! Remember, using non-conventional sources can profoundly impact our future.

Quick Overview
Standard
The section emphasizes the growing dependence on thermal and hydro power plants in India, highlighting the environmental impacts of these sources. It advocates for the adoption of non-conventional sources of energy, such as solar, wind, and biogas, which provide cleaner alternatives and reduce environmental degradation.
Detailed
Use of Non-conventional Sources of Energy
India heavily relies on thermal and hydro power plants, which have significant environmental adverse effects, such as carbon dioxide emissions and ecological disruption due to dam constructions and resource extraction. The urgency of transitioning to non-conventional energy sources is underscored due to these environmental challenges. Non-conventional energy sources include wind power, utilizing abundant solar energy via photovoltaic cells, biogas from waste materials, and mini-hydel plants that harness energy from small streams without altering land patterns. These methods not only produce cleaner energy but also align with sustainable development by protecting natural ecosystems and utilizing locally available resources, diminishing dependency on fossil fuels. The section also touches on how traditional practices and knowledge can contribute to these energy solutions, underlining the importance of integrating such systems into modern energy policies.
