<p><strong>The future is solar.</p></strong>
<p>As India continues its rapid economic growth, energy demand is skyrocketing. Traditionally, this demand has been met through fossil fuels such as coal, oil, and gas. However, there is increasing awareness about the environmental impacts of fossil fuels, such as air and water pollution. Solar energy offers a clean, renewable alternative that can help India meet its energy needs in an eco-friendly manner.</p>
<p>The sun has always been vital to life on earth, powering biological processes and food chains. As a source of renewable energy, solar power builds on the sun’s role as a sustainable energizer of natural systems. Just like plants harness the sun’s energy through photosynthesis to create biomass and nutrients, human-made solar photovoltaic panels and concentrated solar thermal plants also utilize sunshine to generate green electricity and heat. By tapping into the original nuclear reactor skyrocketing 150 million kilometers away, solar energy systems provide clean fuel for industries and households to operate in an eco-friendly manner. Whether used directly, stored for later use, or integrated with other renewables like wind and hydro, solar energy is poised to displace fossil fuels as we transition our economies toward a low-carbon future powered by this ultimate energy source.</p>
<p>In this blog, we will explore the environmental benefits of solar power and why it needs to play a bigger role in India’s energy mix as we power tomorrow.</p>
<p><strong>The Promise of Solar Energy</p></strong>
<p>Solar energy has huge potential in a tropical country like India. We receive abundant sunshine for major parts of the year, with average solar insolation ranging from 4–7 kWh/sq.m across different states. In fact, just a small patch of land in Rajasthan receives energy from the sun equivalent to India’s entire fossil fuel reserves!</p>
<p>However, despite this potential, solar energy contributes less than 4% to India’s electricity generation currently. But the scenario is set to change drastically. Thanks to rapidly decreasing costs, increasing efficiency, and supportive government policies, India has set an ambitious target of achieving 175 GW of renewable energy, of which 100 GW is slated to come from solar.</p>
<p>Major investments are already flowing into the Indian solar sector from both public and private players. Employment opportunities in solar are also opening up across the value chain, from R&D to equipment manufacturing to project construction and O&M roles. Thus, the solar revolution in India is set to have ripple effects across economic and social sectors.</p>
<p><strong>Environmental Impact</p></strong>
<p>What are some of the key environmental benefits that greater adoption of solar energy will usher in?</p>
<p>1. Mitigating climate change: Solar PV and CSP plants emit no greenhouse gases or air pollutants during operation, helping tackle global warming and climate change issues.</p>
<p>2. Preventing pollution: Increased solar energy will displace fossil fuel plants, resulting in lower emissions of harmful pollutants like particulate matter (PM), nitrous oxides (NOx), mercury, and more. This leads to improved air, water, and soil quality.<p>
<p>3. Saving water: Solar PV and CSP plants utilize minimum water for operations. On the other hand, thermal power plants consume vast amounts of water for cooling purposes. Higher solar capacity will alleviate India’s water scarcity challenges.<p>
<p>4. Utilizing wastelands: Large solar power plants can utilize wastelands and thus prevent their degradation. This preserves biodiversity and enhances land-use efficiency.</p>
<p><strong>Sustainability Concerns</p></strong>
<p>However, there are also some concerns around solar farms regarding land usage, lifecycle emissions, and resource extraction methods. These need to be responsibly addressed. For example, utility-scale solar farms should avoid using farmland and forestland, given India’s constraints. Instead, barren lands should be preferred. Concepts like agri-solar, which deploys solar around agricultural landscapes, can also be explored.</p>
<p>There are also some emissions during upstream module manufacturing and end-of-life disposal. These can be minimized by adopting cleaner production processes, using recyclable materials, and enabling panel recycling. Leading Indian solar manufacturers like Waaree are proactively working on these aspects.</p>
<p>Responsible and regulated mining practices should be followed for resource extraction to obtain solar components like silicon, glass, aluminum, etc. Reuse and recycling protocols for panels at the end of their lives also need to be institutionalized.</p>
<p><strong>The Way Forward</p></strong>
<p>Thus, solar energy has huge potential to provide clean, green energy security to India’s development story. While rapidly scaling capacity, sustainability principles around land use, lifecycle impacts, and resource cycles must also be focused on. Policy frameworks should drive the adoption of solar energy in tandem with energy efficiency and smart energy storage solutions to build robust renewable energy systems.</p>
<p>The sun provides each day with enough energy to meet our power requirements for an entire year. It’s time to harness this limitless solar resource through urgent investments and supportive policies to power tomorrow in a manner that is clean, green, and sustainable.</p>
