The Role of Solar Energy in Combating Climate Change Globally

Introduction:
Climate change is one of the most severe challenges facing humanity in our modern day, largely as a result of the high levels of greenhouse gases (GHGs) being released into the atmosphere by the combustion of fossil fuels for energy. As global warming takes hold of the world and action is taken to address its effects, the move to cleaner, more renewable energy sources has become a priority. Solar power is one of the most hopeful solutions among them. Homeowners, businesses, and governments are all turning to solar power systems– now more than ever our goal is not just to help control the rising cost of energy, but to help create a greener, less carbon intensive planet with a more sustainable future.
Although solar power is often touted as a zero-emission solution, it’s important to know the good and bad of its environmental impacts. This report examines the role of solar photovoltaics (“PV”) in reducing climate-altering greenhouse gas emissions and the degree to which the technology could affect global temperature, as well as the full environmental costs of solar PV.
Emission of Greenhouse Gases by the Electric Power Sector:
The electric power sector is one of the largest producers of GHG emissions in the world. India is particularly crucial, and the situation there is particularly dire. In December 2020, coal-fired power plants were emitting 1.1 GtCO₂ annually, or around 2.5% of global emissions. These power plants are themselves responsible for one-third of India’s total GHG emissions and half of all carbon emissions from fuel-burning activities in India.
A large number of these facilities do not have even rudimentary pollution control equipment. Uncontrolled use of coal, with no provisions for carbon capture and storage systems, has not only further India’s carbon footprint, but also has worsened its already bad air pollution.
The water waste is not the case with solar, a renewable source. Moving away from coal and fossil fuels toward solar power is necessary to curb emissions at home and abroad.
Solar panels generate low-carbon electricity:
The sun is considered one of the cleanest and most renewable sources of energy that we have-besides, of course, being free. Solar photovoltaic (PV) systems do not directly generate carbon during their operation, unlike fossil fuels. Solar panels, merely by collecting light from the sun and turning it into electricity, provide an emission-free option once put into place.
One kilowatt of solar generation offsets one kilowatt of electricity that otherwise would come from a coal or gas plant. This directly counteracts CO₂ emissions, the main driver behind man-made climate change. Even on a small scale, solar on homes or businesses makes a substantial difference for climate. One standard rooftop solar system, for instance, can trim carbon emissions by several tonnes a year.
And unlike other forms of power, like coal or oil, sun is not a resource that needs to be burned or mined, which keeps the environment clean. Sun is simply limitless and it is free as well as non-polluting, so an efficient solution for a greener and sustainable planet.
Solar Farm Assembly and Transport: A Tiny Carbon Footprint:
Though solar panels during operation are nearly emission-free, it’s worth mentioning that their manufacturing, transportation and installation all produce emissions. The manufacturing of solar PV modules is energy intensive and frequently uses non-renewable energy, that contributes to its initial carbon footprint.
For the first several years of a solar panel’s life, every unit of electricity it produces is effectively used to “pay back” this carbon debt. On average solar panels in early operation emit about 50 grams of CO₂ per kilowatt-hour (kWh). By comparison, coal-fired plants produce more than 1000 grams of CO₂ per kWh. This would still make solar power 20 times cleaner by implication, even before we reach full carbon neutrality.
Thankfully, most modern panels outlast people—usually 20 read more to 30 years. After 2-3 years, they become carbon neutral, and the remaining years of operation produce clean, emission-free energy.
Water use for solar power:
Water is also a critical issue, particularly in a country like India where water and electricity are both highly sought after. Coal power plants require KWh of water to produce steam and for cooling, whereas for a solar PV asks 22lakes of water.
But solar power isn’t completely water-free. Water is required:
In the production of the solar modules (80% of the water consumption in the PV value chain).
To clean solar panels to keep them efficient — especially in dusty or dry regions.
Wet cleaning of solar panels requires 7,000 to 20,000 liters per megawatt per wash, according to the Council on Energy, Environment and Water (CEEW). In areas without water distribution pipelines, local groundwater could be employed, possibly overburdening local water resources.
Thus, although solar energy decreases pollutants like air and carbon pollution, smart water management is needed for making solar green in most cases. The development of dry-cleaning technologies or robot cleaning systems may contribute to decrease this water footprint.
Wider Environmental and Economic Benefits:
Apart from emissions reduction and resource conservation, solar energy utilization comes with various environmental and socio-economic benefits:
Better air: Solar systems decrease reliance on power plants that produce dirty power, so fewer pollutants are released in the air, such as SO₂, NOₓ, and CO₂.
Decreased dependence on fossil fuel: Every megawatt of solar installed equals a corresponding amount of electricity not generated by fossil fuel, cutting back on the world’s use of nonrenewable resources to generate electricity.
Independence from imported fuels: Because it generates power where it is used, solar helps cut dependence on imported fuel.
Green jobs: There are jobs in the solar industry from manufacturing to installing and maintaining panels.
Conclusion:
Solar power is a central solution to climate change, providing a clean, renewable, and increasingly cost-effective source of electricity that reduces the need to burn coal, oil and natural gas. Not perfect for the environment, but grossly beneficial compared to the vast majority of the energy production by-products, including lower emissions than the coal foundation, lower water consumption relative to coal, and in the long term viable.
Its carbon and water footprints will continue to shrink as technology progresses and the solar industry grows up. By scaling up solar power, countries like India can achieve meaningful progress toward their net-zero aspirations, improving the quality of air and water and developing a resilient, low-carbon economy.
The shift from any energy source to solar is not merely a matter of personal choice — it is a matter of climate legacy. The quicker we accept, the better chance we have of preserving a bearable future for generations to come.
