Main Advantages of Renewable Energy
Renewable energy offers three major benefits for India: lower fuel costs, reduced emissions and greater energy security.
- Lower running costs: Solar and wind power do not require fuel purchases. Once a plant is built, its operating costs are less exposed to changes in fuel prices.
- Cleaner air: Renewable energy can reduce emissions when it replaces fossil-fuel-based electricity. In FY2026, solar accounted for 9.46% and wind for 5.77% of India’s electricity generation, while thermal power accounted for 70.73%.
- Greater energy security: Solar and wind use resources available within India, reducing the need to import fuel for the electricity they generate. Non-fossil sources accounted for 55.11% of India’s installed power capacity as of September 2026.
Disadvantages of Renewable Energy and Ways to Address Them
Renewable energy also has practical limitations, from the cost of building new plants to the challenge of supplying electricity when the sun isn’t shining or the wind isn’t blowing. Here are the main disadvantages of renewable energy and the disadvantages of green energy, sometimes called green energy, and the measures that can help address them.
1. High Initial Investment
Solar and wind projects require substantial investment in equipment, land and grid connections before they start generating revenue. Transmission infrastructure also needs major investment. Its estimated capital expenditure for 2026–27 to 2031–32 is ₹5–6 trillion.
How to address it: Power purchase agreements (PPAs) and open-access arrangements allow businesses to buy renewable electricity from developers without having to fund and build their own power plants.
2. Renewable Power Supply Can Vary
Solar panels generate electricity during daylight hours, while wind power depends on wind conditions. This means renewable output can change throughout the day and across seasons. Around 470 GWh of renewable electricity from inter-state projects went unused in the first quarter of 2026, partly because of transmission constraints.
How to address it: Combining solar and wind can help balance changes in generation because the two sources may produce more power at different times. Businesses can also contract for a firm electricity supply instead of relying only on the output of an individual renewable plant.
3. Energy Storage Adds to Costs
Batteries can store surplus renewable electricity for use when generation falls, but storage systems require additional investment. As of 30 September 2026, India had commissioned 14,543.20 MWh of battery energy storage capacity. The National Electricity Plan estimates a requirement of 411.4 GWh of battery storage by 2031–32.
How to address it: Battery energy storage systems (BESS) can help manage short-term changes in supply. Pumped storage hydropower can store energy for longer periods by pumping water to a higher reservoir and releasing it to generate electricity when needed.
4. Large Projects Require Significant Land
Utility-scale solar and wind projects can require large areas of land. For example, the Khavda renewable energy park in Kutch covers 72,400 hectares and has a planned capacity of 30 GW.
How to address it: Developers can consider suitable wasteland, floating solar installations on water bodies and wind farms where farming or grazing can continue around the turbines.
5. Renewable Resources Vary by Location
Not every state has the same potential for solar, wind or hydropower. Wind resources, for instance, are concentrated in a limited number of states. Eight states account for 676.55 GW of India’s estimated 695.50 GW of wind potential at a height of 120 meters.
How to address it: Inter-state transmission networks can carry electricity from resource-rich regions to areas with higher demand. Hybrid projects can also combine the renewable sources best suited to a particular location.
6. The Electricity Grid Needs Upgrades
Renewable energy projects are spread across different locations, so the grid must carry electricity from these plants to homes and businesses. India had around 503,661 circuit kilometers of transmission lines against a target of 648,190 circuit kilometers for FY2031–32. Annual additions averaged 13,000 circuit kilometers against the 16,230 required.
How to address it: Green energy corridors, improved transmission-line monitoring and early planning for grid connectivity can help move renewable electricity more efficiently.
7. Manufacturing and Disposal Have Environmental Costs
Although renewable energy generates electricity without burning fuel, manufacturing equipment requires materials and energy. Solar panels also need proper handling at the end of their useful life. India is projected to generate around 600,000 tonnes of solar panel waste by 2030.
How to address it: Recycling and responsible disposal can help recover useful materials from old panels. Solar panels are covered under the E-Waste Management Rules, 2022. A producer responsibility portal is operational, and a ₹1,500 crore recycling incentive has been announced under the National Critical Mineral Mission.
8. Wildlife Impact and Project Delays
Wind turbines can affect birds and other wildlife if projects are placed in sensitive areas. Renewable energy projects can also face delays because of land, transmission and approval requirements. By March 2026, only 12% of transmission projects commissioned under competitive bidding had met their scheduled timelines, with the median delay exceeding 10 months.
How to address it: Careful site selection can reduce the impact on wildlife. Measures such as radar-based turbine shutdowns during bird migration, along with coordinated approvals, can also help reduce project risks and delays.
Advantages and Disadvantages of Different Renewable Energy Sources
Each renewable energy source has its own strengths and limitations. The table below compares the main options and explains why some projects combine multiple sources.
| Energy source | Main advantages | Main disadvantages |
|---|---|---|
| Solar energy | Can be installed at different scales and has no moving parts in standard solar PV panels | Generates electricity only when sunlight is available |
| Wind energy | Can generate power at night and during seasons when wind conditions are favorable | Output varies with wind speed and suitable sites are location-dependent |
| Hydropower | Reservoir-based projects can provide controllable power and operate for many years | Output can depend on rainfall, and large projects may displace communities |
| Biomass energy | Uses agricultural and other organic waste and can generate power when needed if fuel is available | Requires a reliable supply of suitable fuel |
| Geothermal energy | Can provide a steady supply of power regardless of daily weather conditions | Suitable resources are available in relatively few locations |
Combining sources such as solar and wind, along with suitable storage, can help address these limitations and improve the reliability of renewable electricity.
Renewable Energy vs Non-Renewable Energy: Advantages and Disadvantages
The main difference between renewable and non-renewable energy is how quickly their sources are replenished. Renewable sources such as sunlight and wind replenish naturally, while fossil fuels take millions of years to form.
The table below summarises the main advantages and disadvantages of renewable energy and non-renewable energy.
| Factor | Renewable energy | Non-renewable energy |
|---|---|---|
| Fuel supply | Uses naturally replenished resources | Depends on finite resources such as coal, oil and natural gas |
| Fuel costs | Solar and wind do not require purchased fuel | Fuel purchases expose operators to price changes |
| Emissions | Generates electricity without combustion at the point of generation | Burning fossil fuels releases greenhouse gases and other pollutants |
| Power availability | Solar and wind output varies with weather and time of day | Thermal power plants can generate electricity on demand when fuel and plant capacity are available |
| Infrastructure | Requires suitable generation sites, storage and grid connections | Benefits from existing plants and fuel supply networks |
| Energy security | Can reduce reliance on imported fuels | May depend on domestic reserves or imported fuel |
India has an estimated 400.72 billion tonnes of coal resources, according to the Ministry of Coal. Coal’s availability and existing power infrastructure help explain why thermal sources still accounted for 70.73% of India’s electricity generation in FY2026.
Renewable energy can reduce fuel costs and emissions, but reliable supply also depends on storage, transmission and careful project planning. Non-renewable sources can provide power on demand, but they rely on finite fuels and produce emissions when burned.
Conclusion
Renewable energy can reduce fuel costs, lower emissions and strengthen India’s energy security. However, high initial investment, changing generation and gaps in storage and transmission remain important challenges. These limitations can be addressed through better grid infrastructure, energy storage and projects that combine different renewable sources.
