Renewable energy is seen as the future of sustainable power, helping solve environmental and economic problems linked to traditional energy sources. Despite its growing use, myths still affect public views. This article aims to clear up these misunderstandings with facts, focusing on India.
Myth 1: Renewable Energy is Too Expensive
Many believe R.E. is too expensive, but while initial costs for solar panels and wind turbines are high, long-term savings often justify the investment.
Reality: The International Renewable Energy Agency (IRENA) states that solar photovoltaic (PV) system costs have plummeted by over 80% in the last decade. In India, the price of solar PV has dropped from ₹90 per watt in 2010 to about ₹20 per watt in 2023, making it much more affordable.
Example: A 5 kW solar PV system, costing approximately ₹100,000, generates around 20 kWh daily. With the average electricity rate at ₹8 per kWh, this system can save ₹4,800 per month, paying for itself in less than 2.5 years.
Myth 2: R.E. Sources Are Unreliable
Some claim solar and wind energy are too weather-dependent, but technological advances have greatly improved their reliability.
Reality: The Energy Storage Association reports that contemporary battery storage can hold energy for up to 12 hours, addressing intermittency concerns. In India, investments like the 100 MW grid-scale battery system in Tamil Nadu are improving the reliability of renewable energy.
Example: Solar panels produce power even on cloudy days, with surplus energy stored for later use.
Myth 3: Renewable Energy Can't Meet Large-Scale Energy Needs
There is a belief that renewable energy cannot meet the demands of large cities or industries. However, this myth is being disproved as renewable energy infrastructure expands.
Reality: India is making significant progress, with the Ministry of New and Renewable Energy (MNRE) reporting that 19.6% of the country’s electricity came from renewable sources in 2023, thanks to major wind farms and solar parks.
Example: The Kutch Solar Park in Gujarat, one of the largest globally, has a 2.5 GW capacity, enough to power over 2.5 million homes. Tamil Nadu’s wind farms, with over 8 GW capacity, show that R.E. can meet large-scale demands.
Myth 4: Renewable Energy is Harmful to the Environment
Some believe that making and disposing of R.E. technologies, like solar panels and wind turbines, can harm the environment. But even with some impact, R.E. is still much cleaner than fossil fuels.
Reality: The National Renewable Energy Laboratory (NREL) states that solar panels have a lifecycle carbon footprint of about 20 grams of CO2 per kWh, compared to 900 grams per kWh for coal.
Example: A 5 kW solar PV system can offset around 15 tons of CO2 over its 25-year lifespan, reducing environmental impact despite the resources used in its production.
Myth 5: Renewable Energy Technologies Require Too Much Land
A misconception exists that R.E. installations need excessive land. While large-scale setups require space, they can be integrated with other land uses.
Reality: Solar farms can be installed on rooftops or non-agricultural land, such as deserts. Wind turbines can be placed offshore or on farmland, allowing dual land use.
Example: The Charanka Solar Park in Gujarat occupies 2,000 hectares in a desert region unsuitable for agriculture. Wind farms in Maharashtra and Karnataka are often on agricultural lands, with turbines taking up only a small portion, allowing farming to continue.
Conclusion
R.E. is often misunderstood, and myths can slow down progress toward sustainability. By providing clear and accurate information, we can understand its true potential. As India invests in these technologies, it's important to see their ability to offer reliable, affordable, and eco-friendly power.
