☀️🌬️ Does India have enough freely accessible observational data to support its renewable energy transition?
The answer is yes—but not yet at the #density needed to scale reliable renewable-energy services to the community level.
In our new Perspective article (IOP Publishing Environment and Energy), we quantitatively assess the freely accessible observational networks relevant to renewable energy in India and compare them with global renewable-energy leaders that have comparable resource potential but substantially denser monitoring networks.
The message is simple: renewable-energy potential alone is not enough. A successful transition also needs a strong observational backbone.
Better observations → better resource assessment → better forecasting → better decisions → more resilient renewable-energy services.

How can we make urban energy transitions more equitable?
As cities accelerate their transition toward clean energy, an important question remains:
How do the spatial patterns of socio-demographic, socio-economic, and urban morphological characteristics shape energy transition outcomes?
Rather than focusing only on renewable energy potential, we develop a spatially explicit framework that examines how different determinants interact to influence key urban energy metrics, including:
☀️🏠 Rooftop PV potential
⚡🏢 Electricity Consumption
🏠🔋 Energy Adequacy
🧾💸 Energy Burden

🌞 How does surface ozone (O₃) vary across India, and what roles do its precursors (VOCs, NOₓ, CO, HCHO) play?
We investigated the spatio-temporal variability of surface O₃ across India, using widely accepted precursor indicators like the HCHO/NOₓ ratio to classify O₃ formation regimes. We also explored the NO/NO₂ ratio to gain insights into the delicate balance between O₃ production and destruction. 🌤️
🔍 Key Findings:
1️⃣ Positive O₃ trends were observed across most of India — except in central Indo-Gangetic Plain (IGP).
2️⃣ VOC-limited regimes dominate, meaning O₃ formation is more sensitive to VOCs than NOₓ.
3️⃣ In the IGP, increasing NO/NO₂ ratios suggest reduced surface O₃ due to enhanced titration, despite high precursor loads.
📊 These results help decode the complex interplay of emissions and chemistry driving air quality over India — crucial for crafting effective mitigation strategies.
