Delhiites face persistent, year-round air quality challenges with no immediate timeline for consistently meeting national standards. While 2025 saw a record 79 days with "Good" or "Satisfactory" air, hazardous conditions continue in winter. Long-term efforts like the National Clean Air Programme target a 40% reduction in particulate matter by 2026, but reaching consistent compliance remains a long-term goal.

Delhiites face persistent, year-round air quality challenges with no immediate timeline for consistently meeting national standards. While 2025 saw a record 79 days with "Good" or "Satisfactory" air, hazardous conditions continue in winter. Long-term efforts like the National Clean Air Programme target a 40% reduction in particulate matter by 2026, but reaching consistent compliance remains a long-term goal. 

Key Factors and Future Outlook:
Current Status: -
In 2025, Delhi recorded zero "good" air quality days, with the air quality often falling into poor, severe, or hazardous categories, especially in winter.
Winter Crisis: -
Air quality drastically worsens between October and February due to stubble burning, low wind speeds, and temperature inversion.
Improvement Efforts: -
Ongoing measures include stricter emission controls for industries, banning older vehicles, and deploying water sprinklers, though these have not yet brought permanent, year-round clean air.
Long-Term View: -
Officials have suggested that achieving clean air in a city like Delhi could take several decades, similar to the experience of other global cities. 
Therefore, while incremental improvements are occurring, meeting the National Air Quality Standards (NAAQS) consistently throughout the year is expected to take many years, with 2026 acting as a key intermediate target for emission reductions.

   Water sprinklers have been deployed across Delhi. The real time and old data of air quality is available and data was missing for a maximum of five minutes.

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

State-wise carbon emissions in India show a concentration in western and southern states, with byd as major emitters, particularly from the manufacturing and energy sectors. The highest total CO2 emissions have been linked to states like Maharashtra, Andhra Pradesh, Uttar Pradesh, Gujarat, Tamil Nadu, and West Bengal, though the specific ranking can vary depending on the data year and the specific pollutants included.
