Tropical peatlands, particularly in Southeast Asia, are significant sources of greenhouse gas emissions, acting as net emitters rather than carbon sinks as previously believed. Research by Hokkaido University (2026) revealed that even intact, waterlogged peat forests release more carbon dioxide and methane than they absorb. Human drainage for agriculture increases these emissions more than sixfold.

 Tropical peatlands, particularly in Southeast Asia, are significant sources of greenhouse gas emissions, acting as net emitters rather than carbon sinks as previously believed. Research by Hokkaido University (2026) revealed that even intact, waterlogged peat forests release more carbon dioxide and methane than they absorb. Human drainage for agriculture increases these emissions more than sixfold. 
Key Findings on Tropical Peatland Emissions:-
Net Emitters: -
Intact tropical peat swamp forests in Sumatra, Borneo, and the Malay Peninsula were found to be net sources of greenhouse gases, challenging their long-term classification as carbon sinks.
Impact of Drainage:-
 Draining these forests for agriculture lowers water tables and accelerates peat decomposition, resulting in nearly three times more greenhouse gas emissions than natural states.
Climate Impact: -
Total emissions from these regions are estimated to be equivalent to about 30% of Japan’s annual greenhouse gas output.
Extreme Events:-
 Droughts linked to El Niño events further increase annual emissions by approximately 16%.
Significance: -
While covering only about 3% of land, tropical peatlands store immense amounts of carbon; their degradation makes them a major, growing source of global emissions. 
The research suggests that proper management, such as maintaining high water tables, is critical to reducing these emissions.

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.
