Pollution

An international research team has measured the reduction of air pollution due to the Covid-19 shutdown and its impact on solar radiation levels. They found that solar radiation in Delhi, one of the world’s most polluted cities, was around 8.3% higher in late March, when the Indian government implemented lockdown measures.

The mature renewable energies are the most efficient power resources to slow down global warming and reduce human health impacts, according to a new study published in Nature Communications. The authors claim renewable energy generation capacity is also the best way to reduce land use, toxicity and drinking water depletion.

The threat of India’s government imposing anti-dumping duties (ADD) against solar cells and modules from China, Taiwan and Malaysia is very real, and runs counter to its own ambitions of hitting 100 GW of solar by 2022. Or does it? Could duties help to boost India’s solar industry in other ways? And does the ongoing political uncertainty create opportunity or trepidation for industry?

Accumulation of airborne particles on solar panels may cut energy output by more than 25% in some parts of the world, shows a new study carried out by researchers of Duke University, in cooperation with colleagues at the Indian Institute of Technology-Gandhinagar and the University of Wisconsin at Madison.
