European Commission: Natural gas can be part of green transition

The EU today confirmed natural gas-fired power and heat generation facilities can qualify for Covid-recovery spending as long as they fulfil a maximum emission target or are accompanied by credible member-state plans to ramp up renewables usage.

Getting serious about soiling

Scientists in the United States and India are investigating the impacts of soiling on PV installations in the Indian state of Gujarat. The group, which found that soiling losses for the state could add up to $12 million per year, is looking for low-cost ways to monitor and reduce the impacts of soiling on modules in the field.

Cleaning the air is like ‘moving a solar panel from Toronto to Houston’

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.

Covid-19 weekly round-up: Q Cells has given a timely boost to EU solar as the clamor grows for a green recovery

Plus, there was plenty of hope in predictions made by Norwegian institute DNV GL but U.S. households are facing hefty energy bills just as data from Delhi showed the link between industrial shutdowns and cleaner skies.

Lockdown and PV’s positive feedback loop

Scientists measuring air pollutants and PV performance in Delhi have found the lockdown conditions imposed in the Indian capital since late March have brought about a significant reduction in air pollution which has led to an 8% increase in solar irradiation reaching rooftop arrays.

Substantial solar gains to be had from clean air – study

Eliminating emissions from the air would increase solar radiation by an average of 11%, allowing solar cells to generate one tenth more electricity claim researchers in a new study. Focusing on China, they say an additional 85-158 TWh of electricity could be generated annually in 2040, if the air was clean.

EBRD urges Western Balkans to replace 18 GW of coal with renewables

The EBRD has released a brief urging Western Balkan countries to both replace their aging lignite coal generation capacity with renewables, and to rethink their 18 GW plans for new coal capacity. While the region offers favorable conditions for various types of renewable generation, it has been slow on the uptake to date.

Solar performance polluted by urban haze

Research conducted over several years by scientists at the Massachusetts Institute of Technology (MIT) demonstrates that air pollution in cities can put a dampener on the performance of PV panels which, if not taken into account, can threaten a project’s viability.
