Aiming to complement NREL’s Best Research-Cell Efficiency Chart and the Solar cells efficiency tables by Martin Green et al., which list the absolute best performing certified efficiencies for each major photovoltaic (PV) technology, emerging PV reports provides an alternative reference. We summarize the best results in the PV research, as published in academic journals (certified and uncertified) and with respect to the Shockley-Queisser efficiency limit, encouraging the reproducibility of the results. Unlike the established overviews, our new approach also deals with the best flexible, transparent/semitransparent and long-term photostable PV devices. In all cases, we also suggest protocols for best practices in characterization and reporting of emerging PV device performance.
3 December 2020, Singapore – The Global Wind Energy Council (GWEC) welcomes the recent decision by the Vietnamese government to approve an extension of the Feed-in Tariff (FIT) scheme for wind power in the country. However, the proposed dramatic reduction to the FIT risks seriously damaging the growth of Vietnam’s promising wind power sector, slowing down investment and the creation of new jobs and making it harder for Vietnam to meet growing energy demand.

The geopolitics of the Mekong river continue to evolve, with key announcements from China, Thailand and the Mekong River Commission.
Editorial
Recent weeks have seen new developments in the ongoing tension over the Mekong river and its waters, as the river basin faces ecological crises and its waters play an ever-larger role in geopolitics.
Thailand has announced that it is reconsidering its decision to purchase power from the planned Sanakham Dam, a large hydropower project on the mainstream of the Mekong in Laos. Tiếp tục đọc “Geopolitics plays out on the Mekong with doubts on dams and promises of cooperation”
Prior to the devastating impacts of COVID-19, Southeast Asia was becoming an economic powerhouse. Manufacturing, industry and services expanded across the region in recent decades. Energy demand also grew an average of 6% per year, one of the fastest growth rates in the world. But despite the global decline in renewable energy prices, Southeast Asian countries have largely embraced fossil fuels to meet their growing energy needs.

This paper highlights how civil society organizations can play critical roles in establishing transparent and accountable climate finance systems that put communities at the center of decision-making. It draws from the Adaptation Finance Accountability Initiative’s experiences in Ethiopia and Uganda as well as lessons learned from similar efforts in Bangladesh, Kenya, and the Philippines. It offers valuable information to help civil society organizations build their engagement and capacity on climate adaptation finance.
Những cuộc đào bới, triệt hạ cây rừng bắt đầu từ nương rẫy, dần tấn công cả vào rừng phòng hộ. Rừng bị tàn sát khiến lũ lụt gia tăng. Trong khi đó, các cơ quan chức năng lại kêu khó vì pháp luật còn nhiều kẽ hở.

Former U.S. Vice President Joseph R. Biden and his running mate Kamala Harris are widely recognized as having won the 2020 U.S. presidential election, with a majority in the Electoral College and a resounding majority in the popular vote. The Democratic Party has retained control of the U.S. House of Representatives, while the results for the U.S. Senate are very close and the outcome is undetermined at this time. In this WRI Commentary, WRI U.S. Director Dan Lashof suggests a 10-point plan for the new administration.
President-elect Biden will be sworn into office in the midst of four deeply intertwined crises: the health crisis, the economic crisis, the racial injustice crisis and the climate crisis. He has promised to build back better by taking bold action on all four simultaneously, including making unprecedented investments in health care, infrastructure and clean energy.

For the first time since records began, the main nursery of Arctic sea ice in Siberia has yet to start freezing in late October.
The delayed annual freeze in the Laptev Sea has been caused by freakishly protracted warmth in northern Russia and the intrusion of Atlantic waters, say climate scientists who warn of possible knock-on effects across the polar region.
Ocean temperatures in the area recently climbed to more than 5C above average, following a record breaking heatwave and the unusually early decline of last winter’s sea ice.
The trapped heat takes a long time to dissipate into the atmosphere, even at this time of the year when the sun creeps above the horizon for little more than an hour or two each day.
Graphs of sea-ice extent in the Laptev Sea, which usually show a healthy seasonal pulse, appear to have flat-lined. As a result, there is a record amount of open sea in the Arctic.
“The lack of freeze-up so far this fall is unprecedented in the Siberian Arctic region,” said Zachary Labe, a postdoctoral researcher at Colorado State University. He says this is in line with the expected impact of human-driven climate change.
“2020 is another year that is consistent with a rapidly changing Arctic. Without a systematic reduction in greenhouse gases, the likelihood of our first ‘ice-free’ summer will continue to increase by the mid-21st century,’ he wrote in an email to the Guardian.

The world is not on track to avoid the catastrophic impacts of climate change. With 2030 just a decade away, and governments are under pressure to speed up the clean energy transition.
The good news is that: a) the technologies and the capital are available to accelerate the green energy transition, and b) the private sector is ready to invest billions of green dollars into decarbonization and clean energy.
But how can governments provide the institutional and regulatory frameworks that make it attractive for private companies and investors to invest in and deploy the needed solutions and technologies to accelerate the clean energy transition?

A recent Harvard analysis led by Professor Francesca Dominici along with Doctoral student Xiao Wu and Assistant Professor Rachel Nethery is the first nationwide study to show a statistical link between COVID-19 deaths and other diseases associated with long-term exposure to fine particulate matter. The paper has been submitted for peer review and publication in the New England Journal of Medicine.
