1. Mark Hudema’s tweet on flexible solar panels developed by researchers in Australia

Mark Hudema, director of communications at environmental non-profit organisation Canopy Planet, tweeted a video on flexible solar panels developed by the University of Newcastle in Australia. The solar panels can be printed like newspapers onto thin surfaces. The panels can be used for mobile applications and mounted on rooftops where traditional solar panels cannot be installed.

The solar panels were developed by the researchers to minimise energy prices and carbon emissions. The production cost of the panels is less than $0.93 per sq.ft and they have a low maintenance cost. The panels can be easily fixed and repaired by simply replacing a broken unit with a new one, according to the video.

2. Mark Z. Jacobson’s tweet on Paraguay disconnecting its last thermal power plant

Mark Z. Jacobson, professor of civil and environmental engineering at Stanford University, shared an article on Paraguay disconnecting its last thermal power plant becoming the first country with 100% clean and renewable electricity. The government completed the electrification works to the remote town of Baha Negra from its hydroelectric power plants marking the transition of the country towards 100% renewable energy.

The electrification works were funded by Aspen Network of Development Entrepreneurs (ANDE), a network of organisations that support entrepreneurship. They will help in reducing the country’s reliance on fossil fuels to generate electricity and improve the reliability, safety, and quality of the region’s electricity supply, while directly benefiting more than 735 families. The works included a 349km medium voltage line built from the Vallem Substation to Baha Negra.

3. Assaad Razzouk’s tweet on Portugal closing its last existing coal plant

Assaad Razzouk, CEO of renewable energy company Gurin Energy, shared an article on Portugal closing its last existing coal plant in order to end the use of the highly polluting coal for energy generation. The Pego plant located in central Portugal was the second-highest emitter of greenhouse gases in the country. The closure of the plant enabled Portugal to achieve its goal of ending fossil fuel consumption for energy generation by 2030 earlier than planned.

Portugal became the fourth country in the European Union (EU) to end coal usage for power generation. Belgium, Austria, and Sweden were the first European countries to have ceased coal utilisation for power generation.  Francisco Ferreira, president of Environmental group Zero, stated that ceasing the use of coal for power generation will not suffice as renewable energy capacity in wind and solar will need to be scaled up.

4. Simon Evans’ tweet on International Energy Agency increasing its renewable energy forecast by 40% from last year

Simon Evans, deputy editor at climate and energy news and analysis website Carbon Brief, shared an article on International Energy Agency’s (IEA) Renewables 2021 report that increased renewable energy forecast by 40% from 2021. The global renewable energy capacity will reach 4,800GW by 2026 increasing by more than 60% from 2020. Furthermore, renewables will account for more than 95% of worldwide power capacity growth by 2026, with solar photovoltaic (PV) accounting for more than 50%. The amount of renewable capacity added between 2021 and 2026 will be 50% more than that added between 2015 and 2020 with the support from government regulations and renewable energy objectives established before and during the COP26 Climate Change Conference, according to the report.

China continues to dominate globally in terms of new capacity additions, with 1,200GW of total wind and solar capacity planned to be added by 2026, ahead of its current goal of 2030, the report added. The growth of renewables in India is also robust with the government aiming to add 500GW of renewable energy capacity by 2030.

5. Bill McKibben’s tweet on power generation company Drax withdrawn from the index of green energy companies

Bill McKibben, founder of climate change movement 350.org, shared an article on Drax being withdrawn from the index of green energy companies due to concerns over the sustainability of its biomass operations. Drax received £800m ($1bn) worth of renewable energy subsidies for converting its coal power generating units to produce electricity by burning biomass and was touted to become the world’s first carbon-negative energy company.

Financial services firm Jefferies, however, warned that bioenergy was unlikely to make a meaningful contribution to climate action due to concerns surrounding wood supplies, forest management policies, supply chain emissions, and emissions from combustion. Bioenergy with carbon capture and storage (BECCS) are no longer expected to be considered as zero-emission technology, the article noted. Drax could still receive billions in subsidies as the UK government may continue to support its plans. The company’s BECCS plans may cost British energy bill payers $42.2bn in 25 years and will not generate negative emissions, the article noted.
