NREL researchers recently published an article in the Journal of Photovoltaics tracking changes to the Transforming the Global Electricity
tracking changes to the world’s electricity supply over the past several years.
In 2022, 38% of the world’s electricity was delivered by carbon-free generation sources , similar to 2021. The global electricity system is still mostly powered by fossil energy, but it is undergoing an increasingly rapid rate of change. Despite lingering supply chain and trade issues around the globe, this is the second year in a row that more than 50% of new electricity generating capacity has been solar photovoltaic systems. Solar PV is now the most rapidly growing generation technology — 25% of total installed solar PV generation capacity was added in 2022 alone. PV’s share of global electricity generation rose from around 3.6% in 2021 to around 4.5% in 2022.

Capturing carbon dioxide with electricity: A microbial enzyme inspires electrochemistryHumans continuously emits greenhouse gases, worsening global warming. For example, carbon dioxide (CO2) accumulates dramatically over the years and is chemically very stable. Yet, some microbes capture CO2 using highly efficient enzymes. Scientists from the Max Planck Institute for Marine Microbiology in Bremen together with the Universities of Geneva and Radboud isolated one of these enzymes.
