Global renewable capacity increased by 295 GW last year, bringing the world to a cumulative installed capacity of 3,372 GW, according to the International Renewable Energy Agency (IRENA).

Capacity factor is often discussed when evaluating and comparing the efficiency and performance of solar farms. However, looking just at this metric can be misleading as it ignores many underlying technical and commercial factors, as solar farm specifications almost never align for a simple apples-to-apples comparison.

An international group of researchers has calculated the potential for floating solar across the world. The results show a generation potential of 9,434 TWh per year across 114,555 global reservoirs, with 30% of their area covered. The United States leads with 1,911 TWh per year of potential, with Australia coming in 8th, with 210 TWh per year.

University of Sydney researchers Sophie Webber and Gareth Bryant highlight the key challenges of land, labour and finance in achieving a renewable energy transition in Australia.

A team of Australian researchers have discovered a “natural battery” that converts air into energy and has “considerable” potential to support the future development of small, sustainable air-powered devices.

Australia’s utility-scale solar sector had its third highest month on record in February, generating 1,463 GWh. New South Wales was the country’s top generator, showing the state’s colossal coal turnaround is well underway.

Cornell University researchers have discovered that soybeans planted beneath 3.9-meter-high solar modules can positively affect panel temperatures and the microclimates of farms.

Western Australian solar window company ClearVue Technologies has won a tender to complete a study of its electricity generating glazing technology, which will be installed at a Hong Kong government department’s headquarters as part of a fully-funded field trial.

German scientists have investigated the role of surface texturing in perovskite-silicon tandem cells and have found that several new processes offer the ability to etch smaller, more uniform textures onto the surface of a silicon cell than today’s industry standard. This could help to ease the subsequent growth of a perovskite cell on top of the silicon, enabling researchers and manufacturers to target higher performance.

A report from consultancy Climate Energy Finance finds that Australia and New Zealand have a more than $10 billion (USD 6.7 billion) pipeline of investment proposals in resource value-adding critical minerals, including in lithium, nickel, cobalt, vanadium, rare earths, hydrogen electrolysers, green ammonia, and value-added downstream battery developments.
