As solar energy experiences record growth, investors, customers, and regulators are increasingly asking for more disclosure and transparency on how solar supply chains are managed throughout product life cycles.

In a financial world of stocks, bonds, foreign exchange, and credit cards, trillions of dollars are traded daily, with money flows handled by a bevy of databanks. In the world of cryptocurrency, billions of dollars worth of Bitcoin are traded through as many as 400,000 transactions per day, consuming the energy supply of a modernized country. The quirk is a “proof of work” feature that provides decentralized security. Is Bitcoin’s energy usage all for nothing, or is it a game-changer for renewable assets and generators? Tristan Rayner explores.

An initial 1.44 MW of solar panels this year appears to have impressed the Seven-Up Bottling Company sufficiently to persuade the business to opt for another 10.5 MW of arrays on its factories.

A report published by BloombergNEF for the COP26 climate change summit has listed global commitments by cities, states, provinces and nations to end the sale of new fossil-fueled vehicles but, with 2035 estimated as the cut-off date for zero-emission roads by mid century, policymakers need to be more ambitious.

Join pv magazine and solar industry leaders as we meet for the USA Roundtables 2021 today, from 10:00 AM to 5:00 PM EST.

Efforts are being made to come up with a less convoluted approach to planning farm-based solar systems, in the only EU member state which explicitly apportioned funds for agrivoltaics in its post-Covid spending plans.

With green hydrogen needed to produce the ‘e-ammonia’ required for carbon-free vessels, new clean power generation capacity and potential solar power hotspots near international shipping lanes will be crucial.

Norwegian hydropower giant and Europe’s largest renewable energy generator, Statkraft, has published its annual “Low Emissions Scenario”, which describes investment in green projects as “unstoppable”, while calling for a dramatic scaling up for renewables, electrification and green hydrogen.

US data management company Iron Mountain has a growing portfolio of onsite and PPA renewables, and it’s one of the first major corporate firms to track its renewables by the hour as part of an innovative PPA that may serve as a forerunner for widespread 24/7 matching.

Mining giant Rio Tinto has been on the back-foot since its destruction of 46,000-year-old sacred indigenous sites last year, costing one chief executive his job and one country a timeless piece of its cultural heritage. Along with the impacts of Covid-19 and stock price decline, the company is seeking to rebuild its brand with improved emissions reduction targets, which will see multi-gigawatt solar and wind installations.
