Transitioning to renewable energy systems might not entail a decline in net energy

Energy researchers have been trying to understand the implications of a transition to fully renewable energy for decades. Some past studies suggested that technologies to generate energy from renewable energy sources, such as solar panels and wind turbines, might not generate as much net energy (i.e., the energy remaining after accounting for the energy consumed to generate power) as their long-standing fossil fuel-reliant counterparts.

Battery passports... you may not have heard much about them yet, but they are a critical part of a better future. Every large battery will have these, and really, plenty of other products need something like this too. Hooray for that future starting now!

"Volvo Cars is launching the world's first EV battery passport recording the origins of raw materials, components, recycled content and carbon footprint"

Australian Communities Push Back Against Big Renewables - PV Magazine

Fortunately, the pro #RenewableEnergy groups recognize the importance of community engagement and seem to understand the process. Here's hoping to see sustained renewable power deployment.

Australian communities push back against big renewables

As the Australian authorities launch rolling tenders for 32 GW of renewables and storage by 2030, it has become clear that some communities, including locals around <b>pv magazine</b> reporter <b>Bella Peacock</b>’s hometown, have not been brought onside. Heated debate on social media and a frenzy stoked by concerns about the impact on the natural environment are throwing up hurdles for renewables development.

Polyester is being examined as an alternative reverse-osmosis membrane material to the incumbent polyamide. The promised advantages of polyester over polyamide include enhanced resistance to biofouling, chlorine and mineral scaling.

Furthermore, polyester membrane fabrication process is similar to that of state-of-the-art polyamide membranes.

Greater access to clean water, thanks to a better membrane

Water scarcity around the world is a bigger problem than ever, and desalination is critical to solving it. The best available technologies for separating salt from seawater, though, are costly and require a great deal of maintenance.
