Solar device generates electricity and desalinates water with no waste brine

Physics World

A device that can generate electricity while desalinating seawater has been developed by researchers in Saudi Arabia and China, who claim that their new system is highly efficient at performing both tasks. The device uses waste heat from the solar cell for desalination, thereby cooling the solar cell.

September Is Here. That Means Another Nail-Biter for California’s Grid.

Union of Concerned Scientists

For California power grid experts, September is a nerve-wracking month, still very much part of danger season on the West Coast. At any point in the summer, extreme heat could trigger electricity supply shortages and rotating power outages. But September is the month when this type of power outage is most likely in California.

In Climate Talks, Plans to Keep Planet from Overheating Should Not Ignore Water

Circle of Blue

Coal power, from mining to generation, is among the thirstiest and most polluting ways to produce electricity. Wind turbines and solar power, two sturdy and growing sources of renewable energy, require negligible amounts of water. Rivers provide a cooling effect on nearby lands, functioning as a natural air conditioner.

The Missing Piece of the Renewable Energy Revolution

HumanNature

In 2022, the installed capacity of wind and solar power grew almost 10% in the United States [1]. On the other end of the electric grid, advanced technologies can help reduce the amount of energy that is required for basic services like lighting, heating, and cooling. This would cost $17.10 References: [1] U.S.
