Can the Zaporizhzhia Nuclear Plant Avoid a Major Disaster?

Union of Concerned Scientists

It has been reported that on August 25, the plant temporarily lost all of its off-site electrical power from the grid, which is essential for its safe operation, forcing it to rely on on-site backup power. That could lead to loss of the cooling ponds, which are needed to cool the plant’s diesel generators, enabling them to function.

What 115°F in California’s Central Valley Feels Like

Union of Concerned Scientists

The AC doesn’t work (or you don’t run it because there go your wages), but at least the pedestal fan pointed directly at your body and some cool water help. Under the sun, the sensation is stronger because solar radiation is heating up your body.

Five Things the “Nuclear Bros” Don’t Want You to Know About Small Modular Reactors

Union of Concerned Scientists

SMRs are nuclear reactors that are “small” (defined as 300 megawatts of electrical power or less), can be largely assembled in a centralized facility, and would be installed in a modular fashion at power generation sites. What are SMRs? Some proposed SMRs are so tiny (20 megawatts or less) that they are called “micro” reactors.

With Climate Change, Nights Are Warming Faster than Days. Why?

Union of Concerned Scientists

That often brings to mind images of people trying to catch some shade under a baking hot sun or city kids cooling off in a fountain while their parents sweat on the sidelines. The types of clouds that have increased—specifically thick, precipitating clouds —reflect sunlight back into space during the day and have a cooling effect.

Solar panels can heat the local urban environment, systematic review reveals

Physics World

The researchers suggest future work should focus on increasing the reflectance of wavelengths of sunlight not converted to electricity. Specifically, we found that photovoltaics can significantly warm the urban environment during the day, but typically cool the urban environment at night. What research did you include in your study?

Solar cell keeps going after sunset

Physics World

A new type of photovoltaic cell continues working after sunset thanks to an additional generator that harvests electricity from the temperature difference between the cell and its surroundings. At night, the cells lose heat to their surroundings, leaving them several degrees cooler than the ambient air due to radiative cooling.

Glossary of Greenhouse Gas Terms

Greenbuilding Law

Albedo The amount of solar radiation reflected from an object or surface, often expressed as a percentage. It also includes greenhouse gases that come from producing the goods or services that the individual uses, including emissions from power plants that make electricity, factories that make products, and landfills where trash gets sent.
