Quantum science & technology: Highlights of 2021

Physics World

Last month, Physics World reported on a campaign to make 2025 the official UN International Year of Quantum Science and Technology. Although we wish the campaigners well, here at the magazine’s socially-distanced HQ we’ve already found plenty to celebrate in 2021, thanks to researchers around the world. Here are a few highlights.

Can Solar, Storage and Efficiency Help Us Survive Winters Like This?

Union of Concerned Scientists

In 2021, Winter Storm Uri killed at least 246 Texans. This means that for an indefinite amount of time—depending on the cause of the outage —a home can go without electricity for lighting, heating, cooling and other needs that people depend on every day. Eight percent of those deaths were attributed to carbon monoxide poisoning.

Ask a Scientist: The US Has to Do More to Meet Its Carbon Emissions Reduction Goals

Union of Concerned Scientists

The legislation committed nearly $400 billion to support, among other things, wind and solar power, battery storage, electric vehicles, and other clean energy technologies that will make a significant dent in US heat-trapping emissions. Last year, Congress passed the most ambitious climate bill ever enacted, the Inflation Reduction Act.

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

Circle of Blue

By Brett Walton, Circle of Blue – September 23, 2021. But other low-carbon technologies do not tread as lightly. Nuclear plants hoover up enormous volumes of water for cooling, killing aquatic life and warming rivers in the process. Rivers provide a cooling effect on nearby lands, functioning as a natural air conditioner.

New Study Finds Low Awareness Among Ontarians About Eco-friendly Technologies that can Cut Energy Bills

Enviromental Defense

Heat pumps, a simple but effective technology, use electricity to remove heat from inside your home to cool it in the summer and pull heat in from outside to heat your home in the winter. Stats Canada ’s most recent statistics report that just six per cent of Canadian homes relied on heat pumps in 2021.

Are EV Batteries Recyclable?

Union of Concerned Scientists

EVs are a newer technology, and their batteries require different end-of-life processing than gasoline vehicles. They connect multiple EV batteries together, along with battery monitoring and cooling technology, to create a larger battery that is about the size of a shipping container. Slattery et al.
