Top 5 Friday – July 22

1. A picture's worth 1000 words, but how much is a tweet that advocates for actual impactful change worth? Do you agree?

2. Europe's surging electricity prices are shattering records

by Kate Marino, Axios

“A perfect storm of soaring natural gas prices triggered by Russian supply issues, high coal prices, low wind speeds and scorching weather is driving the price moves, the research firm wrote in a recent note.”

3. Declaring a climate emergency could unlock potent tools for Biden — at a steep cost

By Alex Guillén and Ben Lefebvre, Politico

"Invoking a national emergency over climate change would enable President Joe Biden to unleash sweeping actions to restrain greenhouse gas production — such as banning U.S. crude oil exports, ending offshore drilling or speeding the manufacturing of electric vehicles.

But some of those steps would be politically explosive, and could even prove ruinous to his party’s fortunes by sending gasoline prices soaring. Others would threaten to alienate European allies looking to U.S. fuel supplies to ease their dependence on Russia. And any executive actions Biden takes would run the risk of falling to the same conservative Supreme Court that has already hobbled his regulators’ ability to rein in carbon pollution."

4. TIL about Hydrogen Energy

MIT’s TILclimate podcast gives a nice overview of the emerging fuel of hydrogen energy. Accessible for every level of science understanding! 


5. Meet a startup that plans to use mining waste to capture carbon dioxide

By Maria Gallucci, Canary Media

What makes Travertine unique is that it’s also focused on cleaning up the mining sector. When mining companies dig for metals and minerals, they leave behind enormous piles and ponds of residual rocks, chemicals and contaminated water. Deposits of mine “tailings” are only expected to grow in the coming years as the demand for metals soars, driven by the increasing need for electric-vehicle batteries and other clean energy technologies.

Travertine aims to curb that waste in two ways: by recycling chemicals used during mineral extraction and by transforming leftover rock into CO2 sponges.
