DOI: 10.1021/acs.est.2c00001 Fracking for natural gas in parts of Pennsylvania with a legacy of energy extraction may increase the risk of groundwater contamination, according to a team led by Penn State scientists. The researchers found a potential link … Read more

Three ways the fossil fuel industry failed women, and how clean energy can learn from their mistakes

A crucial outcome of Australia’s jobs summit last week was the commitment to review programs aimed at boosting the number of women in science, technology, engineering and mathematics (STEM) careers. Energy is a particularly male-dominated STEM industry, with clean energy on the brink of massive expansion. However, to ensure the clean energy industry is truly … Read more

The energy transition needs to be climate-proof

Less talked about is how they can also disrupt the deployment of renewable energy infrastructure that’s … Read more

Researchers quantify the amount of energy that plants use to lift water on a global scale

A stand of quaking aspens pump water up to their canopies in southwestern Colorado. Credit: Leander Anderegg Every day, about one quadrillion gallons of water are silently pumped from the ground to the treetops. Earth’s plant life accomplishes this staggering feat using only sunlight. It takes energy to lift all this liquid, but just how … Read more

Dark energy eludes astronomers studying 100 million galaxies

Scientists are still coming up empty in the hunt for flaws in Einstein’s theory of general relativity that could explain the mysterious force driving the accelerating expansion of the universe. The researchers studied 100 million galaxies looking for signs that the strength of gravity has varied throughout the universe’s history or over vast cosmic distances. … Read more

Scientists help probe dark energy by testing gravity

This image – the first released from NASA’s James Webb Space Telescope – shows the galaxy cluster SMACS 0723. Some of the galaxies appear smeared or stretched due to a phenomenon called gravitational lensing. This effect can help scientists map the presence of dark matter in the universe.

New stable quantum batteries can reliably store energy into electromagnetic fields

Two examples of “quantum phones”, both charged by quantum batteries based on electromagnetic fields. On the left, a charging protocol not using a micromaser approach leads to uncontrolled battery charging with possible damages. On the right, a charging protocol based on micromasers is able to self-control the amount of charge deposited into the quantum phone. … Read more

Spending green bucks to spur green energy

Credit: Pixabay/CC0 Public Domain After decades of inaction in the face of escalating natural disasters and sustained global warming, Congress hopes to make clean energy so cheap in all aspects of life that it’s nearly irresistible. The House is poised to pass a transformative bill Friday that would provide the most spending to fight climate … Read more

A new method boosts wind farms’ energy output, without new equipment

Credit: Pixabay/CC0 Public Domain Virtually all wind turbines, which produce more than 5 percent of the world’s electricity, are controlled as if they were individual, free-standing units. In fact, the vast majority are part of larger wind farm installations involving dozens or even hundreds of turbines, whose wakes can affect each other. Now, engineers at … Read more

Where do electrons get energy to spin around an atom’s nucleus?

An atom is best visualized as a tight, dense nucleus surrounded by buzzing, orbiting electrons. This picture immediately leads to a question: How do electrons keep whirling around the nucleus without ever slowing down? This was a burning question in the early 20th century, and a search for the answer ultimately led to the development … Read more
