If you are seeing fewer fireflies each year, you’re not alone.  Like many insects, firefly populations are in decline.  A new study by researchers from the University of Kentucky, Bucknell University, Penn State University, and the USDA has shed some light on the precarious situation facing firefly populations across North America.  The research team used […]

There has been lots of talk recently about the transition to electric vehicles sputtering out.  Several automakers have delayed their EV programs citing reduced demand for the vehicles and lack of profitability.  In the bigger picture, the auto industry as a whole is in a rough patch as rising interest rates and other factors have […]

About 40% of the world‘s population lives in coastal regions.  People really like ocean-front property.  But worldwide, rising sea levels mean that more and more people want to live on land that may someday be swallowed up by the sea. One possible solution to the problem is to build cities on top of the water.  […]

Emperor penguins, the tallest and heaviest of all living penguins, are also the most famous, being the subject of a very popular documentary film.  The ongoing loss of sea ice in Antarctica has led to unprecedented breeding failures in emperor penguin colonies.  Since 2016, Antarctica has seen the four years with the lowest sea ice […]

For the past several years, the Swiss-based company Energy Vault has been developing an energy storage system based on the principle of using mechanical devices to lift heavy concrete blocks into stacks using power generated by wind turbines or other renewable sources.  When energy is needed, the blocks are lowered back to the ground, spinning […]

Palm oil is the world’s cheapest and most widely used vegetable oil.  In fact, more than 86 million tons of palm oil was consumed last year alone.  Even though few of us cook with it, palm oil can be found in approximately half of all packaged grocery items – everything from ice creams and pizzas […]

All across the country, electric utility companies are starting to use giant batteries to counteract the biggest weakness of renewable energy; namely, that the sun doesn’t always shine, and the wind doesn’t always blow.  Solar panels and wind turbines can keep generating energy when people don’t need it and batteries can store up that energy […]

Protecting coastal cities and towns from the dangers of tsunamis, storm surges, and sea-level rise has become an ever-increasing challenge.  There are so-called hard coastal defenses as well as nature-based solutions.  A new study by the University of Tokyo has found that combining the two types of defenses may be the most effective way to […]

In the forests of the Pacific Northwest, spotted owls have been the subject of environmental concern for more than 30 years.  Over the past 20 years, northern spotted owl populations have declined by up to 80% as the birds have faced marginalized territories and increasing numbers of wildfires.  Only about 3,000 of them remain on […]

Electricity demand in the U.S. continues to grow and, in the summer, homes and businesses crank up their air conditioning which drives demand even further.  Many East Coast cities are banking on offshore wind projects that are underway in the Atlantic Ocean to help meet that growing demand.  The first offshore turbines are now producing […]
