Giant batteries and the grid
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 […]

Natural solutions for coastal defense
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 […]

Good owls and bad owls
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 […]

Offshore wind and the wake effect
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 […]

Balloon release laws
The Florida state legislature has recently passed a law that bans the intentional release of helium balloons outdoors. It is a rare example of a bipartisan piece of legislation. Florida is joining six other states that have already enacted balloon restricting laws. Balloons released into the sky don’t just disappear into the ether. They often […]

A setback for New York offshore wind
Three major offshore wind projects in New York have been cancelled because of the unavailability of technology critical to the projects. The projects were part of NYSERDA‘s third offshore wind solicitation and were provisionally awarded last October. The projects, which totaled more than 4 GW of clean energy, were supposed to begin commercial operation in […]
