Earlier this month, DTE Energy announced a rate hike for LED lights. The decision sparked anger in Michigan city officials involved in municipal streetlight conversions, who would see their financial incentives for energy conservation diminish. At the same time, DTE plans to lower its rates on sodium lighting, which can use up to three times more electricity than LED.
In 2014 Ypsilanti, best known as the home of Eastern Michigan University, converted all 1,100 of its streetlights to LED — making it the first Michigan municipality to do so. City leaders worked with DTE Energy on the project and expected to see substantial annual energy savings. In the first year, the municipality’s DTE energy bill was 29 percent lower, saving $176,000. Now, with DTE’s proposed rate increase, Ypsilanti’s city leaders are seeing their expected savings disappear.
Streams within approximately 40% of the global land surface are at risk from the application of insecticides. These were the results from the first global map to be modeled on insecticide runoff to surface waters, which has just been published in the journal Environmental Pollution by researchers from the Helmholtz Center for Environmental Research (UFZ) and the University of Koblenz-Landau together with the University of Milan, Aarhus University and Aachen University. According to the publication, particularly streams in the Mediterranean, the USA, Central America and Southeast Asia are at risk.
It started with a trip to the basement of the American Museum of Natural History in New York to inspect preserved animal hides. Later, Georgia Institute of Technology researchers built a wind tunnel about 2 feet tall, complete with a makeshift eye. By putting both steps together, the team discovered that 22 species of mammals – from humans, to hedgehogs, to giraffes – are the same: their eyelash length is one-third the width of their eye. Anything shorter or longer, including the fake eyelashes that are popular in Hollywood and make-up aisles, increases airflow around the eye and leads to more dust hitting the surface.
The Bureau of Land Management’s proposal to offer new oil and gas leases on 89,000 acres in northwestern Wyoming would have devastating effects on greater sage grouse, including allowing industrial operations in some of the birds’ most important nesting and rearing habitat, according to comments submitted to the agency this week by the Center for Biological Diversity. Even though sage grouse have declined 60 percent over six years in Wyoming, the plan repeatedly ignores federal scientists’ recommendations for protecting these prairie birds from fossil fuel development.
“Rather than protecting these vanishing birds, the BLM is proposing to hand over some of their last remaining habitat to the oil and gas industry,” said Michael Saul, an attorney with the Center. “A few companies may squeeze some short-term profits out of it, but the long-term effect will be pushing these great prairie birds toward extinction.”
Researchers in Australia have found that corals commonly found on the Great Barrier Reef will eat micro-plastic pollution. “Corals are non-selective feeders and our results show that they can consume microplastics when the plastics are present in seawater,” says Dr Mia Hoogenboom, a Chief Investigator with the ARC Centre of Excellence for Coral Reef Studies at James Cook University.
Solar energy plants will soon deliver the most inexpensive power available in many parts of the world within a decade, according to a new analysis of the levelized cost of electricity (LCOE). By 2025, the cost of producing solar power in the UK will have declined to between 4.2 and 10.3 pence per kilowatt hour (p/kWh), and by 2050 to as low as 2.0 to 7.4 p/kWh, according to a study by the Fraunhofer Institute for Solar Energy Systems commissioned by Agora Energiewende.
A large Australian study of more than 200,000 people has provided independent confirmation that up to two in every three smokers will die from their habit if they continue to smoke.
The research, published today in the international journal BMC Medicine, is the first evidence from a broad cross-section of the population to show the smoking-related death toll is as high as two thirds.
Botanists from Trinity College Dublin have made a breakthrough discovery that could save barley farmers sleepless nights and millions of Euro each year: naturally occurring plant-friendly fungi prevent crop-ravishing diseases from spreading, and also aid plant survival in testing environmental conditions. Importantly, these amazing little organisms cause no harm to the plant roots in which they take up their abode. However, their gift of immunity against common seed diseases greatly reduces the need for farmers to spray environmentally damaging chemicals, which can affect ecosystems in a plethora of negative ways.
By studying African lake sediments from the past 20,000 years, scientists are learning more about abrupt climate shifts, advancing their understanding of changing weather patterns. In a recent paper published in Nature Geoscience, co-author on an NAU assistant professor Nicholas McKay analyzes core samples from Lake Bosumtwi in Ghana. The isolated lake was formed by a meteor and sits like a bowl on the landscape giving scientists a clear view of environmental changes.
The day I first set foot in a tropical rainforest, in Malaysia in the early 1980s, I experienced something profound. From the echoes of gibbons calling from the canopy in the early morning mist to the iridescent flash of a bird in a beam of sunlight, rainforests are a sensory delight as well as a marvel to anyone’s scientific curiosity. As I subsequently watched these forests dwindle and, in some cases, vanish, I have felt an equally profound sense of loss and a nagging guilt that I was somehow part of the story, because I had done little to remedy the situation.
