“Cow manure is a sticky problem for the climate”

“Dairy farms produce a lot of milk, but they also produce a lot of manure – more than one hundred pounds per day per adult cow. Many farms use large amounts of water to flush animal waste into “manure lagoons” where it breaks down without oxygen. The process releases methane, a potent global warming gas.”

“New Air-breathing battery can store electricity for a fifth the current cost”

“Wind and solar power are increasingly popular sources for renewable energy. But intermittency issues keep them from connecting widely to the U.S. grid: They require energy-storage systems that, at the cheapest, run about $100 per kilowatt hour and function only in certain locations. Now MIT researchers have developed an “air-breathing” battery that could store electricity for very long durations for about one-fifth the cost of current technologies, with minimal location restraints and zero emissions.”

“Was Your Seafood Caught With Slave Labor? New Database Helps Retailers Combat Abuse”

“The Monterey Bay Aquarium’s Seafood Watch program, known best for its red, yellow and green sustainable seafood-rating scheme, is unveiling its first Seafood Slavery Risk Tool on Thursday. It’s a database designed to help corporate seafood buyers assess the risk of forced labor, human trafficking and hazardous child labor in the seafood they purchase. The tool’s release comes on the heels of a new report that confirms forced labor and human rights abuses remain embedded in Thailand’s fishing industry, years after global media outlets first documented the practice.”

“Stanford engineers develop a new method of keeping the lights on if the world turns to 100% clean, renewable energy”

Researchers propose three separate ways to avoid blackouts if the world transitions all its energy to electricity or direct heat and provides the energy with 100 percent wind, water and sunlight. The solutions reduce energy requirements, health damage and climate damage.

“San Francisco’s Tallest Building Makes Big Water Recycling Statement”

“Of particular interest to me, Salesforce Tower will also house the largest water recycling system in a commercial high-rise building in the United States. A black-water system will recycle all of the water used in the building to be available again for nonpotable uses, saving about 30,000 gallons of freshwater a day.”

“The Forgotten Renewable: Geothermal Energy Production Heats Up”

“Geothermal energy uses the earth’s natural heat to create electricity. While there are several different ways to accomplish this, the most common is to take super-heated water from geothermal hot spots and pipe it to the surface. It then turns into steam and spins a turbine, which generates electricity. It’s completely renewable, and generates clean energy around the clock, unlike wind and solar.”

“Massachusetts tops list of top 10 states for LEED”

“Massachusetts, once again, is the top state for LEED, according to the U.S. Green Building Council’s annual Top 10 States for LEED ranking. In 2017, the state, which also held the title of No. 1 in 2016, saw nearly 4.5 square feet per capita (130 projects; 29 million total square feet) win LEED certification, an increase from the 3.73 square feet per capita that was certified there in 2016.”

“Two countries are the reason the EU is hitting its ambitious renewable energy targets”

“The EU now gets more than 30% of its electricity from renewable sources, up from 12% in 2000. At the current rate of growth, the European bloc can increase the proportion of renewables in its electricity mix to 50% by 2030, according to a new report (pdf) published by think tanks Sandbag and Agora Energiewende.”

“Wind Is Expected to Blow Past Water to Become the Renewable Resource Leader”

“Hydroelectric power plants (a.k.a. water and dams) have long been the leading source of renewable electricity in the United States. However, wind power is expected to surpass hydroelectricity by 2019, according to a new forecast published this month by the Energy Information Administration (EIA).”
