A commission that oversees water quality for the watershed that supplies Philadelphia and half of New York City with drinking water took another step Thursday toward permanently banning natural gas drilling and hydraulic fracturing, despite industry opposition. The Delaware River Basin Commission's newly published draft regulations would enact a formal ban on fracking, as well as put additional restrictions to make it harder, if not impossible, for the industry to dispose wastewater within the watershed or use water from the river and its tributaries for fracking outside the basin.
Chernobyl is being developed into a solar power site.Two companies have a contract to start building a one-megawatt solar farm next month, and they're planning on adding 99 more megawatts in the future.
A new study out of the Zuckerberg Institute for Water Research suggests the treated waste from turkeys, chickens, and other poultry could replace up to ten per cent of the coal used in electricity production. Scientists say poultry waste generates heat at high temperatures and combusts in a similar manner to coal, making it a good renewable energy replacement. Disposing of poultry waste in an environmentally-friendly manner is an ongoing problem for farmers. Converting it into energy could help solve that issue.
Despite a major push from the Midwest to bolster Renewable Fuel Standard volumes for biomass-based diesel and cellulosic ethanol, in the end, the U.S. Environmental Protection Agency left its final numbers released on Thursday virtually untouched from the original proposal. Though the biodiesel industry pressed President Donald Trump's administration for higher biomass-based diesel volumes above the proposed 2.1 billion gallons for 2019, the EPA left that number unchanged. The agency originally proposed a cut, while the industry wanted the number set at 2.5 billion gallons.The EPA's final biomass-based diesel numbers came as a huge disappointment to an industry that maintains it has the capacity to produce 2.6 billion gallons. Corn ethanol blending requirements were set at 15 billion gallons for 2018, with overall biofuel blending obligations slightly higher overall, based on the final RFS volumes announced. Fifteen billion gallons of corn ethanol amounts to about 5.4 billion bushels of corn demand supported by the RFS.The overall total Renewable Volume Obligation, or RVO, for 2018 was set at 19.29 billion gallons. That represents a slight bump from the original proposal of 19.28 billion gallons. The agency had considered cutting the number to 19.24 billion gallons. The bump comes from a slight increase in the advanced biofuels volumes.
CRISPR technology will ultimately impact what we eat, wear, and how we maintain our health — and it just crashed successfully into the big party known as the Advanced Transportation revolution. Specifically, a new path to producing fuel molecules that replace diesel. For some time we have seen tremendous activity around the development of CRISPR gene-editing technology — allowing scientists to directly clip and insert genetic material.Now, Fuzhong Zhang, associate professor at the School of Engineering & Applied Science updated the Digest this week and noted that “We designed and then constructed a synthetic metabolic pathway inside the fast-growing E.coli by introducing genes from other species, including Staphylococus aureus, cyanobacteria and soil bacteria. By using CRISPR, we incorporated genes from different species with favorable traits into E.coli’s fatty acid pathway.”Zhang’s research focuses on engineering metabolic pathways that, when optimized, allow the bacteria to act as a biofuel generator. In its latest findings, recently published in Biotechnology for Biofuels, Zhang’s lab used the best bits of several other species — including a well-known pathogen — to enable E.coli to produce branched, long-chain fatty alcohols (BLFLs).
The largest coal plant in the Western United States will keep operating through 2019 after its owners received approval from the federal Bureau of Reclamation and Bureau of Indian Affairs to extend its lease on Wednesday. The plant's owners, including Reclamation and a group of utilities, had planned to close the 2,250 MW Navajo Generating Station (NGS) in 2018. The Navajo Nation, which owns the land on which the plant sits, voted to extend its lease until 2019, but needed final approval from the federal agency. Arizona utility Salt River Project (SRP) and other owners still plan to shutter the facility after its lease expires, citing competitive pressures from cheap natural gas. The Navajo Nation and coal supplier Peabody Energy are working to find a new owner for the plant.
As renewable energy prices drop, schools are saving millions, while teaching students about technology. Their solar capacity has nearly doubled in three years. The number of schools powered by solar is growing quickly. About 5 percent of all K-12 U.S. schools are now powered by the sun, and their solar capacity has almost doubled in the last three years, according to a new study by the Solar Energy Industries Association (SEIA), The Solar Foundation, and Generation 180, a clean energy nonprofit.The nearly 5,500 schools using solar power today have a total of 910 megawatts of solar capacity, enough to power 190,000 homes, according to the study.The biggest reason for the surge is the economic benefits of solar energy. Drastic declines in price have made it financially viable for schools. Both public and private schools are reducing their electricity bills with solar, leaving them more money to spend on educational programs, according to the research. Many are also incorporating renewable energy into their science, technology, engineering and math (STEM) lessons.
Despite a unanimous vote by a citizen’s air pollution board earlier this month, Virginia faces several hurdles, including possible court and legislative challenges, before it could join a regional carbon emissions trading network. “The biggest threat,” said Will Cleveland of the Southern Environmental Law Center, is “legislation in the General Assembly attacking or rolling back DEQ’s (Department of Environmental Quality) authority to address carbon pollution or some sort of budgetary maneuver to defund DEQ’s efforts.”“In court,” Cleveland added, “I’d anticipate litigation similar to (opponents’) challenges to the Clean Power Plan, attacking DEQ’s authority to regulate carbon.”The DEQ is the agency coordinating Virginia’s bid to link up with the Regional Greenhouse Gas Initiative, or RGGI, by early 2019.State Sen. Frank Wagner, who chairs the committee that presides over energy legislation in that chamber, has promised to bring in “all of the key players” with a “barrage of questions about the legality” of Gov. Terry McAuliffe’s executive directive to link up with RGGI as a state-based replacement for the Clean Power Plan.
In 2014, Stanley Sturgill traveled 1,300 miles from his home in Harlan County, Kentucky, to Denver, where the Environmental Protection Agency held one of four public hearings and 11 listening sessions on new rules to limit pollution from power plants. The retired coal miner ― diagnosed with black lung and chronic obstructive pulmonary disease from his years toiling underground ― begged the agency for help: “We’re dying, literally dying for you to help us.”On Tuesday, Sturgill, 72, drove three hours to Charleston, West Virginia, for the EPA’s only public hearing on the Trump administration’s proposal to repeal the Obama-era Clean Power Plan. Hunched in front of a microphone at a rounded wooden table in the Senate Judiciary Committee Room of the West Virginia Legislature, he made his plea once again: “We’re still dying ― we’re still literally dying ― for you to help us.”“Just how many people must pay the supreme price of death for a few rich, greedy people to bank a few dollars?” Sturgill said. He noted how long he and his wife, Sharon, had trekked just to speak for a few minutes. “We may be old, but we still love living.”His testimony, about 90 minutes into the 9-to-5 hearing, punctuated a morning packed with fawning praise for President Donald Trump, back-patting Republican lawmakers, and exhausted public health advocates who’ve spent years repeating the same statistics on climate change and asthma.“Do I really think that this administration cares what this old, worn-out coal miner has to say? Well, I don’t know. I really doubt it. But I had to be here,” Sturgill said, “as long as I can draw breath.” The EPA estimates the social cost of carbon ― climate-change related damages to property, human health, economic growth and agriculture ― to be between $11 and $105 per ton of carbon dioxide pollution. But the real cost could be 129 times higher, according to a study released this month from Purdue University, which found that existing models relied on decades-old agricultural data.
In a filing with the state Public Service Commission, Ameren said its Renewable Choice Program would enable certain customers to “subscribe” to wind energy for up to 100 percent of their average energy needs. The move comes on the heels of the utility’s September announcement that it will invest $1 billion in new wind generation — its biggest commitment yet to renewable energy.
