Transition Is Enveloping U.S. Electricity Sector

first_img FacebookTwitterLinkedInEmailPrint分享Wall Street Journal:The rapid rise of wind and natural gas as sources of electricity is roiling U.S. power markets, forcing more companies to close older generating plants.Wholesale electricity prices are falling near historic lows in parts of the country with competitive power markets, as demand for electricity remains stagnant while newer, less-expensive generating facilities continue to come online.The changing American electricity landscape is pressuring power companies to shed unprofitable plants and reshape their portfolios to favor the new winners. Texas provides a clear example.Citing low gas prices and the proliferation of renewables such as wind and solar, Vistra Energy Corp., a vestige of the former Energy Future Holdings Corp., said it would retire three coal-fired facilities in Texas by early next year and that it plans to merge with independent power producer Dynegy Inc. Exelon Corp., the country’s largest owner of nuclear power plants, placed its Texas subsidiary under bankruptcy protection earlier this month, saying that “historically low power prices within Texas have created challenging market conditions for all power generators.”The average wholesale power price was less than $25 per megawatt hour last year on the grid that coordinates electricity distribution across most of Texas, according to the operator, the Electric Reliability Council of Texas. A decade ago, it was $55.Prices have fallen a similar amount on the PJM Interconnection LLC, the power grid that serves some or all of 13 states, including Pennsylvania and Ohio. A megawatt hour there traded for $29.23 last year, the lowest level since 1999, as far back as the grid’s independent market monitor tracks prices.The price drop at PJM reflects the construction of dozens of new gas-burning power plants, spurred by the abundance of the fuel due to the shale drilling boom. In 2006, 8% of the electricity in PJM was generated by natural gas. In 2016, it was 27%.Weak demand for electricity also has played a role, as Americans purchase more energy-efficient appliances and companies shave power consumption to cut costs. Last year, power demand in PJM grew 0.3% after falling the two previous years.In competitive regions in places like California, wholesale electricity is sold through daily auctions that favor the least-expensive sources of power. The resulting competition—by more power plants to buyers of roughly the same number of megawatts—has most-acutely impacted older coal and nuclear plants, which are struggling to provide competitively priced power. It has even begun to affect older natural-gas-fired facilities that have higher costs.An analysis by investment bank Lazard shows that on an unsubsidized basis and over the lifetime of a facility in North America, it costs about $60 to generate a megawatt hour of electricity using a combined-cycle natural-gas plant, compared with $102 burning coal and nearly $150 using nuclear. By that criteria, Lazard estimates electricity from utility-scale solar and wind facilities is now even cheaper than gas.A megawatt hour of electricity from utility-scale crystalline solar comes in at $49.50 and wind at $45. That metric carries an important caveat, however: It doesn’t factor in that wind and solar are more intermittent producers of power than conventional generation sources, since the sun doesn’t always shine and the wind doesn’t always blow.“It’s too late,” David Schlissel, a director at the Institute for Energy Economics and Financial Analysis, said of the Trump administration’s proposals. “The lesson is if you don’t put your thumb on the scale then gas and renewables will out-compete coal.”More: Electricity Prices Plummet as Gas, Wind Gain Traction and Demand Stalls Transition Is Enveloping U.S. Electricity Sectorlast_img read more

DOH-6: No studies show ‘tuob’ effective against coronavirus

first_imgPULMONES. PIA Steam inhalation may also increase secretion in the nose and could then possibly spread viruses through sneezing and coughing, she added. “Tuob” is the practice of steam inhalation where an individual covers his/her head with a towel or large piece of cloth to inhale steam from a small basin with hot water which can be infused with salt, lemon, ginger, or other ingredients. According to Pulmones, such therapy may pose more harmful effects and danger to individuals. It may also lead to accidents. “It could even cause burns,” Pulmones said. DOH-CHD 6 Local Health Support Division chief Dr. Ma. Sophia Pulmones said there are no studies providing evidences that inhalation of steam is effective against the virus. “There is no scientific evidence that it can eliminate SARS-CoV-2, the virus that causes COVID-19,” she said. ILOILO City – The Department of Health-Center for Health Development in Western Visayas (DOH-CHD 6) has warned the public against the use of “tuob” or steam inhalation to eliminate SARS-CoV-2, the virus that causes coronavirus disease (COVID-19). According to DOH, there are studies from the US Centers for Disease Control and Prevention and the World Health Organization that dismiss steam therapy as a cure for COVID-19.

Report:  27 Percent Of Adults Bullied At Work

Tribble/wikimedia.)INDIANAPOLIS, Ind. – While bullying is typically considered a schoolyard problem, millions of American adults say they’ve been victims of bullying on the job.According to a 2014 national survey from the Workforce Bullying Institute, 27 percent of workers report being bullied by a co-worker or boss.WBI Director Gary Namie says these victims face threats, humiliation, work sabotage and verbal abuse. He calls it a “silent epidemic” that typically occurs behind closed doors.“In adulthood, the bullies target the people who pose a threat to them,” says Namie. “So, based on envy, jealousy and attributes they don’t possess, like technical skill and being well liked, people are targeted.”October is Bullying Prevention Month, and Namie hopes it raises awareness about the effects of bullying on victims. He says it can traumatize a person, and even result in Post Traumatic Stress Disorder. An estimated 65 million Americans are affected by workplace bullying.In the workplace, Namie says victims often struggle to get employers to take their case seriously, that’s why employer accountability is an important part of anti-bullying legislation.“All the advice is, ‘Well, you need to confront your bully.’ Well, if you could’ve, you would’ve, and confrontation by a bully target is ineffective,” says Namie. “Not because they’re ineffective people, but because the power of the employer is behind the bully, not the target.”Namie’s organization has introduced a “Healthy Workplace Bill” in 26 states, but not yet Indiana. Namie says it defines an abusive work environment and provides protections, both for employees and employers. Mary Kuhlmanlast_img read more
