Coal’s end may be on the horizon FacebookTwitterLinkedInEmailPrint分享Bloomberg:Should we just give up now?The world’s electrical utilities need to reduce coal consumption by at least 60 percent over the two decades through 2030 to avoid the worst effects of climate change that could occur with more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) of warming, the Intergovernmental Panel on Climate Change announced Monday.Such a target seems wildly ambitious: Even Bloomberg New Energy Finance, which tends to be more optimistic than other analysts (and more accurate) about the speed of energy transition, expects coal-fired generation to increase by 10 percent over the period. Hold on though. Is it really such a stretch?After all, U.S. coal-power generation decreased by about a third in the seven years through 2017, to 12.7 billion British thermal units from 18.5 billion, based on data from energy-market consultancy Genscape Inc. In the European Union, black-coal generation fell by about the same proportion over just four years through 2016, according to Eurostat, to 385,925 gigawatt-hours from 544,279 GWh.Across Europe and the U.S., the decline in coal output recently has averaged close to 5 percent a year. If the world as a whole can reach 7 percent a year, it would be on track to meet the IPCC’s 2030 target. The conventional wisdom is that this isn’t possible, as rising demand from emerging economies, led by China and India, overwhelms the switch from fossil fuels in richer countries. That may underestimate the changing economics of energy generation, though.The mainstream view is still that we can’t decarbonize our electricity system fast enough to meet the IPCC’s targets. But a decade ago, the current situation of plateauing demand for coal and car fuel and cratering renewables costs looked equally outlandish. Given the way the world’s energy market has changed in recent years, it’s a good idea to never say never.More: The end of coal could be closer than it looks
London: Tottenham edged Southampton 3-2 in an FA Cup fourth-round replay that was decided on a penalty conversion by Son Heung-min shortly before the start of second-half stoppage time.The teams had to square off in a rematch on Wednesday after their initial fourth-round encounter on January 25 had ended in a 1-1 draw, reports Efe news.Jose Mourinho’s men jumped out to an early lead at the 11-minute mark at Tottenham Hotspur Stadium in north London when a shot by French midfielder Tanguy Ndombele ricocheted off defender Jack Stephens and travelled out of the reach of net minder Angus Gunn and into the goal.But the Saints were unfazed by the early deficit and mostly outplayed Tottenham over the remainder of the contest.In the 19th minute, Danny Ings had a golden chance to score the equaliser from just outside the six-yard box, but his shot slammed off the crossbar.The visitors managed to knot the game at 1-1 15 minutes later, however, when a poor block by Tottenham goalkeeper Hugo Lloris set up Southampton striker Shane Long for a short-range finish.The Spurs were able to preserve the tie heading into halftime despite a very unconvincing performance, while the Saints’ strong showing was marred by an apparently serious knee injury suffered by midfielder James Ward-Prowse.Ward-Prowse was in visible agony and had to be taken off on a stretcher in the 39th minute after young Tottenham winger Ryan Sessegnon caught him with his studs on a clearance.Both teams had good chances to score early in the second half, with Sofiane Boufal and Lucas Moura failing to convert chances for Southampton and Tottenham, respectively.Finally, the visitors grabbed the lead when Ings scored on a curving strike just inside the post in the 72nd minute.Moura scored the 2-2 equaliser with a right-footed shot in the 78th minute and then Son was brought down in the area by the Saints’ net minder eight minutes later. The South Korean did the honours himself on the penalty try, stepping up to the spot and slotting the ball home for the winner.Tottenham will next square off at home in the first week of March against Norwich City in the fifth round (round of 16) of this annual English knockout football competition.Matches in that round will not be replayed, so if the Spurs-Norwich contest is tied at the end of regulation extra time, penalties will determine who reaches the quarterfinals.

Sophomore Armaan Premjee, who was arrested on Tuesday on charges of sexual assault, remains at USC, but is no longer a member of the Kappa Sigma fraternity.Los Angeles Police Department officers arrested Premjee at 11 a.m. on Tuesday. He was held at the Metropolitan Detention Center until he posted $100,000 bail at 7:53 p.m.The alleged sexual assault took place at Fluor Tower residence hall around 1 a.m. on April 1, according to Department of Public Safety logs. University officials could not provide details about who reported the incident. Information about the victim was not made public.Premjee, who is majoring in business administration, said that he was detained that same day at the Kappa Sigma fraternity house and was then taken to the Southwest LAPD Office, where he was questioned and later released.Premjee said he could not discuss specifics about the case due to legal reasons. Robinder Samudrala, his attorney, declined repeated requests for comment.Premjee said that he wrote a letter of resignation to the president of the Kappa Sigma fraternity prior to his arrest.“I know incidents like these get fraternities kicked out,” Premjee said. “I didn’t want to put the brothers at risk.”Kappa Sigma President Evan Lubin said that Premjee was suspended from the fraternity following the original incident on April 1.“His actions are absolutely not condoned by the Kappa Sigma Fraternity,” Lubin wrote in an email to the Daily Trojan.Premjee has been charged with a felony, according to LAPD Public Information Officer Tony Im. LAPD Detective Oscar Gamino confirmed that the first preliminary court date regarding the case is set for May 2, and that LAPD still needs to hear from witnesses. LAPD could not comment on the statement or the victim.DPS Assistant Chief David Carlisle said that DPS protocol requires officers to immediately notify LAPD upon receiving any reports of sexual assault. DPS cedes all authority to conduct the investigation to LAPD, providing assistance upon request, Carlisle said.“Once the sexual assault is reported to us, we must notify the LAPD,” Carlisle said. “We would also concurrently notify [the Relationship and Sexual Violence Prevention and Services] and the Office of Title IX so that resources to support the victim are provided. Our primary concern is the safety and well-being of the student. LAPD handles the criminal investigation part.”Premjee said that representatives of the Title IX office at USC have contacted him and would be “glad to help out” if he had trouble navigating the current situation. He added that he has not met with the Office of Student Judicial Affairs and has not been suspended.“I have faith in our justice system, and I hope to be free of these charges very soon,” Premjee said.The Office of Equity and Diversity, Residential Education Office and RSVP were unable to be reached at time of publication.
