Rising air conditioning demand threatens to overturn India’s renewables goals

first_img FacebookTwitterLinkedInEmailPrint分享The Economic Times:The growth trajectory of the cooling industry, particularly air conditioning, can become a major roadblock in India’s energy transition to renewables by 2030, according to a study by The Energy and Resources Institute (TERI).The air conditioning sector is expected to grow at around 10 percent which may present a huge challenge for the integration of renewables in the energy system because much of the country’s residential cooling demand falls at night when solar is not available, it said.“The growth trajectory of cooling, in particular air conditioning, is expected to be particularly rapid, at about 10 per cent per year,” the research paper titled “Understanding India’s electricity sector transition to renewables” said.India’s electricity demand is projected to grow at 6 per cent per year between now and 2030, reaching about 2040 trillion watt hour (TWh) of grid-based electricity demand. Taking into account the projected transmission and distribution (T&D) losses and auto-consumption, national generation requirements would be on the order of 2400 TWh.This growth rate in itself presents a challenge to substantially increase the share of renewables, requiring an extremely rapid rate of capacity addition to meet incremental demand growth.“Scenarios studying the grid integration of renewables clearly show that the need for power system flexibility is projected to grow significantly under ambitious scenarios for the increase in renewables,” said the paper.While total demand is projected to double by 2030, the need for daily balancing which is shifting energy within a day to balance the variability in solar output, is also projected to grow six-fold by 2030. The available supply of flexibility is expected to exceed by the mid-2020s, posing an absolute constraint on the growth of renewables, unless proactive measures are taken to increase the flexibility of the power system.An analysis of the grid integration challenge of variable renewables in India clearly show that this transformation will be unachievable unless substantial progress is made in developing a comprehensive portfolio of flexibility options.More: India’s energy transition to renewables: Air conditioning to pose a key challenge Rising air conditioning demand threatens to overturn India’s renewables goalslast_img read more

Colin The Steeler circus is on Mike Tomlin

first_imgThe Steelers have long been one of the most stable franchises in the NFL, but the team has become a circus with Antonio Brown discussing being traded on Twitter, and the team struggling in the first two weeks of the season with an 0-1-1 record. Last season, Ben Roethlisberger publicly questioned Tomlin in the media over the team’s lack of discipline.Colin thinks Mike Tomlin is a good coach, but his loose, player friendly culture is the root cause of the growing dysfunction.When Tomlin was hired, he rode the momentum from the Bill Cowher era to two Super Bowl appearances and a championship, but the team has progressively declined, especially in the playoffs, in the last several years as the momentum has dissipated.Now the circus is in town, and it’s on Tomlin.“As the momentum of Cowher has dissipated and it’s now Mike Tomlin’s team, the offensive stars are calling out Tomlin because his side of the ball isn’t working.”@ColinCowherd on the “circus” surrounding the Steelers pic.twitter.com/4bbXt1e9uj— Herd w/Colin Cowherd (@TheHerd) September 19, 2018last_img read more
