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 goals

For some reason I started thinking about David Johnson the other day. David was an athlete of mine when I taught at Whitewater High School in the mid 60’s. David came to Whitewater from another school system when he was a freshman. He didn’t know anybody so he joined the cross country team to feel that he was a part of his new school. Before it was over, David became an excellent runner and this let him go to college on a partial athletic scholarship. Besides the love for running, David also liked the outdoors. His college education allowed him to be a park ranger.David moved to Alaska to pursue his love for the outdoors. Before his untimely death of a heart attack, David started a marathon in his adopted state of Alaska. If you have a son/daughter who moves to a new school system as David did, make sure they find some activity that allows them to become involved and make new friends. David became one of the most popular students at Whitewater because he took a chance and came out for cross country.
Hotel tycoon Surinder Arora is suing the Heathrow Airport over a planned multi-level car parking, The Sunday Times reported.Arora, who is based in the United Kingdom, plans to construct a 2,077-space, nine-level car park on the piece of land that he owns at Heathrow. He has issued a UK High Court claim against the airport over his plans.The airport has, however, objected to Arora’s project, with the Heathrow Airport Limited claiming that it alone is authorized to construct these spaces. Arora, on the other hand, has said that the cap of 42,000 car park space refers to the airport site as a whole, and his land is a part of this. So this gives him too the right to build car-park spaces, according to the report.Heathrow thinks that Arora should finish the process of planning before he goes to the court. “We believe this is entirely without merit and will respond accordingly,” the airport stated regarding the High Court claim filed by Arora, the report added.According to the local planning rules, a maximum of 42,000 car parking spaces are permitted at the airport. Arora was earlier permitted to build a smaller version with 1,000 spaces and five floors on the site, which opened last year.He now wishes to add another four more floors, resulting in reduction of parking charges at Heathrow, which are currently among the costliest in the world, as per the publication.The row between Heathrow and Arora is more than just about car parking. Arora is using it to bring forth a bigger fight with the airport over whether competition should be allowed, the publication reported.Arora, the founder and chairman of the Arora Group, arrived in the United Kingdom from India as a teenager. He founded the business in 1999 and runs a luxury four-star hotel at Heathrow for airline staff. His estimated net worth now is around £350 million.Arora has also been seeking the right to build a third runway at the Heathrow Airport. He is being supported by airlines including the British Airways, but Heathrow has claimed that the right to develop the runway lies with it.The plan for the third runway recently received the backing of the Cabinet. The plans for a new runway at Heathrow Airport at an expense of £14 billion could be voted on before UK parliament breaks for the summer recess, City A.M. reported.
