LEAVE A REPLY Cancel replyLog in to leave a comment British R&B is having a moment.More than ever, young artists from the other side of the Atlantic are pushing the genre forward and keeping it exciting.Nao, Jorja Smith, Mabel, Raleigh Ritchie and Ray BLK are all carving out distinct sounds and spaces in the London scene. Its eclectic and progressive energy allows it to rival mainstream North American R&B and soul. Twitter While Toronto’s scene has all the pieces to become its own mecca of R&B, it could take some notes from the British.The aforementioned UK artists are sonically diverse, whereas Toronto’s use more homogenous production styles. Woozy electronic beats, heavy bass and resonant 808s have become the official sound of Toronto R&B, and very few budding artists stray from this formula.In contrast, Nao, the patron saint of neo-soul, sounds nothing like Ray Blk, whose candid, stripped-back style sounds nothing like the haunting, lingering melodies of Jorja Smith.There are outliers in the local scene whose production and lyrics deviate from the norm, but they’re not earning the same recognition as musicians like the Weeknd, PartyNextDoor and dvsn.TiKA, who recently opened for Nao at the Phoenix, is one of these artists. Along with local acts Jessie Reyez, Charlotte Day Wilson, McCallaman, Unbuttoned, M.I.Blue and Daniel Caesar, she taps into soul music’s emotional vulnerability.READ MORE Login/Register With: Facebook Advertisement Advertisement Advertisement
That makes electricity different from most industries. Just imagine what would happen if automakers had to do this. The moment you bought a car, a worker would have to drive it out the factory gate. Assembly lines would constantly speed up and slow down based on consumer whims.It sounds maddening and ridiculous, right? But electric grid operators basically pull this off, balancing supply and demand every few seconds by turning power plants on and off. That’s why a storage boom would make a big difference. Storage creates the equivalent of a warehouse to stow electricity when it is plentiful for other times when it is needed. This article was originally published on The Conversation. Read the original article. The U.S. Energy Department’s SunShot Initiative aims to reduce the cost of solar energy and to make it easier to deploy. Stretching powerEnergy storage can help in a variety of ways, essentially serving as a Swiss Army knife for electricity grids. It can help balance short-term power fluctuations, manage peak demand or act as a backup to prevent or recover from power outages.And it can be deployed at any scale and at any point in the grid, from a small home storage system to a pumped hydroelectric reservoir big enough to power a small city. While storage actually consumes a little electricity rather than producing any, it makes the electricity business more economically efficient. As the volume of storage grows, we expect grids to become more stable and flexible. Storage may also make a big difference with electricity generated through solar or wind power – which can only be harnessed when the sun is shining and the wind is blowing. But, in general, it isn’t necessary for that purpose yet. While those industries are growing quickly, wind power generates only about 6 percent of U.S. electricity and solar less than 2 percent. Electricity grids can currently use almost all of that power as it is produced.Grid operators, accustomed to managing the variable supply and demand for power, can manage the extra unpredictability they get from wind and solar energy now. But as utilities, businesses and consumers bring more renewable energy online, the grid may become harder to balance without additional storage.To be sure, hydroelectric plant operators have been storing power for a long time. The U.S. has the capacity to store some 22 gigawatts in pumped hydropower, about 2 percent of U.S. generating capacity. Yet its reliance on large water reservoirs, which can’t be easily constructed near power markets, limits the growth potential of this energy option. Competing with natural gasOnce energy storage scales up, utilities will meet peak demand more easily with less total capacity and fewer power plants. If they can rely on storage to supply power during high-demand hours instead of building new power plants, it can save money all around.But storage isn’t the only game in town – other technologies offer similar benefits. Utilities can install new transmission lines or rely on flexible natural gas, which is essentially the biggest competitor for energy storage.Natural gas generation produces about a third of the nation’s electricity today and provides many of the same benefits as storage since these power plants are easy to switch on and off. The relatively low prices for natural gas, less than half of what they were a decade ago due to widespread hydrofracking, have probably slowed energy storage growth until now. Natural gas has become increasingly popular for power generation, displacing demand for coal since 2000. But if storage gets cheap enough, this equation may flip and storage could threaten the economics of natural gas generation. The market for energy storage on the power grid is growing at a rapid clip, driven by declining prices and supportive government policies. Explore further Help from the government and better batteriesOne reason why this industry is growing is that it’s getting a boost from the government.California, Maryland, New Jersey and Nevada are subsidizing storage, mandating its adoption or both. A similar measure is pending in Hawaii’s legislature.And despite the Trump administration’s efforts to maximize fossil fuel extraction, the federal government is now laying the regulatory groundwork for the storage industry to compete directly in open wholesale energy markets for the first time. Improvements in technology have made a difference, too. Battery technology, led by the same lithium-ion design that powers mobile phones, is making big strides and getting much cheaper. Lithium-ion batteries are both responsible for most of this new wave of grid-connected energy storage and the critical component inside the rapidly growing number of American electric vehicles. For example, the lithium-ion battery used in the the Tesla Powerwall, a home battery system, is the same as the one the company uses in its vehicles.Grid-scale lithium batteries often differ from those in cars but use the same basic technology. The price of utility-scale lithium-ion battery systems fell 40 percent in just five years to around US$1,200 per kilowatt-hour in 2015 from roughly $2,100 in 2010 and are expected to continue falling. The futureThe grid currently has relatively little storage for the same reason that only about 200,000 of the 17.2 million vehicles Americans bought in 2017 were electric: It’s expensive today. Electric vehicles do not yet save money for most U.S. drivers. But market experts project that electric vehicles ownership will cost less than standard vehicles powered by gasoline within a decade and continue getting cheaper after that.Likewise, for the electricity grid, if storage gets cheap enough, its potential market could expand from 1 gigawatt-hour to dozens or even hundreds of gigawatt-hours. If or when that happens, wind and solar power would become more competitive, increasingly displacing both coal and natural gas – now the nation’s two top sources of electric power. And this cheaper storage would also make electric vehicles more affordable, reducing the amount of gasoline and diesel Americans consume. The electricity and automotive industries operate nearly the same way they did 50 years ago. But a world of low-cost batteries would change them both in exciting and unprecedented ways.No matter what happens, we believe that storage is “future-proof” because it works well on the current grid and with a wide variety of other technologies. If the wind and solar industries keep up their current momentum (and they probably will), storage will become even more valuable. But if the grid goes another direction – relying more on large and expensive generation plants, for example – storage would make it easier to manage peak demand without surplus capacity. Even if we can’t say exactly what the grid of the future will look like, we are pretty confident that storage will keep it humming in new ways. This document is subject to copyright.

It’s like having a bunch of rechargeable batteries, but much larger than the ones in your cellphone and probably connected to the grid. After annual average growth of about 50 percent for five years, the U.S. electricity industry installed a total of 1 gigawatt-hour of new storage capacity between 2013 and 2017, according to the firm GTM Research. That’s enough to power 16 million laptops for several hours. While this amount of storage is less than 0.2 percent of the average amount of electricity the U.S. consumes, analysts predict that installations will double between 2017 and 2018 and then keep expanding rapidly in the U.S. and around the world. To see why this trend is a big deal, consider how electricity works.It takes a hidden world of complexity and a series of delicate balancing acts to power homes and workplaces because the grid has historically had little storage capacity. After being generated at power plants, electricity usually travels down power lines at the speed of light and most of it is consumed immediately.Without the means to store electricity, utilities have to produce just enough to meet demand around the clock, including peak hours.
Mumbai/Bengaluru: The disgruntled Congress MLAs on Thursday said they would tender their resignation to the Assembly Speaker afresh, in accordance with the Supreme Court order.Insisting they were still in Congress and have resigned only from the Assembly, the MLAs ruled out BJP’s role in the entire episode. “According to the Supreme Court directive, we will reach Bengaluru and meet the honourable speaker. Since the Apex court has directed us to tender resignations afresh, we are going there. There is no change (in our decision),” BA Basavaraja, Congress MLA from KR Puram in Bengaluru told reporters in Mumbai.He rubbished allegations that the saffron party was behind the spate of resignations that threatened the existence of the coalition government and that the BJP-led government in Maharashtra was aiding them.”Allegations have been made that the BJP government in Maharashtra is with us. We want to clarify that neither the BJP nor any other government is with us. But we have sought protection from the government, which they have provided. There is no BJP role in it,” Basavaraja said.Yashwantpur Congress MLA S T Somashekhar echoed similar views in Bengaluru.”The speaker has given us in writing that it (resignation) is not in a proper format. Hence, we will submit our resignation in the proper format before 6 pm,” the MLA told reporters.Somashekhar too insisted that he was very much in the Congress and has only resigned from the assembly.”I am still in Congress…. for our personal reasons, we have submitted our resignations, he said adding “We haven’t switched to any other political party.”Welcoming the apex court order, Somashekhar said he would meet the Speaker and tender his resignation afresh before 6 pm.The Supreme Court Thursday allowed the 10 rebel MLAs of the Congress-JD(S) coalition in Karnataka to meet the assembly Speaker at 6 pm to convey to him their decision to resign.The bench headed by Chief Justice Ranjan Gogoi asked the Karnataka Assembly Speaker to decide on the resignation of the MLAs during the course of the day and intimate the court on Friday about the decision taken by him.The court stated that the order pertained only to 10 MLAs who had petitioned and not the six others.If the 10 resignations are accepted, the number of MLAs in the ruling camp would get reduced to 106 sans the Speaker, while the BJP presently has 107 MLAs on its side.The halfway mark is 113 in the 224-member Assembly. congressJD(S)karnatakaKarnataka Assembly First Published: July 11, 2019, 4:00 PM IST
In a blog post on Monday, Waymo CEO John Krafcik revealed that one of the company’s self-driving vehicles has been involved in an accident with a motorcycle. The “manual collision” happened in Mountain View, California, on El Camino Real, and was the result of an attempt to avoid a different anticipated wreck, according to the company. The car was not operating itself at the time of the accident. According to details the company provided on Medium, the self-driving Waymo vehicle was operating on the road with a safety driver. That driver saw a car to their left “abruptly move towards” the Waymo car. To avoid being hit by that vehicle, the Waymo driver took control and moved the car into the right lane.However, “a motorcyclist had just moved from behind our vehicle into the right lane to pass us,” according to Waymo, and its driver failed to notice the motorcycle. This resulted in the Waymo car striking the motorcycle with its right rear bumper; the motorcyclist is described as “injured.”Despite training, Waymo points out that its safety drivers may still be presented with some scenarios that “challenge human drivers.” Krafcik explained in his post:AdChoices广告People are often called upon to make split second decisions with insufficient context. In this case, our test driver reacted quickly to avoid what he thought would be a collision, but his response contributed to another.Incidents like this are what motivate all of us at Waymo to work diligently and safely to bring our technology to roads, because this is the type of situation self-driving vehicles can prevent. A copy of the vehicle accident report is available from the California DMV here.SOURCE: Waymo (Medium)
