Derrick Rose Practices 5on5 For 1st Time In Comeback

Chicago Bulls point guard Derrick Rose, who is recovering from an ACL injury, took a big rehab step on Monday by practicing in 5-on-5 drills for the first time this season.Rose had been cleared by doctors for regular contact for weeks, and had been seen working out the last couple of weeks before games. But Monday gave the All-Star an opportunity to participate in his first scrimmage.“He was able to get out there, and it’s good,” Bulls guard Kirk Hinrich said. “It was something that (we) as a team needed, as far as every individual coming off the (All-Star) break needed to scrimmage a little bit. And I’m sure it was good for (Rose), helpful to … give him a good gauge where he’s at.”The Bulls intentions were to allow Rose to participate in 5-on-5 drills after the All-Star break, and would closely observe how his body would respond, according to Bulls vice president of basketball operations John Paxson.Bulls coach Tom Thibodeau gave short answers to questions about Rose.“He did what everyone else did. Just a normal practice.”Rose made headlines last week, saying he would not come back until he’s “110 percent” and that he would be fine with missing the remainder of 2012-13 season.Last week, the Chicago native said he knew he had not fully recovered because of his inability to dunk the ball. Monday was no different; he was still not dunking, according to teammate Joakim Noah.Rose has been attacking his rehab aggressively. His teammates notice his drive to return, with him being the first one in the gym and the last one to leave.“I would love to (come back this season),” Rose told ESPN in Boston on Feb. 13. “I would love to. That’s why I approached my rehab and my workout so hard. I’m trying to get back on the court as quickly as possible, but if I have anything lingering on, it’s no point.”The Bulls will return to action Tuesday night against the New Orleans Hornets and will look to get a boost from Hinrich, who has missed the last seven games with an elbow infection. They will also look to guard Nate Robinson to continue to give them a spark.But Thibodeau reiterated that Rose will only return when he has fully recovered.“We have to be patient,” Thibodeau said. “When he’s ready, he’ll go.” read more

US energy use chart shows we waste more than half of our

Image credit: Lawrence Livermore National Laboratory and the US Department of Energy. Citation: US energy use chart shows we waste more than half of our energy (2011, April 9) retrieved 18 August 2019 from https://phys.org/news/2011-04-energy_1.html (PhysOrg.com) — This flow chart of the estimated US energy use in 2009, assembled by the Lawrence Livermore National Laboratory (LLNL), paints a pretty sobering picture of our energy situation. To begin with, it shows that more than half (58%) of the total energy produced in the US is wasted due to inefficiencies, such as waste heat from power plants, vehicles, and light bulbs. In other words, the US has an energy efficiency of 42%. And, despite the numerous reports of progress in solar, wind, and geothermal energy, those three energy sources combined provide just 1.2% of our total energy production. The vast majority of our energy still comes from petroleum (37%), natural gas (25%), and coal (21%). That percentage of oil illustrates that by far our biggest problem – or area of improvement – is transportation. As the chart shows, the transportation sector is the single biggest consumer of energy, accounting for nearly 40% of the energy consumed by the four sectors (along with residential, commercial, and industrial). In comparison, just 16% is used for residential use. And while the residential, commercial, and industrial sectors waste about 20% of their energy, the transportation sector wastes a full 75%, making it just 25% energy-efficient. Part of this waste is due to the fact that cars are an inherently inefficient way to move people around, since much of the energy must go into moving the massive car and not simply the person.The chart emphasizes the importance of using alternative methods of transportation – walking, biking, public transportation, or anything else that moves more human and less steel. Unfortunately, due to developers building sprawling suburbs to satisfy Americans’ demands of large homes and yards, many people now find themselves miles from the nearest grocery store and have no choice but to drive everywhere. To illustrate how transportation consumption and waste dwarfs residential consumption, a blog post on Treehugger notes that “building suburbs of Energy Star houses with solar panels on top is a complete waste of time.”With that being said, comparing the 2009 chart to the 2008 chart shows that we’re making progress. The total amount of solar energy production increased from 0.09 to 0.11 quads, wind energy increased from 0.51 to 0.70 quads, and geothermal increased from 0.35 to 0.37 quads. (The amount of energy in one quad is equivalent to that produced by the burning of 36 million tonnes of coal.) Overall, the US consumed less total energy in 2009 (94.6 quads) than in 2008 (99.2 quads) as well as any year back to 1999 (97 quads), which is the first year for which LLNL has a chart on its website. There were even three years during the past decade when the country consumed more than 100 quads. In addition, the total waste in 2008 was 57.07 quads, compared to 54.64 quads in 2009 (though the percentage wasted was about the same).Although there is vast room for improvement, if the US can employ a combination of decreasing consumption, increasing efficiency, and increasing the role of renewable energy sources, hopefully we’ll continue heading in the right direction.
