New Livestock Effort Will Protect Animals From Abuse

first_imgProducers and consumers can get more information about See it? Stop it! at SeeitStopit.org.   The program stresses that consumers have the right to expect that animals raised for food are raised humanely. Although it is uncommon on farms, when animal abuse, neglect, harm or mishandling takes place, anyone who witnesses the act has an obligation to speak up. Farmers participating in the See it? Stop it! initiative provide their employees with education and promote the importance of proper and responsible animal care. In addition, they encourage and enable employees to immediately report any sign of animal abuse, neglect, harm, or mishandling. This program gives farmers a way to provide assurance to consumers that they are doing the right thing. In fact, as a condition of employment, many pork operations require workers to sign policy documents that confirm their roles and responsibilities for animal care, including the reporting of any animal abuse they witness. Such policies usually include disciplinary action, including termination, for failure to report abuse. The initiative is an adjunct to the pork industry’s We Care program, which promotes pork producers’ long-standing commitment to responsible pork production and to continuous improvement in animal care, handling and transportation. It also bolsters the Pork Quality Assurance® (PQA) Plus® program, which outlines best practices for proper animal care, and the Transport Quality Assurance program, which certifies people who transport hogs in proper care and handling methods. By Gary Truitt – Apr 1, 2013 Facebook Twitter Facebook Twitter Home News Feed New Livestock Effort Will Protect Animals From Abuse Josh Tranery with Indiana Pork says this kind of a system will not only do a better job of protecting animals, but also protect producers from exploitation from misleading images given to radical animal activist groups, “We need to stop animal abuse, but not allow misleading images and reports to damage the entire industry.” Legislation currently before the Indiana House would prevent unauthorized photography and video images of farming operations from being made public and require that such images or complaints of animal abuse be reported to proper authorities within 48 hours.   SB373 along with See it? Stop it! would provide a fast and credible reporting system that would protect animals from abuse while protecting farming operations from exploitation by activist groups and the media. To date, groups that have signed onto the program include the National Pork Board, National Pork Producers Council, National Milk Producers Federation, the Center for Food Integrity, and the National Dairy Farm Program.   This is the first time that different species groups have joined forces on the animal care issue. “Pigs and cows are not the same so there are not many things we can collaborate on, but See it? Stop it! is one things we can all agree on,” said Neikamp. SHARE New Livestock Effort Will Protect Animals From AbuseTwo livestock groups have come together to launch a program aimed at stopping animal abuse and reassuring consumers that all is well on the farm. The program is called See it? Stop it!, and it is the first of its kind to empower all who work with animals to be on the lookout for animal abuse.  Sherrie Neikamp, Pork Checkoff director of animal welfare, said the pork and dairy industry have joined forces to make sure any case of animal abuse or neglect is reported quickly and to the proper authorities, “Animal abuse is absolutely unacceptable and will not be tolerated.” The guidelines of the program state that animal care is the responsibility of everyone who works with animals , “Individuals who work around animals have an obligation to immediately report any signs of deliberate animal abuse or neglect.”  “Animal well-being always has been the top priority of pork producers,” said NPPC President Randy Spronk, a producer from Edgerton, MN. “The See It? Stop It! initiative confirms that commitment and is a way to let animal caretakers know that it’s their moral responsibility to speak up to stop any animal abuse.” The voluntary program encourages farm employees to report cases of animal abuse to the proper authorities and requires farmers who participate in the program to set up an alert system to provide for the timely reporting of any animal mistreatment. According to the See it? Stop it! web site, “The initiative encourages and empowers individuals working with or around animals to immediately report any signs of deliberate animal abuse, neglect, harm or mishandling to a supervisor or other individual responsible for enforcement of proper animal care, to ensure the concern is heard and addressed.”  Farmers and farm managers are required by the program to: Provide accessible and reliable contacts that have immediate authority to address reports of animal care concerns; Take swift action to correct all instances of inappropriate animal care; Ensure employees who raise concerns in good faith are not penalized. Neikamp says producers can learn more about the guidelines of the program and download materials by visiting the special web site, “They can even download posters that can be place in barns to provide employees with proper contact information to report abuse.” SHARE New Livestock Effort Will Protect Animals From Abuse Previous articleEnvironmental Groups, Beekeepers File Lawsuit To Cancel Seed Treatment RegistrationsNext articleA Good Year to Secure that Nitrogen Gary Truittlast_img read more

Pasadena School Board to Hear Plans for ‘Controversial’ Solar Power Plan

first_img Name (required)  Mail (required) (not be published)  Website  Community News Business News Pasadena Will Allow Vaccinated People to Go Without Masks in Most Settings Starting on Tuesday Subscribe Plans for a “controversial” District-wide PUSD solar power project will be heard by the Board of Education Thursday.According to a PUSD agenda report, the project envisions district power expenditure savings of up to $17 million over the length of the 25-year contract.“It’s such a long-term commitment,” said Board member Scott Phelps Wednesday. “It’s such an unknown, I guess that’s why it’s controversial. We don’t know what the power rate will be. We’re doing it because there’s an estimate that they will increase, and so we locked in lower rates.”PUSD signed a Power Purchase Agreement (PPA) with PFMG Solar in 2018 for construction and operation of the PUSD solar project. PFMG has since been sold to Constellation, a subsidiary of Exelon, which owns six utility companies across the US.Under the PPA, PUSD will not spend any funds from project inception to completion; additionally, there will be no maintenance costs for the next 25 years.The school district shall pay a reduced rate of energy costs, approximately $.05 or less per kilowatt-hour. Over 60 percent of PUSD’s electricity requirements can be supplied by solar power, resulting in large power savings, the PUSD said.According to spokesperson Dave Snyder of Constellation, the rate is 5 cents per kW/h less than they would otherwise pay if they were purchasing energy from the utility.Phelps added, “We just don’t know what will happen over 25 years. Long-term power contracts remind me too much of what happened to the State of California during the games Enron and others were playing.”According to a January 2020 U.S. Energy Information Administration (EIA) report, “The EIA expects that wholesale electricity prices in many areas of the country in 2020 will be lower than last year, reflecting the lower costs for natural gas as a fuel for power generation.”The report also forecast that wholesale prices in the Southwest will rise 5% in 2020, as a result of the recent retirement of some coal-fired generating units. In 2021, EIA expects that “wholesale power prices will increase in most areas, as a result of an expected 9% increase in the cost of natural gas.”EIA also forecast that the U.S. retail price for the residential sector will average 1 cents/KWhh (kilowatt hours) in 2020, which is 1.2% higher than the average retail price in 2019. Forecast residential prices will increase by an additional 1.2% in 2021, said the report.Phelps said he didn’t know whether or not the agreement was a “bad idea.”“I just don’t like a lack of flexibility,” he said, adding, “Then again, we have to pay whatever we are charged now by Pasadena Department of Water and Power and Edison so maybe it’s not any worse.”According to Phelps, a number of Southern California school districts have solar panels in parking lots. Those districts may have purchased the equipment with school bonds, he said.According to the District agenda report, construction of the solar panels under Phase 1 is slated to begin this month, at no cost to PUSD nor to the City of Pasadena. The first phase will include installation at Coombs Elementary School, John Muir HS, Cleveland ES, Don Benito FS, Hamilton ES, and McKinley, with completion expected by the end of June.The second phase of the project, will begin construction in February, with completion expected around July or August. Phase 2 will include installation work at Rose City High School, Field ES, Longfellow ES, Madison ES, Sierra Madre MS, Washington STEAM, and Blair HS. Completion of Phase 2 is expected in July or August.Phase 3 and Phase 4 of the project begin construction later, with the latest completion date around December 2020. In all, 28 PUSD campuses will have solar power plants, upon the completion of the project.The Board of Education meeting begins at 4:30 p.m. at PUSD Headquarters, at 351 S. Hudson Ave., Pasadena.

Report finds 211GW of U.S. coal generation under serious economic threat

first_imgReport finds 211GW of U.S. coal generation under serious economic threat FacebookTwitterLinkedInEmailPrint分享CNN Business:The simple laws of economics threaten to doom America’s remaining coal power plants.Wind and solar costs have plunged so rapidly that 74% of the U.S. coal fleet could be phased out for renewable energy — and still save customers money, according to a report released on Monday by Energy Innovation, a nonpartisan think tank. That figure of at-risk coal plants in the United States rises to 86% by 2025 as solar and wind costs continue to plunge.The research demonstrates how it’s increasingly more expensive to operate existing coal plants than build clean energy alternatives.“U.S. coal plants are in more danger than ever before,” Mike O’Boyle, director of electricity policy at Energy Innovation, told CNN Business. “Nearly three-quarters of U.S. coal plants are already ‘zombie coal,’ or the walking dead.”The Energy Innovation report found that in 2018, 211 gigawatts of existing U.S. coal capacity — or 74% of America’s fleet — was at risk from local wind or solar that could more cheaply churn out just as much electricity.North Carolina, Florida, Georgia and Texas are the U.S. states that have the greatest amount of coal plants at risk from local solar and wind, the analysis found. Energy Innovation defined local as within 35 miles. By 2025, Midwestern states including Indiana, Michigan, Ohio and Wisconsin are expected to have high amounts of coal capacity under pressure from renewable energy.More: Most of America’s coal plants are more expensive than wind and solarlast_img read more

Is a Ground-Source Heat Pump the Right Choice?

first_imgIn Grand Rapids, Michigan, Andy Zbojniewicz is planning a large, high-performance home that ultimately will be powered by a 15-kW solar array. The house will have more than 3,000 square feet above grade, and another 1,633 square feet in the basement. His immediate concern is how to heat and cool the house. “I was told the home was too large to heat and cool with air-source heat pumps and be comfortable,” Zbojniewicz writes in a Q&A post,  “so [I] was primarily looking at geothermal.”RELATED ARTICLESDucted Air-Source Heat Pumps from American ManufacturersGround-Source Heat Pumps Don’t Save EnergyAir-Source or Ground-Source Heat Pump?Are Affordable Ground-Source Heat Pumps On the Horizon?All About Radiant Floors To that end, Zbojniewicz sought quotes from two HVAC contractors for ground-source heat pumps. One of the contractors said the heating load would be 50,797 Btu per hour at an outside temperature (design temperature) of 7°F, and recommended a 5-ton (60,000 Btu/h) heat pump. The second company didn’t provide its load calculations, but suggested that Zbojniewicz would need two 3-ton heat pumps in order to stay comfortable. “I have a friend who is in HVAC and he feels strongly that I should have radiant tubing run in the basement to help with heating in winter,” Zbojniewicz adds, “and while I was at it I was going to run it in the mudroom, master bath, and three-season porch.” After doing some reading at GBA, Zbojniewicz realizes there are plenty of critics of both ground-source heat pumps and radiant-floor distribution systems. “Is there a better alternative to geothermal if I want to have the potential for net zero?” he asks. “If I stick with geothermal, are two 3- ton heat pumps overkill (they’re certainly more expensive)? Should I abort the radiant altogether?” That’s the topic for this Q&A Spotlight. There is nothing wrong with air-source heat pumps The outside design temperature for Grand Rapids, Michigan, is 5° or 6°F, GBA Editor Martin Holladay says, so Zbojniewicz can certainly consider air-source heat pumps. A heat pump from a U.S. manufacturer paired with a conventional forced-air duct system would be fine. Holladay suggests that Zbojniewicz read a GBA article, “Ducted Air-Source Heat Pumps from American Manufacturers.” Dana Dorsett adds, “I’m aware of a house in Vermont slightly larger than yours and slightly less insulated, in a location with a 99% outside design temp of -12°F that is heated with four ductless mini-splits. The notion that your house is ‘too large’ to heat with a heat pump is just silly. It’s the size of the heat load, not the house, that matters.” There are some pluses to a ground-source system Jon R contends that radiant heat paired with a ground-source heat pump is great — as long as Zbojniewicz doesn’t care about how much the system costs. Such a system not only provides space heating but also provides efficient water heating. “If you are looking at air-to-water geo-exchange, then you can add a water tank (thermal mass), resolving any heat pump over-sizing issue other than cost,” Jon R adds. “If very large, it can enable some use of solar PV that doesn’t involve net metering. Multi-stage or multiple heat pumps also mitigate over-sizing.” Those load calculations are probably wrong The capacity of any system that Zbojniewicz installs should be based on two factors: the climate, and how well the house is air sealed and insulated. And Dorsett doesn’t have much confidence in the heat load estimates that one of Zbojniewicz’s contractors has provided. “Don’t believe the 50K heat loss number unless it was done by a qualified third party,” Dorsett writes, “an engineer, RESNET rater etc.,  somebody who makes their living and reputation on the accuracy of their numbers rather than installing and maintaining HVAC equipment.” Even a code-minimum house of that size with a measured air tightness of 3 ach50 would have a heat load of less than 40,000 Btu per hour, he says, assuming an outdoor temperature of 0°. “The only way to stretch it to 50K would be to have excessive air leakage or excessive expanses of window area,” Dorsett says. “Your house is likely to come in closer 30K @ 0F, 36K tops and even less at +7F.” With that in mind, a heat pump with a capacity of 60,000 Btu/hour is about twice the size that Zbojniewicz really needs. The place to start, Dorsett says, is a Manual J heat load calculation, and it’s his bet that two modulating Fujitsu minisplits or possibly a 3-ton Carrier Infinity Greenspeed air-source heat pump with heating strips would keep the family comfortable. Steve Theinalienable’s experience bears that out. “My house insulation, climate, windows, and foundation insulation are almost exactly the same as yours, just a bit smaller (2200 square feet),” he says. “My design heat load at -18°C [roughly 0°F] is 18K Btu, but we had a day like that this week, and my air-source heat pump didn’t have to work that hard to keep up, so, I think it’s probably a bit conservative.” Get your house rated by a pro, Theinalienable says. Consider the all-electric option With a tight building envelope and a relative large photovoltaic system, why not consider an all-electric house? asks Armando Cobo. “I would highly advise you to consider going all-electric with an air-to-air heat pump, and hopefully installing [Energy Star] appliances and lighting, electric fireplaces and an induction cooktop,” he says. “That’s what I spec on all my houses, which are [zero energy ready homes]. Just a thought!” In fact, Zbojniewicz is trying to convince his wife that an electric fireplace and induction cooktop are good choices. Zephyr7 suggests he invest $50 or $60 in a portable, one-burner induction cooktop and experiment with it. “Have your wife play around with it,” he says. “It’s an inexpensive way to test out induction cooking. Note that not all pots are compatible with induction cooking.” Insulating the rim joist One footnote to Zbojniewicz’s efforts to obtain more accurate heat load estimates involves insulation. He’s found a company that will do Manual J calculations, but he’s not sure how to specify the insulation he will use at the rim joist. What’s the best approach? “Closed-cell [spray foam] is pretty standard for use on rim joists,” replies Zephyr7. “Lots of people use kits like those from Foam it Green and the Dow Froth-Pak. What you want to avoid is keeping the wood wet. Your assembly sounds like it won’t be a problem, but make sure you have a capillary break between the rim joist and the top of the foundation wall.” Cobo says open-cell foam is best at the rim joist when rigid foam will be applied to the outside of the wall. Because Zbojniewicz is planning to use Rockwool on the outside of the house, either open- or closed-cell foam can be used, he adds. Holladay suggests he choose closed-cell foam, not open-cell foam. “In a cold climate, closed-cell spray foam would be a better choice for the interior of a rim joist,” he says. “You’re right that either type of spray foam is an air barrier. The reason that closed-cell spray foam is better is because it is a vapor barrier, unlike open-cell spray foam. The closed-cell spray foam prevents outward diffusion of water vapor, and therefore keeps the rim joist dryer.” Our expert weighs in Peter Yost, GBA’s technical director, adds this: Cold-climate heat pumps: It is interesting to hear the misgivings that air-source heat pumps will be unable to manage either larger homes and/or cold climates. I was just in Wisconsin recently and heard the same litany. Dana Dorsett, as usual, is right on: Heating loads are assessed using U-factors and building enclosure surface areas (and other metrics, including airtightness), not square feet of living or conditioned space. In the Northeast, heat pumps designed to wring out BTUs at air temperatures well below 0°F have proven efficient and reliable. Marc Rosenbaum, a leading and inherently skeptical mechanical engineer, has helped spread the word by recounting his own great success with cold-climate air-source heat pumps. We did have problematic cold-climate heat pumps in the past (both Nyle and the Hallowell cold climate heat pumps had problems and went out of business some 10 years ago) and that news seems to persist. The technology of today’s cold-climate heat pumps is very different and has proven to be robust. (See numerous GBA resources on the topic, including this one.) Radiant-floor heating. We just can’t seem to get our arms around the pros and cons of this method of heat distribution. It is not more efficient. There is nothing magical about radiant-floor heat. Its efficiency is driven by the same physics that governs all other distribution systems. And part of the physics is the mass to which the distribution system is connected. It’s very difficult if not impossible to gain efficiency by way of thermostat setback. It is more comfortable. It’s hard to argue with this, either empirically or based on heat transfer. In my experience, well-designed and installed radiant floor heating systems deliver superior thermal comfort. Radiant-floor distribution can be used for space cooling. As Robert Bean has said more times than he cares to count: We keep blaming condensation during cooling on the radiant system when, if the latent load were properly managed, radiant cooling can work just fine (for more, see this). Insulating the rim joist: In my experience, rim joists get wet from backsplash at grade from the exterior or, less commonly, wicking because there is no capillary break between the mudsill (or sill beam) and the foundation wall. In cold climates, I don’t see rim joists getting wet from air leakage because the stack effect is pulling cold dry air in during the winter at the rim joist. So, the main reason for me to choose open- or closed-cell spray foam at the rim joist — since both can provide a good air seal at this location — is based on how much drying potential I need to the interior (open-cell spray foam being more vapor-permeable than closed-cell). Manual J: It’s really heartbreaking to hear how often heat-load calculations are not done. Can you imagine a car company designing a transmission system without knowing the horsepower and torque the engine can generate? On the other hand, it’s heartening to see how often the general public ends up on GBA’s Q&A pages to work with leading building professionals on home performance.last_img read more

Ind vs Eng: Reports of Team snub to envoy baseless, says BCCI

first_imgThe Board of Control for Cricket in India (BCCI) on Wednesday called reports of Team India missing the Indian High Commissioner to UK, Nalin Surie’s reception for the players as “baseless”.In a media release, the BCCI clarified its stand saying that the team had committed itself for “another function on the same day, six months in advance”. “The BCCI had accordingly communicated the same to the Indian High Commission, and suggested that the reception be organised on 25 July 2011 instead.””However, the Indian High Commission authorities said that there were other engagements scheduled on the 25th. They also informed the BCCI that they would get in touch with the Indian team management after its arrival in the UK, and fix up a date for the reception. The BCCI agreed to this,” the release added.Meanwhile, in a face-saving measure, the BCCI has drafted its team manager Anirudh Chaudhry to hold talks with the officials of the Indian High Commission and it is learnt that the reception may be organised in August, when the Indian team returns to London.last_img read more
