General view of the debris of the Ukraine International Airlines, flight PS752, Boeing 737-800 plane that crashed after takeoff from Imam Khomeini airport, on the outskirts of Tehran, Iran on Jan. 8, is seen in this screen grab obtained from a social media video. VIA REUTERS DUBAI – Iran said on Saturday itunintentionally shot down a Ukrainian passenger plane, killing 176 people onboard due to human error. Tehran added it could ask Russia,Canada, France, or Ukraine for help. Wednesday’s crash heightenedinternational pressure on Iran after months of friction with the United States(US). Washington killed an Iranian general last week in Iraq, prompting Tehranto fire at US targets. Iranian Foreign Minister MohammadJavad Zarif said the armed forces investigation showed the downing of theBoeing 737-800 was the result of “human error at time of crisis caused by USadventurism (that) led to disaster.” Iran on Thursday said it woulddownload the information from voice and flight data recorders, known as blackboxes, to determine what happened. Ukraine had been looking at variouspossible causes of the crash, including an attack by a Russian-made missile, acollision, an engine explosion, or terrorism.(Reuters) The US and Canada, which had 57citizens on board, had blamed an Iranian action for bringing down the aircraft.

ALAMEDA — Raiders general manager Mike Mayock has spent the last 15 years as an NFL Network analyst specializing in the NFL draft.His true feelings about prospects will from now on be tied to the Raiders, rather than the NFL Network. His opinions regarding college talent have been on display in public either on the air, through conference calls with the media or on NFL.com web content.Although it’s unreasonable to expect Mayock to be so forthcoming when he’s working for a specific team, …
Share Facebook Twitter Google + LinkedIn Pinterest The Ohio Corn & Wheat Growers Association (OCWGA) and the Ohio Soybean Association (OSA) denounced the elimination of the Great Lakes Restoration Initiative, as proposed by the 2018 budget released by the Trump Administration.Ohio’s corn, soy and wheat farmers have been strong supporters of the initiative. Since 2009 it has provided approximately $300 million annually in water quality improvement efforts and generated more than $2 billion for previously unfunded restoration work over the past eight years. These investments help not only agriculture, but other stakeholders that need support to improve water quality.“The Great Lakes are the source of nourishment, fishing and recreation for millions of Americans,” said Jed Bower, OCWGA President. “If Congress enacts the administration’s budget as proposed, Western Lake Erie would be harmed by the elimination of the initiative.”The Trump Administration proposed severe cuts to Great Lakes funding for the remainder of the 2017 fiscal year budget. However, led by Sens. Portman and Brown, Congress voted to keep programs at their current funding level of $300 million.“Failing to fund the Great Lakes Restoration Initiative would come at a high cost to Ohioans,” said Todd Hesterman, OSA President. “We stand with Sens. Rob Portman and Sherrod Brown, Rep. Dave Joyce, and all members of Ohio’s congressional delegation who have led the charge to fully fund the Great Lakes Restoration Initiative.”
Also, PV systems also don’t have any moving parts to wear out or that require maintenance; freeze protection isn’t a concern; and pressure build-up from stagnation in full sun (if a pump fails or during a power outage) can’t occur. So PV systems are very attractive from a long-term durability standpoint.And if we’re generating our electricity from the sun why not use some of that electricity for water heating? That’s what we decided to do: install a PV system and heat our water with electricity. Electric water heatingSo if one goes with electric water heating, what are the options? There are three primary choices:Conventional storage-type electric water heater. This is an insulated tank that holds 30 to 80 gallons, typically, and includes either one or two electric-resistance heating elements. Better storage water heaters have more insulation, so less stand-by heat loss occurs.Tankless water heater. A tankless, sometimes called on-demand or instantaneous, water heater heats the water as it is used. This offers the advantage of eliminating the stand-by loss that occurs with storage water heaters. Whole-house tankless water heaters are most commonly gas-fired, but electric models are also available. The problem with the latter is that they require a huge amounts of electricity. An electric tankless water heater large enough to supply a shower and another use at the same time will require a 60-amp or larger circuit at 220 volts. If a lot of homeowners were to switch to whole-house electric tankless water heaters, it would put a huge burden on the utility companies that have to meet peak demand — particularly in the morning when a lot of people are showering. There are other issues with tankless water heaters that I’ve written about previously and won’t get into here.Heat-pump water heater. A heat-pump water heater extracts heat out of the air where the water heater is located (typically a basement) to heat the water. Because the electricity is used to move heat from one place to another instead of converting that electricity directly into heat (as with electric-resistance water heating), the energy yield per unit of electricity input is much greater.We measure that efficiency as the “coefficient of performance” or COP — a COP of 1.0 is, in essence, 100% efficient at converting electricity at your site into heat. Most heat-pump water heaters have COPs of 2 to 3, meaning that for every unit of energy consumed (as electricity), at least two units of energy (as heat) are generated.(Note that if we consider “primary” or “source” energy instead of site energy, energy losses during power generation reduce that effective COP considerably.) As we build more energy-efficient houses, particularly when we go to extremes with insulation and air tightness, as with Passivhaus projects, water heating becomes a larger and larger share of overall energy consumption. In fact, with some of these ultra-efficient homes, annual energy use for water heating now exceeds that for space heating — even in cold climates.So, it makes increasing sense to focus a lot of attention on water heating. What are the options, and what makes the most sense when we’re trying to create a highly energy-efficient house?

We installed a 50-gallon GE GeoSpring model and, so far, we’re very happy with it. The GeoSpring is currently available only in a 50-gallon size, though rumors suggest that a larger 80-gallon model could be introduced. Because water heaters operating in heat pump mode take a long time to heat water, larger tanks typically make sense. If our two daughters were still in the house, a larger heat-pump water heater would have been more important.One of the factors that attracted us to the GeoSpring is that it’s now being made in the U.S. GE had made its first-generation GeoSpring in Mexico, but moved that production to the U.S. two years ago.The GeoSpring doesn’t have the highest performance of any heat-pump water heater on the market; Stiebel Eltron’s 80-gallon Accelera holds that distinction, but the GeoSpring costs a third as much as the German-made Stiebel Eltron. It’s also quieter.In next week’s blog, I’ll say a little more about heat-pump water heaters, including some issues with placement and implications of the fact that heat-pump water heaters cool off the space where they are located — depending on the season, that can be an advantage or disadvantage.Understanding heat-pump water heaters is important, as they will soon become the standard at least for larger electric water heaters — based on efficiency standards that take effect in mid-April 2015. By the way, Eli Gould (the designer-builder of our home) and I will be leading a half-day workshop at the NESEA Building Energy Conference in Boston on Tuesday, March 4, 2014. In this workshop, “What Would the Founder of Environmental Building News Do? Adventures on the Cutting Edge of Green Building,” we’ll be reviewing product and technology choices, describing lessons learned, presenting data on performance, and discussing, in a highly interactive format, some outcomes from this project that can be applied much more affordably in deep-energy retrofits. This should be informative and a lot of fun. I’ll also be presenting in the main conference, March 5-6, on “Metrics of Resilience.” Registration information can be found here. Solar-electric vs. solar-thermal water heatingIf we had built our new house three or four years ago, I suspect that solar water heating would have been included — or at least very seriously considered. But as costs of solar-electric (photovoltaic or PV) systems have dropped in recent years, more and more energy experts are recommending electric water heating, rather than solar thermal, and using PV modules to generate the electricity — so it’s still solar water heating, but not as direct.That’s what we have done at our new place. We realized in our planning that we had a great location for PV modules on our barn roof, but we didn’t have a good rooftop location for solar panels on the house. PV panels can be located farther away from where the energy is being used than can solar-thermal panels, because electrons can be easily moved fairly long distances through electrical cables, while piping runs for solar-thermal systems have to be much shorter.
