first_imgA meeting will take place tomorrow (Friday) in an attempt to find a solution to the right of way access issues at Castlegoland Beach in Portnoo.An action group was established this summer after an electric fence and barrier were placed at the traditional paths to the beach which run through the Narin and Portnoo Golf Club.Locals are campaigning to restore the paths which they say had been open for at least 100 years. Knather Acquisitions, who took over the golf links last year, said that the barriers were erected on health and safety grounds.Save Our Beach At Castlegoland campaigners had scheduled another protest walk this Saturday, but this event has been postponed pending a meeting between the golf club owner and Donegal County Council this Friday.It is understood that Donegal County Council representatives and local councillors will meet with Donegal-born businessman Liam McDevitt, owner of Knather Acquisitions and the golf club, to seek a solution to the current issues.The Save Our Beach group has agreed to cancel their protest this Saturday to avoid “escalating a delicate position” as they hope for an amicable agreement to be reached.

first_img25 January 2011Creating jobs in South Africa, while at the same time striving for decent work, will be the key focus of the Labour Department’s policies in the years ahead, says Labour Minister Mildred Oliphant.“We have to ensure that our policies do not have negative consequences for employment,” Oliphant said at the annual labour policy conference in Pretoria on Monday. “Some may want to argue that our priority should be decent work. I would, however, caution against getting into an either-or debate.“What we ultimately want are jobs that are decent,” the minister said. “We know that the International Labour Organisation defines work as being productive jobs for women and men in conditions of freedom, equity, security and human dignity.”She said it was critical that the social partners at the National Economic Development and Labour Council (Nedlac) engaged seriously and vigorously with the proposed amendments to South Africa’s labour law.“I am sure we would all want the amendments to be passed into law as soon as possible so that the legal reforms can begin to change labour relations and the operation of the labour market for the better,” she said.Through the proposed changes, Oliphant said the department wanted to strengthen the powers of the country’s labour inspectorate. This would see non-compliance with the law being criminalised and penalties being increased for violation of the Basic Conditions of Employment Act and the Employment Equity Act.“The Labour Relations Act is also being amended to strengthen the enforcement of arbitration awards issued by the Commission for Conciliation Mediation and Arbitration (CCMA) as well as Bargaining and Statutory Councils.”She said it was only through co-operation, rather than competition, that South Africa’s labour market could be changed for the better.Oliphant said the strategic objectives of the department over the next five years included:Contributing to employment creation.Promoting equity in the labour market.Protecting vulnerable workers.Strengthening social protection.Promoting sound labour relations.Strengthening the capacity of labour market institutions.Strengthening the institutional capacity of the department.Source: BuaNewslast_img read more

first_imgThe upshot on range constraintsFor people to overcome range anxiety and feel comfortable buying an electric vehicle, they need to know their needs will be met on all days, including high-energy days. Predicting when this will occur — and in advance when buying a vehicle on how many days this will occur — is something that our model is well-suited for.Our model can, with limited input on travel distance, time and location, predict the probability of exceeding the car’s range, and point to days where drivers need to turn to other, longer-range cars, for example, within households, or even within communities and through commercial car-sharing programs. The results also shed light on the quantity of long-range cars that would be needed at the population level, a gap to be filled by private sector innovation as well as national and local policy.Reasonable financing to help distribute the upfront costs over the car’s lifetime and increasing the opportunities for charging, even if only once daily, would also encourage EV adoption.In all, our analysis shows that current electric vehicles can meet most daily driving needs in the U.S. Improved access to shared, long-range transport, alongside further-advanced batteries and cars and decarbonized electricity, provides a pathway to reaching a largely decarbonized personal vehicle fleet.

Trancik is an associate professor in energy studies at the Massachusetts Institute of Technology. This column was originally published at The Conversation. To realize this potential, however, the needs of prospective electric vehicle drivers have to be met on all days, even high-energy ones, such as days that require long-distance travel.Two key innovations can enable this. The first is to predict the days on which drivers are likely to exceed the car’s range, which our model is designed to do. And the second is institutional or business-model innovation to provide alternative long-range vehicles on those high-energy days. For example, conventional cars, and eventually low-carbon, long-range alternatives, might show up at a user’s door at the click of a button. This need may last for some time even as battery technology improves and charging infrastructure expands. Vehicle range is not a single numberAn electric vehicle’s range is typically thought of in terms of a fixed number, but the number of miles covered on a single charge changes with factors including driving speed, driving style, and outdoor temperature. To understand the range of a car, we need to look beyond the car itself to how people are behaving.Over the last four years in my research group, we’ve built a model (called “TripEnergy”) of the second-by-second driving behavior of people across the United States, how they are likely to use heating and cooling systems in their cars, and how various electric and conventional vehicles would consume energy if driven in this way.This approach gives us a probabilistic view of electric vehicle range. For example, for the Nissan Leaf, we find that 74 miles is the median range — based on driving patterns, half of the cars on the road in the U.S. would be able to travel this far, and half would not. (A Ford Focus electric performs similarly.) There is a distribution in this range, which demonstrates how widely actual performance can vary. We estimate, for instance, that 5% of 58-mile trips could not be covered on one charge, and 5% of 90-mile trips could. RELATED ARTICLES By JESSIKA TRANCIKElectrifying transportation is one of the most promising ways to significantly cut greenhouse gas emissions from vehicles, but so-called range anxiety — concern about being stranded with an uncharged car battery — remains a barrier to electric vehicle adoption. Is range anxiety justified given current cars and charging infrastructure?It’s a question my research group and I addressed in a paper published in Nature Energy, by taking a close look at this problem with a new model.Specifically, we asked: When looking down on the geographic area of the U.S. from a bird’s-eye view, how many personal vehicles on the road daily could be replaced with a low-cost battery electric vehicle (EV), even if daytime charging isn’t available? Our analysis is, to our knowledge, the most expansive yet detailed study to date of how current and future-improved electric vehicle technology measures up to people’s energy-consuming behavior.We found nearly 90% of vehicles on the road could be replaced by a low-cost electric vehicle available on the market today. What’s more, this number is remarkably similar across very different cities, from New York to Houston to Los Angeles. That is, there is a high potential for electrification of cars in both dense and more sprawling cities in the United States. Returns on technology improvementWhat if batteries improve, and allow for longer driving range for the same cost as current-generation lithium ion batteries?The 2015 Chevrolet Bolt EV concept vehicle, which is expected to sell for about $30,000 when it goes into production later this year. (Photo: General Motors)The federal research agency ARPA-E has set a target for batteries to store roughly two times more energy by weight than today’s batteries in electric vehicles. If that technical target is reached, we estimate that the 87% daily adoption potential estimate would rise to 98%, and the gasoline substitution potential would rise from 61% to 88%. The 2017 Chevy Bolt and 2018 Tesla Model 3 are expected to achieve roughly similar increases in potentials at an increased cost compared to today’s Nissan Leaf, though these costs are still close to the average cost of new cars. The Tesla Model S travels even further but costs significantly more.Even with substantial battery improvements, however, other types of powertrain technologies will be needed to cover those days with the highest energy consumption. This need may persist for some time, even with expanded charging infrastructure, due to a small number of very high-energy days. Evaluating electric vehicle technology against driving behaviorWith the TripEnergy model in hand, we asked how many cars on the road could be replaced with a low-cost electric vehicle available today. We considered a case where drivers can charge only once daily: for example, at home overnight. This allowed us to study a situation where only limited changes are needed to existing public charging infrastructure and cars can use power plants that would otherwise sit idle overnight.We found that, given how people are driving across the U.S., 87% of cars on an average day could be replaced with a current-generation, low-cost electric vehicle, with only once-daily charging. This is based on the driving behavior of millions of people across the U.S. across diverse cities and socioeconomic classes.Switching from conventional to electric vehicles for those cars would cut emissions by an estimated 30%, even with today’s fossil fuel-based supply mix. In total, the trips taken by those cars represent roughly 60% of gasoline consumption in the U.S.This large daily adoption potential is remarkably similar across both dense and more sprawling U.S. cities, ranging from 84% to 93%.While it’s true that people behave differently across cities — in how they use public transport, whether they own a car, and how often they drive the cars they own — when they do drive, we found that a similar number of cars in different cities fall within the range provided by a low-cost electric vehicle.last_img read more

first_img LongVersion_Electric_Auditing_Handout_2018edits.pdf Are batteries really necessary?One issue with a PV system is whether the electricity it generates can be used during a grid outage without the addition of a battery.Brian P writes that Pika Energy offers an inverter that appears able to work in a grid-tied system as well as an independent “island” when the grid is disabled. But Pika tells Sheehy that its system doesn’t allow PV electricity to be used when the grid is down except through a battery, which to Holladay means it can effectively function as an off-grid system.Thomas Stone points to two companies that make grid-tied inverters that will operate when the grid is down (and assuming there is sunlight). One is made by SMA, and another is called the Solar Edge.Kevin Spellman has another suggestion: a system from Schneider Electric, which includes an inverter, a generator and lithium-ion batteries.“So,” he says, “it can be done.”But prices are high. The 19.5 kWh battery that Spellman references costs $14,900, which by Holladay’s calculations stores the same amount of electricity you can buy from the grid for between $2 and $4.“Batteries are expensive,” he says. “Grid electricity is cheap.” Writing from central Kentucky, Clay Whitenack poses this question: in an all-electric house, what’s the best way of providing power when the grid is down?Whitenack and his family live in a new house, a house that does not have a fireplace or a wood stove. “This leaves us vulnerable in the event of a power outage during a bad winter,” he writes in a post at the Q&A forum. “We live in central Kentucky, so the winters here are usually not too bad, but we do have times when the temps get below freezing for extended periods of time.”The house is well-insulated and heated with ductless minisplits; domestic hot water is produced by a heat-pump water heater. Whitenack’s first thought about emergency backup power is a solar array.“I would like to start researching a small solar array that would allow me to keep the essentials going,” he says. “Things like heat, hot water, the fridge, stove, and maybe a few outlets around the house for a few lights, charging mobile devices, etc.” He wonders how to calculate the amount of electricity he’d need in a pinch, and what the capacity of a photovoltaic system might be. At least that’s where this Q&A Spotlight begins. Battery technologies are differentBoth the Tesla and LG batteries are lithium-ion, while Holladay’s system uses older generation lead-acid batteries, which can be charged with a generator.“Using a generator to charge a battery bank is fairly simple,” he says. “Most off-grid inverters include a battery charger. Off-grid homeowners start up the generator when it’s been cloudy for a few days. When necessary, I plug my house into my generator. When the inverter senses the generator power, it automatically charges the battery at a rate of about 90 amps (tapering down to 40 or 50 amps when the batteries are close to full). While the generator is running, there is also plenty of extra power to run the washing machine or other appliances.”Although it’s not immediately obvious to Holladay why a generator can’t be used to recharge a lithium-ion battery — after all, the internal combustion engine in a Prius is capable of charging the car’s lithium-ion battery — a little internet sleuthing suggests it’s not as simple as it may seem. He finds that lithium-ion batteries may need an automotive alternator rather than a generator for charging, “or a set of old-fashioned lead-acid batteries as a buffer for the generator.”The reason for that is complicated, but Holladay refers Whitenack to an article with a longer explanation.Calum Wilde disagrees. “If the [Powerwall] is being charged by mains power it shouldn’t matter if that 240 volt AC is coming from the grid or your generator,” Wilde writes “The only way it could matter is if the hookup method purposefully prevents it. But the battery charger/inverter shouldn’t care. If I were you, I’d ask about that setup on Reddit. They’re generally a great bunch of professionals with collectively an immense amount of knowledge.” Adding batteries to the mixIf Whitenack follows the more expensive solar route, Dorsett suggests looking into a “battery-ready” inverter, which would allow the addition of a battery in the future — when demand charges are introduced for residential electricity customers, for example.“The cost of lithium-ion batteries is still in free-fall on a double-digit learning curve,” Dorsett writes. “At some point in the next decade it will be worth it, even if the primary use is as backup rather than demand-charge mitigation.” He points to a Bloomberg report that says the price of lithium-ion batteries in 2016 was $273 per kilowatt hour, a decline of 73% since 2010.But the addition of storage batteries also raises other questions while making the system more complex and more expensive.Sheehy says his research for backup power included two quotes for a battery. A Tesla Powerwall would have cost almost $14,000, while a competing battery from LG would have been almost $12,000. Those options would have provided between 12 and 14 kWh of energy storage, and he would still have needed a gas-powered generator.“Both systems quoted to me could not be charged by the generator,” Sheehy adds. “That meant that in an outage I’d need to go back and forth between battery and generator.” Our expert’s opinionPeter Yost, GBA’s technical director, added these thoughts:It’s difficult to add much to the practical information and insights already offered by Martin Holladay and others. But I wanted to share some information I have gathered from two conference presentations. One was the 2013 Better Buildings Better Business conference in The Dells, Wisconsin, where my friend and colleague Dan Cautley of Seventhwave spoke. The other was just last week when Marc Rosenbaum presented at the Better Buildings by Design conference in Burlington Vermont. Both were outstanding events.Dan’s presentation “Electrical Energy Auditing: Typical Use by Appliance,” is a great way to estimate electrical loads when trying to design a back-up system. I pulled these out of his work because Clay Whitenack listed them:Heat-pump water heater: Typical annual use 800 kWh.Refrigerator: Draws 725 watts; typical annual consumption 1000 kWh.Stove/range: Draws 1,500 watts; typical annual consumption 300 kWh.Lighting (50 lamps): Draws 2,364 watts; typical annual consumption 1560 kWh.Phone and camera chargers: Draw 2 watts; typical annual consumption 11 kWh.For those trying to figure out just what essentials can be covered, Dan’s work is pretty helpful, even if it is a bit dated.I can report on Marc’s presentation only indirectly. I’m sorry to say I didn’t get to that session because it competed with another talk I wanted to hear, But friends and colleagues Eli Gould and Jim Duran of PreCraft had these takeaways:Even a thrifty family in a small house would need “huge” storage capacity to cover the starting and sustained power draws from essential appliances and lighting.Reducing the heat load helps a lot, so a wood stove looks mighty attractive for covering power outages.It’s really hard to eliminate the need for even a small generator to offset the four-day, cloudy winter scenario.Marc’s calculations on generator emissions show that even the most efficient generators are way worse than the grid.Considering the current limitations in batteries, and the diminishing returns of increasing total battery capacity, you just can’t store enough energy to last through a long outage without the help of the generator.NOTE: Efficiency Vermont has posted the presentations from this year’s Better Buildings By Design conference. Marc Rosenbaum’s presentation was called “PVs and Battery Storage.” RELATED ARTICLES A PV system isn’t cheapGBA editor Martin Holladay, who has lived off the grid for many years, points out that installing a PV system is expensive. Solar panels, batteries, a charge controller, and an inverter, sized for backup at a house that uses fossil fuels for space heating and domestic hot water could cost between $10,000 and $20,000, Holladay says. “If the house uses electricity to provide space heating and hot water,” he writes, “it would be hard to even imagine the size of a battery big enough to get the house through a few cloudy days. Such a system would cost a fortune and would be a maintenance headache. It’s far cheaper to spend $1,200 to $2,000 on a gasoline-powered generator.”His own generator is a Honda that can crank out 5,000 watts. It cost a little more than $2,000, and it can produce both 120-volt and 240-volt electricity.Whitenack admits he hadn’t considered buying a generator. While that option does look cheaper and easier to install than a solar array, the long-term financial picture isn’t as attractive.“What about the long-term returns of a solar system vs. a generator, though?” he asks. “I plan on living at this location for another 40-50 years, God willing. A PV system would allow me to offset my energy bills, which a generator would not.”And generators can easily top the $2,000 that Holladay mentions.Stephen Sheehy, for example, writes that after looking into possible backup power sources for his Maine home, he settled on a 7,000-watt Honda. After hiring an electrician to install an exterior receptacle that could handle the generator’s 30-amp output, he ended up spending a total of $6,000.“I tried to shop around but most dealers didn’t have any Hondas available,” Sheehy said. “It’s a nice, quiet machine with inverter technology that lets me run my minisplits.” How long is an outage really going to last?A well-insulated house in Kentucky isn’t likely to have plumbing freeze-ups even in very cold weather, says Dana Dorsett, so a small woodstove might be enough to keep everyone comfortable during a power outage, and it would not require “punching huge holes in your efficient building envelope.”More to the point, Kentucky has a reliable electric grid and power outages that extend beyond a day or two are “extremely rare,” Dorsett says, adding, “The capital budget for equipment to cover trailing-edge 0.001% risks should be sized accordingly.”But Whitenack isn’t as concerned with a brief outage as he is with an extended grid failure, something caused by a natural disaster that disables the local power plant and leads to a blackout measured in weeks.“It’s not a huge fear of mine,” he says. “I’m not obsessed with zombie-apocalypse scenarios, but I have a young family and this is the first house I’ve lived in that hasn’t had some option for backup heat.”Still, that shouldn’t be an issue in Kentucky, Dorsett tells him. In the central part of the state, there’s plenty of redundancy built into the grid.“Grid planners in Kentucky are also further along than most states with smart-grid planning and development, making the grid more reliable in general, but also ‘self healing’ for re-routing power when major links go down,” Dorsett says “It’s definitely a first-world power grid environment, nowhere near as vulnerable as New Jersey and New York were during Superstorm Sandy.” Batteries for Off-Grid HomesHow to Design an Off-Grid HouseAn Introduction to Photovoltaic SystemsGreen Basics: Photovoltaic (Solar Electric) SystemsVermont Utility Is the First to Offer Tesla BatteryTesla Will Sell Home BatteriesBackup Electrical Power for a Passivhaus Project Do Grid-Tied Photovoltaic Systems Really Have an Advantage?How to Live Comfortably Off the Gridlast_img read more
