Understanding Light Bulbs - CFLs vs LEDs
LEDs do not “burn out” like traditional bulbs and can reduce cooling costs since they emit very little heat, and heat is what wastes energy when you’re talking about lighting. This style of bulb is very durable, as it does not have a fragile shell or filament that may shatter, as happened frequently with conventional incandescent bulbs.
CFL BULBS
CFLs, or compact fluorescent light bulbs, are the tubular- and helical-shaped bulbs that use about 75 percent less energy than a traditional incandescent bulb. They are relatively inexpensive, though not as efficient in comparison to LEDs. Their lifespan is about nine years with normal usage and they can save you up to 75 percent on energy bills.
CFLs do contain a very tiny amount of mercury, about 4 milligrams per bulb, which is never released while the bulb is in use or intact. Your local waste collection agency can advise you on proper recycling of these bulbs.
HALOGEN BULBS
Halogen bulbs are another option to consider. They look and perform much like the conventional incandescent bulbs that are being phased out. Their energy savings and longevity does not compare to CFLs or LEDs, though they are still more efficient than the traditional option."

Is LED The Most Efficient Lighting Technology?
However, since LEDs come up to full brightness instantly in sub-zero temperatures, they can be fitted with occupancy sensors that only turn the light on when people are in the room. They can therefore cut their energy consumption significantly by automatically turning off when no one's around.
But of course, these are just a couple examples of factors that can affect the efficiency of any given lighting technology. The truth is, there are a whole host of other factors that could tip the scales in favor of one technology or another.
In some situations, the features of the LED-based fixtures might add enough efficiency to a system to overcome the disadvantage created by their initial cost. In other situations, fluorescent fixtures will still be the more affordable, more efficient choice.
Which brings us to our rather unsatisfying conclusion:
Efficiency Winner: It Depends
Price Winner: It Depends
ROI Winner: It Depends"

LED vs CFL -- Which Light Bulb is More Efficient? | CleanTechnica
One factor is cost. If your primary concern is price, the CFL would be a better choice. Although the CFL has a shorter lifespan, even if you replaced the CFL three times to achieve an equivalent lifespan to the LED, you’d still have only spent $2.58 in comparison to the LED’s $45 initial purchase price.
Another factor is location. If the fixture you’re mounting the bulb in is in a place where it’s a hassle to change, that $40 difference might be worth not having to deal with it for the expected 20+ years of normal usage you’ll get out of the single LED.
The bottom line is that in a household setting, where optimal components and ideal conditions cannot be controlled, the LED and CFL light bulb are very close competitors. The decision for one over the other should be made based on the goals of the project and you may even require a mix of technologies to meet those goals."

Mish's Global Economic Trend Analysis: Meet "McCashier" Your $15.00 Per Hour McDonald's Worker Replacement
Math, Not Counting Benefits
For a location open 24 hours: The cost of human cashiers, not counting benefits, $15/hour * 24 hours * 365 days/year = $131,400
For a location open 6AM to Midnight: $15/hour * 18 hours * 365 = $98,550.
For the machine to be cost effective, all it needs to do is cost less than $100,000 a year to buy and maintain.
By the way, it won't just be McDonald's that eliminates cashiers. Expect to see machines like that everywhere. Basic cost-accounting math demands that outcome.

In L.A., getting paid to go green - Los Angeles Times Sunstarter
"What the LADWP did right is to see this as a way to get solar throughout a lot of different places in the city. It demystifies the whole concept," Jenal said. "From the stated goal, there is no place better than nonprofits -- places where people come to congregate, come to learn -- for them to learn about the value of sustainable energy."
Leslie of the LABC said residents and smaller organizations that can't shoulder the cost of a full solar installation can still invest as shareholders in nearby projects, and would see a return once these projects become profitable.
"We didn't want a program that would only be for a select part of the city," Leslie said. "We want to make sure that solar is diverse."
"We have sunshine over 300 days a year. The sun's free," she said, "so the better we get at harnessing it, the better off we're going to be.""

Lyft, Uber Edge Closer to True Ridesharing
Another upshot to the carpooling service is that it could service people who don’t live near existing public transportation lines. In fact, Lyft says its carpooling function is creating a new category of transportation — personal transit. The company said in a blog post:
“Personal transit is about access for everyone. We believe that modern cities should offer reliable, affordable transportation wherever you live. We want to bring the best parts of Lyft — on-demand service, door-to-door trips, and community — to daily travel.”
Lyft and Uber have been locked in an epic battle for ridesharing … or should I say, TNC … supremacy. Lyft’s closing of a $250 million Series D round in April finally leveled the playing field against Uber’s Google-backed endowment. For now, the incessant competition seems to be benefiting consumers with ever-more exciting innovations. Stay tuned for what else awaits further down the road."

Blowback! U.S. trained Islamists who joined ISIS (jIST LIKE BEFORE)
WND further reported that, according to a Shiite source in contact with a high official in the government of Iraqi Prime Minister Nouri al-Maliki, the Obama administration has been aware for two months that the al-Qaida-inspired group that has taken over two Iraqi cities and now is threatening Baghdad also was training fighters in Turkey.
The source told WND that at least one of the training camps of the group Iraq of the Islamic State of Iraq and the Syria, the ISIS, is in the vicinity of Incirlik Air Base near Adana, Turkey, where American personnel and equipment are located.
He called Obama “an accomplice” in the attacks that are threatening the Maliki government the U.S. helped establish through the Iraq war.
The source said that after training in Turkey, thousands of ISIS fighters went to Iraq by way of Syria to join the effort to establish an Islamic caliphate subject to strict Islamic law, or Shariah."

Working under fire at Gaza’s only commercial transit point | JPost | Israel News
Kerem Shalom was initially designed as a secondary transit point for goods that could augment or be used instead of the larger Karni crossing at the northern edge of the strip. But after Hamas took over the territory in a bloody 2007 coup, Karni was closed for security reasons, as were a number of smaller crossings, such as Sufa and Nahal Oz. All were replaced by Kerem Shalom, which in spite of the danger of mortar and rocket fire has been deemed the safest passage point because it is far away from populated areas."

LED Light Bulb Prices Hit New Lows as More Energy-Efficient Models Arrive
LED Light Bulb Prices Hit New Lows as More Energy-Efficient Models Arrive
*Last Modified: June 6th, 2014Shopping at Home Depot this week, I was pleased to discover on Aisle 36 that both Philips and Creejust slashed several LED light bulb prices by more than 20 percent, with competing 60-watt indoor replacement bulbs — consuming only about 10 watts each — now going for under $10.
It's about time these top-rated suppliers began offering their more durable, more efficient and longer-lasting household light sources at more affordable prices. Until now, only lower watt-equivalent indoor options were available in the single digits — and these are generally lower-rated products with inferior light quality and questionable lifetime claims that my wife simply cannot tolerate.
She also doesn't like to spend more than $10 on a single soft-white light bulb either, even if it is going to last potentially decades longer than traditional bulbs and save a couple hundred dollars on energy costs over the years.
Neither, frankly, do I.
But $9.97 for the Cree 60-watt equivalent dimmable LED light bulb — my personal favorite in this class because of its light quality and similar appearance to a traditional bulb — or the uniquely shaped Philips SlimStyle 60 watt equivalent can still be a tough sell based strictly on sticker shock.
Brighter LED bulbs can cost double or triple these 60 W replacements. Cree's new 100-watt equivalent bulb — announced this week — retails at a "breakthrough price of just $19.97," according to the North Carolina-based manufacturer, which claims it is the "lowest-priced 100-watt LED replacement bulb."
My local Home Depot didn't yet have this new product in stock, which uses just 18 watts to produce a brightness of 1,600 lumens. The most comparable bulb is the Philips 100-watt equivalent, which is one of the most aesthetically pleasing LED household bulbs on the market and gives off a nice, warm light. The retail price recently was cut by $8 to $24.97. Important to note, however, is that Philips has the Energy Star rating that qualifies for rebates, while Cree does not yet have the rating.
But there is other competition on Aisle 36: Compact fluorescent light bulbs (CFLs). These cost less and save money at a faster rate than LEDs.
According to Consumer Reports, CFLs also use about 75 percent less energy than incandescent bulbs, only slightly less than LEDs. CFL's also disperse light in all directions, which LEDs are not very good at. LEDs, on the other hand, are mostly dimmable, while CFLs mostly are not dimmable — which is a big factor in my household.
Other points in LEDs' favor is the fact that CFLs contain small amounts of mercury and have a much shorter lifespan, at least theoretically, than LEDs.
Lower prices for LED light bulbs would make the decision a lot easier.
But a lot of progress is being made, with prices continuing to fall steadily over the past year. According to market researchers at IHS Inc., average global LED light bulb retail pricesdropped by almost 12 percent between February 2013 and February 2014 to $23.80. That's still not cheap.
The reduced prices for 60-watt equivalent Philips and Cree LED bulbs this week to under $10 come at a good time — just a few months after the United States banned those inefficient old 40 and 60 watt incandescent light bulbs, as mandated by the Energy Independence and Security Act of 2007, which already phased out 100-watt incandescent bulbs in 2012.
Lower prices, more choices and better products are expected to help LED's gain further market traction in coming years. IHS forecasts the global market for general lighting LEDs to grow to 3.6 billion units shipped in 2020 from 495 million units in 2013, with penetration rising from just 3 percent of all light bulbs to more than 30 percent.
Better make room on Aisle 36.

Qatari emir in Jeddah for talks with Saudi king - Al Arabiya News
Under his rule, Egypt has tightened its hold on the southern end of the Gaza Strip, closing tunnels to try to block supplies of weapons and prevent militants crossing.
Egyptian officials suspect Qatar encouraged Hamas to reject the ceasefire plan Cairo put forward last week. Hamas sources in Doha, however, say Qatar did not influence their decisions.
"Qatar is helping us in communicating our message, that's all it is," said a Doha-based Hamas source. He added that the group was never approached by the Egyptian authorities, and it could not agree to a deal it had never been part of."
