An Energy Efficiency Showcase was held at Friends Meeting House in Derby, UK with displays and example systems showing PV panels, solar water heating, insulation, air and ground source heat pumps. A range of books were available to borrow together with smart meters and smart plugs to turn off appliances when not in use. The Meeting House solar
panels and controls were on display together with explanations of the zoned heating and lighting - which have helped the Meeting House meet
their 10:10 commitment.
On May 5, 2010, Efficiency Maine presented the Lewiston School Department with recognition awards for their dedication and implementation of energy saving efficiency measures in their schools.

Im a pretty unconventional student. Most people prefer a quiet library as a place to efficiently study by dentying themselves the glory of the outside world. Efficiency though misery, lets say.
I long ago realized that if you like what youre studying, its works better in a place that you enjoy. Which, in college, led to the majority of my education taking place at two places. Firstly Phish show parking lots, and secondly Lincoln Woods, in RI. So instead of the library, my idealized image of myself as a studious university student was me in the woods with a hooded sweatshirt, blanket, music, and occaisional dip ion the lake as a study break.

Bad Example of outdoor lighting. Can you see anyone behind the light? This is pretty much as it looked to the eye. You can't really see anything underneath the light against that glare.

Alabama Gov. Robert Bentley details a plan to increase efficiency among state-level law enforcement agencies, Tuesday, Jan. 22, 2013, at the state Capitol. Bentley said he will name Spencer Collier, right, as the state's Senior Law Enforcement Advisor. Collier will continue to serve in his role as Director of the Alabama Department of Homeland Security and will coordinate with individual agencies in efforts to streamline state-level law enforcement functions. With Bentley and Collier, from left, are: Col. Hugh McCall, Department of Public Safety; Mac Gibson, Director of the Alabama Department of Beverage Control; Jim Riddling, Commissioner of the Alabama Department of Insurance; Gunter Guy, Director of the Department of Conservation and Natural Resources; and Julie Magee, Director of the Department of Finance.

The Army has saved millions of dollars through a variety of efficiencies in purchasing ammunition, including reducing the procurement of Excalibur projectiles, which saved nearly $400 million. The M777A2 Howitzer is another program in which the Army has executed BBP initiatives. Here, a U.S. gun crew fires illumination rounds Jan. 4 at Forward Operating Base Hadrian in Uruzgan province, Afghanistan. The gunners are tasked with providing offensive support to Combined Team Uruzgan missions using the M777A2, a towed 155 mm artillery piece that fires high-explosive, illumination and GPS-guided Excalibur rounds.

Interesting graph provided by Shimano regarding the mechanical efficiencies of two of their 8-speed IGHs. This may explain why in some speeds, the hub feels "sluggish" or harder to pedal than in another gear. Note the huge increase in efficiency when switching from 4th to 5th. This is much more pronounced in their lower end hub than in their higher end model.
However, from the perspective of a scientist who generates and scrutinizes such graphs daily, this graph, while interesting, is largely meaningless due to the unit-less y-axis. Are we supposed to be looking at percent efficiency? What is the axis range? If the y-axis in fact represents percent efficiency and the axis range spans 0-100% (for example), then the graph indicates a very pronounced effect from a practical standpoint (i.e., ~35% efficiency in 4th gear, and ~95% efficiency in 5th gear). But if, hypothetically, the axis range represents a narrow efficiency range--say 40-50%--then the peaks and valleys are largely insignificant in the real world (representing about 43% efficiency in 4th compared with 49% efficiency in 5th). Take-home message: be careful how you interpret this data!
Under BBP, commands assess their mission requirements and then determine where they can achieve efficiencies without degrading capabilities. Here, a route clearance patrol of Joint Task Force (JTF) Empire conducts operations in southern Afghanistan. During Operation Shrimp Net in July 2012, JTF Empire staff identified the need to move route clearance patrols from one area of operation to another, thus allowing for better assessment and allocation of engineer resources throughout Afghanistan.

차세대 STAFOR 이온 보일러가 여러분의 난방비용을 줄여줍니다.
에너지 가격변화와 새로운 난방기술의 출현, 환경 주택에 대한 관심의 증가로 인하여 사람들로 하여금 난방에 대한 다른 보완적 대안을 찾도록 강요하고 있습니다.
전기 에너지를 활용한 난방은 “비용이 너무 많이 든다.”는 고정관념이 있습니다. 어느 정도 맞는 이야기이긴 하지만, 반드시 짚고 넘어가야 할 사항이 있습니다. 이런 생각은 일반적인 물을 채운 시스템에서 사용되었던 TEN 보일러에 들어맞는 이야기입니다. 관형 발열체(TEN)의 표면은 매우 빠르게 소금의 단열 층을 흡수하고 보일러의 효율은 70% 이하로 떨어집니다. 결국, 에너지 효율이 낮다는 것입니다. 시간이 흐르면 관형 발열체는 과열되어 쉽사리 고장이 나게 됩니다.
이온(전극) 보일러가 갖춰진 난방 장치에서는 이와 같은 결점을 찾아볼 수가 없습니다. 관형발열체에는 전달 링크가 없어서, 시스템 난방이 직접 특수 히트 캐리어의 전기적 특성으로부터 난방 시스템으로 채워집니다. 이 히트 캐리어는 소금 속으로 침투하지 않고, 열 전달 표면이 깨끗하며 전체적인 난방 시스템의 작동은 양호하며 또한 경제적입니다.
라트비아에서 6년간 STAFOR 이온 보일러가 장착된 난방시스템을 가동해본 결과, 석유연소 방식이나 액화가스 방식보다 저렴하다는 것을 알 수 있었습니다. 보다 저렴한 천연가스는 “파이프”나 장작, 목탄 등과 같은 고체연료에서 구할 수 있습니다.
일반 단열재로 둘러싸인 62.5㎡의 가정용 방을 가열할 수 있는 225,000원의 보일러와 비교하여, STAFOR 이온 보일러가 장착된 시스템의 낮은 원가를 고려할 때, 이 보일러가 장착된 난방장치는 비용이 저렴하며 타당한 대안입니다.
이온 난방 보일러의 장점은 다음과 같습니다.
● 어떠한 방에서든 1㎡의 벽 공간에 설치할 수 있는 작은 크기,
● 조용한 운영,
● 난방비 절감을 위하여 시간대 별로 가동모드를 설정할 수 있습니다.
● STAFOR 이온 보일러는 설치가 쉽고 신속합니다.
● 연소기능이 없어 화재나 폭발에도 안전합니다.
● 작은 연료요구량
● 기존 시스템에 새로운 난방 시스템을 설치할 수 있습니다.
● 다른 난방 보일러와 병렬 구성이 가능합니다.
● 시스템 결빙 방지(히트 캐리어는 -40°C까지 얼지 않습니다.)
● 친환경적인 장점
● 차세대 에너지 절감 자동화
● EU표준에 따른 1등급 전기안전 준수(인증서 번호: T25D07, T37D08)
● STAFOR 이온 보일러에 대한 COP 157% 기록
The Wirecom building, outside Orléans in France, reaches very high energy efficiency thanks to its design. Two regular buildings, with outside insulation and wood cladding, are sheltered under a glass-house bearing photovoltaïc panels on top. The glass-house provides a microclimate in winter, sharply reducing heating requirements. Automated openings along both sides and massive underground ventilation pipes take care of cooling in summer.
Yearly energy consumption < 50 kWh/m² for heating, cooling, ventilation and hot-water production.
No advanced material was used whatsoever. Design is all it took to achieve this rather high energy efficiency. Except for lighting : only LEDs are used, which makes for a ridiculously small total power requirement of 786 Watts. These are Watts, not kW, and 786 W is all the electrical power required to properly light up an 1511 m² office building with LEDs.
1511 m², total construction cost € 2,1 Million, which translates into € 1390 /m².

Wirecom is a French building-controls company and commissioned this building for its headquarters.
