The United States Department of Defense’s (DOD) interest in improving energy security through microgrid technology stems from its heavy reliance upon all forms of fossil fuels, often imported from regions of the world hostile to U.S. interests.

Duane Tildens insight:

"Microgrids can shrink the amount of fossil fuels consumed to create electricity by networking generators as a system to maximize efficiency. They can also be used to help integrate renewable energy resources (such as wind and solar) at the local distribution grid level."

Frustrated Installers Say Permitting Holds Back The U.S. Solar Market

"More than one-third of U.S. solar installers believe that permitting requirements are limiting market growth, according to a new nationwide study conducted by Clean Power Finance."


Duane Tildens insight:

"AHJs report that installer errors and incomplete or inconsistent paperwork create extra work and delays for their staff. AHJs often operate in sub-optimal conditions that include strained budgets, lack of resources and high staff turnover; furthermore, in some areas where solar installations are less common, AHJ staff is simply unaware of existing practices or that problems even exist for installers.

Even if AHJs understand solar and want to work with installers, there is currently no channel by which they can communicate to installers about updates or process improvements, the company adds."

The Business of Energy Management

When we look back on 2012, most of us will likely remember it as a year of extreme weather. In the summer particularly, record heat and drought coupled with a struggling economy had consumers doing all they could to find ways to save on energy.

Duane Tildens insight:
# One of the most powerful tools does not have to be a piece of technology, but a strong management system. Companies should consider centralizing their data and creating incentives. |

# Alternative energy can also help in managing unpredictable energy prices. In the cost-conscious world of business, making these investments can be challenging in the face of the competitive business case process.  We have found success in these deals by combining financial variables – areas with high electricity rates and available financial incentives – with funding mechanisms like a Power Purchase Agreement (PPA) – to create steady electricity cost models that are competitive with current rate structures. |

Berkeley Labs Advances Open ADR

Berkeley Labs Advances Open ADR | Green Energy Technologies & Development | Scoop.it

In 2002, Lawrence Berkeley National Laboratory introduced its non-proprietary Open Automated Demand Response (OpenADR) -the standard for open automation of building electricity demand response and price communications.


"According to Berkeley Lab, although OpenADR 1.0 was developed for US markets, it is now becoming an integral component of the international Smart Grid, as well.

 

The demand response (DR) interface facilitates open, standardized communication that enables power providers and managers to securely communicate wholesale and retail price and reliability as well as DR program information with customers using existing electronic communications."

 

...

"OpenADR 2.0a was released in August 2012, and 2.0b is currently in development. The OpenADR 2.0a profile specification addresses cyber-security requirements and facilitates global interoperability standards. It enables commercial, industrial, and residential customers to automate their response to high energy prices and grid instability through demand response; helping them better manage their energy costs during peak demand periods, while helping utilities maintain grid reliability during those high points of electricity demand."

The Negawatt Revolution -- Solving the CO-2 [& Energy] Problem --

Introduction

"My 1976 article entitled "Energy Strategy: The Road Not Taken?" which appeared in Foreign Affairs, suggested two ways in which the energy system could probably evolve over the next fifty years or so, using the United States as an example. If you divided by something like a factor of nine or ten, you would get Canada."

 

...

 

"If the U.S. spent only enough on efficiency to keep up with growth and demand for electric services, plus the net retirement of generating capacity, we would have almost enough capital left in surplus to double our rate of investment in durable manufacturing industries."

 

The Importance of Electrical Efficiency

 

"Why do I concentrate on electricity? First, because it is by far the costliest form of energy. Each cent per kilowatt-hour is equivalent in heat content to oil at $17 dollars a barrel, roughly the world oil price. So the electricity we buy, even in Canada where it is quite cheap, is equivalent to heat at many times the world oil price. Therefore saving electricity is more financially rewarding than saving direct fuels. In addition, electricity has enormous capital leverage because central electric systems -- the whole systems -- are about 100 times as capital intensive as the traditional direct fuel systems (you know, Texas and Louisiana and Alberta oil and gas -- the sorts of things on which our economies were built). In fact a quarter of all the development capital in the world goes to electrification.

 

 

"Also electricity has huge environmental leverage. Power plants burn a third of the fuel in the world. They account for a third of the CO2, therefore, released from the burning of fossil fuel. In my own country they release two thirds of the sulphur oxides and a third of the nitrogen oxides. What's more, every unit of electricity you save at the point of use saves typically three or four units of fuel, namely coal at the power plant. And in socialist or developing countries that ratio is more like five or six to one.

So you get the most environmental benefit from saving electricity, as well as the most financial benefit."

Get a fast payback with synchronous motors - Energy Management

Get a fast payback with synchronous motors - Energy Management | Green Energy Technologies & Development | Scoop.it

DC motor replacement  - synchronous motors are increasingly the motor of choice in high power, heavy load applications.



"Synchronous motors provide high efficiency in applications ... resulting in low operating and maintenance costs. ... include crushers, mills and conveyor belts in mining and quarry operations; fans, pumps and compressors in steel plants; pulp and paper extruders; chippers and de-barkers in wood processing; sewage system pumps; large compressors and fans in chemical and petrochemical applications; mills and crushers in cement works; and water injection pumps on floating oil platforms."

 

DC motor replacement

As they have a higher efficiency level, reduced size and higher output rating capacity, synchronous motors can replace DC motors in high performance applications.

 

Synchronous motors have better efficiency and speed accuracy than induction motors. However, when comparing the two, the design of synchronous motors is more complex. As a result, induction motors are less expensive for a given power level, at power outputs up to 10kW. However, above this figure the higher efficiency of synchronous motors delivers lower operating costs.

IBM deploys its Tririga building sustainability suite for the U.K. Ministry of Defense.

 

"IBM bought Tririga in 2011, and has since built on the San Francisco-based startup’s core real estate portfolio management capabilities. For example, IBM has used its in-house sensor and interval meter data sampling and monitoring technology to create a new application, called Tririga Energy Optimization, that uses data analysis to seek out previously unknown opportunities for efficiency, as well as ranking them against one another in terms of ROI, Bartlett said."

 

"...This year it landed a contract with the U.S. Air Force to apply the Tririga platform to its 626 million square feet of real estate across 170 sites around the world, and it is also leading a consortium involved in a 50-building energy efficiency project with the U.S. General Services Administration, the federal government’s landlord."

 

"...The Pew Charitable Trusts has projected that U.S. military green spending could reach $10 billion by 2030, including biofuels, batteries, renewable energy and other technologies."

Group: Energy-efficiency incentives can save billions for Arizona | Arizona Capitol Times

Arizona households and businesses can cut electricity use by 21 percent and save $7.3 billion by 2020 if utilities ramp up energy-efficiency incentives, a public policy group said Tuesday.

 

"The report found that every dollar invested in energy efficiency returns more than $2 in savings on business and household utility bills."

 

"The 270-page report calls for $5.5 billion in investments in efficiency programs by Arizona utilities, money that Geller said the companies would have to spend anyway on things like new power plants to keep up with demand."

 

"Geller’s study said the energy saved would allow Arizona to avoid building or close 10 large power plants..."

Duane Tildens insight:

"More from the IEEE Smart Grid/Zpryme report on energy storage: top-rated benefits are meeting peak demand, improving power reliability and reducing costs. Hurdles: costs, deployment and a lack of standards. Lithium-ion will see the most demand over the coming five years. Respondents think North America will see the most growth in lithium-ion-based storage in that period. Where's the money? Respondents think government-backed R&D, industry R&D and private/venture capital will provide it. (See last week's column, "Electric Vehicles: Looking Back, Looking Forward, Part II," for a new public/private partnership on R&D for energy density in batteries.) "

Duane Tildens insight:

I have seen new materials developed and installed in other situations which ultimately fail as they have yet to undergo the test of real life conditions and are poorly installed. 

 

Ideally prepared test samples which manufacturer's base data and promotional materials can be misleading regarding performance in the field.  Temperature and humidity at time of installation may play an important factor in the performance of the material over time as an example.

Duane Tildens insight:

"The Global e-Sustainability Initiative (GeSI), an information and communication technology (ICT) industry partnership, just released a new report that details how expanded use of ICT could cut global greenhouse gas (GHG) emissions by 16.5% by 2020 and offset $1.9 trillion in gross energy and fuel costs. ...  Unsurprisingly, the power and transportation sectors, respectively, are found to have the highest potential for GHG emission reduction via greater ICT adoption. But the report also finds agriculture – even more so than manufacturing or the consumer and service sector – to be an area with significant potential for greater energy efficiency."

Duane Tilden's curator insight, December 13, 2012 6:09 PM

"Fuel cells, solar thermal generating stations, photovoltaic fields, wind farms, diesel, natural-gas-fired turbines, microturbines and other renewable and non-renewable sources of energy can be aggregated in a microgrid..... a microgrid could automatically detach from the greater grid and continue to deliver power to sectors of customers in abnormal conditions. And this would enable utilities, too, to more strategically and efficiently deploy resources to damaged areas of the grid to make repairs and restore service."

ARPA-E Bets $130 Million On Cutting-Edge Green Tech - Forbes | Green Energy Technologies & Development | Scoop.it
Financial support from the U.S. government seems more critical than before now that many venture capital firms are shying away from investing in green tech. But be forewarned: those public money investments could take a long time to bear fruit.

 

"1. Better magnets: Electron Energy in Pennsylvania is due to receive $2.9 million to come up with better magnets that don’t require rare earth materials and perform better than what are being used to make the motors in wind turbines and electric cars today. Rare earth mining isn’t environmentally friendly and is concentrated in China, which has restricted rare earth export in the past. ARPA-E has previously funded projects for developing rare earth-free magnets and motors."

 

"4. Power plant efficiency: The University of North Dakota will use $472,580 from ARPA-E to develop an air-cooling equipment to help power plants run efficiently. Fossil fuel power plants require a lot of water to operate. The research will use an “air-cooled adsorbent liquid” that releases moistures to keep the power plant cool and minimize water losses."

Deregulation essential for energy plan: Origin

Deregulation essential for energy plan: Origin | Green Energy Technologies & Development | Scoop.it
Updated | Prime Minister Julia Gillard’s energy plan cannot succeed unless state governments agree to deregulate retail prices and roll out smart meters, power company Origin says.

 

"Ms Gillard announced five proposals on Sunday which she said were designed to curb electricity price rises and could save households $250 each a year.

 

They include:

■ Reducing incentives for state-owned distributors to over-invest in poles and wires by speeding up implementation of the Expert Panel Review of the Limited Merits Review Regime and developing national reliability standards;

■ Creating a Consumer Challenge Panel with the energy regulator to advocate for energy users and setting up a national consumer advocacy centre;

■ Spending an extra $23 million a year on the Australian Energy Regulator;

■ Urging state governments to introduce time of use pricing and roll out smart meters;

■ Urging state governments to deregulate retail prices.

Origin spokesman Phil Craig welcomed time of use pricing but said two critical elements were missing: full retail price deregulation and a full commitment and schedule for the roll out of smart meters.

 

“The right things are being said, the challenge is: in what time frame are we going to see state governments fully deregulate retail prices?” ..."

OEE: A Controversial Figure | Automation World

OEE: A Controversial Figure | Automation World | Green Energy Technologies & Development | Scoop.it
This performance metric takes center stage as a growing number of users turn to it both to boost the efficiency of their equipment and to compare the performance of machines and production lines.

 

"OEE is a measure of the utilization of an asset’s productive capacity in terms of three factors—availability, performance (throughput), and quality—expressed as percentages of their ideal values. For example, performance is the actual production rate or throughput expressed as a percentage of the designed capacity of the equipment."

 

"...OEE can sometimes be useful for comparing identical and nearly identical equipment, ... the metric is not always suitable for this purpose. ... OEE is the product of only three factors: performance, quality and uptime. “It doesn’t factor in things like sales and the importance to the business,” he says. “Those are things that OEE just doesn’t have any kind of theoretical basis to address.”

 

"For this reason, comparing equipment often makes more sense with other metrics, such as the total effective equipment performance (TEEP), the product of OEE and a loading factor computed by dividing planned uptime by calendar time...."

 

"Users often neglect this loading factor when comparing lines. ... The client never planned to run the lines for the same amount of time each day,” he says. So, he maintains that it was unfair to compare their OEEs."

 

"Another limitation of OEE, as well as TEEP, is that the metric does not consider sales and the relative contribution that a machine or line makes to the overall business. “You have to factor in the return on investment,” says Kemmann. “If similar lines with different OEEs are serving different customers where your pricing structure is different, then comparing OEEs will not be helpful because you’re not factoring in the effects of their relative value to the business.”"
