Renewable Energy or Efficiency for the Data Center: Which first? #GreenComputing

See on Scoop.itGreen & Sustainable News

New advancements in green technology and design are making the idea of a green data center into a reality.

Duane Tilden‘s insight:

>Without doubt, the facility is a triumph of advanced environmental design and will serve as a template for future construction. Indeed, activity surrounding renewable-based data infrastructure is picking up, with much of it being led by the burgeoning renewable energy industry itself. VIESTE Energy, LCC, for example, has hired design firm Environmental Systems Design (ESD) to plan out a series of data centers across the U.S. that run on 100 percent renewable energy. A key component of the plan is a new biogas-fed generator capable of 8 to 15MW performance. The intent is to prove that renewables are fully capable of delivering reliable, cost-effective service to always-on data infrastructure.

The question of reliability has always weighed heavily on the renewables market, but initiatives like the VIESTE program could help counter those impressions in a very important way, by establishing a grid of distributed, green-energy data supply. In fact, this is the stated goal of the New York State Energy Research and Development Authority (NYSERDA), which has gathered together a number of industry leaders, including AMD, HP and GE, to establish a network of distributed, green data centers that can be used to shift loads, scale infrastructure up and down and in general make it easier for data users to maintain their reliance on renewable energy even if supply at one location is diminished. In other words, distributed architectures improve green reliability through redundancy just as they do for data infrastructure in general.

But not everyone on the environmental side is convinced that renewables are the best means of fostering data center efficiency. In a recent article in the journal Nature Climate Change, Stanford researcher Dr. Jonathan Koomey argues that without populating existing infrastructure with low-power hardware and data-power management technology first, data operators are simply wasting precious renewable resources that could be put to better use elsewhere. For projects like the NWSC and VIESTE, then, renewables may make sense because they power state-of-the-art green technology. But not as an industry-wide solution–renewables won’t make sense until hardware life cycles run their course.<

UK Shopping Centre goes zero Waste to landfill in a year

See on Scoop.itGreen & Sustainable News

As a new member of the National Recycling Star scheme, Clifton Down Shopping Centre received the Gold award for its recycling and waste management efforts and in recognition of its success in diverting all of its waste from landfill.

Duane Tilden‘s insight:

>The transformation in the centre’s waste management began with a full site audit to identify areas of poor practise within both its waste management and energy efficiency operations.  […]

As the shopping centre began to look at improving its waste management plan, it asked its tenants to start flat packing their waste cardboard, so it can be sent to the centre’s onsite compactor. Pre-flat packing waste cardboard has allowed the centre to double the amount of cardboard that can be collected by its waste contractor Smiths, while saving space in the services yard. This has cut the number of collections required, helping to save fuel consumption and CO2 emissions. All general waste produced by the shopping centre is sent to New Earth Solution’s mechanical biological treatment (MBT) facility at Avonmouth.

Clifton Down Shopping Centre has also been working to reduce its environmental impact by tackling its energy efficiency. New LED light fittings have been installed throughout the shopping centre, significantly reducing energy consumption and cost. The centre previously used old halogen lighting which consumed 14,994kW per annum, compared with the replacement LED lighting which consumes 2,998kW – an 80 per cent reduction. […]

The centre has also installed seasonal sensitive automatic doors at both entrances. These are programmed to close more quickly during winter months to minimise heat lose. This is switched during summer with doors remaining open for longer, allowing for cooler air to circulate the building. New electricity, water and gas monitors have been installed throughout the centre to measure consumption and identify areas of potential savings.<

Innovations in waste water treatment processes to provide clean energy

See on Scoop.itGreen Energy Technologies & Development

The race is on to develop innovative, cost-effective ways to extract value from waste water instead of just dumping it, writes Sadhbh Walshe

Duane Tilden‘s insight:

>In a conventional treatment process, ammonia is converted back into nitrogen gas, a non-harmful gas which can be safely released into the atmosphere. The conversion process is expensive, however, and energy prohibitive.

What the Stanford team do, instead, is to use a less energy-intensive process to convert the ammonia into nitrous oxide (N2O), a powerful substance that is typically used to turbo-boost cars or fire rockets.

Normally, N2O is discouraged from forming because it is a harmful greenhouse gas, but when it is burned along with methane it becomes an energy source that can be used to power the treatment facility. According to Scherson, there is a double energy-saving benefit.

“Our process reduces energy input in nitrogen treatment and then the energy from nitrous oxide can potentially be used to power the plant making it energy neutral or even energy positive.”<

Cambridge Plans Massive Energy Efficiency Retrofit

See on Scoop.itGreen Building Design – Architecture & Engineering

This medieval English city is investing $1.5 billion for energy upgrades for the entire city.

Duane Tilden‘s insight:

>It’s one thing to build super-energy-efficient new homes and offices – it’s another matter entirely to bring ancient buildings up to par. But the medieval university city of Cambridge, England, plans to do just that with a $1.5 billion retrofit program.

The newly launched Cambridge Retrofit Project aims to reduce carbon emissions from buildings 30% before 2050 through a massive, city-wide retrofit scheme.  […]

While the primary goal is reduced energy consumption and carbon emissions, the program also aims to build up local businesses, create warmer homes and increase the value of properties.

Energy savings alone are expected to be worth $2.3 billion and the city’s carbon footprint, currently 830,000 tons a year, is expected to fall 1% a year, eventually reaching 500,000 tons a year as a result of the retrofit program.<

Green Building Taking Off in Hospitality, Retail Industries

See on Scoop.itGreen Building Design – Architecture & Engineering

Green building is taking off in the hospitality and retail industries, […]  This year, retail owners that are building green for over half of their projects rose to 38%, up from just 18% in 2011. That’s expected to rise to 52% by 2015.

Duane Tilden‘s insight:

>”Green building has taken such hold in the industry that even sectors with unique challenges, such as retail and hospitality, are making stronger investments,” says Harvey Bernstein, vice president at McGraw Hill Construction. “Clearly the benefits that owners are reporting are key reasons for their green building investments, and as they find better ways to measure those impacts and quantify the value to their sales velocity and to the well-being of their staff, customers and guests, we expect even more rapid engagement in green.”

While lower operating costs are the most frequently reported reason for going green (66% of retailers, 73% of hotels), other factors are also considered very important in their decision-making process:

Utility rebates – Protecting/enhancing brand – just as important as costs for hotels

Improving ROI  […]Energy efficiency is still a key goal, recycling and waste management are also critically important. A strong majority say they require green practices from suppliers, especially on waste handling (75%). <

Water kit to be added to JEA home evaluation program – Jacksonville Public Libraries

See on Scoop.itGreen & Sustainable News
The popularity of JEA’s Home Energy Evaluation Kit Backpack program has spurred the utility to add a water-use evaluation kit to the tools offered to homeowners to help them reduce their utility bills

Duane Tilden‘s insight:

>The kits have been checked out 2,143 times since the pilot program started in 2010.  The backpacks are available at all Jacksonville public libraries and the Bartram Trail Library in St. Johns County, because it is in the JEA service area.

“Prior to the backpack program, customers would have to schedule an appointment with a technician who would visit the home, but the backpack allows them to get started with conservation on their own, … The hardest part about developing the kit was the instruction manual, … “We wanted to make sure it was functional, yet understandable,” said Reed.

Kits can be checked out for three weeks and are available on a first-come first-served basis, unless customers attend a JEA workshop.<

Waste Management’s Hidden Value Driver Doesn’t Stink – DailyFinance

See on Scoop.itGreen Energy Technologies & Development

One thing has plagued mankind from the very first man caves tens of thousands of years ago to the streets of modern day cities: waste. Where do you

Duane Tilden‘s insight:

>Waste Management has quietly become a leader in waste to energy (WtE) and landfill gas to energy (LGTE) technologies. […] The company, using various sources of waste as feedstock, generates up to 550 MW of renewable energy each year – enough to power almost 1.2 million homes. Internal goals call for increasing that figure to 915 MW (2 million homes) by the end of the decade.

Waste to energy

Waste Management’s waste to energy services ignite solid and municipal waste to produce syngas, which is burned to spin turbines and, alas, create renewable electricity. Wheelabrator, the company’s subsidiary, operates 17 WtE facilities in the United States that can convert over 8 million tons of waste into 333 MW each year. That is second only to Covanta, which owns 44 facilities that convert over 20 million tons of waste into 9 million MWh of electricity each year – equivalent to 8% of all renewable energy in the United States.<

GE Gas Engines to Power Alternative Energy Projects

See on Scoop.itGreen Energy Technologies & Development

GE to Supply Jenbacher J620 Engines to Power GWED’s Waste-to-Energy Projects – […] to power a series of Advanced Recycling and Energy Conversion (AREC) plants that GWE’s development subsidiary, Green Waste Energy Development (GWED), plans to build around the world.

Duane Tilden‘s insight:

>GWED uses C6 Technologies’ proprietary and patent-pending, non-burn waste-advanced pyrolysis technology in its AREC projects. The C6 technology can transform a wide range of wastes into “syngas,” which then can be used in gas engines to generate cleaner electricity or produce greener transportation fuels including diesel and jet fuel. C6T licenses its technology to developers worldwide.

Under terms of the agreement, GE will provide GWED with Jenbacher J620 gas engines, which will use the syngas produced at GWED’s waste-gasification facilities to generate renewable electricity. Each installed gas engine will generate nearly 2MWof reliable on-site power. GE also will provide technical support for GWED’s installed engine fleet.<

Plastic bottle recycling exceeds 50 per cent | Resource magazine

See on Scoop.itGreen & Sustainable News

New data from a national charity RECycling of Used Plastics Ltd (Recoup), has found that 70 per cent of the 610,000 tonnes of plastics packaging recycled in 2011 came from domestic kerbside collections.

Duane Tilden‘s insight:

>Future outlook

The Department for Environment, Food and Rural Affairs (Defra) has issued yearly targets for businesses concerning the recycling of paper, glass, wood, steel, aluminium and plastics for the period 2013-2017. Although the targets for most of these materials remain static or see only slight increases, the targets for plastic recycling increase by five per cent each year.

This means the plastic recycling target for 2017 is 57 per cent – up from 32 per cent in 2012 – a figure that the British Polythene Industries (BPI) plc has warned is ‘unachievable’.<

Norway: A recycling-happy nation in dire need of trash

See on Scoop.itGreen & Sustainable News

Sweden isn’t the only nation in the throes of a serious trash deficit. As it turns out, Norway is also desperately seeking rubbish to burn in its cogeneration plants. Perhaps the U.S. could lend a helping hand?

Duane Tilden‘s insight:

Excerpts…

Norway’s garbage woes aren’t an anomaly in Scandinavia and across Northern Europe where the demand for trash to fuel garbage-burning incinerator plants is high but the supply is devastatingly low due in part to residents’ pertinacious recycling habits. In fact, Northern European countries only produce 150 million tons of trash annually, while the overall capacity of incinerating plants is 700 million tons and growing.

[…] While the burning of garbage is not an environmentally flawless method of producing energy, modern day cogeneration plants are relatively high-tech affairs and the pollution generated is far less than coal. This method also renders landfills nearly irrelevant.
