BT aims to shave £13 million a year
off its energy bills and reduce its
carbon footprint by 5% or 60,000
tonnes by introducing a smart
energy management system across
its offces, telephone exchanges and
data centres.
In the 2010/11 fnancial year, BT
used 2,342GWh of energy running its
UK networks, data centres and offces,
equivalent to 0.7% of all the electricity
consumed in the UK.
BT is currently installing more
than 22,000 smart energy meters,
more than 1,500 building energy
management systems and an advanced
control network over broadband that
will enable it to monitor and control
more than 90% of its UK energy
consumption.
The integrated energy management
system will receive data from smart
meters, invoices and building energy
management and control systems,
enabling BT to monitor energy use and
identify where savings can be made.
For example, benchmarking Power
Usage Effectiveness (PUE) across BT
buildings will help BT identify the best
and worst performing locations and
implement actions to improve energy
effciency.
In 2012, BT plans to implement
similar energy management systems
globally. BT has a commitment to
reduce its carbon intensity by 80%
by 2020 (compared to 1997 levels)
and to generate 25% of its UK energy
needs from renewable energy sources
by 2016.
Following the successful trial of its
paper milk bottles in Asda stores
in the South-West of England,
GreenBottle is expanding its range
with the introduction of a paper
wine bottle that it is marketing to
supermarkets and wine producers.
The prototype is designed along
the same lines as the company’s milk
bottles i.e. with a tough paper casing
around a thin plastic bag containing
the liquid.When the bottle is empty,
the user tears off the paper for
composting or recycling and puts the
plastic bag in the household rubbish
or plastic recycling stream.
Green bottle inventor Martin
Myerscough says that a GreenBottle
uses less than one third of the plastic
of a conventional plastic milk bottle
and has just one tenth of the carbon
footprint of a glass wine bottle.
Myerscough adds that the results
of Asda’s six month trial indicate that
consumers understand the concept:
sales of milk sold in GreenBottles
more than tripled compared to
sales in conventional plastic bottles;
and 80% of consumers who tried
GreenBottles said they prefer them to
plastic ones.
GreenBottle, which sold its
100,000th paper milk bottle last
month, is close to unveiling new
machinery that will enable it to
create GreenBottles more cheaply
and in industrial quantities.

Natural cooling
Internet service provider CCS has installed an
Eco Cooling air conditioning system as part of
a £150,000 investment in its new 4,800 server
capacity datacentre in Leeds. The air conditioning
system, part-funded with a £36,000 grant from
the Carbon Trust, harnesses the natural process of
evaporation and, unlike traditional air conditioning
systems, uses clean fresh air, which allows odours
and bacteria to be expelled naturally. In operation,
the coolers use just 240v of electricity, the same as
a domestic electric fre.

Saved by the cloud
Large UK companies that use cloud computing could, by
2020, achieve annual energy savings of £1.2 billion and
carbon reductions of 9.2 metric tons, equivalent to the
emissions of over 4 million passenger vehicles, the Carbon
Disclosure Project (CDP) claims. New analysis included as an
addendum to the report Cloud Computing: The IT Solution for
the 21st Century shows that if large UK companies accelerate
adoption of cloud computing from 10% to 70% of IT spend
by 2020, as forecast, they could reduce CO2 emissions
associated with their IT estate by 50%. The claim is based
on an analysis of 457 UK frms with revenues greater than
$1billion by Verdantix. www.cdproject.net
HP on top
HP tops the rankings in the latest Greenpeace Guide to
Greener Electronics, which rates 15 consumer electronic
companies across three areas: Energy, Greener Products and
Sustainable Operations. The 17th edition of the guide includes
new assessment criteria relating to renewable energy use;
supply chain carbon footprints; product lifecycle; confict
minerals; and the sourcing of paper.

Waging war on pixels
PretonSaver, which like Tonermiser (see page 20) can reduce
a printer’s use of toner by up to 50%, is being deployed
by Korea’s Hana Bank to cut annual consumables costs by
25%. The bank is deploying the Enterprise version in its
Seoul headquarters and more than 600 branches to control
the printing of customer transactions, external reports and
internal reference material. PretonSaver uses Preton’s Pixel
Optimizer technology to remove unnecessary pixels without
impacting print quality and confgurable print rules and
policies to reduce paper consumption. www.preton.com
