Policy Commitment:
Reducing energy and resource consumption by implementing efficiency measures consistent with best practice, over cost-effective timescales

Environmental Management Programme Objective:
To Reduce Energy Use Across The Estate And Seek Supplies From Renewable Sources

3.1 Introduction to the Issue
We currently use energy in the form of gas, electricity and standby generation fuel oil.  Generation of electricity from burning non-renewable fossil fuels produces greenhouse gases (most notably carbon dioxide) and other harmful gases (which may have adverse health effects).  A significant majority of scientists, most notably the Intergovernmental Panel on Climate Change (IPCC) cite the emission of greenhouse gases from the combustion of fossil fuels as the main contributor to climate change.  By reducing energy use and by making energy use as efficient as possible, these emissions can be reduced, preventing further damage to the environment through the depletion of fossil fuel resources and the impacts of climate change.
The Climate Change Levy (CCL) came into force in April 2001. This tax aims to encourage more efficient use of energy and to assist the UK to meet its reduced greenhouse gas emission commitments under the Kyoto Agreement. All energy supplied to industrial and commercial users is subject to the levy and therefore it appears as an additional charge on our utility bills, charged at different rates according to the type of energy source used.
There are opportunities to reduce gaseous emissions and energy costs through specification of more efficient heating, lighting and cooling and premises management systems and IT equipment.  Increased staff awareness and training is vital to realise reductions.

3.2 Current BSkyB Status
We currently use energy in the form of gas, electricity and standby generation fuel oil.  Our main sources of energy consumption within BSkyB are:

Consumption area	Energy Efficiency Actions
Heating, lighting and cooling systems.	Some energy efficient lighting has been installed across the sites and opportunities for further installation is actively considered as part of the maintenance and replacement programme.
IT systems and equipment (PCs, copiers, faxes, printers).	Power down facilities are specified and IT are ensuring that it enabled as a default at all locations.
Broadcasting studios	Use of studios can be 24 hours.  The opportunity to use energy efficient lighting is being explored; however, there are concerns about its applicability to studio.  This is being reviewed.
Satellite Uplink Sites and Communication Infrastructure	Transmitting/receiving equipment uses considerable energy and produces waste heat, which can sometimes be reused - see the case studies below.  Technological advances have meant a move from single signals down one cable (fibre optic) to multiplexed cables.  We have worked with BT to convert from copper infrastructure to fibre optics which are more energy efficient and have environmental benefits (such as reduced excavation due to fewer cables, reduced use of outside broadcast trucks). The move from analogue to digital systems will reduce the use of such lines, and hence the environmental impacts, in the future.
Call centres	There is a large energy demand from the IT systems as well as for heating our customer service halls.  There has been major refurbishment of the call centres in Scotland and energy efficiency measures have been incorporated as far as possible.There will be a move from 150 to 50 watt desk-tops PCs over next 2 years which will also cut energy consumption once currently tandem duplicated systems are replaced.
Editing suites	Editing suites (which contain heavy, expensive, energy intensive equipment) will be reduced in number in the future as editing can now be done offline via a PC.
Our Consumer Products	Careful product specification has a role to play in reducing energy use of our products, particularly set top boxes - see under Consumer Products, later.

An energy audit was carried out in 2000 by Energen Management, looking at efficiency issues, cost savings and the implications of climate change levy.  The findings of this audit are being considered as part of developing a coherent approach to energy management at the sites.  This will be built into actions taken over subsequent years to address this issue.

We have calculated the impact of the climate change levy, which is being tracked by a national centre which manages the tariffs for the company and the implications are being considered .

We are also seeking to rationalise the number of energy suppliers (three electricity suppliers and two gas suppliers) across the estate to improve the quality of data streams.

3.3 Current Performance Data
Energy data is shown below for the first quarter of the 2001/02 year.  This information represents the first complete data set from the monitoring and reporting processes instituted at the beginning of the financial year.

However, it should be noted that historical information is available for some sites in considerable detail.  For example, data sets are available for electricity, gas and oil consumption since 1990 for our Chilworth site.

The following information is provided for the sites that make up at least 90% of our business.

3.5 Case Studies/Interesting Facts

Optimising energy use
Amplifiers and antennas are key technical components in signal transmission and reception.  However, amplifiers are energy intensive and generate a lot of waste heat.  In winter, the performance of antennas can be affected if they become iced.  This issue was identified as one presenting an opportunity for improvement.  In consequence, equipment has been installed so that amplifier heat could be used to heat antennas in winter to prevent the antennas from icing over.  This is in preference to previous approaches which used gas heaters to prevent them from icing over.

We have also exerted pressure on existing amplifier manufacturers to incorporate power save features to reduce the energy consumption of our amplifiers, which reduces our energy consumption and in consequence our contribution to global warming.
