Context
• Department of Education and Children has made
major improvements in energy efficiency and
reducing its CO2 emissions in recent years, but it
still spends ~£2m on electricity and heating
schools each year
• Energy and issues linking to Sustainability can link
well to many areas of curriculum study and Ecoschools work
• There are lots of local examples and good news
stories to make the topics tangible and relevant
Observed Trends
Domestic:
 Domestic energy consumption has increased gradually along with the rise in the number of
households.
 According to the House Condition Survey (2007/2008), there have been significant improvements in
domestic energy efficiency between 2002 and 2008.
 Considerable scope still exists for insulation improvements including loft and wall insulation and
draught-proofing.
Government:
 Energy use by the Government sector has increased significantly, however has recently started to
level off.
 Energy usage peaked in 2005/2006 reaching 171GWh, however dropped to 164GWh in 2008/2009.
 Principal reason for growth in energy usage has been the growth in infrastructure and building
ownership under Government, therefore increasing demand by Government estates.
 Net government emissions are down 16.5% since 2004/5
Commercial
 There is significant scope for development in this sector.
 Between 1996 and 2005 energy usage increased by nearly 100GWh
 Energy demand expected to remain stable for next few years, then expected to increase as the DTI
will be targeting industry much more intensely, including attending some major industry trade shows
to promote the Island as a base for businesses, including Clean Tech as a business sector

NSC – Energy Projects
• Optimised power station heat recovery and smarter
control systems have saved over £150,000 per year
Energy Projects – Power down Settings
• Changes to Government

Woodchip
• DEFA Plantations cover
3,000 hectares
• This could supply over
10,000 tonnes of woodchip
each year
• Cost effective and fully
sustainable

2,200km2 zone, enough to
supply ~3,000,000 homes
• Current IOM MEA

Clean Tech – test bed
• DED is promoting IOM as
location for R+D of new
clean-tech businesses
• over 40 clean tech
companies, 8 listed on
AIM. Collective valuation
>£800,000,000 (Aug

IOM Grid electricity is significantly less carbon intensive than UK. How could it
improve further?
Pro’s and Con’s of renewables: Wind (On/Off shore), Biomass
Pro’s and Con’s of an Energy from Waste plant. Impact on recycling, avoided
methane emissions?
There are many Clean Tech Businesses registered in the Island. Would it be a good
“target market” to expand?
Homes are getting more and more energy efficient. What should houses look like
in the future?
Create an Energy Benchmark for your school, how does it compare to other
schools?
Create a Green Travel Plan for your school, how would you measure its success?
There are Climate Change scenarios projected for the Isle of Man in the 2050’s and
2080’s at www.ukcip.org.uk . What Climate Change Adaptation measures should
we be thinking about now for:
– Homes and Buildings
– Roads and Infrastructure
– Farming and Wildlife
