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 Eco-schools work
• There are lots of local examples and good news stories to make the topics tangible and relevant
Observed TrendsDomestic: 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 PC power down settings are saving enough electricity to power the Manx Electric Railway and the Snaefell Electric Railway

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

Renewables in use in IOM
• Hydropower• Heat Pumps (GSHP, ASHP)• Solar Hot Water• Micro-wind• Biomass
• EfW• 15% RE by 2015 Target

UK Crown Estate – Offshore Wind
• Zone 9, to our SE is licensed for over 4GW capacity in 2,200km2 zone, enough to supply ~3,000,000 homes
• Current IOM MEA Generation capacity is 0.18GW
• IOM territorial waters are 4,000km2, land area 600km2
• Scope for development in IOM waters, for which developers pay “seabed rental”
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 2009).
• TTXGP, zero emission motorbike class
Climate Change - Adaptation
• We can mitigate against Climate Change, but also need to adapt to what’s already in train
• Infrastructure• Buildings• Wildlife• Businesses
Energy/Climate Resources
• Lots of published resources and links including lesson plans

IOM Energy/Environment Data• 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
