Right sizing energy
• Energy balance needed
• Appropriate use of energy
– Do we really want to heat a house with a nuclear breeder reactor?
– Do we really want to run a steel mill with wind mills?
![Page 8: Kufstein 2010 Gespraeche 2a Email](https://reader035.vdocuments.net/reader035/viewer/2022062614/5478ff43b4af9f01228b45c2/html5/thumbnails/8.jpg)
D E R• De-Centralized Energy Resources
– Possible Energy Sources:• Combined heat power (CHP)• Micro combined heat and power (MicroCHP)
– Wood, Biomass, Cut grasses, etc.• Microturbines• Solar
– Thermal, Hi/Lo Temp, Stirling engines– Photovoltaic Systems
• Small, large Wind power systems• Reciprocating engines
– Cogen, Trigen• Fuel cells

Microgeneration manifesto
• GHG reduction requires widespread and systematic incorporation of microgeneration technologies into both new and existing buildings
• Carbon savings aside, spin-off benefits include: – greater energy security, – alleviation of fuel poverty – contribution towards the economic recovery through the
creation of ‘green jobs’
• The key pillars of Microgeneration Manifesto are: – cohesive, integrated financial support– comprehensive retro-fitting of microgeneration
technologies into existing building stock; – clear information on options for credible career options.

12 Permaculture Principles1. observe and interact2. catch and store energy3. obtain a yield4. apply self-regulation + accept feedback5. use and value renewable resources + services6. produce no waste7. design from patterns to details8. integrate rather than segregate9. use small and slow solutions10.use and value diversity11.use edges and value the marginal12.creatively use and respond to change

Permaculture Zones (energy zones)
0 = where we live
1 = our garden, property
2 = the surrounding forest, community
3 = the larger support , farms
4 = harvest forests
5 = natural conservation forests
6 = office, shop, factory
