Context

• Our Energy Challenge (dti 2006)
• Potential for microgeneration (EST 2005)
• Small wind can provide 4 of UK electricity needs
• About 20 MW for Cornwall
• Low Carbon Buildings Programme (dti 2006)
• Stream 1 50 intervention rate, first come
  first served

Barriers

• Skills gap
• Accreditation schemes can act as a barrier
• Inequitable price for exported electricity
• Planning
• Lack of information
