TEWF Way Forward
Based on the approval of the recommendations:
 UCH staff to implement low cost energy
efficiency options – next 6 months
 UCH staff to undertake solar dish cooker
demonstration
 TEWOAF to obtain funding for
Energy efficiency program (AUD 5,600)
 Sustainable energy program (AUD 50,000)

EWB Way Forward
Once TEWOAF funding obtained:
 Procure sustainable energy products
 6-12 month implementation volunteer
 Volunteer to implement projects and train staff
