Geothermal Energy

7

Provides clean renewable energy

Proves a steady and reliable source of energy 24 hours a day, everyday

EPA has identified over 750,000 geothermal systems in USA

Geothermal Energy - Design Can provide 70% of max heating load (75kW)

Supplemental heat supplied by high efficiency furnace

Closed loop system with 5 heat pumps (15 kW each)

Vertical arrangement, drilling depth – 30 m

Combined geothermal system with reinforced insulation – increasing our savings

Government grant available - up to 10% of total cost for new geothermal installations

Solar Power Total active area installed: 2,185 m2

kWpeak installed: 219.9 kW

Total installed cost of solar modules: $1,475,394.80

Angle of solar cells to horizon: ~41°

Wind Power

Selected windmill model:

WTIC 31-20

Total number of windmills installed: 10

Total installed cost of windmills: $339,000

Biogas Generation

Releases CO2 but considered neutral

Reduces landfill tipping fees

Calculations based on industrial case studies

30 kW produced from 430 kg/day

Stirling Engine
