Path to a Net-Zero Mad River Valley 1. Calculate existing loads
2. Estimate load reduction 3. Estimate renewables needed to meet load 4. Evaluate changing infrastructure for further reduction
TOTAL ENERGY LOAD: 166,000,000 – 476, 000,000 kWh or 567,000,000 – 1,625,000,000 kBtus
With energy conservation we can realistically expect to reduce energy loads by around 25%. We would then need: 132,000 barrels of oil
55,000 cords of wood, 55,000 acres of woodland 192,300 kW of installed PV, 1150 acres or 1.8 square miles 27 wind turbines (2.3 Mw with 100 meter blades) assuming a wind speed of 7.5 mps, requiring ridgeline placement
