CLEAN ENERGY COMPARISON AND SENSITIVITY WORKSHEET

PURPOSE
Compare eligible energy proposals for a stated service. Preserve raw
evidence, units, source dates and uncertainty. Use weights only after
checking essential requirements. This worksheet is a decision aid,
not a universal technology ranking.

SERVICE AND ELIGIBILITY
Location and delivery point:
Required service (electricity, heat or other):
Annual energy and units:
Critical hours / peak requirement / reliability requirement:
Decision period and required delivery date:
Existing grid, generation, storage and flexible loads:
Land, water, permitting and other essential constraints:
Option A and eligibility evidence:
Option B and eligibility evidence:
Unresolved requirements and responsible person:

EVIDENCE (repeat for each option)
Lifecycle greenhouse gases per unit of delivered service:
Study boundary, lifetime and capacity factor:
Air pollutants, location and affected populations:
Land and ecosystem impacts:
Water withdrawal and water consumption separately:
Materials, waste and available recovery route:
Cost, currency year, financing and included/excluded items:
Connection, balancing, replacement and decommissioning provisions:
Contribution during relevant demand/stress periods:
Source / edition / date / uncertainty for each field:

WEIGHTED COMPARISON
Define scoring anchors before assigning scores (for example 1 to 5,
with 5 preferred). Retain underlying measured or estimated values.
Criterion / weight / A score / B score / supporting evidence:
Weights must sum to 1 (or 100%).
Weighted score = sum of score x weight over all criteria.
Essential requirements remain separate from preference scoring.

FICTIONAL EXAMPLE
Criteria: climate, cost, delivery time.
A scores 5, 3, 2. B scores 3, 4, 5.
Weights .50, .30, .20:
A = 3.8; B = 3.7.
Weights .30, .30, .40:
A = 3.2; B = 4.1.
These invented scores describe no named technology.
The changed preference shows sensitivity to the chosen priorities.
Do not treat a small score difference as decisive when inputs overlap.

SENSITIVITY AND DECISION
Alternative plausible weights:
Lower-performance or higher-cost cases:
Does the preferred option change?
Which uncertainty could change eligibility or the recommendation?
Who chose the weights and why:
Decision / tradeoffs / unresolved evidence:
Next evidence to obtain and assigned owner:
Trigger for reassessment:
Keep generation-only metrics distinct from the cost and impacts of
delivering the complete required service.
