It looks like you’ve got a great activity. Below I’ve turned it into a ready-to-use teacher package: a student worksheet/step-by-step guide, a worked example (with simple numbers and calculations you can adapt to your local area), a spreadsheet template description (so students can calculate outputs, costs and emissions), a rubric, presentation tips, and extension/differentiation suggestions.
Use as-is or copy/paste into your LMS or document editor and adjust numbers to your locality.
1) Lesson overview (teacher)
- Goal: Students design a locally realistic sustainable energy plan using scientific evidence: energy potential, cost, emissions, reliability, and social/economic impacts.
- Grade level: middle-high school (adaptable).
- Time: 2–4 class periods (Research & calculations, Plan design, Presentation).
- Grouping: Small groups (2–4 students).
- Materials: local energy data (or teacher-provided data), internet, calculator or spreadsheet, chart paper or presentation software.
2) Student worksheet / step-by-step (handout)
Part A — Research (collect data for each energy source available locally)
For each source (e.g., rooftop solar, utility-scale solar, onshore wind, hydro, natural gas, coal, biomass):
- Estimated technical potential (MW or km2 and/or annual MWh)
- Typical capacity factor (decimal, e.g., solar 0.20)
- Cost per kWh (LCOE or local retail cost) $
- CO2 emissions factor (kg CO2 / kWh) (lifecycle or operational)
- Reliability/availability and seasonal patterns (peak vs. off-peak)
- Land and social constraints (land use, noise, visual, water use)
Part B — Spreadsheet table to complete (columns)
- Source name
- Proposed capacity (MW)
- Capacity factor
- Annual generation = capacity (MW) * 8760 * capacity factor (kWh or MWh)
- % of total energy supplied = annual generation / city demand
- LCOE ($/kWh)
- Annual cost = annual generation * LCOE
- Emissions factor (kg CO2/kWh)
- Annual CO2 = annual generation * emissions factor
- Reliability/notes (short text)
Part C — Design your plan
- State total local annual electricity demand you are planning for (kWh/year).
- Propose a percent mix (and capacities) of energy sources.
- Show calculations from Part B for production, cost, emissions.
- State supporting reasons: resource availability, cost, environmental impact, reliability.
- Include short recommendations for: storage (battery/hydrogen/pumped hydro), demand response, grid upgrades, timeline, and community/social measures.
Part D — Short presentation/report (3–5 minutes)
- 1 slide/page: summary of proposed energy mix and key numbers (annual generation, annual cost, annual CO2, percent renewables).
- 1 slide/page: defenses: why sustainable, how it reduces emissions, economic feasibility, social impacts and mitigation.
- Be ready to answer: feasibility, land use, intermittency, who pays, how jobs are affected.
3) Spreadsheet template: formulas and guidance
Columns and formulas (example row for Solar):
- Capacity_MW (enter) e.g., 50.0
- CapacityFactor (enter) e.g., 0.20
- AnnualGeneration_MWh = Capacity_MW * 8760 * CapacityFactor / 1 (result in MWh)
- LCOE ($/kWh) enter e.g., 0.04
- AnnualCost = AnnualGeneration_MWh * 1000 * LCOE
- EmissionsFactor_kg_per_kWh enter e.g., 0.05
- AnnualCO2_tonnes = AnnualGeneration_MWh * 1000 * EmissionsFactor_kg_per_kWh / 1000
(Use similar rows for each source. Sum AnnualGeneration, AnnualCost, AnnualCO2.)
4) Quick worked example (fictional town “Riverton” — adjust numbers for your area)
Assumptions:
- Population: 50,000
- Annual electricity use per person: 4,000 kWh → Total demand = 200,000,000 kWh = 200,000 MWh/year (200 GWh)
Proposed mix:
- Solar 45% → 90,000 MWh/year
- Wind 30% → 60,000 MWh/year
- Hydro/biomass 15% → 30,000 MWh/year
- Natural gas backup 10% → 20,000 MWh/year
Capacity needed (using typical capacity factors):
- Solar CF = 0.20 → Capacity_MW = 90,000 MWh / (8760*0.20) ≈ 51.4 MW
- Wind CF = 0.35 → Capacity_MW ≈ 19.6 MW
- Hydro CF = 0.50 → Capacity_MW ≈ 6.9 MW
- Gas CF = 0.90 → Capacity_MW ≈ 2.5 MW
Cost & emissions (example LCOE and emission factors):
- LCOE: Solar $0.04/kWh, Wind $0.035/kWh, Hydro $0.06/kWh, Gas $0.07/kWh
- Emission factors: Renewables lifecycle 0.05 kg CO2/kWh, Gas 0.40 kg CO2/kWh
Annual cost:
- Solar: 90,000,000 kWh * $0.04 = $3.6 M
- Wind: 60,000,000 * $0.035 = $2.10 M
- Hydro: 30,000,000 * $0.06 = $1.80 M
- Gas: 20,000,000 * $0.07 = $1.40 M
Total annual electricity cost = $8.9 M
Annual CO2:
- Solar: 90,000,000 * 0.05 kg = 4,500,000 kg = 4,500 t
- Wind: 60,000,000 * 0.05 = 3,000 t
- Hydro: 30,000,000 * 0.05 = 1,500 t
- Gas: 20,000,000 * 0.40 = 8,000 t
Total CO2 ≈ 17,000 tonnes/year
Compare to previous mix (example): If town used 60% gas + 30% coal + 10% hydro before:
- Old emissions roughly 103,000 t CO2/year → switching to proposed reduces emissions by ~86,000 t (~83% reduction).
- Old annual cost at $0.06/kWh = 200,000,000 * 0.06 = $12.0 M → proposed cost $8.9 M → savings ~$3.1 M/year (depends on financing & capital costs).
Notes on realism:
- These are simplified (no capital recovery, financing, or storage costs). For a more realistic economic case include capital costs, annualized capital recovery (levelized capital cost), maintenance, incentives, and storage cost for dealing with intermittency.
- Storage: adding batteries to firm renewables will raise LCOE. Estimate battery CapEx and cycle life or use a local battery LCOE estimate (e.g., +$0.02–0.10/kWh depending on dispatch needs).
- Grid upgrades and permitting costs are also important and should be discussed qualitatively or quantitatively if data are available.
5) Defense prompts & sample answers students should prepare
- Why sustainable? Because the plan relies mostly on low-carbon, renewable sources that are renewable forever (solar/wind/hydro) and reduces lifecycle CO2 dramatically.
- How does it reduce environmental impact? Reduces CO2, air pollutants (SOx, NOx), water use (vs thermal plants), and health impacts. Lifecycle land/wildlife impacts should be mitigated with siting and design.
- Economic feasibility? Show LCOE comparison, expected annual operating cost and potential savings vs fossil baseline, plus job creation in installation/maintenance. Discuss capital cost and possible funding (grants, bonds, PPPs).
- Intermittency/backup? Explain role of gas as peaker/flex resource, storage options, demand-response and geographic diversity (wind/sun balancing).
- Social impacts & equity? Address displaced workers from fossil sector (retraining), community engagement for siting, programs to ensure low-income households benefit (subsidies, rooftop programs).
6) Rubric (suggested scoring out of 20)
- Clarity of plan & presentation (4 pts)
4 = Clear, concise plan and visuals; 3 = mostly clear; 2 = somewhat unclear; 1 = confusing.
- Use of scientific evidence & calculations (6 pts)
6 = Accurate calculations, correct use of capacity factors, LCOE, emissions factors; 4–5 = minor errors; 2–3 = incomplete; 0–1 = missing.
- Environmental analysis (4 pts)
4 = Quantitative CO2 reduction estimate + discussion of other impacts; 2 = qualitative only; 0–1 = missing.
- Economic analysis (4 pts)
4 = Annual cost + comparison to baseline + discussion of capital/financing; 2 = partial; 0–1 = missing.
- Social & feasibility considerations (2 pts)
2 = Addresses jobs, equity, permitting, and timeline; 1 = partial; 0 = missing.
7) Differentiation & extensions
- Struggling groups: Provide a teacher dataset (pre-computed capacity factors and LCOE); let them focus on interpreting results and defense.
- Advanced groups: Ask for capital cost annualization, grid stability modeling, hourly output profiles and storage sizing, lifecycle analysis of materials, or a carbon price sensitivity analysis.
- Cross-curricular: Economics (cost-benefit), civics (policy incentives), art (visual design, community outreach).
8) Common data sources students can use
- National/regional energy agencies for LCOE and capacity factors
- NREL (US), IEA, local utility reports for local resource assessments
- IPCC or EPA for emission factors (or national inventories)
- Peer-reviewed articles and industry reports for lifecycle emissions
9) Tips for teachers
- If local data are hard to find, give students a “local dataset” sheet to ensure comparability between groups.
- Emphasize the concept of capacity factor and why nameplate capacity ≠ annual output.
- Encourage students to show units in every calculation and to check reasonableness (order-of-magnitude checks).
- Allow students to present with posters, slides, or short videos (3–5 minutes).
If you’d like, I can:
- Produce a printable one-page student worksheet and a teacher answer key for the worked example.
- Create a Google Sheet template (with the formulas already in place) you can copy for students.
- Adapt the example numbers to your actual local data if you provide: annual demand, existing mix, and known local resources (average solar insolation, wind speeds, hydro capacity).
