I can do this — but I need to know your location (city / county / state / country) and whether you want results for the immediate city, a larger region (county/state/province), or the whole country. If you prefer, I can run a generic example (e.g., a typical US state) so you can see the method and sample numbers.
Below I give a clear step‑by‑step research plan, a data table template you can use, recommended data sources/tools, formulas to compute output and cost, and typical reference ranges you can expect for each technology. Once you tell me the location (or say “use example”), I will collect local figures and fill the table.
1) What I need from you
- Tell me the location and spatial scope (city / county / state / country).
- Confirm if you want utility-scale only, rooftop/behind‑the‑meter included, or both.
- Any other constraints (budget, focus on CO₂ only, include lifecycle impacts, include air pollutants?)
2) Step‑by‑step research plan I will follow
- Identify main available energy sources in the area (solar, wind, hydro, natural gas, coal, oil, biomass, geothermal, nuclear, imports).
- For each source gather:
- Installed capacity (MW) and potential resource (e.g., GW potential or kWh/yr)
- Typical/observed annual output (MWh/yr) and capacity factor
- Cost metrics (current retail/wholesale price if available, and LCOE or levelized cost estimates) — expressed as $/kWh
- Environmental impact: CO₂ emissions (gCO₂/kWh or tCO₂/yr), key air pollutants (NOx, SOx, PM), and major lifecycle notes
- Reliability: capacity factor, dispatchability, seasonal/diurnal variability, grid connection constraints
- Cross‑check data from at least two authoritative sources and note data year.
3) Recommended data sources and tools
- National/regional grid operator or energy authority (e.g., EIA for US, Ofgem/BEIS for UK, ENTSO‑E for EU countries) — installed capacity and generation by fuel.
- NREL/PNNL (US) and PVWatts for local solar output estimates (or Global Solar Atlas).
- Global Wind Atlas for wind speed and wind power density.
- Hydro potential: national water resources agencies, International Hydropower Association.
- Plant‑level emissions and generation: EPA eGRID (US) or national emission inventories.
- Cost and LCOE references: Lazard LCOE reports, IEA, NREL ATB.
- Lifecycle CO₂ ranges: IPCC and IEA lifecycle analyses.
- Local utility tariffs / wholesale market prices from the regional market operator.
4) Data table template (use this to collect/return results)
Columns:
- Energy source
- Local resource/potential (e.g., MW installable or kWh/yr)
- Installed capacity (MW)
- Typical capacity factor (%) or annual output (MWh/yr)
- Output potential (MWh/yr) — computed
- Cost per kWh (retail/wholesale and LCOE) ($/kWh)
- CO₂ emissions (gCO₂/kWh or tCO₂/yr)
- Other environmental/pollution notes
- Reliability & availability (dispatchable? hourly/seasonal limits)
- Data sources & year
5) Key formulas and how I’ll compute values
- Annual generation (MWh/yr) = Installed capacity (MW) × Capacity factor × 8,760 hr/yr
- LCOE (if needed) can be estimated from reference LCOE tables (I can compute from capital cost, O&M, fuel, discount rate and capacity factor if you want a custom calculation)
- CO₂ emissions (tCO₂/yr) = Annual generation (MWh/yr) × emissions (tCO₂/MWh)
6) Typical reference ranges and quick fact sheet (global / common ranges)
Note: these are typical ranges — local values may differ.
Solar PV (utility-scale)
- Capacity factor: ~15–30% (higher in sunny deserts; lower in cloudy regions)
- LCOE (utility-scale): ~$0.03–0.06 /kWh (3–6¢/kWh) in favorable markets; rooftop higher (~$0.08–0.20/kWh)
- Lifecycle CO₂: ~20–80 gCO₂/kWh (IPCC/IEA ranges)
- Reliability: non‑dispatchable, diurnal; needs storage or backup for night/clouds
Onshore wind
- Capacity factor: ~25–45% (site dependent)
- LCOE: ~$0.02–0.06 /kWh (2–6¢/kWh) in good sites
- Lifecycle CO₂: ~3–24 gCO₂/kWh
- Reliability: variable, seasonal; complementary to solar in some climates
Offshore wind
- Capacity factor: ~40–60%
- LCOE: ~$0.06–0.18 /kWh (higher capital cost)
- Lifecycle CO₂: similar to onshore but a bit higher per kWh during construction
Hydropower (large)
- Capacity factor: highly variable (20–60%+ depending on reservoir)
- LCOE: ~$0.03–0.08 /kWh (site dependent)
- Lifecycle CO₂: ~4–140 gCO₂/kWh (low for run‑of‑river, higher for some reservoirs due to methane)
- Reliability: dispatchable if reservoir storage; seasonal flow dependence
Natural gas (combined cycle)
- Capacity factor: ~40–80% (dispatchable)
- Short‑run marginal cost: depends on local gas price; typical wholesale ~$0.03–0.08 /kWh (fuel & plant operation)
- LCOE (including capital): ~$0.04–0.07 /kWh (varies by region and fuel)
- Direct CO₂ emissions (combustion): ~350–550 gCO₂/kWh (combustion only); lifecycle ~400–600 gCO₂/kWh
Coal (if present)
- Capacity factor: ~50–80%
- LCOE: ~$0.06–0.15 /kWh (regionally variable)
- CO₂ emissions: ~800–1,100 gCO₂/kWh (combustion), lifecycle similar
- Other pollution: high SOx, NOx, PM unless controls are installed
Oil / Diesel
- Typically high cost for electricity (~$0.15–0.50 /kWh) and high emissions per kWh (similar or worse than coal), usually used as peaking/backups
Biomass/biogas
- Capacity factor: variable, often high if run‑of‑plant
- LCOE: site specific ~$0.06–0.15 /kWh
- CO₂: complex (biogenic CO₂ often treated differently); lifecycle depends on feedstock and land use
Nuclear
- Capacity factor: ~80–95%
- LCOE: ~$0.08–0.12 /kWh (very site and financing sensitive)
- Lifecycle CO₂: ~3–12 gCO₂/kWh
- Reliability: dispatchable baseload, long lead times/capex
7) Example row (illustrative, not location‑specific)
- Solar PV — Resource: good insolation (5 kWh/m²/day) — Installed: 100 MW — Cap. factor 20% — Annual output ~175,200 MWh/yr — LCOE ~$0.04/kWh — CO₂ ~40 gCO₂/kWh — Non‑dispatchable; needs storage/curtailment considerations — Source: PVWatts, Lazard.
8) How I will present findings
- A filled table for each major source with numbers and source citations
- Short summary comparing cost, emissions, and reliability
- Actionable notes: e.g., “if your goal is lowest CO₂/kWh, prioritize wind + solar + storage; if reliability matters most, keep gas or hydro dispatchable capacity.”
- If you want, a chart (supply stack) and simple scenario (e.g., replace X MW of gas with Y MW of wind + Z MWh storage) with CO₂ and cost implications.
Next step
- Tell me the location and scope. I’ll collect local data from authoritative sources, fill the table, and give a concise summary.
If you want now, I can also run a ready example for a “typical US state” so you can see the final output format before I fetch local data for your exact area. Which do you prefer?
