Energy density — or more precisely, spatial power density — measures how much usable electricity a power source produces per unit of land it occupies. It is typically expressed in watts per square metre (W/m²) or megawatts per hectare (MW/ha).
This metric matters because land is finite, ecosystems are fragile, and every hectare converted to energy infrastructure is a hectare lost to forests, agriculture, wildlife, recreation, or watershed protection.
A 2022 study published in Scientific Reports (Nøland et al., 2022) compiled data from thousands of power plants worldwide. Their findings:
Typical solar PV spatial power density (nameplate)
Hydroelectric actual output density (varies by facility)
Key takeaway: When you account for the fact that solar panels only produce power during daylight and at reduced output on cloudy days, their effective energy density drops to as low as 1–3 W/m² — meaning solar requires 5× to 50× more land than hydroelectric power to deliver the same amount of energy over a year.
BC's electricity grid is already one of the cleanest in the world — over 95% hydroelectric. Here's what the numbers show when you compare solar to what BC already has.
Now fully operational (2025)
208 MWAC, two phases proposed
To match Site C's annual output of ~5,100 GWh with solar at BC latitudes, you would need approximately 15–19 projects the size of the Logan Lake proposal — consuming roughly 12,000–15,000 hectares of land. That's the size of a small city.
Capacity factor is the ratio of actual energy produced over a period to the maximum possible output if the plant ran at full nameplate capacity 24/7. It is the single most important metric for understanding real-world performance.
Solar developers market projects using nameplate capacity (peak watts under ideal conditions). But no solar panel operates at peak capacity for more than a few hours per day, and for zero hours at night. In northern latitudes like BC, winter days are short, sun angles are low, and snow/cloud cover further reduces output.
According to Lawrence Berkeley National Laboratory's tracking of U.S. utility-scale PV, even in sun-rich states like Arizona and California, median capacity factors range from 22–28%. At BC's latitude (~50°N), with shorter winter days, lower sun angles, snow, and cloud cover, 15–18% is a realistic estimate — and may be generous. (LBNL Data)
BC's peak electricity demand occurs on cold winter evenings — typically between 4:00 PM and 9:00 PM from November through February — when heating loads are highest. By this time of day in a BC winter, solar output is already at or near zero.
This creates a fundamental mismatch: the grid needs the most power precisely when solar panels produce the least (or nothing at all).
Without massive battery storage (which adds cost, land use, and its own waste stream), solar energy in BC is structurally mismatched with demand. The grid still needs dispatchable backup for every MW of solar added.

Total area required per megawatt of nameplate capacity, including panel arrays, roads, substations, setbacks, and fencing.
Bolinger & Bolinger, 2022 (IEEE/DOE)The Logan Lake proposal's project area — equivalent to roughly 1,450 football fields. All of it cleared, graded, fenced, and inaccessible for 25–30 years.
A 2025 study in Communications Earth & Environment (Hu et al., 2025) developed a consistent framework for measuring solar land transformation across the western United States. They found that direct land-use intensity ranged from 2.5 to 5.5 hectares per MW, with additional indirect impacts from access infrastructure, transmission corridors, and buffer zones.
Virginia's Department of Energy conducted a comprehensive re-evaluation in 2024 (Virginia DOE, 2024) and found that utility-scale solar development was consuming agricultural and forested land at rates that raised long-term food security and ecosystem concerns.
Post-wildfire recovery halted for 25–30 years
Corridors fragmented by fencing and infrastructure
Graded and compacted under panel arrays
Natural filtration and drainage patterns disrupted
Trails and public land locked behind security fencing
Revenue and management capacity reduced
For context: Our World in Data's comprehensive analysis shows that solar requires roughly 10× more land per unit of energy than nuclear, and 2–5× more than hydroelectric power. At BC latitudes with lower capacity factors, these ratios are even worse. Our World in Data
Applying the data above to the specific Logan Lake proposal:
| Metric | Marketing Claim | Real-World Reality |
|---|---|---|
| Capacity | "208 MWAC" | ~31–37 MW average output |
| Homes powered | "Tens of thousands" | Only during sunny hours; zero at night and near-zero in winter peak |
| Land commitment | "Minimal impact" | 776 ha cleared, fenced, inaccessible for ~30 years |
| Operating period | "Clean energy for decades" | 25–30 years, then full decommissioning required |
| End of life | "Fully recyclable" | No full-scale PV recycling exists in BC/Canada |
| Grid need | "BC needs more power" | BC's grid is 95%+ hydro; peak demand is winter evenings when solar produces nothing |
To produce the same annual energy as Site C (~5,100 GWh), BC would need to build approximately 15–19 Logan Lake–sized solar projects, consuming 12,000–15,000 hectares of land — and still require backup generation for every night and cloudy day. Site C does it on one site, runs 24/7, and lasts a century.
A July 2025 study in the Proceedings of the National Academy of Sciences(Xia et al., PNAS 2025) warned that the "looming challenge" of solar PV panel recycling is growing faster than solutions. Key findings:
A 208 MWAC facility would contain an estimated 400,000–600,000 solar panels, each weighing approximately 20–25 kg. That's roughly 8,000–15,000 tonnes of panel material alone — not including inverters, racking, wiring, transformers, and substation equipment.
At end of life (~2055–2060), all of this material must be removed. Canada currently has no dedicated solar panel recycling facility. The U.S. International Trade Commission noted in a 2024 briefing that PV recycling infrastructure remains "nascent" across North America. USITC, 2024
A 2026 study in Nature Communications (Nature, 2026) documented how degraded solar modules are increasingly exported from wealthy nations to developing countries with limited regulatory oversight and recycling capacity. This creates environmental justice concerns — wealthy nations benefit from "clean" energy while exporting the waste burden.
The recycling myth: While solar panels are technically recyclable, the economics don't work at scale. Recovering high-purity silicon from laminated panels costs more than producing new silicon. Until that changes, "recyclable" remains theoretical for the vast majority of panels reaching end of life. Solar Energy, 2024 · Warwick University, 2025
Solar panels degrade over time. Industry-standard warranties guarantee no more than 0.5–0.7% annual degradation, meaning a panel produces 12–20% less power at year 25 than when new. In harsh climates with extreme temperature swings, snow loading, and UV exposure — all present in BC's interior — degradation may be faster.
Output at rated capacity
Already below nameplate claims
Approaching end of useful life
Compare this to hydroelectric: BC Hydro's existing dams — some built in the 1960s — continue to operate at full capacity after 60+ years. With proper maintenance, hydroelectric facilities last 100+ years. Site C is designed for the same.
In the time one dam operates, a solar farm of equivalent output would need to be built, decommissioned, and rebuilt 3–4 times — each cycle consuming new materials, generating new waste, and re-disturbing the land.

Go to Official Engagement PageThe energy density problem isn't unique to BC — it's a fundamental characteristic of solar technology. A 2025 study comparing environmental impacts of solar and hydroelectric systems using real-case data from Turkey found significant differences. (Scientific Reports, 2025)
| Metric | Solar PV | Hydroelectric |
|---|---|---|
| Typical Capacity Factor | 10–25% | 40–60% |
| Energy Density (W/m², actual) | 1–3 | 5–50 |
| Land per GWh/year (ha) | 2–5 | 0.5–2 |
| Typical Lifespan | 25–30 years | 80–100+ years |
| Dispatchable? | No | Yes |
| Night-time Output | Zero | Full capacity |
| End-of-Life Waste | Millions of tonnes (panels, inverters, wiring) | Minimal (concrete & steel in place) |
A Norwegian study on land efficiency of renewable energy (Nøland et al., 2022) found that large reservoir-based hydropower achieved energy densities of 10–50 W/m², while solar PV in the same analysis ranged from 1–5 W/m² — a difference of up to 50×.
This gap becomes even more extreme at higher latitudes. BC sits at roughly the same latitude as London, England — solar irradiance is significantly lower than the equatorial regions where solar makes the most physical sense.
Solar energy has a role — in sun-rich regions, on rooftops, in deserts, and as distributed generation. But converting forest land in a northern, hydro-rich province to build industrial-scale solar is an objectively poor use of land, money, and natural resources. The data is clear: BC already has a better solution.
BC is in a unique position globally: its electricity grid is already over 95% renewable, powered by one of the world's finest hydroelectric systems. The question isn't whether BC needs clean energy — it already has it. The question is whether converting hundreds of hectares of recovering forest to intermittent, low-density solar generation makes sense when:
BC's peak demand is winter evenings. Solar contributes nothing during this critical period.
Adding solar doesn't displace fossil fuels in BC — there are almost none on the grid to displace.
Regenerating forest, watershed protection, wildlife habitat, recreation, and community forestry all deliver more community value.
Canada has no PV recycling infrastructure. Panels installed today become someone else's problem in 25 years.
