Most myths about renewable energy come from outdated information, from early technology that has since improved, or from real trade-offs that get exaggerated. Solar works in Canadian winters, cold-climate heat pumps heat homes well below freezing, and wind and solar are now among the cheapest sources of new electricity in many places. Here are 12 common myths and what the evidence actually shows.
Key takeaways
- Canada's climate is not a barrier: solar panels work well in cold, sunny weather, and modern heat pumps are built for Canadian winters.
- Renewables have become cost-competitive, though costs depend on location and project.
- Grids can stay reliable with more wind and solar by using hydro, storage, interties and good planning.
- Environmental impacts like wildlife effects and recycling are real but manageable, and generally smaller than those of fossil fuels.
Myths about Canada's climate
Myth 1: "Solar doesn't work in Canada."
Solar panels respond to light, not heat, and they actually run more efficiently in cool temperatures. Many Canadian cities get as much or more annual sunshine than parts of Germany, which built a large solar industry. Production dips in December and January, and snow can cover panels temporarily, but annual output in the Prairies and southern Ontario is solid. Our solar page explains seasonal production.
Myth 2: "Heat pumps stop working when it gets really cold."
Older heat pumps struggled in deep cold, but modern cold-climate models keep producing useful heat well below -25°C, and some are rated to around -30°C. In the coldest regions, many homes pair a heat pump with backup heat for extreme days. Correct sizing and installation matter more than anything.
Myth 3: "Wind turbines freeze up in winter."
Canadian winters are windy, and turbines here are designed for cold, with heated blades or ice-detection systems on many models. Winter is often the most productive season for wind. Learn more on our wind page.
Myths about cost
Myth 4: "Renewables are too expensive."
The cost of wind and solar has fallen dramatically over the past 15 years. In many markets, new onshore wind and utility-scale solar are among the lowest-cost sources of new electricity. Costs still vary by location, financing and grid connection, and adding storage raises the price, but "too expensive" is no longer accurate as a general rule.
Myth 5: "Home solar never pays for itself."
Payback depends on your province's electricity prices, your roof, local incentives and how you're credited for exported power. In many Canadian situations, the payback period is meaningfully shorter than the 25-plus-year life of the panels. In others, especially provinces with very low hydro rates, it can be long.

Myth 6: "Only wealthy people can afford clean energy."
Upfront costs can be high, but loans, on-bill financing, rentals and community solar make clean energy more accessible, and efficiency upgrades like air sealing are relatively inexpensive. Our financing page compares options.
Myths about reliability
Myth 7: "The grid will collapse if we add more wind and solar."
Grids already integrate large amounts of variable renewable energy by forecasting weather, using flexible sources like hydro and batteries, and trading with neighbours. More renewables do require planning and investment, but they don't make reliable grids impossible. Canada has a major advantage: abundant hydro reservoirs that can balance variable output.
Myth 8: "Renewables can't provide power when the sun isn't shining or the wind isn't blowing."
No single renewable source runs all the time, which is why grids combine them. Hydro, geothermal, bioenergy and nuclear can run steadily; batteries cover hours; and wind and solar often complement each other seasonally. A diverse mix is the answer.
Myths about the environment
Myth 9: "Wind turbines kill huge numbers of birds."
Wind turbines do kill some birds and bats, and careful siting matters. But studies consistently find that collisions with buildings and windows, and predation by domestic cats, kill far more birds each year. Climate change itself is one of the biggest long-term threats to bird populations.
Myth 10: "Solar panels and batteries can't be recycled."
Solar panels are made largely of glass, aluminum and silicon, all of which can be recovered. Lithium-ion batteries contain valuable metals that recyclers are increasingly reclaiming. Recycling systems are still scaling up in Canada, and most panels and EV batteries in service today won't need replacing for many years.
Myth 11: "Making solar panels or EVs creates more emissions than they save."
Manufacturing does create emissions, but a solar panel typically "pays back" the energy used to make it within a few years and then produces clean power for decades. EVs start with a larger manufacturing footprint than gasoline cars, mostly from the battery, but on Canada's relatively clean grids, they generally make that up within the first couple of years of driving. See our electric vehicles page.
Myth 12: "Canada's emissions are too small to matter."
Canada produces a small share of global emissions, but its per-person emissions are among the highest in the world. Countries with smaller shares together make up a large portion of the global total, so every country's action counts. Clean energy also brings local benefits, from cleaner air to new jobs.
Frequently asked questions
What's the most common renewable energy myth in Canada?
The belief that renewables don't work in cold climates is probably the most widespread. In reality, solar panels perform well in cold weather, wind is strongest in winter, and modern cold-climate heat pumps are designed for Canadian conditions.
Do I need batteries if I install solar panels?
Not usually. Most Canadian homes with solar stay connected to the grid, which acts as backup. Batteries add backup power during outages and can help on certain rate plans, but they increase cost.
Is renewable energy better for the environment than fossil fuels overall?
Across their full life cycle, wind, solar, hydro and other renewables typically produce far lower greenhouse gas emissions and air pollution than coal or natural gas. Every energy source has some impacts, which is why siting, recycling and responsible mining matter.
The bottom line
Renewable energy isn't perfect, and honest trade-offs deserve attention. But many of the most common objections are based on outdated technology or exaggeration. For Canadian homeowners, the practical reality is that solar, wind, heat pumps and EVs work in our climate and are becoming more affordable, and understanding the facts is the first step to making good decisions for your home.
