Overview on Renewable Energy
Sector is growing due to the favourable economics of wind and solar, security concerns around oil and gas (wars), and tracking emissions goals
Canada's grid (largely hydropower) is 84% non-emitting
Wind and solar make up 7% of Canada's electricity generation, could rise to 30-33% in a net-zero 2050
Clean electricity regulations will help ensure Canada's renewable energy remains cheap and affordable
Myth 1 - Wind and Solar Contribute Little to Grid, Only Functional when Wind Blows and Sun Shines
Stronger grids and interconnective systems are being developed to meet high energy demand (e.g., smart charging of EVs, industrial demand), affordable storage, and dispatchable power supply
Denmark, EU, and 1/3 of US states making substantial progress in transitioning to wind/solar
Recognized renewables penetration rate of 54% in Canada
Myth 2 - Renewables are Too Expensive, Cost of Energy Storage is Prohibitive
Solar and wind already cost-competitive with natural gas with prices continuing to decline, esp considering LCOE
As costs decrease, infrastructure like storage and increased transmission capacity can be improved upon
80% decline in lithium-ion battery prices over the last ten years, could halve during this decade
Some southern Alberta municipalities receive substantial tax revenue from solar/wind
Myth 3 - The Materials Needed for Solar Panels and Wind Turbines make Renewable Energy Unclean
Studies show that GHGs from renewables (including the manufacturing process) are substantially lower than that of coal and natural gas
Resource extraction + power plant construction + operation + decommissioning + recycling/disposal = renewables emitting less GHG with less variable results
Median GHG life cycle from natural gas is 40x more than wind, 10x more than solar
Myth 4 - Renewables Aren't Clean Because of Equipment Waste
35 years of projected waste from solar panels is still substantially less than that of fossil fuels and other common waste systems
If there was no transition, coal ash and oily sludge waste generated from fossil fuels would be 300-800x larger than that of solar panel waste by 2050
85-90% of mass turbines and panels can be recycled, although most is currently being sent to landfill
Policy tools such as end-of-life regulations, extended producer responsibility, eco-design regulations, labelling and certification, and measurable recovery and recycling targets should be implemented
Rising energy costs, improved recycling technology, and government regulation = improvement in recycling rates
Myth 5 - Renewables are not Ready to be Put Into the World
Solar and wind are well established and readily available
Renewable sources set to contribute 80% of new power capacity worldwide by 2030, solar making up half
Solar global installed capacity to surpass coal by 2027, global spending on solar set to be higher than oil by $10 million in 2030 for net-zero by 2050
On-shore (turbines on land) wind proven, mature technology with an extensive global supply chain
Off-shore (turbines in water) wind to follow, takes advantage of stronger winds at sea
Myth 6 - Renewables Won't Suit Canada Specifically
Canada ranked 2nd for ability to use solar in wind to meet electricity demand
Provincial potential, on-shore wind in Newfoundland and Labrador and Saskatchewan, off-shore wind in BC and Ontario, solar in Ontario and the Prairies
Offshore wind can dominate in Atlantic Canada as much as oil in Texas
Alberta, Saskatchewan, and Manitoba with large solar potential
