Addressing frequent myths round renewable energy



The rise of wind and photo voltaic world wide is unprecedented. The Worldwide Power Company’s 2024 World Power Outlook described renewables increasing at file tempo, led by photo voltaic, and producing slightly below half of the world’s electrical energy in 2030, forward of energy from fossil fuels. On the identical time, demand for fossil fuels is projected to peak by the top of the last decade.

Canada’s hydropower-rich grid is 85% non-emitting with wind and photo voltaic presently making up 7% of the nation’s complete electrical energy era, nonetheless research point out that Canadian energy demand might double between now and 2050. In the meantime, the Canada Power Regulator tasks that the share of wind and photo voltaic would rise to between 33% and 37% of electrical energy era in a net-zero 2050. To fulfill this problem, the federal authorities has proposed the Clear Electrical energy Laws to assist be sure that Canada’s energy system stays each clear and reasonably priced within the years forward.

The next breaks down a number of the frequent misconceptions about using wind and photo voltaic in Canada and world wide.

Delusion: Renewables can contribute solely a small share of grid electrical energy as a result of they solely work when the wind blows and the solar shines.
Reality: There are various options out there to enhance wind and photo voltaic, which already make up greater than 60% of electrical energy era in some international locations.

  • It’s true that wind and photo voltaic are variable assets that present most energy to the grid when the solar shines or the wind blows. Nonetheless, options are out there to enhance these assets, from grid-scale storage to raised interconnections to demand-side measures.
  • A take a look at different international locations world wide gives loads of examples of present wind and photo voltaic shares which can be a lot larger than Canada’s immediately, together with Denmark (67% in 2023), round 40% in Germany and the Netherlands,  28% in Australia, and the U.Ok. (34%).
  • Wind and photo voltaic generated extra energy than fossil fuels within the EU within the first half of 2024, making up about 30% of the bloc’s complete era. 
  • South of the border, the U.S. had a share of 16% in 2022, though with nice state-level variation. Over a 3rd of all U.S. states (18) generated greater than 20% of electrical energy from wind and photo voltaic in that 12 months. The U.S. states with the very best shares had been Iowa (63%) and South Dakota (55%). Others with comparatively excessive shares embrace main states like California (34%) and Texas (26%).

Delusion: Renewables are costly, and the price of vitality storage required to assist renewables is prohibitive.
Reality: Renewables are among the many least expensive sorts of energy era out there and are value aggressive in Canada even with the prices of storage included.

  • A Clear Power Canada report, A Renewables Powerhouse, discovered that electrical energy from wind and photo voltaic is already cost-competitive with pure gasoline era in Ontario and Alberta (the 2 provinces studied), with much more value reductions on the horizon.
    • When Canada’s carbon worth is added to the equation, each wind and photo voltaic are considerably cheaper than pure gasoline already immediately.
    • Even when the prices of battery storage are included, each wind and photo voltaic are cost-competitive in lots of eventualities within the two provinces studied.

  • Analyses for the U.S. from Lazard and the Power Info Administration present related outcomes. Each discover wind and photo voltaic to be cost-competitive with pure gas-fired electrical energy within the U.S. even with no carbon worth. As well as, estimates present that wind and photo voltaic plus storage will be cost-competitive with natural-gas-fired electrical energy.

Delusion: Electrical energy from renewables shouldn’t be clear when you think about the assets required to provide photo voltaic panels and wind generators.
Reality: Wind and photo voltaic have a lot decrease life cycle emissions than fossil-fuel-fired era.

  • The greenhouse gasoline emissions of electrical energy era from renewables like wind and photo voltaic are significantly decrease than energy from pure gasoline and coal.
    • A U.S. Nationwide Renewable Power Laboratory assessment confirmed that complete life-cycle greenhouse gasoline emissions from photo voltaic, wind, and nuclear (from manufacture to disposal) are significantly decrease and fewer variable than these from pure gasoline and coal. Particularly, the median complete life-cycle emissions from pure gasoline energy is sort of 40 instances that of wind and greater than 10 instances that of photo voltaic. 

Delusion: Renewables usually are not clear once you account for the gear waste they generate at their finish of life.
Reality: Renewables generate considerably much less waste than fossil fuels.

  • Analysis that particularly checked out waste from photo voltaic panels reveals that 35 years of world projected cumulative photo voltaic panel waste is dwarfed by the waste generated by fossil gas vitality and different frequent waste streams.
    • For instance, if there was no transition to renewable vitality sources, coal ash and oily sludge waste generated from fossil gas vitality can be 300 to 800 instances and two to 5 instances bigger, respectively, than photo voltaic panel waste by 2050.
  • Though some 85% to 90% of the mass of a wind turbine and photo voltaic panel will be reused or recycled, most is presently directed to landfills or is being saved pending future recycling choices, in response to a 2021 report.
  • Quite a few coverage instruments can be found to attenuate waste era and encourage circularity of supplies from renewables gear. Certainly, some provinces, like B.C. and Alberta, have already begun advancing recycling efforts.
  • Analysts anticipate rising vitality prices, improved recycling expertise, and authorities regulation to extend recycling charges. In actual fact, the recycling marketplace for photo voltaic panels alone is projected to be price US$2.7 billion globally by 2030, up from solely US$170 million final 12 months.

Delusion: Renewables may fit elsewhere however usually are not suited to Canada
Reality: Canada has a number of the greatest renewable energy era potential on this planet

  • A 2021 research analyzed the power of photo voltaic and wind to satisfy electrical energy demand in over 40 international locations and ranked Canada second.
  • Earlier evaluation equally discovered vital potential for wind and photo voltaic throughout Canada. Highlights embrace on-shore wind potential in Newfoundland and Labrador and Saskatchewan, off-shore wind potential in B.C. and Ontario, and photo voltaic potential in Ontario and the Prairies.
  • Atlantic Canada is house to a number of the greatest wind energy assets on this planet, with a research stating that “offshore wind may very well be for Atlantic Canada what oil was to Texas or hydro energy to Quebec.” 
  • Based on the federal authorities, components of southern Alberta, Saskatchewan, and Manitoba have been proven to have excessive solar energy potential.
  • In actual fact, Canada’s hydro-dominated electrical energy community is well-suited to enhance the combination of great shares of wind and photo voltaic. Evaluation from 2022 discovered that Canada might see wind and photo voltaic attain a penetration fee of 54% throughout the nation on common, with even larger charges potential when including demand-side measures.
  • Moreover, Canada has “super potential for pumped-storage hydropower,” which might retailer energy generated from wind and photo voltaic, with greater than 8,000 GW recognized at nearly 1,200 websites, in accordance to WaterPower Canada.
