Country produces 10 per cent of the world's
hydro-electricity
Canada produced about 66 per cent of its electricity from
renewable sources, according to a new report.
The country is the second biggest producer of hydro
electricity in the world, accounting for 10 per cent of the entire world’s
generation.
About 60 per cent of Canada’s electricity in 2015 was
produced by hydro with the remaining amount coming from wind, solar and
biomass, according to the National Energy Board (NEB) report.
Shelley Milutinovic, chief economist at the board, said:
“Canada’s hydro generation has allowed the country to be one of the global
leaders in renewable energy for years.
“Now, as solar, wind and other technologies become more cost
competitive, we expect to see a continuing increase in their adoption in the
future.”
Only five other countries in the world — Norway, New
Zealand, Brazil, Austria and Denmark — produce a similar or greater amount of
renewable electricity.
In its report, the NEB said: “About 60 per cent of Canadian
electricity came from hydro power in 2015, typically from large facilities with
reservoirs.
“This type of hydro power is a valuable part of Canada’s
generation mix, since it economically stores energy and moderates fluctuations
from more intermittent renewable sources.
“Run-of-river projects do not require reservoirs and are
less disruptive to water flows, but operate on a much smaller scale.”
It said wind power capacity had increased 20-fold between
2005 and 2015.
But it added: “The intermittency of wind generation is still
a challenge for widespread adoption. One way of overcoming this difficulty is
by trading electricity with neighboring jurisdictions to help moderate
generation fluctuations.
“This strategy allows Denmark to generate 50 per cent of its
electricity from wind sources.”
Biomass provided about two per cent of the country’s
electricity, while solar contributed just 0.5 per cent.
“Other renewable technologies, such as offshore wind, tidal
power, and geothermal energy, have not experienced significant uptake in
Canada, but still have potential,” the report said.
“Offshore wind projects are being proposed on Canada’s west
and east coasts, and a 20-megawatt tidal power facility already exists in Nova
Scotia.
“Large scale geothermal energy may be possible on Canada’s
west coast by harnessing the ‘Ring of Fire’ around the Pacific Ocean.
Geothermal projects are also being considered in isolated northern communities,
which would benefit from combined heat and power.”
The report said renewables were “becoming more cost
competitive” and their low carbon emissions “have also aligned them with
current policy priorities”.
“As a result, the increased adoption of renewables is
expected to continue in Canada and abroad,” the NEB added.
