加拿大智库Fraser Institute发布报告称，加拿大政府计划在2050年前实现电力需求完全由低碳或零碳能源供应的目标“几乎不可能”。为了实现联邦政府的净零排放目标，加拿大要求各省实现电力生产完全脱碳。政府预计到本世纪中叶，需要额外684TWh的发电能力。然而，Fraser Institute的研究表明，如果完全依靠太阳能、风能、水力或核能来满足这一需求，将面临巨大的建设规模和时间挑战，需要大量的土地和漫长的建设周期。

☀️如果加拿大完全依靠太阳能发电来满足2050年的电力需求，则需要建造840个艾伯塔省Travers Solar规模的太阳能发电站，每个项目需要大约2年的建设时间，总计需要1680年的建设时间，并将占用907,000公顷的土地。

💨如果完全依靠风力发电，则需要建造575个现有365兆瓦项目的规模的风力发电设施，每个项目需要2年的建设时间，总计需要1150年的建设时间。

💧如果完全依靠水力发电，加拿大需要建造134个不列颠哥伦比亚省C站规模的设施，每个设施的容量为1100兆瓦，所有这些项目上线将需要大约938个建设年或每个项目7年。

☢️如果完全依靠核能来满足加拿大未来的电力需求，则需要建造16个安大略省布鲁斯核电站规模的核电站，该核电站的装机容量为6232兆瓦。每个设施平均需要7年/项目或112个建设年。

Canada government’s plans to meet the country’s future electricity demand with low or no carbon sources is ‘likely impossible’ within the broader net-zero GHG mitigation plan of 2050, claims a new report by public policy think tank Fraser Institute.  The country’s Clean Electricity Regulations (Canada 2024a) requires all provinces to fully decarbonize their electricity generation to help meet the federal government’s 2050 net-zero target. According to government estimates, it will require an additional 684 TWh of generation capacity by mid-century.  In its study titled Decarbonizing Canada’s Electricity Generation: Rapid Decarbonization of Electricity and Future Supply Constraints, Fraser Institute assesses what it would entail meeting all of this electricity demand till 2050 with each individual clean energy source.  If Canada sought to meet 100% of the expected demand with solar power generation, it would require to construct 840 solar power generation stations the size of Alberta’s Travers Solar. The latter covers close to 3,330 acres of land with 692 MW DC/ capacity. Each of these 840 projects will require an estimated 2-year construction timeline, taking the total timeline to 1,680 construction years. These projects will also take up 907,000 hectares of land, which is equal to around 1,440 times the land area of Toronto, according to the study. Similarly, meeting the 2050 target with only 100% wind power generation will require 575 installations the size of a 365 MW existing project, each requiring 2 years to build, adding up to 1,150 construction years.  Hydropower is another source the report considers. Canada will need to build 134 such facilities the size of Site C power station in British Columbia with 1,100 MW capacity each. Bringing all of these projects online will require some 938 construction years or 7 years/project. Meeting all of Canada’s future electricity needs with nuclear power alone will necessitate the construction of 16 additional plants the size of Ontario’s Bruce Nuclear Generating Station which is 6,232 MW installed capacity. With each facility requiring an average of 7 years/project or 112 construction years.
