The Electrical Grid
Technologies for Getting to Zero Emissions by 2060
Question: How fast are technologies to address climate change developing, particularly with regard to the electrical grid?
GenerallyEclectic looked at Canada's Greenhouse Gas emissions and found that in 2012, the combustion of fossil fuels (petroleum products, natural gas, coal) account for just under 80 percent of emissions. In a low emission world, this energy source will need to be replaced. There are a number of candidates to produce the energy to replace fossil fuels: solar, hydro, thermal, tidal, nuclear and wind.
Once produced, this energy will need to be distributed. When GenerallyElectic looked at how to Canada will get emissions to zero by 2060, it concluded that the electrical system will need to grow by about 3.76 times. Clearly, the creation of a large, reliable, efficient electrical grid will be important to a zero emission future.
The vastness of Canada provides a unique set of complexities for the development of an electrical grid.
To answer the question on how fast electrical grid technologies were developing, GenerallyEclectic looked at articles in Science Daily on the electrical gridfor the previous eighteen months, which at the time of writing was December 1, 2018 to May 31, 2020. Titles, summaries and links to the relevant articles are provided, so you can make your own judgments.
The summaries presented here are limited to Science Daily findings, which are in turn determined by Science Daily's methodology, which is outlined at About Science Daily. To the extent that Science Daily undoubtedly missed some technological developments, this summary under-reports developments.
