Solar Energy

Technologies for Getting to Zero Emissions by 2060

Question: How fast are technologies to address climate change developing, particularly with regard to solar energy?

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 replace fossil fuels: solar, hydro, thermal, tidal, nuclear. One of the most promising is solar energy.

As a vast country, Canada has an abundance of potential for solar energy.

To answer the question on how fast solar energy technologies are developing, GenerallyEclectic looked at articles in Science Daily on solar energy for 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.
