Renewables Overtake Coal As World's Largest Source of Power Capacity (ft.com)

The world's largest source of power capacity is now renewables, as roughly half a million solar panels were installed every single day last year. In addition, two wind turbines were erected every hour in countries such as China, according to the International Energy Agency. Financial Times reports (Editor's note: may be paywalled; alternate source): Although coal and other fossil fuels remain the largest source of electricity generation, many conventional power utilities and energy groups have been confounded by the speed at which renewables have grown and the rapid drop in costs for the technologies. Average global generation costs for new onshore wind farms fell by an estimated 30 percent between 2010 and 2015 while those for big solar panel plants fell by an even steeper two-thirds, an IEA report published on Tuesday showed. The Paris-based agency thinks costs are likely to fall even further over the next five years, by 15 percent on average for wind and by a quarter for solar power. It said an unprecedented 153 gigawatts of green electricity was installed last year, mostly wind and solar projects, which has more than the total power capacity in Canada. It was also more than the amount of conventional fossil fuel or nuclear power added in 2015, leading renewables to surpass coal's cumulative share of global power capacity -- though not electricity generation. A power plant's capacity is the maximum amount of electricity it can potentially produce. The amount of energy a plant actually generates varies according to how long it produces power over a period of time. Coal power plants supplied close to 39 percent of the world's power in 2015, while renewables, including old hydropower dams, accounted for 23 percent, IEA data show. But the agency expects renewables' share of power generation to rise to 28 percent by 2021, when it predicts they will supply the equivalent of all the electricity generated today in the U.S. and E.U. combined.

While the NA grid is somewhat interconnected, there are still separate network grids in case of catastrophic failure. On top of that, there isn't a big nationwide high voltage DC grid for the delivery of power from plants. And HVDC is the only way you're going to be transporting power that far while reducing the loss. AC it actually becomes very cost prohibitive very quickly over very long distances and more electricity is lost due to resistance and heat.

      Ontario's best solution for electricity has always been nuclear, followed by hydro-electric to round it out. Followed by coal and natural gas for peak demands. The current government(Liberal) decided that "coal is nasty, evil and dirty" and shut them down, instead of say retrofitting them. And there were even a few leaked documents that they wanted to do the same with natural gas power plants and wanted to ban natural gas for home use, forcing everyone onto electric. The price started climbing quickly once these cheap sources were removed from the grid.

The problem in Alberta is, whole lotta area and people are very spread out. Coal is plentiful, and in turn small out of the nowhere places where it's cost prohibitive to build NG, impossible to build nuclear, and where solar or wind is also prohibitive. They're now scrambling to build thousands of KM of power lines. Small towns and cities like Grande Prairie and Grande Cache rely on small scale coal plants to keep people from freezing to death in the winter when there are grid failures for example. The winter I spent in Grande Cache, the nighttime lows hit -48C with a windchill of -55C. The daytime highs were between -25C and -38C not counting windchills.
