Global Solar Council Launched at COP 21

The GSC strives to convey 3 Key Messages about solar power:

  • Solar power is already one of the cheapest forms of electricity globally and prices continue to decline fast. The levelised cost of solar electricity is 80% lower than it was during COP-15 in 2009. Solar provides a cost-effective means of fighting climate change today.
  • Solar power is the most versatile form of electricity generation and can be deployed anywhere in the world for the people of developing and developed countries alike. Solar also has the highest share of popular support of any electricity technology.
  • To avoid a greater than 2 ºC increase in global temperatures, it is imperative to strongly accelerate the deployment of solar power. A 10% share of global power generation by 2030, from less than 1% today, is possible given the right market conditions…

The Northern Hemisphere's procession of dwindling days is about to reach its nadir. The winter solstice is the year's shortest day, but the start of winter also launches the sun's steady climb towards the long, warm days of summer. 

The solstice occurs on Tuesday, December 22 at 4:48 UTC—that's late Monday night across most of North America. It happens at the same moment no matter where you live, but because we've divided Earth into 24 times zones people around the world observe it at 24 different times of day.

Why does the solstice occur anyway, and how have people observed it through history?
