Saturday, June 21 is worldwide Solar Day.
In honor of this event, here are some fun facts about solar energy technology:
Estadio Nacional World Cup Stadium has more solar power capacity than 11 competing countries.
Here is the total area of solar panels it would take to power the world, Europe, and Germany:
Global solar PV demand will pass 150 GW by the middle of this year:
US solar installations in 2014 are expected to double 2012 solar installations:
Solar now costs less than coal and natural gas as an energy alternative for the U.S., even if you don't count the health and environmental costs of burning fossil fuels!
This amazing drop in cost is just the latest in a long trend for solar:
What This Means for Solar Energy Technology
If you think this paints a rosy picture for solar's future as a practical, safe, clean, renewable energy technology, there are lots of experts who support that conclusion. If you want the details, including possible pitfalls, here is an excellent and thorough article by the Institute for Local Self-Reliance: The Future of Solar Economics and Policy.
I hate to end this article on a "downer," but there is a downside to all this good news. According to the International Renewable Energy Agency (IRENA), if solar energy deployment doesn't increase 12 times over by the year 2030, the world is headed towards a "climate catastrophe." The sooner we progress beyond our fossil foolishness, the better for all of us.
Is this realistic, or even possible? In the words of the IEA, "Transitioning towards renewable energy is possible at negligible additional cost. The economic case for the renewable energy transition is even stronger when we include socio-economic benefits — with these factors are taken into account, switching to renewable energy results in savings of up to $740 billion per year by 2030."
