We have good reason to celebrate this year's solstice according to Al Gore.
“At the turn of the 21st century, some scoffed at projections that the world would be installing one gigawatt of new solar electricity per year by 2010. That goal was exceeded 17 times over; last year it was exceeded 39 times over; and this year the world is on pace to exceed that benchmark as much as 55 times over.”
Gore says such growth is comparable to the industry boom of cellphones, which were predicted to only claim about 900,000 subscribers by the year 2000 when first introduced in the early 1980s. When the 20th century came to an end, there were over 109 million subscribers. Now there are 6.8 billion. And we have solar-powered cellphones.
