Today, I spotted this poster on Facebook:
The artist is Al Haug, who has published the poster on a Facebook page here. He is not selling the poster, but does indicate that those who post it should attribute this work to Al, and further states:
I can accept gifts to support my artwork thru paypal:
Use firstname.lastname@example.org as account. Send as a “gift” only. But you don’t have to send anything. And don’t be a poophead and try to sell this image- your karma would suffer greatly.
The cost of solar power is collapsing to the point that its use is about to explode across the United States, according to Kees Van Der Leun at Grist:
[T]he fact that 30 pounds of silicon, an amount that costs $700 to produce, is enough to generate a lifetime of household electricity baffled me. Over 25 years, the family would pay at least $25,000 for the same 100,000 kilowatt-hours (kWh) of electricity from fossil fuels — and its generation cost alone would total over $6,000!
Paul Krugman weighs in too, criticizing those who just can’t stop touting dirty coal and natural gas derived from tracking. Then he turns to the quickly falling cost savings of PV solar:
[P]rogress in solar panels has been so dramatic and sustained that, as a blog post at Scientific American put it, “there’s now frequent talk of a ‘Moore’s law’ in solar energy,” with prices adjusted for inflation falling around 7 percent a year.
Even more falling cost data at CNET.
