In 2001 I worked on a photovoltaic installation proposal for a ranch here in the Roaring Fork Valley that extracted hydrogen from water via the electricity from the PV panels, which would then power the homes and their cars. The PV panels were supported on steel cables that spanned a small canyon on the ranch. At $4M it was horrendously expensive, but it would have been the 1st residential use of this technology in the world.
The client decided to buy a Norman Rockwell painting instead.
We need to make sure that the people who are in charge of all the money in our world see PV as profitable. One way is to make drilling and mining less profitable (obviously), and by investing in alternative energy production technologies. We need national and local governments that are dedicated to these practices, that incentivizes and subsidizes the green technologies, at the expense of the extractive industries. Here in Pitkin County when you construct a building you are required to offset your energy consumption by either providing on site PV or by buying energy credits that invest in PV energy production elsewhere. You get credits for efficient building techniques, using sustainable building materials and practices.
We installed a 6KW PV system on our home in 2006, it cost a shit load of money, and it will never pay for itself, at least in my lifetime. But we have a $6 a month electricity bill for 4 months out of the year, and they look cool on our roof.
I don't think it is a given that ANWR will be developed. We need to change our way of living, either voluntarily now or by necessity in the not too distant future.
And BTW, the guy I worked for in 2001 patented the cable design and is now covering parking lots in the US, and starting to cover huge canals in India (with heavy governmental subsidies), thereby reducing evaporation while making electricity.
