    Or 41.5km^2 per TWh, much better than wind power, but would still need to blanket half the country's land mass to produce the amount of energy they consume. Though their it's not a complete dead end like wind power.

    Solar can be embedded in windows of high rise buildings and the like.
    I think photovoltaics have a better future than wind. I don't like what I'm seeing with the headlong rush by the government to suddenly throw money at solar. The new solar plants are large-scale affairs on public lands in our deserts, relying on heat concentration to drive steam turbines, so it's the same old big-business-gets-the-big-bucks sort of federal government largesse, with large transmission losses to populated areas. Meanwhile, Southern California has hundreds of thousands of acres of flat-topped commercial buildings which could have solar panels installed on them. Warehouses and other low-draw operations would produce much more power than they use. That could make a significant dent in the consumption of electricity in SoCal, with minimal transmission losses. I expect to see new ideas and technologies improve photovoltaics by a lot in the next several decades if R&D gets funded, privately or publicly. Meanwhile, the solar generating plants being planned and built are going to despoil more beautiful areas with transmission towers and lines.
    I do use a digital device in my photographic pursuits when necessary.

    In Germany fracking is in the planning too. The discussion about it has already started.

    We not only have a lot of solar cells on roofs (and small dedicated solar fields, I have not come across yet), but also a lot of huge wind-mills all around here in the in-land. The latter are growing as mushrooms.

    The problem Germany is facing is as well getting the produced electricity from the most effective off-shore and coastal wind-mill sites to the customers inland, as well as lacking effective means to store electric energy beyond the current hydraulic stores.

    Hmm then how come people with roof solar panels actually make money off the electric company because their net use is less than their net creation and so the leftover is sent to the electric company meaning they get a check from them for producing energy?

    I think homes could easily run off of solar only, I think it's only large factory and schools and office buildings that would use too much power.

    Anyway there's lots of solutions, people are just not willing to change or implement because its either too inconvenient or less profitable..q

    Yes. In Germany alternative electricity production payment is subsidized by the state. That money again is taken from the consumer by a special electricity tax.

    Recently that subsidizing had to be reduced source-wise, as so many production sites arose.

    In the US we have the same pay back system for solar but no tax

    Well, not exactly. They would need some storage batteries to make it through the night, but it's not too far-fetched. Probably the best solar setup is to be grid-connected to buy at night and sell during the day. The hardest part is that the initial capital costs for solar are pretty high and the payoff very slow.

    I wonder if anyone has come up with some sort of thin-film photovoltaics that are made by multi layer deposits on polyester ??? (ie. Harman could have a nice little earner there).

    Not today. Not tomorrow. And not next week.

    Only time will tell...

    Many photo-chemical manufactures are in some way busy with active electrical coatings on Polyester base. Kodak actually aimed at going into production of flexible solar cells.
