    The engineering of a battery powered device requires power consumption to be kept to a minimal. This criteria becomes less important in a plug in device as a result the engineer of the device is less inclined to ensure that it consumes as little power as possible. Plug in devices also often consume power even then they are turned off, this is called phantom power consumption. The amount of phantom a plug in device varies from device to device but regardless it adds up over weeks, months, years.

    You are correct in your thinking, you just didn’t put “lazy” product designers into consideration. :)

    It is if you have strong electric/wiring skill. If not it is best to let someone do it for some of the regulations are not as intuitive or obvious as you may expect them to be. There is a book

    If you want to do it yourself you can check out this book:

    Photovoltaics design and installation manual : renewable energy education for a sustainable future / Solar Energy International.

    ISBN 0865715203

    I believe you are referring to this:

    https://www.nanosolar.com/

    It is a flexible solar cell printed on thin sheets of aluminum which cn be as thin as aluminum foil. I don’t know if it is commercially available yet.

    I dispose of my Compact Fluorescent(CF) bulbs like it is hazardous waste. There is a hazardous wast disposal/recycling site in my city, Portland, and at my work there is a bin specifically for Fluorescent light tubes. See what you can find in your area.

    Its better to play it safe on this one. Soon we will have LED bulbs that will practically last forever.
