Well I finally did it! My husband let me have $40 and I used that to go solar-panel shopping. As a woman I felt the lure of shoes, skirts, and hair accessories, but think about it: if you think something big is gonna happen, or if you are one of those who think 2012 is the end of the world (I don't), or if you just want to be safe rather than sorry... why would you buy shoes when you could buy solar panels? Shoes won't produce electricity or heat your house in winter or provide light to your plants when growing anything is impossible.
In my opinion wind power is a better way to go (more productive, and cheaper to assemble) but if you have the extra money, make an investment in your survival, rather than your looks!
