Solar powered lights

I love how technology nowadays can be so helpful with just about everything. Whenever I go to expo meetings, I enjoy looking at new inventions because, seriously it just blows the mind. Very entertaining and yet it can be very helpful with our everyday lives. One that really amazes me are solar powered homes and solar powered street lights as well. It's pretty amazing how they came up with this, you know. I've read about this one and compared to regular street lights that need a lot things to secure one in place like trenching and wiring unlike Solar powered lights do not need any of those! Just think, if everything in this world is using Solar powered lights, you can just imagine the energy we will be saving. Very eco friendly if you ask me. One day, maybe I can afford one for my home as well. I have also watched TV shows about Solar power, and most families say it was really worth the investment and they saved a lot in a year! wow, that is truly awesome.
