Scott, sure it's easy and it's expensive. If you are looking just to run a few small things and keep your batteries charged a few hundred $US might do it. Solar power starts at about $5US a watt. Plus the cost of batteries and inverters. Wind power gets cheaper per watt as the size of the generator gets bigger, but you need to be where the wind blows. Now i know that seems obvious, the winds need to blow around 10mph constantly for wind power to be feasible. Here are a couple of sites with FAQ's if you want to read more about it.
