If you live on the waterfront, you should check out this homemade wave power generator. This is really cool to see in action. Some countries are really moving on wave power, and I can see why.
A company in Norway, WAVEenergy AS has developed a truly revolutionary system that could teach other countries about the value of wave power.
I would try to explain it, but the description and image on their site do it much better justice than I could. It will be exciting to see how wave power is harnessed over the next couple of years. For the moment, I am just happy to see that people are taking matters into their own hands and seeing results.
If you are not on a waterfront, are interested in getting off the grid, yet the cost of installing hardware to support solar power is out of reach, you may be able to rent them soon at a much lower cost than ownership: http://news.com.com/Breaking+the+mold+in+solar+power/2100-11392_3-6161136.html
