Authors of the bestselling book, Wikinomics, explain how mass collaboration has changed the business scene and pretty much everything else today. The word WIkinomics is obviously a combination of very popular Wikipedia and the bestselling book Freakonomics.

In Wikinomics you will read about Facebook, Wikipedia, YouTube, Flickr, Second Life and other successful online communities and how they are more than just a social network but ended up a successful example of how mass collaboration can revolutionize the world. And true to what it preaches the printed book is only the start.

Adding a renewable energy system to one’s home or business may entail high initial costs but may be the biggest step anyone can take on lowering environmental impact. The high cost anyway is likely to be offsetted by savings or utility costs over the long term. Government has also been offering incentives that can shorten the time necessary to offset the cost of such technology. Once the system is in place, it produces virtually free energy.

The renewable energy system may not be appropriate for everyone since there are certain factors that need to be considered such as the availability of net metering in an area, the types of technologies that will work best in a specific location and the financial options available.
