Canada.com has posed quite a few questions for the reader today as it begins to look at the questions concerning renewable energy sources like solar energy, solar power and solar panels; the question is no longer "Who has seen the wind?" but "Who owns the wind?"

Canada.com  writes that in the developing world of renewable energy, can neighbouring wind farms steal from each other? What if you put solar panels on your roof and your neighbour plants a tree that blocks them from the sun? Do you have a right to solar access?

Canada.com writes that these aren't just philosophical questions, but real-life challenges that are already lining lawyers' pockets in Canada and Europe.

"Who owns the wind over land, and at what height does that ownership start?" said John Marrone, director general of the CANMET Energy Technology Centre at Natural Resources Canada.

"Those are the kinds of issues that emerge. We never had to worry about these things, and now we do."
