In honor of Earth Day, I have posted a new type of puzzle based on constructing wind farms.

Please remember that every day is Earth Day. We need to take care of our planet, because it is the only one we have. To find out how you can help solve the global climate crisis, go to The We Campaign, a project of the Alliance for Climate Protection.

To buy electricity generated from renewable resources, like wind power, contact your local power company. If they only generate electricity through the use of fossil fuels: 1) encourage them to offer more choices; 2) contact your national, state, and local representatives; and 3) buy renewable energy credits.
