Energy from the sun is used in many different forms - water heaters, electricity generation, space heating, greenhouses for plants, and others. But what is the ultimate potential for solar energy in a northern country such as Canada? In this book (2010), the extensive use of large scale solar power plants is examined, with a view to the far future when hydrocarbon resources become depleted. Surprisingly, Canada is well positioned to continue to be a major energy producer far into the future by exploiting its greatest under-utilized resource - land. Land that is unsuitable for agriculture or forestry, and that we have in abundance. In Solar Energy and the Future, we see how this land can be utilized to its utmost, by looking at it from a Canadian perspective.
