    White Pass & Yukon Route

    The White Pass & Yukon Route railway was built to meet the demand for transportation to the gold fields of the Yukon River basin during the Klondike Gold Rush. Completed in 1900, it was a feat of engineering and one of the steepest railways in North America. It ran 177 km from Skagway, Alaska, to Whitehorse, Yukon. Today, tourist rail excursions run on a portion of the original line.

    Wind Energy in Canada

    Wind energy is energy obtained from moving air. The motion results from the heating and cooling of the Earth; thus, wind energy is an indirect form of solar energy. It is normally turned into useful energy by the action of wind currents on moving surfaces such as the sails of a ship or the blades of a windmill. Wind energy is one of the oldest forms of energy used to supplement human muscle.
