In the broadest sense of the word, energy is a substance’s capacity to do work or produce an effect, such as burning coal to create heat. Canada is home to vast quantities of both renewable (e.g. wind) and non-renewable energy sources (e.g. oil). This collection gathers all of The Canadian Encyclopedia’s articles relating to energy, from various types to the means by which they are sourced.
Tidal energy is a largely untapped, renewable energy source based largely on lunar gravitation. While the potential of tidal hydroelectricity has long been recognized, compared to river dams, tidal power projects are expensive because massive structures must be built in difficult saltwater environments.
