In Canada the 2 basic methods of producing electric power are hydroelectric generation, based on the energy contained in flowing water, and thermal generation, based on the production of steam.

The term "energy" is often used interchangeably with the term "power," but incorrectly so. Energy is defined as the capacity to do work and is measured in joules (J) or watt hours (1 Wh = 3600 J).

CANADIANS ARE now committed to the reduction of greenhouse gas emissions under the Kyoto Protocol, even though Ottawa may not have a well-developed plan. But Dean Scammell does, and he's a good six years ahead of the government. In 1999, Scammell started building his 2,400-sq.This article was originally published in Maclean's Magazine on February 28, 2005

Hydraulic fracturing is a technique used in oil and natural gas production. It releases otherwise irrecoverable resources from certain geological formations by injecting water and additives at high pressure into the ground to create microfractures in the rock. Hydrocarbons can then flow through these fractures into a well. It has become controversial because of concerns that the technique, and well-drilling activity associated with its use, threatens groundwater, surface water, air quality, and other environmental values. Common in Alberta’s oil patch since the 1970s, the practice expanded greatly in this century, triggering gas rushes in British Columbia and Saskatchewan and resistance in several other provinces.

Hydroelectricity is energy produced from flowing water. The amount of energy produced depends on volume and speed: the more water moving at a fast rate, the more energy produced. For this reason, many hydroelectric stations are built near waterfalls. To produce energy, water is directed toward turbines — sometimes with the help of a dam — causing them to spin. In turn, the turbines make electrical generators spin and electricity is produced. It is a renewable, comparatively nonpolluting energy source and Canada’s largest source of electric-power generation.
