Nuclear energy

Introduction

According to surveys by the United Nations and other organizations, Canadians enjoy one of the highest standards of living on the planet. Our comfortable lifestyle has been achieved despite harsh winters and vast distances between population centres. Much of our nation’s success depends on reliable, convenient and affordable supplies of energy, including electricity generated in nuclear power plants.

In our offices, farms and industries, electricity sustains our work on computers, telephones and machinery. At home it powers our appliances, heating and entertainment equipment. Electricity provides many benefits, but its generation and transportation also have impacts on environment and human health.

Nuclear energy is an important component of Canada’s electricity sources. There are currently 22 nuclear power reactors in Canada which are operated by public utilities and private companies in Ontario (20), Quebec (1) and New Brunswick (1). Of the 22 reactors installed, 17 are operating.

In 2004, nuclear energy provided about 15 per cent of Canada’s total electricity needs (almost 50 per cent in Ontario). Nuclear energy is a virtually atmospheric emissions-free means of generating electricity.
