Program Highlights

Our St. Lawrence College facilities include some of Canada’s most complete laboratories for students to learn how to size, design, and install solar photovoltaic, solar thermal and other sustainable energy systems, for both grid connected and off-grid applications. St. Lawrence College also has a 250kW grid connected rooftop solar array where we walk the talk on the value of renewable energy systems.

In addition to our regular program coursework, over the past few years, we have been able to leverage a variety of programs to provide work experience for students in Texas, Jamaica, and within our own College Sustainable Energy Applied Research Centre (SEARC). Many students have also gone on to Bachelor’s degree programs at a variety of Universities in Canada and abroad.

As energy conservation and alternative energy production become a greater priority throughout the world, governments are playing a larger role in steering the transformation of how our energy is produced and consumed.

This course content allows students to become more aware of the type of involvement government and regulatory agencies have in the energy field and the influence these organizations have on the clean energy industry and the future job market in clean energy. Students are introduced to the theories and types of regulations and policies that apply to energy efficiency and renewable energy projects, mostly from a Canadian perspective. As some of our energy legislation is based on examples from other countries, international energy policy examples are also explored.

The broad and evolving area of federal, provincial and municipal government incentive programs for energy conservation, renewable energy use, and green-house gas emission reductions are discussed. The role of regulatory bodies in the renewable energy sector and the licensing of energy efficiency and renewable energy practitioners are reviewed.
