Global warming and climate changes across the globe are the subjects of many international discussions. With development happening so fast and fiercely, it is high time that we introspect and find ways and means to control the adverse effects the global development is posing to mankind with respect to change in environment as well as depletion of nature’s resources. Today, energy auditing is gaining importance as the energy auditors are those who are engaged in the job of controlling the energy utilisation. There are various energy audit training courses available. The energy auditor training courses are broadly of two types. One type of energy audit certification course touches upon the various aspects of energy auditing while the second type of energy auditor certification course is lengthier and also costly. It goes into the details of energy audit certification. The other basic difference between the two energy audit training courses is that the simpler one deals mostly with houses and other simpler properties while the second one deals with commercial properties. The energy auditor training courses also differ in the type of people, budget and also the equipments involved. While some of the institutes offer the two energy auditor training courses separately, there are others where a combination of both is also available.
