Why Choose Sustemy?

Sustemy focuses on equipping you with the practical knowledge and skills that help you confidently face sustainability and energy efficiency challenges.


We provide training designed from the ground up for online, on-demand delivery. We know you are not in a classroom, that you don't learn passively, and that you won't learn much sitting through a recording of a two-hour lecture delivered at a university. You can do your course on your phone, on the train, or on the computer on your desk – or both! Our interest is in making it easy for you to learn anywhere.


We focus on verifying that you've actually learned. Take one of our courses, and you don't pass just by watching videos. You have to pass assessment quizzes – and a lot of effort goes into developing the assessments.


Giving you feedback is one of our priorities. Our assessments are structured so that if you get a question wrong, you are shown how to come up with the right answer.


Our social mission is to make quality sustainability and energy efficiency training affordable everywhere with pricing based on the GDP per capita of your country. The effort we put into developing quality courses and supporting students means our training is not cheap, but it is affordable – and affordable everywhere, wherever you are. If you are in India, we don't expect you to pay as much as a student in Indiana. And if you are in Indiana, you'll find our pricing still affordable and comparable with other training providers.
