Energy Returned on Energy Invested (ERoEI) of any energy gathering system is a measure of that system’s efficiency. The concept was originally derived in ecology and has been transferred to analyse human industrial society.« Back to Glossary Index
The pre-alpha version of a lesson is one that has not been peer reviewed yet — however, don’t worry, pre-alpha is good enough to be live! The alpha version is an early version of a peer reviewed lesson that is part of a dedicated evaluation process. The beta version includes almost all of the final content, videos, etc. yet it may still need to be tweaked somewhat.
The reason for making the pre-alpha version live is that we are actively engaging with our ‘early adopter’ crowdfunding students and contributors so that we can build the best course possible. The completed alpha versions of the entire course will be live from the 1st March 2024.
The beta versions will hopefully be released by 1st August 2024. The ‘completed & refined’ release of the RSD Course (English) should be available at the end of 2024. The course will then be translated into other languages — around 10 languages at first, and then more according to demand.
