More efficient geothermal

LSB Industries have created the Climate master. This is a geothermal heat pump that's much more efficient than any other out there. EER (energy efficiency ratio) is used to measure how good a system is. The Climate master gets a rating of 40, while the top systems before had a rating of 30. At the moment this isn't a big deal because the high initial cost doesn't make the long term benefits economically worth it. Despite most likely not being a major economic success, this does mark a major step forward for energy efficiency in the field of heating.

I chose this article because I want to work on alternative energies as a career. The problem of trying to make things more energy efficient has interested me since I was 8 so I enjoy these sort of break advancements. This article isn't that well written. My main issue with it is that it doesn't seem to have a target audience since it explains what EER is, yet seems to assume the reader understands specifics of heat pumps such as "variable speed compressor pumps." I would have enjoyed the article much more if it had a better explanation about how the new pump worked.
