About Eric Kosak

Eric Kosak I live in a magical time of science and technology in which Merlin himself would be amused. I am just learning about it. A goal of mine for many years has been to learn and understand as much as I can about it, and, yet, everyday I find out something new. I hope I can share this. I believe in being independent; therefore, I enjoy reading on a variety of things. For instance, what can I do to improve the energy consumption of my house? How can I reduce the negative impact on my health due to the things I buy and do? Can I improve my life by choosing one type of energy over another? How can I repair a leak in my bathroom? What do I need to do to grow my own vegetables? To improve the world, my mom always says, we start at home. I have learned that to succeed at something I must fail many times, and with each failure I learn something, and I also try to live by the golden rule of doing unto others as I would like them to do unto me.

A couple of weeks ago, I made an EPS prediction for Tesla’s second quarter. At the time, I said, “the key disclosure this quarter will be the number of cars produced. I am expecting almost twice as many cars produced in the 2nd quarter compared to the first quarter. My EPS prediction relies on cars produced.”

On Wednesday, May 9, 2018, history was made. The California Energy Commission unanimously approved the requirement that all new homes and low-rise apartments built from 2020 onwards include solar panels. The approval was supported by builders, utilities, and solar manufacturers. Now, say it with me — hip hip hooray!


Peeking Behind Tesla’s Labor Curtain

July 1st, 2018 | by Eric Kosak

In the last two articles (that I wrote exclusively for CleanTechnica), I explored Tesla’s break-even level and its cost of capital. On this occasion, I would like to explore Tesla’s cost of labor


Peeking Behind Tesla’s Capital Curtain

June 18th, 2018 | by Eric Kosak

During Tesla’s last conference call, concerning the first quarter of 2018, Mr. Deepak Ahuja, Tesla’s Chief Financial Officer (CFO), while answering a question from Rod Lache, an analyst at Deutsche Bank Securities, Inc., said: “Rod, we are very CapEx-efficient, overall. Let me just start from that point. And if we look at our depreciation costs on a per unit basis at steady run rate of 5,000 or so cars per week, we are in my mind well below most of our competitors – well below $2,000 per unit depreciation cost.”
