The inflection point for solar energy | David Galipeau | TEDxBrookings : solar energy economics

Abundant Energy

This talk was given at a local TEDx event, produced independently of the TED Conferences. Solar energy has been hailed as the future of energy for decades. Finally, solar energy has reached the inflection point where it not only makes technological sense, but also economic sense.

Dr. David W. Galipeau is the Harold Hohbach Professor of Electrical Engineering and the Coordinator of the Center for Advanced Photovoltaics and Sustainable Energy; and Electrical Engineering MS and Ph.D. graduate programs at South Dakota State University. He was also the program lead for the Alternative Power Technology (APT) Program supported by the Department of Defense. While at SDSU, he has been the PI or Co-PI on over forty funded research projects, including twelve major NSF awards for over M and eight SBIR-STTR awards. He has published over 100 research papers, given numerous presentations, and established a spin off business. He was also Co-founder of the Center for Advanced Photovoltaics and Sustainable Energy.

About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

  1. if you want to know how to make some of your DIY kinds of stuff yourself, just go to an Avasva website. There you'll find your answers 🙂

  2. Nice movie. However you should take instructions from Avasva website if you want to learn how to make it easily.

  3. I wonder why this gentleman has not told us that today China is the world leader in solar power ?

  4. 1 You need to stop saying 'actually'. It makes you sound retarded.

    2 The problem is fossil fuel is TOO CHEAP.
    If we price in the damage to environment, solar is much cheaper.

  5. A lot of businesses and universities are going solar just for the economic benefits. Money will drive the conversion to solar.

  6. Oh and on a cost comparison, make sure all illness and deaths from fuel production are included. How many deaths have been caused by solar?
    Also how many spills and catastrophes has solar caused compared to fossil fuels?

  7. If you put all fossil fuel electricity producer together, how much land would that cover, oh and include all the refineries and mines, hmmm I wonder.

  8. Thorium Molten Salt Reactors and Nuclear fusion need help from innovator like David Galipeau.

    Solar Energy has limitations:

    Dilute : need large area * Seasonal variations – Need fossil power backup * Intermittent on hourly basis – need battery/pumped hydro backup * Location specific

  9. don't forget, a 600MW capacity of thermal power plant by gas/coal, etc, is not the same as a 600MW solar PV plant, the 600MW coal plan can produce literally that amount of power anytime, but not the case for solar, so, even with storage, based on different locations and sunshine, to reach the same capacity as a 600MW typical coal plant, you may need a solar PV plant of at least 2X, or 3X and even more, already taken storage into account.
