The inflection point for solar energy | David Galipeau | TEDxBrookings

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)

    Thanks for presenting this info.

  2. pst says:

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

  3. Escape Felicity says:

    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.

  4. Tom Tompkins says:

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

  5. Tom Tompkins says:

    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?

  6. Tom Tompkins says:

    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.

  7. Achal H P says:

    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

    Please don't give a talk wearing Crocs!

  9. Peter Chang says:

    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.

  10. Peter Chang says:

    without storage, cheap solar is still, lousy energy, plus storage, still expensive.

  11. Peter Chang says:

    the catch is, after all those green advantages, still not a huge impact on our energy picture. Even solar can solve some of our electricity needs, the large picture is , you gonna still need coal and other fuels for agricultures, mining, steel/cement making, chemicals, etc. and that is , a lot. I think solar will cap after a certain threshold.

    "This talk was given at a local TEDx event…" in the description, sure would be nice to mention the year this talk was given as well as the place (though the uploader was pretty vague about the place as well).
    Play at 1.25x playback speed. 😉 MUCH better.

  13. Michael Weaver says:

    No talk of how we store all this energy for when we don't have sun. How much environmental damage will huge arrays of batteries do and how efficient will they be? Can we get enough storage to handle the load in low sun times. I think the answer at least for now is no. We can use solar to reduce the load but it cannot replace the current grid system. Same goes for wind. There are limits to how far you transmit even high voltage power so we have to keep some other form of energy like fossil or nuclear powered up on the grid and have therefore only partially mitigated the problem. New safer forms of nuclear along with renewables is the best option.

  14. Lekhnath Kafle says:

    Great presentation Dr. Galepeau

  15. brett rasmussen says:

    So many assumptions, most of them wrong, and this guy calls himself an engineer!

  16. angel rodriguez says:

    We need to take advantage of this information and solar technology. We need to make fossil fuel a thing of the past within the next 100 years.
