- A Joint Production of the USC Urban Growth Seminar Series and the Schwarzenegger Institute for State & Global Policy.
Over eighty percent of the energy used worldwide today is from fossil fuels. That’s a changing paradigm though as renewable energy continues to gain momentum, and proven technologies such as solar power are rapidly growing more cost effective and efficient. Join Dr. Buttgenbach for this presentation as he explains why photovoltaic (PV) power plants are becoming mainstream, and what economic and technological factors are driving this growth. Topics discussed will include national and global renewable trends, irradiance patterns, solar pricing vis-‐à-‐vis natural gas, energy storage, distributed versus utility generation, and more. This session will appeal to renewable energy experts and novices alike.
Speaker:
Tom Buttgenbach, Ph.D.
President and Co-Founder, 8minutenergy Renewables
Discussants:
Detlof von Winterfeldt
Director, Center for Risk and Economic Analysis of Terrorism Events
Professor, USC
Bonnie Reiss
Global Director, Schwarzenegger Institute for State & Global Policy

He brings over 20 years of executive management experience in large-scale solar PV, land entitlement, project development, M&A, and capital structuring and origination. Tom has led transactions totaling over $5 billion involving over 15,000 acres of land development, and closed over 1,400MW in power purchase agreements.
Prior to co-founding 8minutenergy, he was a successful entrepreneur and fund manager working on Wall Street with Alliance Bernstein, a $500 billion fund, leading the investment banking group of RCLCO, where he has transacted and developed large scale real estate development projects in the US and Mexico, and as a project manager for McKinsey & Company in Europe and the US.

Great to see that Avasva has new instructions to save my money and energy to build it.
If I want to cite this talk in something I write, how am I supposed to give a date for this? There is a date for when it was uploaded, but nothing about when the talk was given. USC Price really slipped in not putting that in the notes.
That said, that's probably left out most of the time. And there's a bigger issue. UA-cam should have a more structured presentation of tags for the information about all its video clips. It's always been just a free-format text area, and that's not good enough for many purposes.
I agree/ disagree with the first speaker for the simple reason, I am an average person who does not want to be dependant on any large companies for my power. I would rather have my own roof top electricity from Solar Panels and my own battery bank. I am very sure that this is the way the World is heading to (battery homes in Australia especially Perth is a good example) considering the advances in PVs and Battery Technologies.
Wake up, mark my words, you WILL see diminished revenues from your Solar Cell company in just about 5 years time from now. We do NOT need more power lines but we DO need more roof top Solar Panels that can function on its own. Considering a conservative growth of 5% increase in Batteries power density and 7% decline in its costs, we will hit the parity with conventional power which means an average person will have Solar Panels on his/her roof top. Just look at Australia's Battery homes and how their utility companies are changing/ adapting their business models for their survival.
when the price gets down for home roof everyone will go of grid. the reason is there is a lot of electicity resistance in the grid.. so it's cheaper to make it where you use it
Long term I agree, thats the way its heading. The sunny part of the world already has it basically just needs a bit cheaper batteries.
For the not so sunny parts efficiency needs to increase a lot still, and part of the world I don't think PV allone will ever be enough. Also cities are a diff animal, there needs to be wind and solar farms to power cities.
You are right...15% of power lost transmitting the power from plant to user.
But on average the capacity of solar is 20%, since backup power is required for all home designs. It isn't the on days which the energy department calculates, but the possibility of down days due to weather.
Fossil fuel 65%
Solar 20%
Wind 35%
Water 40%
Nuclear 90%
en.wikipedia.org/wiki/Capacity_factor
A number of sites vary a little on those numbers, but remember...we're talking averages.
These guys are selling large-scale plants. They want to keep us dependent on them for our energy needs. Rooftop solar cuts the chain from centralized production.
Buttgenbach addresses scale in the video around the 27min mark. Ideally we would all benefit from rooftop solar and home batteries, but as a home solar pro the technology is too technical for most to install and manage.
No mention of the vulnerability of the existing grid to disruption. This presentation is still focused on the grid as is, when are we going to think about the existing buildings, direct current and microgrids and the role of DER in the future grid.
As you build up the sections. marry them to a 359 MW dynamo for long distance distribution.
One problem in California electric utilities are a state sponsored monopoly with no government oversight. The only answer is people need to take back their power. On site power generation. The mega answer brings mega problems.
Batteries are going need to be economically viable soon to solve the Duck curve.
I agree with that. He tried to ignore the battery problem. I think that's the key to green energy.
I'm wondering that if it is possible to set the solar panels in mounted poles instead of installing these in the surface so that it would save the land (occupied by the huge number of panels) for alternative use or plantation.
I think if all the panels were elevated for at least 70 feet above the surface and using transparent panels, it would have saved a huge land to be used for agriculture or housing.
Transparent panels. The idea is to catch the light and use it for energy.
We won't need that much land for pv's.
Roofs will carry most of the load, especially huge commercial buildings can carry a lot of pvs.
so sad so few people there
So the first guest speaker received a PhD in physics which would relate to solar energy engineering but the rest of his back ground is like sending a logger to weld a submarine.
Texas theres none of that? The state leads the nation in Wind Power production. What study did you look at?
Interesting...do you have a link for that stat?
He is talking about incentives for large-scale solar projects. Lobbyists from Enron got special subsidies for wind energy in the state of Texas, because Enron was a big wind energy company, but those subsidies don't apply to solar.

Lol if you want part of your fence paid for make sure your property is on the border
Electricity should be a public service, not a commercialized company.
Problem with fundamental changes in power is that solar costs me as a consumer, today, around $4 a watt. I can't begin to afford that. My present "fossil fuel" supplier charges me $.12.5 a watt. Not to mention the toxic manufacture of the end product, with sixteen poisonous chemicals resulting from fabrication.
My kids and I experiment with the technology, but....
Storage costs have dropped radically, as companies are mass manufacturing Lithium batteries, and our exeperience so far with them has been a much longer discharge cycle. My house uses on average 7KW a day, with peaks during evening when I'm cooking and the AC is on. I have to plan for that with storage...and a complete system costs around $23,000. On stormy days, the battery pack runs out. Being on the grid isn't an option if people want to be self sufficient...
Wind power isn't a good alternative, as those blades (according to the department of interior) kill about 15,000 birds a year, including sever protected species like Bald Eagles. Wouldn't it be great if we all had rivers by our homes?
You are spewing so much misinformation that you are either a paid troll or very stupid. Your utility is charging you $0.125 per kWh (not watt), so your are comparing apples and oranges when comparing the cost of installed watts of residential solar and the cost of electricity per kWh from the utility. In many places, residential solar is cost competitive with utility electricity. You are using outdated pricing and looking at off grid, then comparing that to grid electricity, which isn't a fair comparison. Look the price of a diesel generator and the price of diesel and then compare it to your off-grid solar system and you will find that solar is cheaper per kWh if you need to be off-grid for more than a couple hundred hours per year.
Peer reviewed studies find that wind turbines kill fewer birds per MWh than fossil fuels, once you include birds killed by climate change in the equation. Buildings, power lines, and cats kill far more birds than wind turbines.
Interesting but boring.
