Solar is coming —Michael Noll

Received yesterday on Solar tipping point within a few years. -jsq
In line with comments made by Steven Chu:

Solar cheaper than fossil fuels in a decade, says Steven Chu, by Christopher Mims, 3 November 2011.

Solar power will be cheaper than fossil fuels at some point between the end of this decade and 2026*, said U.S. Secretary of Energy Steven Chu

as well as a recent Op-Ed piece by Paul Krugman:

Here Comes Solar by Paul Krugman, 6 November 2011.

…progress in solar panels has been so dramatic and sustained that, as a blog post at Scientific American put it, “there’s now frequent talk of a ‘Moore’s law’ in solar energy,” with prices adjusted for inflation falling around 7 percent a year.

This has already led to rapid growth in solar installations, but even more change may be just around the corner. If the downward trend continues — and if anything it seems to be accelerating — we’re just a few years from the point at which electricity from solar panels becomes cheaper than electricity generated by burning coal.

And if we priced coal-fired power right, taking into account the huge health and other costs it imposes, it’s likely that we would already have passed that tipping point.

-Michael Noll

I added the blockquotes and the Moore’s Law link. Seems to me physicist Sec. Chu must be looking only at the sticker price, while economist Krugman is also looking at other costs and at externalities not currently included in the sticker price, yet still costing us in other ways. Add in the costs of wars for oil and I wonder how long ago solar already became cheaper than oil….

Jerome Tucker honored at Civic Roundtable

The Civic Roundtable honored Jerome Tucker for some of the many things he has done for Lowndes County and south Georgia. And as usual he hit the nail on the head.

Dawn Castro wrote for the VDT yesterday:

“We do have one of the best communities,” Tucker said. “The toughest part of me standing before you is knowing how much better we could be if all the little groups would work together.”
He also said:
“I am still blessed to have my dad with me,” Tucker began. “He always asks me, ‘Where have you been?’ and ‘Did you do any good?’
Here are a few good things Jerome Tucker has done recently: Continue reading →

Solar tipping point within a few years

Why is anyone still building fossil fuel (or nuclear for that matter) power plants when solar is within a few years of being cheaper? In other words, by the time those other plants can be built, solar is very likely to be more cost-effective?

Marcia Goodrich wrote for physorg yesterday, Affordable solar: It’s closer than you think,

It’s a matter of economics. A new analysis by [Michigan Technical University Associate Professor Joshua] Pearce and his colleagues at Queen’s University in Kingston, Ontario, shows that solar photovoltaic systems are very close to achieving the tipping point: they can make electricity that’s as cheap—sometimes cheaper—as what consumers pay their utilities.

Here’s why. First, the price of solar panels has plummeted. “Since 2009, the cost has dropped 70 percent,” says Pearce. But more than that, the assumptions used in previous studies have not given solar an even break.

“Historically, when comparing the economics of solar and conventional energy, people have been very conservative,” says Pearce.

It’s not just that the cost of equipment keeps dropping; older panels remain more efficient than most previous estimates:
For example, most analyses assume that the productivity of solar panels will drop at an annual rate of 1 percent or more, a huge overestimation, according to Pearce. “If you buy a top-of-the-line solar panel, it’s much less, between 0.1 and 0.2 percent.”
There’s more in the news article, and in the journal article it references, A review of solar photovoltaic levelized cost of electricity, K. Brankera, M.J.M. Pathaka, J.M. Pearce, Renewable and Sustainable Energy Reviews, Volume 15, Issue 9, pages 4470-4482. doi:10.1016/j.rser.2011.07.104

Financing for renewable energy projects

Most of the cost of a corporate or personal renewable energy installation can be funded through federal and state rebates, but the remainder is what stops most people. Here is what I know about that. There are many other sources of information.

Federal 30% and Georgia 35% rebates add up to 65% (see below under DSIRE). That’s for solar (PV or hot water), wind, and some other related items.

The other 35% is what stops most businesses and people. 35% of a $25,000 house solar system is still $8,750. People like that it will pay itself off in 9-15 years, but most people don’t have $8,750 to invest.

That’s a business opportunity for some enterprising local bank or banks. As Dr. Noll has explained, if you pay for that remainder yourself, the system will pay itself off in about 9 years. If you get a bank to finance it, more like 15 years. And local banks currently require collateral other than the system itself (they like real estate as collateral). The simplest business opportunity is for a local bank to accept the solar equipment itself as collateral. After all, it’s worth 65/35 or 185% of the total loan amount.

The Georgia Solar Energy Association (GSEA) can probably tell you more.

Who to contact about nuclear vs. solar

Somebody asked who to write about the nuclear costs Georgia Power is passing through to customers. Here’s the contact page for the Georgia Public Service Commission.

PSC Commissioner Lauren McDonald has been the most vocal about wanting Georgia Power to do solar. Commissioner Chuck Eaton and Tim Echols have both said in public they want more solar. PSC staff member Tom Newsome tried to get gapower to accept a better nuclear profit deal.

Don Parsons, chair of the energy committee of the Georgia House of Representatives, wants to write an energy plan for Georgia. A real one; not that bogus one from 2006 that nobody followed anyway.

Doug Stoner, Georgia State Senator, has said that Georgia Power wasn’t building nuclear plants with private money; they were using public money, and that even a public utility is a subsidy. So it appears he gets it.

Scott Holcomb, Georgia State Representative, wants a state energy policy, and has said:

Our lack of an energy policy is an absolute Achilles heel of our national policy.
So we should get on with a real energy strategy for Georgia.

Click on the pictures of each of the legislature members for their contact information. Even better, contact your state representative or senator. Or federal, since I think the new Plant Vogtle construction gets federal subsidies, too. Or write your local newspaper, or your local TV station, or the AJC.

Calculate how much Vogtle is costing you —Mandy Hancock

Received yesterday, related to Georgia Power forges ahead with expensive nukes. -jsq
For those of you concerned about nuclear energy, here are some quick, meaningful actions you can take today. Maybe you aren’t concerned about nuclear energy. I bet you ARE concerned about $$$$.

Learn more about how Georgia Power is getting your money at the state and federal level. All US taxpayers all over the US are basically cosigning a loan for $8.3 B for the Vogtle reactors. Simultaneously, Georgia Power is raising your electric rates to fund the pre-construction costs by pulling the same advanced cost recovery scheme as SC and FL. You can learn more about the controversy surrounding the loan guarantees here

He is in the business of selling energy, not saving it. —Michael G. Noll

Received yesterday on Georgia Power forges ahead with expensive nukes. -jsq
Thanks for posting this John!

Mr. Bowers’ visit and his comments are almost comical, particularly his quote that “the government is stimulating for renewables to give them a running chance but, when you remove them, the question is can they run on their own two feet?”

A good question! Fact is that neither coal nor nuclear would be able to “run on their two own feet” if it wasn’t for the large subsidies both have received for decades. Now these are nicely hidden subsidies so that the average consumer thinks he is getting a bargain, without realizing that it is us, the consumers, who have actually paid for this “inexpensive rate”.

Yes, I do have solar

Here’s my LTE in the VDT today. -jsq
A letter last week asked, “Do you have solar energy yourself?” Why yes, I do. When we installed solar panels on our farm workshop in 2009, the closest certified solar installer was in Marietta. There were only four in the state. Now there are forty. Georgia may yet catch up with North Carolina and even New Jersey!

Hannah Solar had all the paperwork ready when Okra Paradise Farms applied for a USDA REAP grant for more solar panels a few weeks ago. Much to our surprise,

Georgia Power forges ahead with expensive nukes

Would you buy two new nukes from a company that ran over budget by a factor of 13 last time it built nuclear reactors at the same site? When one of those reactors got shut down for days a couple mnths ago? When another reactor even closer to us was discovered leaking radioactivity into our aquifer? A company that got the state to agree it could keep all its profit and socialize any cost overruns by passing them on to you, the customers? Well, Georgia Power CEO Paul Bowers thinks you should trust such a company to build nukes for gapower’s profit you!

Today in the VDT David Rodock wrote, Georgia Power discusses nuclear, solar, energy costs

Georgia Power president and CEO Paul Bowers visited Valdosta late last week to talk nuclear energy, solar and what the company has been doing to cut energy costs for their customers.
Yet another dignitary visits without telling the public first.

Anyway, much of the story is about how cost-effective and safe Continue reading →

Do you have solar energy yourself? Why yes, yes, I do

Grady Blankenship wrote a LTE in the VDT Wednesday, in which he asked “do you have solar energy yourself?” Why yes, yes, I do. And I have some questions for everyone at the end.

Back in 2009 we installed solar panels on our farm workshop. At the time the closest certified solar installer I could find was in Marietta. Four years ago there were 4 in the state. now there are forty. And that’s in a state that’s trailing North Carolina and even New Jersey in solar installations.

Also, I applied some weeks back for a USDA REAP grant for solar for Okra Paradise Farms. Much to our surprise, last week we Continue reading →
