A billion people on solar: India

Figure 6: Solar Sheep (Concentrix Solar PV concentrator plant) Two professors in India have done the math and found that there’s plenty of available land in India (much of it on rooftops) to power its billion people on solar energy alone. And solar uses less water than nuclear or coal, also as we already knew for the U.S.

Today in The Hindu, India can meet energy needs sans N-power: Study,

According to their study, 4.1 per cent of the total uncultivable and Figure 3: 1GWh Land area per energy source waste land area in India is enough to meet the projected annual demand of 3,400 terawatt-hour (TWh) by 2070 by solar energy alone (1 terawatt-hour per year equals 114 megawatts). The land area required will be further reduced to 3.1 per cent “if we bring the other potential renewable energy sources of India into picture”, they claim. They conclude that land availability is not a limiting constraint for the solar source as believed.

Southern Company’s three-legged nuclear regulatory-capture stool

The failed EDF nuke project at Calvert Cliffs in Maryland makes it clearer why Southern Company (SO) was the first company to get a nuclear permit in 30 years: it was the only one big enough and monopolistic enough to pull it off. Even then it’s such a bet-the-farm risk that even “great, big company” SO only dared to deploy its great big huge scale equipment with the regulatory capture triple-whammy of a stealth tax on Georgia Power bills, PSC approval of cost overruns, and an $8.33 billion federal loan guarantee:

  1. a legislated stealth tax in the form of a rate hike on Georgia Power customers for power they won’t get for years if ever. If you’re a Georgia Power customer, look on your bill for Nuclear Construct Cost Recovery Rider. You’ll find it adds about 5% on top of your Current Service Subtotal. Georgia is one of only a handful of states where such a Construction Work in Progress (CWIP) charge is legal thanks to our regulatory-captured legislature. Doubling down on bad energy bets, Southern Company is also trying to use CWIP to build a coal plant in Mississippi.
  2. A captive Public Service Commission that rubber-stamps costs for Plant Vogtle. In case there was any doubt as to the PSC’s role in legitimizing those new nukes, the very next day Fitch reaffirmed Southern Company’s bond ratings.

    Southern Company’s regulated utility subsidiaries derive predictable cash flows from low-risk utility businesses, enjoy relatively favorable regulatory framework in their service territories, and exhibit limited commodity price risks due to the ability to recover fuel and purchased power through separate cost trackers.

    Translation: Georgia Power customers subsidize SO’s bonds and SO shareholders’ stock dividends. The PSC also approved cost overruns being passed on to Georgia Power customers, and those nukes are already over $400 or $900 million, depending on who you ask. What do you expect when 4 out of 5 Public Service Commissioners apparently took 70% of their campaign contributions from utilities they regulate or their employees or their law firms, and the fifth commissioner took about 20% from such sources? Hm, there’s an election going on right now!
  3. An $8.33 billion federal loan guarantee. Even that’s not good enough for SO and Georgia Power: SO is asking for less down payment.

And what if even one of that three-legged regulatory capture stool’s legs went away? Continue reading

Streetlights and Georgia Power @ Hahira 2012-10-01

To get a decent deal on streetlights, a small Georgia city may have to help change the Georgia Public Service Commission. Or, an energy concern in Hahira happened to coincide with a visit by PSC candidate Steve Oppenheimer.

Ralph Clendenin, City Council member, is looking into converting Hahira's streetlights to LEDs or maybe solar. He has discussed that with Georgia Power, which will do it for $250,000 up front. At a savings of $1,000 a month, that would take quite a while to pay back: more than 20 years.

Steve Oppenheimer, running for Georgia Public Service Commission (PSC), found the streetlight issue interesting:

Just like you're looking at options the city might do for better choices for lighting in terms of serving the people and meeting your budget, as Georgians we need that, too.

He indicated that there are more solutions than we're being told.

To me what's improtant are homeowners rights, and we get control over the power rates, because our residential rates and small business rates have gone up about 31% in five years.

He brought up Dublin's solar streetlights, and solar for energy and jobs. He indicated energy was a future source of jobs.

What it comes down to is people like you in this room in the small communities figuring out what pieces do we put together to make our community better for tomorrow.

Afterwards in the entranceway, Ralph Clendenin showed Steve Oppenheimer how he'd figured out that Georgia Power was charging about 73% maintenance above the electricity cost of the streetlights. Oppenheimer said there were many options. Clendenin suggested one:

The option I see right now is, the Commission somehow, has got to change the rules on how Georgia Power… structures payments.

Oppenheimer suggested a way to get there:

We need a commission with some new leadership, with some separation from industry, that doesn't have the apparent conflicts of interest.

Ralph summed it up pithily:

Ralph Clendenin: 73% is that forever payment to Georgia Power.

Steve Oppenheimer: It's a great deal, if you're on the right end of it.
[laughter]

What say we change the end of the stick we the taxpayers are getting from the PSC?

Bill Moyers on ALEC

Bill Moyers takes on ALEC.

Posted yesterday On Bill Moyers’ website, ‘United States of ALEC’ Video Previews

This week, Moyers & Company (check local listings) presents “United States of ALEC,” a report on the most influential corporate-funded political force most of America has never heard of — ALEC, the American Legislative Exchange Council. A national consortium of state politicians and powerful corporations, ALEC presents itself as a “nonpartisan public-private partnership”. But behind that mantra lies a vast network of corporate lobbying and political action aimed to increase corporate profits at public expense without public knowledge.

He said more on Huffington Post Wednesday,

Georgia Power inches towards more solar, trailing New Jersey

If you’re quick, you may be able to sell solar from your roof to Georgia Power. If the PSC approves a pending request. If you get in before that new quota gets filled. And if you’re a Georgia Power customer. The rest of us? Not until the 1973 Georgia Electric Territorial Act is changed. Until then, Georgia will continue to lag way behind New Jersey in solar power.

210 MW is more than 50 MW but way less than 3,000 MW

Walter C. Jones wrote for the Augusta Chronicle today, Georgia Power plans to triple solar power use,

Georgia Power filed Wednesday seeking permission from state regulators to more than triple the amount of solar power it uses to generate electricity for its 2.4 million customers by swapping it for what was already planned from other renewable sources.

What “other renewable sources”?

The Georgia Power plan won’t affect rates because it is based on paying the solar providers what it would have paid the biomass provider, 13 cents per kilowatt hour, which is already figured into customer’s rates.

OK, that’s good, because it means biomass is well and truly dead in Georgia. But it also means Georgia Power isn’t very serious about solar, if all it’s doing is fiddling with accounting for the small amount of power biomass might have produced and not going for the real numbers solar can produce. OK, how many solar megawatts?

Southern Company: let’s do the renewable energy study for Georgia

Mark Z. Jacobson's study shows offshore wind is plentiful from Virginia to Maine Let's do the study for Georgia! Southern Company brags about its private R&D:

Research & Development (since the 1960s)

  • Awarded more than $1.3 billion to conduct more than $3.8 billion of research and development.
  • Qualified for $412 million of investment tax credits for a 21st century coal plant being built in Mississippi.

OK, SO, let's see you do the study to show what we can really do with conservation, efficiency, wind, sun, and less natural gas than we have now. Sure, in the Georgia Bight we do have to contend with hurricanes. But a "great, big company" like SO should be able to focus its vaunted private R&D on that problem and solve it.

Maybe SO doesn't want to do that because the result might show there is no need for any coal plants, nor new natural gas plants, nor any nuclear plants, which would mean Georgia Power would have to give up its nuclear-funding rate-hike stealth tax and SO would have to give up its $8.3 billion loan guarantee. Hey, we might even need to change the 1973 Georgia Electric Territorial Act, and that might damage Georgia Power's guaranteed profit! Nevermind that Georgia Power and SO might make more profit if they got out in front on solar and wind power and a smart grid.

If SO won't do it, how about we elect some Public Service Commissioners and legislators who will? For jobs, energy independence, and profit, oh, and clean air and plenty of water!

All U.S. east coast electricity could come from offshore wind 3 seasons out of 4

Why build nukes when wind can provide 3/4 of our power? While Southern Company claims to be “a company that is engaged in offering solutions, not just rhetoric”, yet does nothing about wind off the Georgia coast, researchers in far California have demonstrated we can get 3/4 of all needed east coast electricity from offshore wind.

Bjorn Carey wrote for Stanford Report 14 September 2012, Offshore wind energy could power entire U.S. East Coast, Stanford scientists say

A new analysis by Stanford researchers reveals that there is enough offshore wind along the U.S. East Coast to meet the electricity demands of at least one-third of the country.

The scientists paid special attention to the Maine-to-Virginia corridor; the historical lack of strong hurricanes in the region makes it a favorable site for offshore wind turbines. They found that turbines placed there could satisfy the peak-time power needs of these states for three seasons of the year (summer is the exception).

“We knew there was a lot of wind out there, but this is the first actual quantification of the total resource and the time of day that the resource peaks,” said Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford who directed the research. “This provides practical information to wind farm developers about the best areas to place turbines.”

Mark Z. Jacobson already worked out a framework for powering the entire world from wind, water, and sun alone. The late John Blackburn, Ph.D., showed us how to power North Carolina with sun, wind, and hydro, plus less natural gas than NC uses now. Now Jacobson is working out the details of implementation.

Europe: no shale gas, more renewables

Europe has no shale gas, so, unlike the U.S., natural gas will not be getting in the way of quickly moving to renewable wind and solar energy.

Barbara Lewis and Henning Gloystein wrote for Reuters 23 August 2012, EU Green Energy Drive Says No To Shale Gas, Looks Towards More Renewable Power Sources,

In the medium term, the value of conventional gas is in providing reliable baseload power to supplement unpredictable renewables, which depend on the sun shining or the wind blowing.

Danish state-owned utility DONG Energy, which has relied heavily on coal-fired power generation, sees a combination of gas and renewables as the way to go.

“We see gas-to-power and wind energy as the ideal mix, together comprising clean and stable energy. Wind energy as the clean energy source, and gas-to-power as the balancing power,” Carsten Krogsgaard Thomsen, DONG Energy’s acting CEO, said.

Meanwhile, Windpower Monthly reported 13 August 2012, Dong issues 2012 profit warning,

Germany Added 543 MW of Solar Power Capacity in July

While we in Georgia were still pouring money down that nuclear pit near the Savannah River, Germany has been getting on with real renewable energy. We could have deployed almost that much solar power with just the cost overruns so far at Plant Vogtle.

Nicholas Brown wrote for Clean Technica 8 September 2012, Germany Added 543 MW of Solar Power Capacity in July,

According to Matt McDermott of Treehugger: “[In] the first half of 2012 Germany has installed just over 4.37 gigawatts of grid-tied solar power. Remarkably just about 1.8 GW of that happened in June alone (perhaps even more remarkable, this isn’t even a record amount for one month in Germany).”

The amount of solar power capacity added in June was much more than July’s, but July’s was still impressive. July’s addition brings Germany’s total installed capacity for the first half of 2012 to 4,900 MW (4.9 GW).

This impressive solar installation rate had a lot to do with Germany’s famous Feed-in Tariffs (FIT), but it also had a lot to do with Moore’s Law, illustrated by that graph of cost per kilowatt rapidly going down.

543 MW? That’s more than the 330 MW of solar the $913 million cost overrun at Plant Vogtle in the first half of 2012 could have bought. 1800 MW in June and 543 MW in July? That’s 2343 MW, which is more than the entire rated 2200 MW output of Plant Vogtle 3 and 4 put together, if they ever get built. Sure, the sun doesn’t shine all the time, but in the years until the nukes ever get built (if ever), how much solar could we deploy at the rate of one Vogtle unit equivalent a month?

Hey, maybe we should cancel Plant Vogtle and deploy solar instead! Maybe Georgia Power and Southern Company will realize their big bet has already gone bad. Or maybe we should elect some Public Service Commissioners and legislators who will get them to realize it.

Industrial Authority goes solar, broadband, and conversational!

The Industrial Authority apparently listened to its focus groups, and discovered that broadband and solar energy are important to attract industry. Andrea Schruijer even recommends conversation, which has been sorely lacking in recent years. Congratulations, Industrial Authority!

Jason Schaefer wrote for the VDT today, Authority analyzes Valdosta business: Broadband, solar power, professional services targeted for growth,

The Authority also plans to work toward the availability of more broadband Internet service and solar power in Valdosta and surrounding communities. These amenities would help support local industries as well as draw new ones to the greater Valdosta area for the creation of new jobs.

That’s a good start. Although it’s not clear from the writeup that VLCIA quite got it about Internet access.

As part of presenting Valdosta as an attractive package for prospective industries, the Authority attempts to ready the land set aside for development before beginning the recruitment process. This means investing in infrastructure, including broadband internet.

“It’s not that we don’t have broadband,” Schruijer said. “What we’re looking at is the technology behind the broadband. We have it in certain areas, but in order for us to grow some of these core targets, such as professional services, we need that infrastructure.”

Well, actually, no, we don’t have broadband. 6Mbps is the fastest most people can get around here, and 30Mbps is the slowest you can even buy in many countries. Plus, it’s not just fast Internet to industrial sites that’s needed: it’s fast Internet access everywhere knowledge-based employees may want to live.

But they’re on the right track:

Because the Authority can’t “buy” industries into coming to Valdosta—though it can offer tax abatements—it is necessary to make sure that new businesses have what they will need before ground is even broken, Schruijer said. To this effect, the Authority will “stimulate the conversation” to actively attract more broadband companies to the area.

A conversation! Now there’s something we’ve been needing around here. And it’s a refreshing change from only a year ago when all we heard was

“Debate is not allowed.”

Maybe the Industrial Authority will be the organization that will show the rest of us how to hold civil discussions about things that affect all of us!

The VDT’s writeup skips quickly over another big change:
