Wind for 1/3 of Georgia electricity, plus solar

“Georgia has about 14.5 gigawatts of feasibly developed offshore wind energy potential–enough power to provide one-third of Georgia’s current electrical needs.”

And the wind blows at night when the sun doesn’t shine. Add solar for the peak power day, and there’s no excuse for coal, nuclear, or natural gas.

Georgia Power and Southern Company know this. When will they act on it?

Actually, green solar power is winning

An article that dismisses without investigation the fastest growing industry in the world, solar power, after solar has become cheaper than any other energy source, is not a serious article.

Richard Smith wrote for Truthout 9 January 2014, Green Capitalism: The God That Failed. Sure, there are lots of good points in there (such as we need a carbon tax, but it’s not enough), but given that only 90 companies account for 2/3 of GHG emissions saying we can’t change that without crashing the world’s economy is like saying we can’t deal with horse manure in cities in 1900 without crashing the world’s economy, and people did say things like that back then.

Most of the world’s oil and gas is used to produce power, so once we convert to solar and wind, we’ll have plenty of remaining petroleum for other uses such as lubrication.

Saying in 2014 that solar and wind can’t power the world is like saying in 1994 that Continue reading →

Organic battery with no metals –Harvard SEAS

Solar already provides peak power at peak load, and through distribution is resilient, and that plus ever-decreasing prices will drive solar deployments up exponentially for a decade or so yet. If we add an inexpensive metal-free battery, solar will take over even faster. And that’s what Harvard’s School of Engineering and Applied Sciences has just published as a discovery.

Harvard SEAS PR of 8 January 2014, Organic mega flow battery promises breakthrough for renewable energy: Harvard technology could economically store energy for use when the wind doesn’t blow and the sun doesn’t shine,

The paper reports a metal-free flow battery that relies on the electrochemistry of naturally abundant, inexpensive, small organic (carbon-based) molecules called quinones, which are similar to molecules that store energy in plants and animals.

And much less expensive, reported CBC News 9 January 2014, Continue reading →

Utilities desperate to shade solar power

The same Edison Electric Institute that warned electric utilities that distributed solar is already eating their lunch has codified a net metering talking point that utilities are pushing to try to shade solar power. It’s not working.

Power play: Utilities want solar users to pay up Mark Koba wrote for CNBC yesterday, Power play: Utilities want solar users to pay up,

But some experts say the mere fact that utilities— which generate $360 billion a year in energy sales—are battling with solar indicates the threat it now poses to them.

“The success of solar power is forcing utilities to rethink their business model and push for the changes,” said Franc Del Fosse, an energy industry lawyer and partner at Snell & Wilmer. “If you have an individual putting solar panels on the roof, it’s easy to suggest that a utility is making less money.”

The effort for higher fees on solar panel users could backfire, Continue reading →

Solar is now competitive with … natural gas –Crossborder Energy study

Colorado, California, North Carolina: when will Georgia catch up in solar power? What will it take to get the Georgia legislature to realize all Georgians will benefit economically from much more solar power than GA PSC in July required Georgia Power to buy? And why should we permit a methane gas pipeline to gash through Georgia to profit executives in Houston and Juno Beach, Florida when we could be deploying solar everywhere in Georgia for local jobs, profit, lower electric bills, and clean air and water?

Here’s the study that showed solar benefits outweigh costs in North Carolina, The Benefits and Costs of Solar Generation for Electric Ratepayers in North Carolina, by R. Thomas Beach and Patrick G. McGuire for Crossborder Energy, 18 October 2013.

Wholesale solar PPA prices provide perhaps the most dramatic evidence of the continued decline in solar PV costs. Solar PPA prices have fallen dramatically over the past several years, to the point that, in some regions of the U.S., solar is now competitive with other generation resources, including wind and natural gas. Xcel Energy in Colorado recently announced that it is proposing to add 170 MW of utility-scale solar to its system, with its CEO stating “[f]or the first time ever, we are adding cost competitive utility scale solar to the system.”33 The California electric utilities make public each year the average PPA prices for renewable contracts approved by the CPUC in the prior year. Figure 3 shows the trend in the prices for their solar PV PPAs; CPUC contract approval can occur up to a year or more after bids are received, so the figure is indicative of prices through roughly 2011.34 2012 solicitations for solar PPAs in California in the 3 MW to 20 MW size range through the Renewable Auction Mechanism (RAM) have yielded market-clearing prices in the 8 to 9 cents per kWh range.3

The Lawrence Berkeley National Lab (LBNL) conducts and publishes regular national surveys of the installed costs of solar PV; these surveys include Continue reading →

Solar benefits outweigh costs in NC

And the same is true in Georgia, despite Georgia Power and Southern Company.

John Downey wrote for Charlotte Business Journal 23 October 2013, Study: Solar benefits outweigh costs in NC

An independent study published by a nationally known energy consultant asserts that adding 500 megawatts of solar generation in North Carolina would save utility ratepayers about $26 million annually.

It notes the gains from solar projects — such as lower transmission and distribution costs, avoided emissions, lower losses of electricity in transmission. The study calculates that such benefits outweigh the costs by 30 percent to 40 percent.

Update 2017-04-25: Energy NC seems to have removed or moved its copy of that report, but fortunately SEIA lists it on a backup website, and I’ve linked it into the quotation above, plus a copy on the LAKE website. SEIA also lists many other studies for other states, such as one for Virginia which is on the MDV-SEIA website, and now also has a copy on the LAKE website. For Georgia SEIA lists the testimony of GSEIA before the Georgia Public Service Commission in 2013. For Florida SEIA lists only a very old (2003) study with a broken link, which can be found as a google book, but now would mostly be worthwhile as a museum piece. Duke’s own actions in Florida in 2016 and 2017 indicate Duke Energy knows the sun is rising even on the Sunshine State.

The study considered two intertwined solar methods: Continue reading →

Nash County, NC has agendas and minutes for many local boards online

A county no bigger than Lowndes County has agendas and minutes online for its Board of Commissioners, Board of Health, Local Emergency Planning Committee, Board of Adjustment, Board of Elections, Social Services Board, and yes, its Planning Board. Why can Nash County, NC afford this yet Lowndes County Chairman Bill Slaughter says Lowndes County can’t afford to put agendas and minutes online for the Greater Lowndes Planning Commission? And if a county can require a solar farm to follow stormwater management and numerous other regulations, why can’t a county require a natural gas pipeline to follow local regulations? It can, if its elected officials actually stand up for their citizens. And why can Nash County, quite a bit north of Lowndes County, install solar farm after solar farm while there are none in Lowndes County?

The Nash County online documents also include the details of what the various boards were considering, such as in the Agenda and Minutes of the Nash County Planning Board 21 October 2013, which include this item:

  1. Conditional Use Permit Request CU-130901 (Previously Tabled Item).
    Made by Chris Killenberg With Community Energy Solar on Behalf of Castalia Solar LLC to Develop a Solar Farm on an Approximately 22.91 Acre Portion of Two Tracts Located on the West Side of N NC Highway 58 and South of NC Highway 56 in the A1 Agricultural Zoning District.

And not just the agenda item, also extended discussion in the meeting, including: Continue reading →

Utilities can’t take the solar heat

Utilities are trying increasingly desperate tactics in their losing battle against distributed rooftop solar power. It’s time for them to get out in front and lead instead.

Clare Foran wrote for NationalJournal Are Utilities Wilting From Heat of Solar Competition?

Regulatory battles over solar power payment models played out in several states this year. And as the dust settles, solar providers are claiming victory. Utilities, on the other hand, are trying to reframe the conversation entirely by insisting they aren’t an enemy of solar.

After discussing utlities’ attempts to bash net metering, she notes the Sierra Club hard-won victory over the ALEC solar tax:

Sandy Hill Solar, Elm City, NC

Can’t miss this driving north on I-95: acres of solar panels next to the highway, paying a local farmer for decades.

MacDonald wrote for enerG September/October 2012, Solar picking upsteam in the U.S. South,

The Sandy Cross solar farm is the most recent project completed by O2energies, a mid-sized Charlotte-based solar development firm that has built a reputation for combining sustainable agriculture and sustainable energy production on farms in the southeastern U.S. The company owns and operates several solar farms in North Carolina.

The company’s president, Joel Olsen, notes that agriculture and energy production can complement each other. Solar farms have a low profile, are noiseless, produce no pollution, and consume no water.

Olsen points out an interesting fact: solar farms can often be Continue reading →
