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,

Fracking water

Yet another reason why we should take water into account in any development plan: fracking for shale gas uses huge amounts of water, competing with everything else, maybe even using more than power plants and cities.

Delaware Riverkeeper and Protecting Our Waters wrote for Waterkeeper Alliance today, The Water Footprint of Shale Gas Development,

Recent studies examining potable water supplies on a global scale, the current trends in American water consumption and the causes of depletion of this essential resource are helping us to understand that the footprint of shale gas development expands indefinitely when measured in water….

Of the seven nations where the groundwater footprint is greatest, the U.S. is one of the fastest speeding towards disaster. According to Cynthia Barnett’s Blue Revolution, scientists say the 20th century was the wettest in a thousand years and now drier times are ahead.[3] This means that many of the management schemes we use now—based on 20th C planning—need to be changed to avoid catastrophe. So the 410 billion gallons of water America uses every day will suck the nation dry if we don’t stop over-tapping nearly every river and aquifer.

The biggest U.S. users are power plants and agriculture with private

Wind second only to natural gas in 2011 added capacity

Looks like Southern Company (SO) bet on the wrong horse.

David Danielson wrote for DoE 14 August 2012, A Banner Year for the U.S. Wind Industry,

The report finds total U.S. wind power capacity grew to 47,000 megawatts by the end of 2011 and has since grown to 50,000 megawatts, enough to power 12 million homes annually — as many homes as in the entire state of California. And as wind energy capacity has grown, more and more wind turbines and components like towers, blades, gears, and generators are “Made in America.” Nearly 70 percent of all of the equipment installed at U.S. wind farms last year came from domestic manufacturers, doubling from 35 percent in 2005.

Why should SO worry? Wind only came in second in added capacity. Because of this:

In addition to strong gains in domestic wind manufacturing and capacity, the report finds that as wind technology improves, costs are coming down. Technological innovations are helping make longer and lighter wind turbine blades, while improving turbine performance and increasing the efficiency of power generation. At the same time, wind project capital and maintenance costs have continued to decline.

And wind doesn't even have Moore's Law going for it as much as solar does, plus solar is usable in more areas than wind. Add wind and solar and why do we need much natural gas? (Or any coal or nuclear?)

Where would Georgia Solar Utilities Inc. get enough land for 80 MW solar generation?

Plant Branch in Georgia Where will Georgia Solar Utilities Inc. get the 2,200 acres it says it needs to build 80 MW of solar generation? Well, it’s supposed to be “adjacent to Georgia Power Co’s coal-burning Plant Branch near Milledgeville, Ga.”, so let’s look there.

Plant Branch Location Map A brochure on Plant Branch by Georgia Power (undated, but last date mentioned is 1998, so I’m guessing 1999) says:

Located on 1,900 acres on Lake Sinclair in Putnam County between Eatonton and Milledgeville, Plant Branch was the first million-plus-kilowatt electric generating station to operate on the Georgia Power system. It is named for Harllee Branch Jr., former chairman of the board of Southern Company and president of Georgia Power. Construction on the plant began in 1961, and by the summer of 1969, Coal pouring onto pile four units were in operation. The 1,539,000 kilowatts generated by Plant Branch provides enough electrical power for 342,000 households.

And now Plant Branch will be among the first to close coal-generating units. According to Melissa Stiers for GPB News 12 July 2011, Georgia Power Closing Three Plants,

Two coal fired units at Plant Branch in Milledgeville will close in 2013. That’s a result of federal regulation tightening air pollution controls. The company has said it’s too costly to upgrade those units.

Plant Branch across Lake Sinclair As we know, Georgia Power’s parent The Southern Company claimed it was incompetent to deal with the new EPA regulations even though it had already announced the Plant Branch closures (amounting to about 770 MW), and later SO announced 4,000 MW of coal plant closures.

While the various news stories keep saying Plant Branch is in Milledgeville, actually, it’s on the other side of Lake Sinclair, closer to Eatonville, Plant Branch site in Putnam County qpublic map and in Putnam County. A quick glance at the Putnam County Tax Assessor database maps shows that the land parcel containing Plant Branch is 913.87 acres, much of which isn’t actually used by the plant. And Georgia Power owns a total of more than 3,000 acres adjacent to that site. So I’m guessing the 2,200 acres figure is simply around 3,100 total Georgia Power acres minus 913 acres for the present Plant Branch site.

Company to build 90 MW solar and become a utility

What to do if you can’t interest Georgia Power in building solar? Do it yourself, and do enough so you can be a utility yourself. That’s the loophole in the 1973 Electric Territorial Act that FPL and JEA use to burn coal at Plant Scherer in Georgia and export the power to Florida. Now Georgia Solar Utilities Inc. is using the loophole for a better purpose: building almost twice as much solar generation as Georgia Power’s meager 50 MW.

Georgia Solar Utilities Dave Williams wrote for the Atlanta Business Chronicle yesterday New Georgia utility pitches solar plant: A new utility is planning to build a $320 million solar power plant on 2,200 acres adjacent to Georgia Power Co’s coal-burning Plant Branch near Milledgeville, Ga.

Georgia Solar Utilities Inc. initially approached Georgia Power, a unit of Southern Co. (NYSE: SO), with a proposal to build the plant and sell it to Georgia Power through a power-purchasing agreement.

Georgia Power is retiring two coal-fired units at Plant Branch, part of a move to reduce the Atlanta-based utility’s reliance on coal.

But when Georgia Power officials declined to take part in the project last May, Georgia Solar Utilities executives decided to build the plant on their own and operate it as a new utility independent of Georgia Power.

Once cost prohibitive, solar energy has become competitive with fossil fuels because of the rising costs of coal and tighter government regulation of coal emissions, said Robert Green, founder of Georgia Solar Utilities.

“When you don’t have to buy coal or worry about environmental hangovers, it overwhelms the costs of fossil fuels, Green said Thursday after presenting the proposal to the Georgia Public Service Commission’s Energy Committee.

Some say the PSC can’t approve such a utility because of that 1973 law. I suspect that if they don’t approve this proposal, the next one will be even harder to turn down, and the next one, as they become even more competitive.

How competitive?

Cleaner energy creates jobs in Iowa

In Iowa they didn’t whine about cleaner power regulations like Southern Company did, they went ahead and got on with it without dragging their feet for months or years. Simply complying with the new EPA regulations has created jobs for Iowans.

Matt Kasper wrote for ThinkProgress today, Pollution Control Retrofit Creates 400 Jobs In Iowa: Project Is A ‘Win-Win For Iowa’s Economy And Environment’

Alliant Energy in Iowa is celebrating an emission-reduction technology that will help a power plant meet new standards — creating 400 jobs in the process. One recent study found that “EPA’s two new air quality rules create 1.5 million jobs.”….

The Ottumwa Courier reported:

“The OGS [Ottumwa Generating Station] project is a win-win for Iowa’s economy and environment,” said Pat Kampling, president and CEO of Alliant Energy. “The project at OGS will create approximately 400 good-paying construction jobs for Iowa’s working families and foster future economic growth while making Iowa’s air cleaner.”

Better for public health, better for less climate change, and better the economy: more jobs for Iowans.

ALEC, private prisons, fossil fuels, and charter schools

It’s good to see someone trying a coordinated strategy for something good in multiple states, as Our Children’s Trust is doing for air as a public trust. We already knew going to multiple states at once works, because ALEC, the American Legislative Exchange, gets reactionary results that way.

How does ALEC do it? By

So once again, it’s refreshing to see somebody successfully try multiple states for something worthwhile!

The above ALEC projects are just some I’ve run across while researching local topics. It often seems as if every rock I turn over has the ALEC millipede scurrying around under it. Far more about ALEC is available through ALEC Exposed.

ALEC Exposed has a list of companies that have dumped ALEC recently. Georgia Power’s parent The Southern Company and UPS are still not on that list. You can help. Let them know you want them to dump ALEC!

New research shows Natural Gas far more dangerous for climate stability —Seth Gunning

Received yesterday on U.S. CO2 emissions lowest in 20 years: that's good and bad: natural gas is methane, after all. -jsq

Yet another comprehensive article. I might also add that one of the major down-falls (if not the most significant) of large-scale conversions to natural gas is the resources lifecycle methane emissions.

As your readers likely know, Methane is about twenty times as 'potent' a greenhouse gas as Carbon Dioxide. That is to say, it is far more efficient at trapping heat then Co2. So, less methane has a far greater impact on climate disruption then more Co2.

Natural Gas, from the point of combustion, releases about half the amount of Co2 released from burning coal, and about 30% of what's released in burning oil. To keep the benefits of reduced Co2 levels when switching from coal to natural gas, natural gas wells and transport lines must leak less then 2% of methane into the atmosphere. Recent research from Cornell is showing that Fracking wells are regularly releasing more then 4%, and often as much as 8% —far exceeding the 2% threshold— and thus making Natural Gas a far more dangerous resource for climate stability.

U.S. CO2 emissions lowest in 20 years: that’s good and bad

The good news: because utilities such as Southern Company are switching away from coal U.S. emissions of CO2 are the lowest they’ve been in 20 years. The bad news: they’re switching to natural gas, which not only still emits carbon dioxide, it pollutes groundwater through fracking, requires a lot of groundwater to do the fracking in the first place, and then uses more groundwater for cooling. But the further good news is cheaper energy sources drive out expensive ones, and wind and solar are already cheaper than nuclear and coal, and solar is already cheaper than natural gas. Oh, and solar and wind emit no CO2.

Kevin Begos write for AP yesterday, AP IMPACT: CO2 emissions in US drop to 20-year low

“There’s a very clear lesson here. What it shows is that if you make a cleaner energy source cheaper, you will displace dirtier sources,” said Roger Pielke Jr., a climate expert at the University of Colorado.

While conservation efforts, the lagging economy and greater use of renewable energy are factors in the CO2 decline, the drop-off is due mainly to low-priced natural gas, the agency said.

A frenzy of shale gas drilling in the Northeast’s Marcellus Shale and in Texas, Arkansas and Louisiana has caused the wholesale price of natural gas to plummet from $7 or $8 per unit to about $3 over the past four years, making it cheaper to burn than coal for a given amount of energy produced. As a result, utilities are relying more than ever on gas-fired generating plants.

Both government and industry experts said the biggest surprise is how quickly the electric industry turned away from coal. In 2005, coal was used to produce about half of all the electricity generated in the U.S. The Energy Information Agency said that fell to 34 percent in March, the lowest level since it began keeping records nearly 40 years ago.

And that’s why Southern Company (SO) turned towards natural gas: it’s cheaper! SO still prefers nuclear and coal before gas, as SO CEO Thomas A. Fanning keeps reminding us. But even SO couldn’t ignore “the revolution in shale gas”, which is cheaper prices through fracking. Solar PV costs dropped 50% last year alone. How long can SO ignore that?

“Natural gas is not a long-term solution to the CO2 problem,” Pielke warned….

Toxic air in Georgia —NRDC

Georgia's air: not quite as bad as Florida's.

WTXL wrote Thursday, Florida and Georgia ranked high for toxicity exposure,

According to an analysis released by the Natural Resources Defense Council (NRDC), Florida is the 6th worst state in the nation when it comes to exposing residents to toxic air pollution from coal-fired power plants.

Florida's air would rate even worse if Florida Power and Light had to burn coal in Florida instead of at Plant Scherer near Macon to generate power for Florida. Instead, FPL dirties Georgia's air for Florida's benefit.

Georgia is ninth worst on the NRDC's Toxic 20 list, in “Toxic Power: How Power Plants Contaminate Our Air and States”. Here's NRDC's press release.
