Aqueous Hybrid Ion (AHI) battery

Here’s a new battery technology that might be good for evening out solar power production: the Aqueous Hybrid Ion (AHI) battery. Some such storage method will eventually become good enough to do away with most of the arguments about solar power fluctuating with time of day and weather. Meanwhile, getting on with a smart grid would go ahead and do that.

When we got our new solar panels we did not buy batteries with them, because enough batteries for 12 kilowatts of solar would have been quite expensive. Our old panels do have batteries backing up their 3 kilowatts, so when the grid is out we still have that much power, which can keep us up (refrigerator, lights, computers, Internet) for 10 hours even at night, and longer if the sun is shining. We’re waiting for better electricity storage methods. Maybe AHI is it, or maybe something else will be.

Somebody thinks AHI is promising. PR dated 19 June 2012: Horizon Technology Finance Leads $15 Million Venture Loan Facility for Aquion Energy, Continue reading →

Profits per Market Cap in the Forbes 2000: solar and wind still win

We saw that two out of three of the most profitable electric utilities in the world emphasize solar and wind energy: ENEL of Italy and Iberdrola of Spain, both of which operate in multiple countries, including Iberdrola claiming second most wind power in the U.S. Well, maybe those companies are small, so their profits are a fluke. Nope. We get similar results for profits divided by market cap:

ENEL of Italy is still number 1, with no nuclear and a lot of solar and wind energy. Iberdrola is #4 in profits/market instead of #3 in profits alone. However, Electricité de France (EDF) is #7 instead of #2, and Exelon is #9 instead of #4. Number 2 is Energias de Portugal (EDP), which is heavily into wind power including owning Horizon Wind Energy LLC:

Southern Company deploying solar in Nevada and New Mexico (but not Georgia)

Southern Company (SO) is deploying solar power in two southwestern states. Meanwhile, in Georgia, the 1973 Territoriality Act continues to impede others deploying solar while SO and Georgia Power waste our money on a nuclear boondoggle.

PR from Southern Company and Turner Renewable Energy, 29 June 2012, Southern Company and Ted Turner Acquire Second Solar Photovoltaic Power Project

Southern Company (NYSE: SO) Chairman, President and CEO Thomas A. Fanning and Turner Renewable Energy founder Ted Turner today announced that the companies have acquired and will bring on line a 20 megawatt solar photovoltaic power plant in Nevada.

The Nevada plant is the Apex Solar Project, and earlier they did the Cimarron Solar Facility in New Mexico.

“Southern Company is proud to play a leadership role in renewable generation as we deliver clean, safe, reliable and affordable energy to our customers,” said Fanning. “Our all-arrows-in-the-quiver approach calls for 21st century coal, nuclear, natural gas, renewables and energy efficiency in a diverse fuel mix necessary to meeting growing consumer demand and furthering America’s energy independence.”

Maybe it’s just an oversight that SO CEO Fanning listed coal first Continue reading →

Nuclear and coal burning water: solar doesn’t

Solar power is the smart thing to do for jobs, energy independence, and profit. It’s also what we need to do to save water.

Julia Pyper and ClimateWire wrote for Scientific American 29 June 2012, Electricity Generation ‘Burning’ Rivers of Drought-Scorched Southeast: A new report reckons the water cost of electricity generation

Power plants are guzzling water across the United States and increasing the risk of blackouts in the Southeast, where the precious resource is drying up.

“Burning Our Rivers,” a new report by the River Network, found that it takes about 40,000 gallons of water to meet the average American household’s energy needs, which is five times more than the amount of water used directly in that home….

Table 3. Total Water Footprint of a Kilowatt-hour
(Gallons per kWh)
2009 U.S. Electric Grid
(National weighted average)
Hydroelectric 29.920
Coal 7.143
Natural Gas 1.512
Nuclear 2.995
Geothermal 0.002
Solar 0.002
Wind 0.001
Total 41.575

In the Southeast, which has been battling a drought for more than a year, the impact of power plants is especially worrisome and could lead to brownouts and blackouts throughout the summer and beyond.

“The conflicts between energy and water needs are ones we’ve seen before … and will only worsen as the frequency of drought increases and water temperatures rise driven in part by climate change,” said Ulla Reeves, regional program director at the Southern Alliance for Clean Energy.

The report’s number 1 recommendation:

1. As a nation, we should focus on renewable energy sources and low water technologies.

Why?

It’s only going to get hotter: time for solar power

Looks like the heat wave is going to continue for a while, according to NOAA’s maximum heat index forecasts. Reuters wrote today,

A heat wave baking the eastern United States in record temperatures is set to continue on Sunday after deadly storms killed at least 12 people, downed power lines from Indiana to Maryland and left more than 3 million customers without power….

Utilities in Ohio, Virginia and Maryland described damage to their power grids as catastrophic.

Record Georgia temperatures above 100 degrees

Driving north Friday, the temperatures kept getting hotter. John C. Griffin recorded these temperature signs, used here by permission. Friday 29 June 2012:

I can attest it was still over 100 in Macon after dark Friday.

And it only got worse Saturday 30 June 2012:

Millions without power due to no smart grid

We know the answer to this! Top story on CNN.com today: Millions without power as storms pound U.S. following record-setting heat

Nearly 4 million homes lost power early Saturday across the Midwest as a fierce line of thunderstorms and winds pounded the region after record-setting temperatures.

The storms moved east from Indiana through Ohio and into West Virginia, according to utility companies. Virginia was hit with power outages to more than 1 million homes.

The outages come as tens of millions in the central and eastern United States are battling a sweltering summer.

Thirty years ago the Internet demonstrated distribution and decentralization is the way to avoid widespread outages. That's what a smart grid would give us. I can say by experience that if many of those homes and businesses had solar panels with batteries, they could weather 10 hours or more of no grid power with no problem. My solar panels and batteries have done that for my house for years. Yours could too, and you could be selling excess power to people and businesses that don't have panels, if Georgia Power would let us change state law to let us.

And hey, with wind power, in a storm you'd have more power!

Temperatures Friday soared past 100 degrees Fahrenheit from Kansas to Washington, with scorching conditions expected to continue through the weekend and beyond.

It was 107 degrees in Macon, Georgia yesterday at 7:30 PM. So what's Georgia Power doing about solar power in Macon? Still studying it, according to Josephine Bennett in NPR a year ago:

Georgia Power's Carol Boatright says for 18 months researchers will collect data and then ask the following questions.

How about this question, Georgia Power and the Southern Company and Oglethorpe Power and all the EMCs: Will you wait until Georgia is without power until you deploy solar power, or get out of the way so we can do it ourselves?

Electric Utility Profits in the Forbes Global 2000 from 2006 through 2012

Which are the most and least consistently profitable electric utilities in the world? Hint: the biggest losers all lost on nukes. But the biggest winners may surprise you.

Following up on Southern Company CEO Thomas A. Fanning’s brag that “We are a great, big company from an energy production standpoint,” I looked in the Forbes Global 2000 to see which are the biggest electricities in the world. Indeed, Southern Company (SO) is the biggest in the U.S. and number 6 in the world for 2012. But what about the rest, and what about previous years? Here’s a graph of profits for the top 40 electric utilities from 2006 through 2012. SO is the blue line muddling along in the middle:

What’s that dark red line dropping way below the rest? Tokyo Electric Power (TEPCO), owner of the Fukushima nuclear plants. And the red line starting at the top and ending up near the bottom? E.ON, the company that owns most of Germany’s nuclear plants, as Germany shifts away from nuclear energy, after Cheronobyl and now Fukushima. The blue line that ends up as low as E.ON? Korea Electric Power (KEP), also an owner of nuclear plants. All the big losers are nuke owners.

What about the winners? The light green line ending up second by profits is Electricité de France (EDF), also an owner of nuclear plants, but one which has not yet had a major accident.

But what’s that purple line that starts near the top and ends up at the top?

Strategies for Lowndes County? —John S. Quarterman

My op-ed in the VDT today. -jsq

Our high schools and college graduates mostly have to go somewhere else, because jobs here are few and many of them don’t pay enough for a decent living. Should we not care enough about our families and our community to come up with strategies that grow existing businesses and attract new ones that will employ local people?

We need discussions and strategies that involve the whole community, going beyond just the usual planning professionals, to include all groups and individuals with information or opinions, whether they got here generations ago or last week: for fairness and for freedom.

Sometimes we see local strategy. Winn Roberson organized Drive Away CCA. Ashley Paulk verified there was no business case for a biomass plant in Lowndes County after many people successfully opposed it. School “unification” opponents, out-financed 10 to 1, still defeated that referendum 4 to 1.

How do we go beyond opposing things and move on to sustainable strategies that build clean industry?

The Industrial Authority focus group meeting I attended Wednesday was refreshing, because their consultants asked the opinions of people some of whom previously had to picket outside. The previous day, VLCIA Chairman Roy Copeland said this strategic planning process was a long time coming. I agree, and while nobody can say what will come of it at this point, I hope it does produce a real Economic Development Strategy.

Dublin ahead of us again: solar street lights

Dublin, Georgia already got MAGE Solar and car part manufacturer Erdrich Umformtechnik. Now Dublin is ahead of us again, with solar street lights.

Austin Lewis wrote for 13WMAZ yesterday, Dublin Sets Up Solar Street Lights,

Dublin has started putting up Solar street lights on South Jefferson near the city's downtown. This project got federal funding from the federal government administered by the Georgia's Department of Transportation.

And grant supported! If anybody around here had applied, maybe we would have gotten such a grant.

Instead, it's another first for Dublin:

"This is the first transportation corridor that has solar lighting in the state of Georgia so it's just very exciting for us, first to have a solar industry in Dublin, now to have the first state roadway lit by solar lighting," said Tim Lake, of T. Lake Environmental Design.

Bragging rights and practical, too:

Lake said the cost of these street lights is about $11,000 and that the standard street lights cost just over $7,600. But the typical street light have other costs like a leasing fee and monthly energy costs that go to the electric company.

He said because the solar street lights are powered by the sun, they will end up saving taxpayers about $500 dollars a month or $15 per street lamp.

"The first is return on investment happens very quickly, 3.7 months for the city to get a return on investment on these lamps," said Lake.

All that plus this:

The solar panels were also made in Dublin by MAGE Solar. Lake said this was a truly collaborative project.

Collaboration. Maybe our Industrial Authority should try it.
