Learn how to cool effectively and efficiently

Guilford Solar's monthly program for December will feature a presentation on effective and efficient cooling, by Michiel VanderSommen. Specifics are as follows:

What: Guilford Solar's December program
When: Saturday, December 13, 10 a.m. to 11:30 a.m.
Where: Barn Kitchen Meeting Room of the Guilford County Agricultural Center, 3309 Burlington Road, Greensboro, NC 27405
Cost: Free

Description:

For our December program, Michiel VanderSommen will offer a presentation on "Cooling Effectively and Efficiently." Cooling is a particular challenge here in the Piedmont Triad, as we lack useful wind and are saddled with high humidity. Michiel will concentrate on "passive" cooling but will also discuss the more conventional AC (and the maintenance thereof). He will consider the purpose of shrubbery, discuss such concepts as albedo and heat island, and cover the importance of shading, among other things. Because the topic of insulation (which is clearly relevant to cooling) was covered in our November Guilford Solar meeting, it will not be emphasized here.

Three Major Solar Projects for NC

After years of false starts, large-scale solar power is scheduled to come to North Carolina.

Progress Energy is planning a 1.2-megawatt solar farm on 10 acres in Wilmington, to be built at the same complex as the utility's coal-burning power plants, it announced Friday. The solar farm could generate enough power for about 800 homes on sunny days. It is expected to start generating electricity this year. The Progress Energy solar project will be developed, owned and operated by SunEdison, a national solar developer in Maryland. SunEdison will sell the power it generates to Progress, which will then redistribute the electricity to its customers.

SunEdison announced two other solar projects in the state this year:
* a 1-megawatt project on the Cary campus of software developer SAS, which will sell power to Progress.
* a 16-megawatt solar farm in Davidson County that will sell power to Duke Energy.

The Davidson County project appears puny compared with the 900-megawatt Shearon Harris nuclear plant in Wake County, but it's colossal by solar standards. The nation's largest solar project is about 14 megawatts, at Nellis Air Force Base in Nevada.

North Carolina, a state where solar energy has never been adopted on a large scale, is suddenly developing three significant solar projects. "It's about time," said Stephen Kalland, director of the N.C. Solar Center at N.C. State University. "The technology has been there for some time." The interest in solar in this state is being driven by a 2007 state law requiring that power companies tap renewable resources. The law may elevate North Carolina to a national solar hot spot; utilities must develop an estimated 300 megawatts of solar power by 2021 to meet the renewables standard, Kalland said.

Progress Energy, Duke Energy and municipal power agencies are all reviewing proposals from developers of renewable power, including solar, wind and biomass resources. Duke plans to develop its own statewide solar power network on about 850 sites, primarily rooftops.

North Carolina's potential for 300 megawatts is likely to look less impressive over time. An 800-megawatt solar proposal is in the works in California. That project would put solar power on the same scale as the behemoths of energy -- nuclear power plants and coal-burning plants. Today, North Carolina has less than a half-megawatt of solar power, mostly rooftop projects on private homes that are subsidized by NC GreenPower, a Raleigh nonprofit group that has been supporting solar projects since 2004. NC GreenPower has 167 solar projects; many are so small that they don't generate enough power for one home.

The high cost of silicon wafers and rising demand for silicon by the computer chip industry have been major impediments to solar development. Generating solar energy once cost about five times as much as building conventional power plants, putting solar out of reach unless it was heavily subsidized. The cost of nuclear power is soaring, but solar power is still about twice as costly as nuclear, Kalland said.

North Carolina regulation of utilities presents another obstacle to solar. Solar developers such as SunEdison are not allowed to sell electricity to businesses or homes. They can only sell to power companies, which in the past were unwilling to invest in solar energy, because it was expensive. Solar systems produce emissions-free electricity without greenhouse gases or radioactive nuclear waste. The downside is that solar power operates only about 20 percent of the time, compared with nuclear and coal plants that run around the clock.

The financial terms of the SunEdison contracts are confidential, and utility officials declined to discuss how much they are paying for solar. Progress spokesman Mike Hughes said other factors necessary for solar development include negotiating for land, and often, providing connections to transmission lines. "It's one of the technologies where price has come down and likely will continue to come down," Hughes said.

Peak Oil arrives in Greensboro

Here are two items of importance regarding peak oil:

1. The News & Record is publishing a series on peak oil, and it will be hitting the stands soon. Morgan Glover, the reporter who authored the series, has been working for months on this. She is extremely knowledgeable about the topic, and I am expecting this to be an excellent series. The first installment is to be published on Sunday, June 29, the second on Wednesday, July 2, and the third installment is to appear on Saturday, July 5. Don't miss it!

2. Guilford Solar will be offering a 2-hour special on peak oil as its July monthly program. The specifics are as follows:
What: Guilford Solar July Program: "Peak Oil -- Theory and Evidence"
Where: Kathleen Clay Edwards Family Branch Library, 1420 Price Park Road, Greensboro
When: Saturday, July 12, 10 AM -- 12 Noon
Cost: Free
Description: Transportation is the lifeline of our current global and US economies. Over 95% of our transportation is dependent upon the refined products of oil -- gasoline, diesel, jet fuel, and bunker fuel. As the price of oil sets new records weekly, the question naturally arises: Why is this happening? One increasingly common explanation is that the rate of production worldwide of cheap, high-quality oil has peaked or will do so in the near future. This is the "peak oil" hypothesis. Guilford Solar's July program will explain the meaning of peak oil and will examine the evidence that supports it. The presenter is Peter Kauber, who has researched the topic over the past four years. Kauber was employed by Marathon Oil Company during the 1979-1981 "oil crisis" and thus brings a historical and industry perspective to the discussion.

Note: Though I have not yet seen the contents of the News & Record peak oil series, I am expecting to reference some of its material in my own presentation on July 12. This will be my attempt to provide integration between what Morgan presents in her series and what I am already planning to present. Therefore, if you are expecting to attend the Guilford Solar program, reading the N&R series should function as a useful introduction to what I will be presenting on July 12.

Have a good read, and I hope to see you at the Library on July 12.

Duke to support residential solar??

Here is an article from earth2tech (5-12-2008):

The debate between massive solar thermal plants and distributed roof top solar projects continues to get more interesting every day. Duke Energy’s CEO Jim Rogers says the utility will build and operate solar power, and plans to invest $100 million in solar rooftops, both commercial and residential, according to the Charlotte Business Journal reports. Duke still needs to get permission from the North Carolina Utilities Commission.

This is part of an emerging trend of utilities throwing their considerable assets behind solar installations as a way to own solar power generation. Utilities are feeling pressure from their home states’ renewable portfolio standards to incorporate more renewable energy sources. (North Carolina has a renewable portfolio standard that goes into effect in 2012 and will require utilities to generate 12.5 percent of their energy from renewable sources by 2021.) Utilities are able to leverage their balance sheets to get capital at far better rates than small startups, allowing them to invest hundreds of millions of dollars in solar development.

Southern California Edison announced plans in March to invest $875 million in 250 megawatts of solar covering some 2 square miles of rooftops. PG&E’s CEO Peter Darbee recently told us that the company is in discussions to build and own its own solar power plants, but that there are some barriers for regulated utilities to cash in on the investment tax credits for solar. (Also check out our video interview with Darbee.)

Duke’s plan to spend $100 million on its own solar generation, is good news for an energy company that generates 70 percent of its power from coal, making it the third-largest consumer of coal in the United States. To his credit Rogers has been an advocate of backing renewable energy, and just last week called for “a small fee on every kilowatt-hour of electricity sold in the U.S.,” which he says would raise $11 billion annually for renewable energy research and development.

PG&E’s Darbee is calling for a change in policy whereby utilities could benefit from the investment tax credit (ITC) to build solar plants. Letting utilities tap into the ITC could be one of the best ways to connect considerable capital with solar power construction.

So....... Solar!

Here is a press release from Duke Energy:

Duke Energy Announces Deal to Harness the Power of the Sun May 21, 2008 CHARLOTTE, N.C. - Duke Energy Carolinas today announced it will purchase the entire electricity output of the nation's largest photovoltaic solar farm to be built in Davidson County, N.C., north of Charlotte.

Under agreements signed with SunEdison, customers of Duke Energy Carolinas are expected to receive more than 16 megawatts of power from the solar farm beginning no later than Dec. 31, 2010. The agreements run for 20 years.

“We said we wanted to lead the way in the development of more renewable energy and we meant it,” said Keith Trent, group executive and chief strategy, policy and regulatory officer. “Today’s agreements, coupled with the other significant initiatives across our company, clearly demonstrate that renewable energy has an important place in our power generation portfolio.”
The SunEdison agreements are a result of a request for proposals, or RFP, that Duke Energy issued in April 2007. It was the first RFP of its kind in North Carolina and was specifically designed for potential renewable providers.

In addition to purchasing renewable energy from other providers, Duke Energy is advancing plans for its own distributed solar generation program. Distributed generation is energy created close to where it is used, rather than being produced in large power plants and sent to customers over the power grid. The company plans a filing with the North Carolina Utilities Commission in the near future that will seek approval for the program, and the authority to recover its investment. Under the plan, Duke Energy would install and operate distributed solar generation on customer rooftops and other spaces.

Duke Energy is also adding wind power to its generation portfolio. In April 2008, a wind farm in Indiana began supplying 100 megawatts of power to Duke Energy customers. In 2007, Duke Energy Generation Services entered the wind energy business and expects to have its first projects (about 180 megawatts) online later this year. Other wind development projects of more than 3,000 megawatts are planned in eight different western and southwestern states. In 2007, Duke Energy supported the development of the new Renewable and Energy Efficiency Portfolio Standard (REPS) in North Carolina. It requires the utility to satisfy 12.5 percent of its customers’ power needs with renewables or energy efficiency by 2021. Specific solar requirements are implemented in 2010. By 2018, at least two-tenths of one percent of total retail sales must come from solar energy. In Ohio, the company also supported that state’s new advanced energy portfolio standard, which sets a requirement of 12.5 percent of a utility’s sales to be met with renewable energy sources by 2025.

Broader use of renewable energy is part of Duke Energy’s comprehensive plan to create a sustainable energy future for the Carolinas while the company continues to work to reduce its environmental footprint. The plan includes building new power plants; robust energy efficiency programs to reduce demand; and supporting state and federal energy policies that encourage the development of new technology. Together, these initiatives will allow Duke Energy to continue to meet customers’ need for power in an environmentally sound way.

Duke Energy's Carolinas’ operations include nuclear, coal-fired, natural gas and hydroelectric generation. That diverse fuel mix provides nearly 21,000 megawatts of safe, reliable and competitively priced electricity to more than 2.3 million electric customers in a 24,000-square-mile service area of North Carolina and South Carolina.

Duke Energy, one of the largest electric power companies in the United States, supplies and delivers electricity to approximately 4 million U.S. customers in its regulated jurisdictions. The company has approximately 35,000 megawatts of electric generating capacity in the Midwest and the Carolinas, and natural gas distribution services in Ohio and Kentucky. In addition, Duke Energy has more than 4,000 megawatts of electric generation in Latin America, and is a joint-venture partner in a U.S. real estate company. Headquartered in Charlotte, N.C., Duke Energy is a Fortune 500 company traded on the New York Stock Exchange under the symbol DUK. More information about the company is available on the Internet at: http://www.duke-energy.com/?sec=content.

Sun Edison LLC is North America's largest solar energy services provider and operates across a global marketplace. SunEdison provides solar-generated energy at or below current retail rates to a broad and diverse client base of commercial, municipal and utility customers.

Solar power for your home or business

Solar energy is a renewable (“green”) energy that is available and accessible for most people throughout North Carolina, and that can be used for various applications. One important application is the production of electric power for residences or businesses.

The February Guilford Solar program will provide the general public with an overall understanding of electric power production from the sun. Included will be an overview of system components, costs, recent innovations, tax incentives, and power grid inter-connection requirements. Other related issues such as the siting of a solar system and the availability of local manufacturers, vendors, and installers will also be discussed. In addition, the implications of “net-metering” and the “NC GreenPower Agreement” will be examined.

Tom Honey, a local solar power installer with many years of experience and several installed PV systems in the Triad area, will conduct the presentation.

This event, co-sponsored by the Greensboro Public Library, will be held on Saturday, February 9, from 10 – 11:30AM, in the auditorium of the Kathleen Clay Edwards Family Branch Library, 1420 Price Park Road, Greensboro.
