Solar Energy Can't do it alone- What about Nuclear Energy?

Proponents of alternate energy generation generally support “green” technologies like solar and wind. These same green advocates often shun nuclear energy and point to a long list of dangers inherent in that technology. Yet blind support of solar power is like demanding that you use rubber bands to power you car. For solar to work, we'll need to make big adjustments in our homes and lifestyles.

Solar powered electricity generation made up less than 1% of the generation mix in 20007. According to the Solar Electric Power Association, there were “473MW [megawatts] of grid-connected photovoltaics installed throughout the entirety of the U.S. as of the end of 2007”. Assuming that this 473 MW of grid tied resource got an average of 6 hours of sun each day, they would produce about 1,035,870 Megawatt hours of electricity in a year.

This is not merely a numbers game. We won’t meet our energy needs by doubling or tripling or even quadrupling our photovoltaic generation.

Nuclear electricity generation produced record levels in 2007. Energy Information Administration data show that nuclear generation climbed slightly this May. “Nuclear output rose 13 percent in May 2008 compared with the preceding month. Even with the increase, generation was slightly below May 2007 (less than half a percent difference). Cumulative generation for the first five months of 2008 is slightly over one percent lower than in the record year of 2007.”

In 2007, 806,486,978 Megawatt Hours of electricity was produced by nuclear reactors in the USA. Thirty two states produce a portion of their electricity from nuclear power and 20% of all electricity produced in the USA came from nuclear reactor generation in 2007.

The challenge here when talking about ways to solve climate change and reduce green house gas emissions tied to electric energy production is the big gap between what the public seems to want for power generation -clean power- versus what the public wants in terms of the growing electricity demand.

One typical residential solar photovoltaic setup with twelve 100 watt PV collectors in a sunny part of the USA might be capable of producing 216 kilowatt hours per month or 2.5 Megawatt hours per year.

The South Texas Project 1 nuclear facility produced almost 12 million megawatt hours in 2007. The smallest nuclear generation facility, Point Beach 1 in Wisconsin produced almost 4 million megawatt hours. It would take over 18,000 homes running 1.2 KW photovoltaic systems in a sunny climate to come anywhere close to the generation output of the smallest nuclear facility.

Let’s face it folks. If we want to maintain our current standard of living it will take more than solar power to run the nation. Actually, it will take advancements in every electricity generation sector plus a lot of conservation success to keep up with projected electricity demand.

William Tucker offers his perspective for going nuclear in his interesting The Case for Terrestrial (a.k.a. Nuclear) Energy. You may not want to hear it, but you really should try to understand all sides in our great energy debate.

Take Action to Support Distributed Renewable Energy Generation

So, you want to install a solar photovoltaic system on your roof and join those taking action to reverse climate change. You want to be part of the solution to the growing gap between energy demand and new power plant construction by installing distributed alternate energy generation. You’ve consulted your Special 30th Anniversary Edition of the Real Goods Solar Living Source Book, trimmed your home’s energy demand as much as you can without freezing in the dark and you are ready to order your equipment.

Wait! Have you contacted your local utility?

Almost every utility in the nation has some type of policy or regulation that could impact your ability to generate your own power from your own alternate energy system. Utility policies are a function of State regulations and individual utility company choices. Before you dump that list of PV parts into your checkout basket, contact your utility to make sure you can do what you want to do without being surprised by extra fees, technical restrictions or a hostile utility engineer that doesn’t get what you are trying to do.

The Network for New Energy Choices grades States on net-metering and interconnection laws and gives them an “A” through “F” score on how well they assist consumers with installing alternate energy distributed generation systems. The grades are based on a comparison with recommended regulations featured in the model regulations from the Interstate Renewable Energy Council.

Here are the results from the Network for New Energy Choices report.

Net Metering Grades
A IREC Model , New Jersey, Colorado, Pennsylvania, Maryland, California.
B Oregon, Delaware, Iowa, Nevada, Connecticut, Ohio, New Mexico.
C Arkansas, New Hampshire, Rhode Island, Hawaii, Maine, Louisiana, Virginia, North Dakota, Minnesota, Massachusetts, Montana, Vermont, Missouri.
D Washington, New York, Texas, Kentucky, Michigan, Wyoming, Oklahoma, Indiana, West Virginia.
F Utah, D.C., Georgia, North Carolina, Wisconsin.

Interconnection Grades
A IREC Model.
B New Jersey, Arizona.
C California, Ohio, Texas, New York, Colorado, Oregon* , Massachusetts, Georgia, New Mexico* , Vermont, Minnesota.
D Rhode Island, Wisconsin, West Virginia, Arkansas, New Hampshire, Virginia, Iowa, Maryland*, Montana, Michigan, Indiana, Pennsylvania, Connecticut.
F North Carolina, D.C., Wyoming, Louisiana, Delaware, Hawaii, Utah, Washington, Missouri.

The Network for New Energy Choices offers these definitions to explain the difference between interconnection and net-metering and their report offers more details showing what makes a good regulation.

Interconnection – the technical rules for customers to “plug in” to the grid.
Net Metering – the billing arrangement by which customers realize savings from their systems, here 1-kWh generated by the customer has the exact same value as 1-kWh consumed by the customer.

States scoring an A or B are obviously trying to allow distributed alternate energy generators to start-up in their states. States scoring a C are pretending that they care about distributed alternate energy generators. And, States scoring a D or F obviously aren’t interested in having distributed alternative energy play any roll in meeting their electricity demands. The interesting thing is that states scoring A’s are finding spin-off results that improve their economies, reduce costs for customers, and reap financial benefits for their utilities. States scoring D’s and F’s are telling manufacturing industries, businesses and citizens to forget about making any money in the new economy where green businesses are growing new jobs and creating new business opportunities.

The killer in all of this is that a comparison of the top ten states by non-farm employees working in the manufacturing industry are in many cases, the same states that score the lowest on net-metering and interconnection support.

Rank. State – Net-metering Grade/ Interconnection Grade
1. Indiana - D/D
2. Wisconsin - F/D
3. Arkansas - C/D
4. Iowa - B/D
5. Mississippi- no grade/no grade
6. Alabama – no grade/no grade
7. Michigan - D/D
8. Ohio - B/C
9. Tennesse- no grade/no grade
10.Kentucky- D/no grade

So, the states potentially best equipped to make and supply distributed generation equipment and reap the corresponding economic benefits are shooting themselves in the foot when it comes to alternate energy development.

If you live in a State scoring anything less than a B, it’s time to take action. In less time than it took to read this, you can email your state representatives. Tell them you support distributed alternate energy and you think it’s time that they woke up and supported it too. Tell them you’re tired of being a C student- or worse, and you want to get A’s the next time the Network for New Energy Choices scores your State.

To find more details about your utility or your State and how they treat distributed alternate energy generation, visit the Database of State Incentives for Renewables & efficiency (DSIRE) web site and see how they stack up.

Getting to the Dream- Reliable Distributed Renewable Energy Generation

In order to move the idea of small scale renewable energy forward for the every-day home owner in a way that makes a resource contribution to utilities, three things need to happen.

First there needs to be willing homeowners wanting to install distributed generation equipment like wind, solar or biomass generation on their homes. As part of this concept they also need to be interconnected to the grid to make the output of their generators or excess kWh, available to the grid.

Next there needs to be effective, clear and fair state regulations that define net-metering and interconnection requirements. These regulations must not penalize homeowners who want to be distributed system generators or place unfair burdens on compliance.

And finally there have to be utilities willing to adopt and implement programs for those customers or willing homeowners.

To make small scale renewable energy more than just a pipe dream, communities, utilities, state regulators and the nation need to move forward equally on all three fronts.

Willing Homeowners
So far, few homeowners have elected to install renewable energy equipment on their own. Most residential installations nationwide have taken advantage of state or local utility incentives that help homeowners cover some of the estimated $15,000 -25,000 installation and interconnections expenses.

States leading the way in this area like New Jersey and Colorado are struggling with ways to provide incentives without raising rates for all electric rate payers. In addition to the issue of incentives and rebates, the issue of homeowner education is a big issue. Too many homeowners have unrealistic expectations about the amount of money to be made selling excess power back to utilities even in areas with strong utility support for these systems.

These homeowners not only need to be willing to install the equipment on their homes but they need to be willing to monitor their systems and reassure their local utility that they won’t become a danger to themselves, their neighbors or the electric grid itself. A great source of practical self education information is available at Real Goods . They sell a book called the Solar Living Source Book that really is as they claim “the bible on renewable energy”. You can’t be serious about alternative energy and green power if you don’t have one on your book shelf. I have several versions and each new addition has great tips on getting the rubber to meet the road – so to speak.

Supportive State Regulations
In many states with willing and well educated homeowners you may face a list of regulatory hurdles that are more designed to protect myopic utilities, coal producers and the status quo then they are likely to support the installation of interconnected distributed generation. The two key areas of regulatory support are in net-metering regulations and interconnection requirements.

Onerous insurance or safety disconnect requirements can unnecessarily stifle willing homeowners before they even begin buying equipment. Some states however, like New Jersey, Colorado and Pennsylvania are working out these details in a way that protects public safety, assures utilities of safe interconnection and maintenance practices and supports small scale renewable distributed generation. The Network for New Energy Choices provides up to date analysis and reporting on statewide net-metering and interconnection rules. See their report Freeing the Grid: 2007 Edition.

“As of September 2007, thirty-nine states had adopted statewide programs that established rules for compensating consumers who own grid-tied renewable-energy systems. These programs award owners of small, grid-tied renewables the same savings as one would expect from conserving energy on-site.” – Freeing the Grid; Report No. 02-07 November 2007

Progressive Uilities
Utilities have a long history of making excuses for not supporting net-metering or distributed generation connections to the grid, yet for those utilities that have seen the light, customers are helping to meet the growing need for electricity in a way that actually saves utilities money in reduced infrastructure, improved reliability and deferred generation and transmission improvements . One of the leaders in small system residential solar development is the Sacramento Municipal Utility District (SMUD). “SMUD offers an incentive of $2.50 per watt, based on system performance (orientation, array, tilt and shade). The incentive will be paid to the approved PV contractor and should be reflected in the contractor's bid to the customer.”

What is the incentive for utilities to support distributed renewable energy generation? In the long run it will be survival, but in the short run its just money and reliability. In my last post I referred to the North American Reliability Corporation’s Long Term Reliability Assessment conclusions. They discuss electric power shortages in as little as two years. No matter which source you consult, everyone agrees that even with major conservation efforts, there will be a shortage of power. By promoting distributed generation, utilities add resources without the expense of generation and transmission.

Without the three pronged dedication of homeowners willing to dig into their own pockets, State regulator’s supporting reasonable enabling legislation and local utility support and cooperation, the green power revolution will choke on unfulfilled expectations. There are positive signs that all three key actors have learned from past mistake and are working toward a more supportive and measured approach to small scale distributed generation.

The recent Coop America Utility Solar Assessment (USA) Study summary says, “For the first time in history, a confluence of forces is coming together — solar technology developments, conventional energy price increases, aging transmission and distribution infrastructure, climate concerns, security issues, and others — that bring the dramatic worldwide growth of solar increasingly to center stage. In this rapidly changing energy landscape, the 10 percent goal is truly within reach.”

Next week I’ll go into more detail about utility company attitudes towards interconnection requirements and net-metering.

Hey. My hit counter says someone is reading this. What do you think ? Post a comment. If you have a question about energy conservation or renewable energy ask me, I'll try to find objective answers.

What will you do when your area runs out of electricity? - Preparing for Future Electricity Demands

Ignoring the title question is like an ostrich hiding its head in the sand when attacked by wild dogs. Guess which part of the anatomy gets bitten first? So it could be with us, if we all ignore the facts when it comes to getting electricity to our homes and businesses.

Electricity users throughout the United States and Canada are being ostriches unless they actively ask their elected Representatives to deal with the question, “how can we power the future without destroying the planet or making electricity a luxury few can afford”.

“Summer peak demand in the U.S. is forecast to increase over 135,000 MW or 17.7 percent in the next ten years with committed resources projected to increase 77,000 MW or 8.4 percent
(including uncommitted resources, 123,000 MW or 12.7 percent).” Source: NERC 2007 Long-Term Reliability Assessment

No matter which study or forecast you review, the answer comes out the same. We will not have enough electric power to meet our needs in as little as two years, if our current (pun intended) behavior doesn’t change. It the NERC assessment is correct we will have 5 percent less electricity than we need when 2018 arrives in less than ten years.

Don’t be an ostrich, take action. If you are a member of a rural electric cooperative your supplier belongs to the National Rural Electric Cooperative Association. They created a website that makes it easy for anyone to contact their elected representatives. I did it in about five minutes and you can do it too.

Go to https://www.ourenergy.coop and after reading that page, scroll down to the line that says "Contact your electric officials and begin the dialogue now". When you click the arrow at the end of this line, you will be asked to fill out your name and address to email your US Senators and US House of Representatives with the following message:

Our country faces a crisis as electricity use increases faster than available supply. I believe that by unleashing American ingenuity we can solve this problem. What are you doing to speed the development of new technology which will allow me to have the electric power I need while meeting our national climate policy goals? I look forward to your answer and will share it with my friends and neighbors. Thank you.

Then click “Send Message”, that’s it. You don’t even have to know who your representatives are. By filling in your name and address your message will automatically be sent to the correct representatives and you will get a brief confirming message listing which representatives were emailed on your behalf. It’s easy.

Let me know who it went and what you think about it.
