Notes from Clean Energy Meeting, Kihei March 17, 2011

AGENDA:

  • Situation in Japan
  • Reation what can we do
  • Why 2011 is “Solar Year”
  • Solar Investing
  • Action Items in Maui and Honolulu
  • Kanu Hawai’i – July energy challenge

JAPAN

  • The reactors are out of control.
  • The situation is worse than Chernobyl, which had 1 million deaths. Now there are 6 reactors compared to 1 in Chernobyl. Some commentators say this is 500 times worse.
  • Reactor 3 is run partially on plutonium which is 1000 times more dangerous, experimenting with MOX for 3 months 5-15% plutonium
  • A Google news search for plutonium incidents shows that the US media doesn’t report them, but they are big news in Germany.

What can we do?

  • Set up a web page with radiation information. Click here to see this new posting.
  • Discussion: Should we start a Facebook page for distributing information about radiation risks and protection on Maui? What organizations already exist here with those resources?
  • Call for replacing nuclear with clean energy, wind, solar.
  • The Sierra Club already has anti-nuclear position, but it hasn’t started to point what we should be learning from the Japanese events and implementing in the U.S. We are prompted to encourage the Sierra Club to more actively to promote renewable energy in place of nuclear.
  • There is much discussion now on the internet about nuclear risks and suggested political actions.
  • There is also some information about the risks on Maui from the Japanese nuclear accidents and recommended precautions.
    Click here for some online resources as of 3/18/11.
  • Radioactive Iodine (Iodine-131) was major risk from the Chernobyl nuclear plant meltdown is not as big a factor with the current situation, which is leaking more Cesium.
  • For radioactive iodine, potassium Iodide is recommended, but only when person is exposed. It’s absorbed by the thyroid, which then doesn’t take in the radioactive substance.

    Good natural sources of iodine are edible seaweed, like nori, kelp, dulse and irish moss as well as asparagus, garlic, lima beans, mushrooms, seafood, sea salt and fortified salt, sesame seeds, soybeans, spinach, summer squash, swiss chard and turnip greens.

2011 SOLAR YEAR

  • PV costs have come down to between $2.80/watt (Germany) and $6.50/watt (US).
  • Chinese thin wafer technology is less expensive but can fracture more easily.
  • China is installing a new coal plant each week.
  • Safe nuclear? This is a problem because of the long half life of nuclear waste, which contains certain radioactive elements (such as plutonium-239) from “spent” fuel that will remain hazardous to humans and other creatures for hundreds of thousands of years. Other radioisotopes remain hazardous for millions of years.
  • What is needed is the political will to make the change to clean energy happen sooner. Because of the wealth and lobbying power of the established oil, coal and nuclear suppliers , this is a huge challenge. How can we make the change?
  • Suggestion: Lease rooftops to MECO to generate electricity.
    Response: MECO did survey about this and found it difficult to manage a large number of small roofs.
  • One problem with locally generated clean energy is the limited capacity of the grid to take variable energy. Reliable forms of storage are needed, perhaps incentives for homeowners to get batteries to store sun and wind generated electricity during high production and and installation of available systems that let individual batteries feed back into the grid at specific times of day, like peak demand between 7-9pm.
  • Currently the best batteries are Lithium-Ion batteries.
  • Energy can also be stored by Pumped Hydro systems, but local studies about feasibility of pumped storage at Ulupalakua revealed serious problems regarding environmental impact statements and getting permits.
  • A planned reservoir in upcountry has a cost of $100 million to build and an 18-year of permitting process. Two of those would be needed for pumped storage. MECO is only worth $100 million and they burn $300 million of oil burned/year, which is paid for by consumers. It is hard for them to invest $100-200 million in a storage system.
  • The Lanai PV farm was designed to store energy, but the battery company failed and the Chinese bought it. Lanai is just now getting a new battery.
  • The new FIT (Feed-in-Tariff), policy allows an electricity producer to upload a maximum of 250 kw to MECO for 20 years at a guaranteed rate of 21-27 cents per kw hour.
  • Net metering is better for homes than FIT, however, a producer can have a FIT meter on a separate meter from the Net Meter.

SOLAR INVESTING

  • An investment in a PV system with a 6% interest loan gives power costs for 30 years between 14-33 cents / kWh. MECO currently charges $0.30-0.34/kWh and that will likely only get higher.
  • Inverters for PV systems are warranted for 10-15 years and will likely be replaced because of limited lifetime and improvements in technology.
  • The PV modules have 10 year warranty, but can least for up to 40 years if not damaged by a big voltage surge, people walking on top of them and creating micro fractures, or getting serious corrosion on the terminal or getting water seepage.
  • The resulting return on a PV system is between 8% and 13%, depending whether tax incentives are utilized.
  • This grows to a 31% annual return in 20 years (considering a 5.5% increase in kWh prices)
  • Commercial systems pay off in 2-4 years –
  • Investments in solar parks yield 7-14%. A solar park is where people rent out their land or their roof and others invest in the PV installation.
  • One problem is that the rush to install at the end of the year for tax write-offs chokes installation process with over demand of limited supplies.
  • People need to learn how to use the tax benefits that are year-round.
  • Need to have clean energy education for architects and bankers.
  • LEED (international green building certification system) points are given for generating energy, but not for design. Because of the current low economy, there are few LEED projects on Maui now.
  • PV installation also protect roofs, but you need to start with a roof in good condition.

PROMOTING SOLAR ENERGY

  • Signs in front of PV homes or stickers on their mailboxes could show the trend.

GARAGE AND CARPORT PV SYSTEMS.

  • These are very practical, can be placed in parking lots, give shade to parked vehicles and provide power for all the associated businesses or homes.

PV IN THE GARDEN

  • Alternating PV pipes and open space can make the right amount of shade for vegetables like tomatoes. Some panels let sunlight through and could also be installed in gardens.

GROUND MOUNTED PV SYSTEMS

  • Ground mounted systems require a building permit and they must be engineered.

SOLAR HOT WATER

  • Solar hot water was tested by, and standards developed in part by the utilities. Now it is mandated for new construction, but regulations and enforcement were not mandated. The mandate eliminated solar hot water tax credits and rebates and costs the state money for inspection. Contractors also must be trained to properly install the units.
  • Architects also need to be educated about locating solar electricity and solar water units appropriately, too limit length of pipes from source to end use.

SOLAR SHINGLES

  • These are made from amorphous materials and serve a double purpose, but are not yet efficient enough to be really practical.

WIND POWER

  • The Small Wind Power market is still developing.
  • The vertical axis installation at the MECO office is wobbly. Same problem at the UHC. The 20′ height above the bearing creates cantilever problems on bearings.
  • All wind units get energy from their “swept area”, which is one of the most important factors in predicting energy production
  • Vertical wind turbines swept area is half the cage size because because half of the time it’s rotating into the wind.
  • The small turbines at the Ma’alea aquarium are challenged to follow shifts in wind direction.
  • Wind turbines must be high enough to avoid turbulence, which kills energy production.
  • Wind power provides better dollar per kw hours than solar in a good wind resource.
  • Durability is issue with wind equipment. There’s a 20-year design for the better units.
  • The first big Maalea turbine fell apart each week because it was an old design that wasn’t  made for the salt environment)
  • The <i>First Wind</i> farm now has storage in the form of a semi-truck sized GE battery. Their new farm will go up soon. Huge pieces of the new windmills can be seen stored beyond the fence at the end of South Holopono Street in the Maui Research Park.
  • Land is leased from the state by First Wind. Customers pay MECO which pays First Wind which pays state.
  • When excess energy is generated, it can be curtailed  by stopping the windmill from turning.
  • Construction has begun at the Auwahi Wind Energy 22-megawatt wind energy and battery storage project near Ulupalakua. Because it’s at end of power line, it needs a massive 30 MW battery.

Clean Energy Meeting – Kihei – March 17

2011 is a landmark year for Clean Energy. Recent technological advances, cost reductions and generous government support make investing in solar and wind generation highly lucrative. New governments in Maui County and Hawaii State have pledged their support for a swift reorientation away from oil.

Join us this Thursday, March 17 at 6:30 pm for a spirited discussion of investment possibilities for individuals and recommendations for Maui’s transition into an oil free future.

Energy Revolution
How to get Maui off oil by 2020

By Chris Mentzel

The central question about the introduction of renewable energy is WHO will do it. It’s not anymore about necessity, technology, finance and practicality – those have been proven and are available. But revolutions depend on the people who will bring them forward.

Consider the last revolution with massive impacts on our daily lives, the structure of our society and the distribution of wealth and knowledge. In a little more than a decade, people have embraced wireless technologies from the cellular phone to satellite TV to wireless Internet.

This change was not driven forward by government planning or the existing telecommunication companies with their huge investments in wired networks. Instead it was driven from the ground up by countless entrepreneurs, inventors and users that embraced a new technology and the autonomy it brought them.

In Bangladesh, Grameen Shakti has brought a network of ingenieurs and installers, most of them female, into place who have installed 1.5 million PV systems in less than 10 years. That was just the beginning, tens of millions are in the plan. For comparison – Maui has 800 PV systems, we are outrun by one of the poorest countries on earth.

In Germany, the Feed-in Tariff has created $130 billion in renewable energy investments in 10 years, ten times more than all the investments of the traditional energy sector. Income from clean energy systems mostly benefits the middle class, rather than large corporations. The law is so successful, that the government is trying to reign it in for fear of destabilizing the traditional energy sector.

In summary, the fastest progress has been achieved by involving many players in the society at large, especially when they are less hampered by laws or the involvement of the existing industry. Many small energy systems can be installed in weeks, rather than in years or decades like large power plants.

Locavore Potluck & “Two Angry Moms” movie

Two Angry Moms
Dinner & A Movie
Thursday, December 9
6:00 PM
Kihei Charter School [map]

Back to our usual 2nd Thursday of the month, join us for a fun and educational evening featuring great food and a movie about improving the food our kids eat. And pick up a few Compact Fluorescent Light Bulbs (CFLs) to go!

We’ll start off at 6:00 with a food prep demo by Chef Andrea of Whole Foods. She will demonstrate an item that could be part of a healthy school lunch made of local ingredients like mac nut butter, apple banana and honey sandwiches on HomeMaid Bakery bread.

At 6:30, we’ll socialize and enjoy the potluck local dishes that everyone has brought. Please bring a dish to share made from predominantly Hawaii Grown/Produced ingredients. It should be labeled for ingredients and boldly noted if it is VEGAN, CONTAINS MEAT, etc. Please make the effort to have your dish on the table prior to 6:30 so everyone can share the food. This is also a trash free event, so bring your own eating utensils.

After a quick dinner (7:00 P.M.) we’ll be showing the movie, Two Angry Moms. This is a true documentary about (you guessed it) two angry moms who decided to try to change school lunch programs. Learn more about what our kids are fed at school and what we can do about it.

UH Maui College’s Go Green Club, in an arrangement with the Blue Planet Foundation is giving away free CFLs. The Go Green Club, is made up of students involved in greening the UH Maui College through such planned initiatives as setting up a office paper recycling on the campus, will receive $400 for their club from the Foundation by collecting the names of people receiving the bulbs. We’ll have bulbs at our event and all you need to do is submit your name.

Everyone is invited. Follow the SMS blue and yellow signs from Pi’ilani Highway and Ohukai to find the high school.

See preview and clips of Two Angry Moms .
