Solar energy class in Costa Rica and online

From Dr. Ken Walz, the course instructor:
The Madison Area Technical College (MATC) offers a new course: Renewable Energy for the Developing World Class.

The 3-credit, college transfer class combines 9 days of field study and hands on work in Costa Rica, with 8 weeks of additional online instruction.

The study abroad portion is being coordinated with Solar Energy International, and the online class is being created with funding from a U.S. DOE Title VI International Education grant. The class is being offered on a pilot basis starting in January, 2009. Students will travel to Costa Rica Jan 1-9, and the online course will be held Jan 12-March 14.

Registration for the class is currently underway, and a limited number of slots are still available. To register for the class, contact Diana Paynter at

Regrettably the workshop has been cancelled.

The number of registrations has not come close to the number needed to cover the workshop's expenses, and I can't imagine getting enough registrations in the next two weeks or so.

Those who registered will receive a full refund by mail.

Check back periodically, however. Centro Ecológico Akumal plans to hold a workshop on sustainable construction in November. I'll post the details when they become available.

I might plan another workshop on green homes when the global economy settles down.

If you live in the U.S. and want to take renewable energy courses, you could check the workshop schedule for the Midwest Renewable Energy Association (MREA).

Green Building & Renewable Energy Workshop, Nov. 6-8, Akumal

Green Homes & Renewable Energy in the Riviera Maya, a three day workshop, will be November 6-8, 2008, in Akumal, Mexico, 70 miles south of Cancun.

Whether you want to "green" your home or business in the Riviera Maya or anyplace else in the world, you'll gain invaluable insights from two exceptional green building and renewable energy professionals.

This is another in the series of sustainability workshops hosted by Centro Ecológico Akumal.

Co-sponsored by Yucatan Environmental Foundation, a U.S. 501(c)(3), RENEW Wisconsin, a non-profit promoting renewable energy, and Just Imagine Website services.

Register online or by mail.

November 6 - Green building and remodeling techniques and tools, including water and waste management
Presenter: Sherrie Gruder, Sustainable Design Specialist, LEED Accredited Professional

November 7 - Using the sun to make electricity and hot water
Presenter: John Hippensteel, Lake Michigan Wind and Sun*
John Hippensteel will give you the basic information about how PV and solar hot water systems work, how (and where) they can be installed, estimating system size, and other basics to help you become knowledgeable enough to proceed with confidence if you choose to install a solar system.

November 8 - Using wind to generate electricity
Presenter: John Hippensteel, Lake Michigan Wind and Sun*
John will cover the basics of residential size wind systems for your home or business. He'll cover wind resources, basic system components, system types, turbine types, applications, and tower types. You'll be better informed on wind's value to you and how to get started on an installation.

November 8 - Installation tours
The workshops will end with a tour of wind and solar installations at homes and businesses in the Akumal area -- solar hot water on CEA dorms; solar electricity on
the home of Bart Smith; solar hot water and electricity and wind turbines at Centro Ecológico Sian Ka'an (CESiaK) in Tulum. The tour is included in all registration, even a registration for only one of the three days.

For more information, contact Ed Blume.

* With the explosive demand for wind and solar installations, John cannot be 100% certain that he can get free in November. If he can't, the instructor will be someone of equal intelligence and expertise.

Organized by Eco-Yucatan, Inc. and Ed Blume, Director of Communications and Outreach for RENEW Wisconsin, a non-profit promoting renewable energy.

Renewable energy in tourism initiative: Best practices manual

From an article by Wendy Kerr in EcoCurrents, the membership magazine of The International Ecotourism Society (TIES):

The Renewable Energy in Tourism Initiative (RETI) has recently developed a set of Best Practices in Renewable Energy for the Tourism Industry and they can be downloaded for free at

Through the use of case studies, these manuals outline renewable energy adoption strategies that maximize energy efficiency, minimize environmental impacts, and result in cost savings or increased profitability across six tourism sectors: Accommodations, Airlines, Cruise Lines, Public Lands Agencies, Ski Resorts, and Tour Operators.

Tourism, the world’s largest industry, has a powerful impact on, and is greatly impacted by, the ecological health of its destinations across the globe.

One of tourism’s largest economic and environmental costs is the massive amount of energy required for the transportation of travelers and maintenance of facilities like hotels and attractions.

Thus, many businesses are eager to minimize their consumption of non-renewable energy, but are often uncertain on how to make it happen due to the technological complexity and rapid rate of innovation in field of renewable energy.

According to the lead authors at Sustainable Travel International, the RETI best practice manuals, “are intended to serve as an inspiration and guide to tourism businesses of all sizes interested in realizing the benefits of adopting renewable energy initiatives and supporting a healthy planet.”
Of course, the Green Homes and Renewable Energy workshop will help clear up the uncertainties of renewables for tourism operators, travelers, homeowners, and anyone interested in renewable energy.

Sustainable inn Balamku in Mahahual uses solar

An article in EcoCurrents, the monthly membership magazine of The International Ecotourism Society (TIES) highlights the sustainability practices and solar energy of Balamku, Inn on the Beach, in Mahahual south of Akumal:

Sustainability Practices at Balamku: Using the resources of nature without abusing the environment by Alan Knight and Carol Tumber

We believe that we have an obligation to protect the environment and reduce the impact of tourism by using eco-efficient energy and water systems, waste management practices, and by preserving the natural environment. . . .

All of our energy is provided by one of the largest solar panel installations on the Costa Maya.

There are 40 panels and 36 batteries in our system. Wind generation has been added to complement this solar system. It provides about 25% of our electricity and since there is almost always wind at night, our system loves this.

We supply our guests with 24 hour electricity without a generator pounding away in the background. . . .

Our water-saving, composting toilets are quite unique. As the waste is composted, toilet paper is put in the toilet and the black water is separated in the composting unit into a tank and used for large trees in our gardens. Water usage with these toilets is reduced from a normal gallon a flush to one pint. . . .

The planning design of Balamku considered the protection of the many local species of trees and plants. The units are situated to maximize natural ventilation. The beach has a beautiful stone wall to reduce the risk of erosion. Vines and shrubs have intentionally been left to assist in further reduction of soil erosion as well as for the enjoyment of their natural beauty.
The workshop Green Homes and Renewable Energy in the Riviera Maya, November 6-8, in Akumal will teach workshop participants about many of the sustainable practices used at Balamku.

Activities in Akumal and the Riviera Maya

You’ll have plenty to do (or nothing at all) when you’re not in the workshop.

Sunning, swimming, snorkeling, diving. The shallow, crystal-clear water and sandy beach of Akumal Bay (above photo) define tropical perfection. Dive shops are right on the beach. Ruins. The small, but stunning, Tulum ruins hug the sea 10 minutes south of Akumal, and the jungles hide many, many small sites that you can visit on your own or with a guide.

Restaurants. You can go from cheap eats at a tacoria in the pueblo or gourmet dinners at restaurants overlooking the bay.

Shopping. Playa del Carmen, 20 minutes north of Akumal, satisfies every shopping impulse!

Nature. Local guides can give you exceptional walks. CEA staff give entertaining and educational presentations nightly.

Maya culture. The unique ruins at Tulum are only a short ride south of Akumal. Coba and Chichen Itza aren't far either. has a useful desciription of these and others nearby.

Families. The shallow bay and laid-back pace of Akumal suit families with children of all ages. Make the workshop a vacation, too!
