Conservatives call into question highly successful feed-in tariff

There is a reason that Germany has half of the world’s installed solar generating capacity, and it is not the Northern European country’s boundless sunshine. Renewable energy capacity has achieved such tremendous growth because of the German government’s aggressive energy policy.

The policy vehicle responsible for the rapid acceleration of the country’s renewable energy capacity, known as a feed-in tariff (FIT), guarantees a fixed-rate of return for homeowners and farmers who install solar, wind, small hydro, biomass, and methane capturing systems and sell their surplus electricity back to the grid. Germany has Europe’s highest feed-in tariffs, allowing consumers to earn around 40 euro cents ($0.62) per kWh compared to paying retail rates of 18 euro cents per kWh after taxes and support fees.

Electricity generated through Germany’s feed-in law produces about 50 terawatt-hours (billion kilowatt-hours) of electricity per year, or nearly 15% of German electricity consumption (1). This adds an average of only 1.01 euros ($1.69) a month to a typical home electricity bill.

Bu, despite the law’s success, conservatives in the German Bundestag want to ratchet back the incentives that support renewable energy development.

It’s been suggested by some that the popularity of the Toyota Prius was brought about not by it’s technology, but by marketing - leading edge technology perception, and the gadget factor of that LCD display showing you how much energy you were regenerating made it a must have for many gadget nuts.

So could the same hold true for solar energy? There is a certain coolness factor to generating your own electricity, and just like the Prius you get a nifty display showing the amount of energy being produced by your solar installation.

However, there are few people in Europe who fully understand solar power, with many believing it to be too expensive or impractical in the less sunny parts of the continent. With this in mind, the European Photovoltaic Industry Association has organised ‘Solar Days’ this weekend in Belgium, France, Germany, Italy, the Netherlands, Portugal, Spain, Slovenia, Switzerland, Denmark, Norway and Britain.

Aesthetic. Original. Functional. Who knew solar panels could make a statement?

Apparently Peter Richardson knew when he submitted a winning solar design to the International Design Awards. His idea is to turn disused water ways into functional space by populating them with solar panels shaped like water lilies. Aiming to increase quality of life, while generating energy, the lilies so impressed the Glasgow City Council that they expressed interest in developing a pilot project.

The technology itself is easily within reach:

“They can be moved and dismantled and are simply tethered to the river bed, integrated motors can rotate the discs so their orientation to the sun is maximised throughout the day.” (Project Description)

In other words, no new technology required, just some clever design. My concern would be recreational or commercial river traffic (how “disused”must the waterway be?). Would waves from wake disrupt the solar lilies? What about an impact on wildlife or wildlife’s impact on the panels? What if the river ices over in the winter? One hopes a pilot project would figure out the kinks.

What do readers think - would a product like this in your local water way make an impact on your community? (More images here)

Last week, UCLA Anderson hosted the California Clean Innovation conference to facilitate the new ideas that will drive the future of clean technology. I must admit to being a bit intimidated by the topics to be discussed - I’m far from technically inclined - but the event was well done and I learned a ton.

First, what we’re all interested in…the moolah. I’ve been hearing a lot about the investment going into clean tech these days. The first keynote speaker, Ira Ehrenpreis of Technology Partners in Palo Alto also explained why this is so.

Editor’s note: Today, we’re pleased to start a content partnership with GreenBuildingTalk, “the place to share, ask, and learn about green building products and methods.” The site’s forums are both active and informative, and they’ve now started blogging. Today’s post on solar hot water was originally published on May 5, 2008.

Each week, the Chicago Architecture Foundation and Chicago Green Technology Center graciously host “lunch time seminars,” inviting some of the leading industry professionals to discuss building issues they are involved with. On 5/1/08, they hosted Joe Gordon’s “Solar Hot Water and Heating- Is It Right for You?” presentation. The seminar provided the audience with information on how solar thermal works, how much space you’ll need, incentives, and how to determine cost benefits. Mr. Gordon also discussed how the cost of solar hot water and heating will likely keep increasing, due to the high cost of copper that is used in these systems.

Joe Gordon has worked for Solar Service, Inc. for over four years and has fielded thousands of inquires from developers, architects, owners and institutions about whether solar hot water and heating would work for them. Visit Solar Service’s gallery to see unique ways panels can be installed.

They’re probably drinking a lot of beer in Quqiao village, in Shaanxi Province, China.

Ma Yanjun, a carpenter, said he wanted his mother to be able to enjoy a comfortable shower anytime, and since a solar water heating system was too expensive, he devised a way to make one of his own.

Using only water-filled beer bottles and connecting hoses, Ma’s mother now has hot water on demand, and so do more than 20 other families [...]

The people of an impoverished southern African nation have everything to thank the Sun for; because a new revolution is sweeping across rural Malawi, lighting up village communities with cheap solar lamps that almost everybody is now able to afford.

The problem has been that access to modern electricity is but a privilege for the few who can afford it, and the majority are burning kerosene for lighting, a practice known to be expensive, dangerous and harmful to health.

An initiative run by Solar Aid, in partnership with the UK non-profit, TRAID, the project is geared toward protecting the environment and reducing poverty by introducing simple, locally assembled, affordable LED solar lanterns to the poorest communities, providing residents with a cheap alternative to kerosene while also generating employment opportunities for the underprivileged and ill.

Solar System Powers Donggwang Green Village on Semi-Tropical Jeju Island

Donggwang is on the western half of Jeju-do, the largest of South Korea’s semi-tropical southern islands. Near the village, Halla Mountain, a volcano and the tallest mountain in South Korea, rises from the island’s center amidst a patchwork of small farms.

Donggwang has achieved what even the most powerful countries in the world are still struggling to accomplish: total energy independence with clean technology.

Green tourism is a more popular form of tourism. general travel is going more green. But more expert say that the global warming is also caused by travel.

Citing green hotels, coconut oil fuel for airlines and even recyclable golf tees, executives in one of the world’s largest industries say they are urgently trying to shrink tourism’s oversized environmental footprint.

But with global travel projected to keep soaring, and those very leaders still

In many ways, Shinhyocheon is just a typical suburb. It’s in Nam-gu, on the southern outskirts of Gwangju, one of South Korea’s biggest cities. In fact, if you don’t look closely, the Shinhyocheon solar village is easy to miss. Of the 1.4 million people living in Gwangju, most have never heard of it. Local taxi drivers wrinkle their brows and shrug; even the tourist information center in downtown Gwangju has trouble finding it on the map.

But for those who know it, Shinhyocheon deserves a place in energy history. In 2004, it became South Korea’s first solar village – a neighborhood of 64 solar powered houses where residents enjoy cheap, clean energy. The solar panels in this neighborhood generate over 115 MW of energy in a year. For each resident, that translates into an annual savings of around $589 USD, or a total of $37,700 for all 64 houses combined.

Inspired by Shinhyocheon’s success, the local government is planning to expand the number of solar houses in Nam-gu by adding 340 new sun-powered residential buildings.

Everything is going green these days, even Barbie (NOT!).  Hasbro is introducing the first world edition of its classic board game Monopoly featuring renewable energy.  Wind energy and solar energy will replace the utilities of water works and the electric company. Phil Jackson, Group Executive, Hasbro Games stated,  “In a nod to the efforts of countries worldwide to increase the effectiveness and availability of renewable energy sources, we decided to feature Solar [...]
