Clean technology includes recycling, renewable energy (wind power, solar power, biomass, hydropower, biofuels), information technology, green transportation, electric motors, green chemistry, lighting, Greywater, and many other appliances that are now more energy efficient. It is a means to create electricity and fuels, with a smaller environmental footprint and minimise pollution. To make green buildings, transport and infrastructure both more energy efficient and environmentally benign. Environmental finance is a method by which new clean technology projects that have proven that they are "additional" or "beyond business as usual" can obtain financing through the generation of carbon credits. A project that is developed with concern for climate change mitigation (such as a Kyoto Clean Development Mechanism project) is also known as a carbon project.

While there is no standard definition of "clean technology," it has been described by Clean Edge, a clean technology research firm, as "a diverse range of products, services, and processes that harness renewable materials and energy sources, dramatically reduce the use of natural resources, and cut or eliminate emissions and wastes." It notes that "Clean technologies are competitive with, if not superior to, their conventional counterparts. Many also offer significant additional benefits, notably their ability to improve the lives of those in both developed and developing countries". Many countries have developed clean tech representatives to speak about the countries problems some countries include Russia, Japan, and China.

Investments in clean technology have grown considerably since coming into the spotlight around 2000. According to the United Nations Environment Program, wind, solar and biofuel companies received a record $148 billion in new funding in 2007 as rising oil prices and climate change policies encouraged investment in renewable energy. $50 billion of that funding went to wind power. Overall, investment in clean-energy and energy-efficiency industries rose 60 percent from 2006 to 2007.^[1] By 2018 it is forecast that the three main clean technology sectors, solar photovoltaics, wind power, and biofuels, will have revenues of $325.1bn.^[2]

Cleantech[link]

Cleantech is a term used to describe products or services that improve operational performance, productivity, or efficiency while reducing costs, inputs, energy consumption, waste, or environmental pollution. Its origin is the increased consumer, regulatory, and industry interest in clean forms of energy generation—specifically, perhaps, the rise in awareness of global warming, climate change, and the impact on the natural environment from the burning of fossil fuels. The term cleantech is often associated with venture capital funds and land use organizations.

Overview[link]

The term cleantech first emerged in widespread use to describe a group of emerging technologies and industries, based on principles of biology, resource efficiency, and second-generation production concepts in basic industries. Examples include: energy efficiency, selective catalytic reduction, non-toxic materials, water purification, solar energy, wind energy, and new paradigms in energy conservation. Since the 1990s, interest in these technologies has increased with two trends: a decline in the relative cost of these technologies and a growing understanding of the link between industrial design used in the 19th century and early 20th century, such as fossil fuel power plants, the internal combustion engine, and chemical manufacturing, and an emerging understanding of human-caused impact on earth systems resulting from their use (see articles: ozone hole, acid rain, desertification, climate change and global warming).

Investment[link]

In 2008, clean technology venture investments in North America, Europe, China, and India totaled a record $8.4 billion. Cleantech Venture Capital firms include NTEC, Cleantech Ventures, and Foundation Capital. The preliminary 2008 total represents the seventh consecutive year of growth in venture investing, widely recognized as a leading indicator of overall investment patterns.^[4] China is seen as a major growth market for cleantech investments currently, with a focus on renewable energy technologies.^[5]

According to the published research, the top clean technology sectors in 2008 were solar, biofuels, transportation, and wind. Solar accounted for almost 40% of total clean technology investment dollars in 2008, followed by biofuels at 11%.

The 2009 United Nations Climate Change Conference in Copenhagen, Denmark is expected to create a framework whereby limits would eventually be placed on greenhouse gas emissions. Many proponents of the cleantech industry hope an agreement is established there to replace the Kyoto Protocol. As this treaty is expected, scholars have suggested a profound and inevitable shift from "business as usual."^[6]

The Clean are an influential indie rock band that formed in Dunedin, New Zealand in 1978, and have been described as the most influential band to come from the Flying Nun label, whose repertoire included many major proponents of the "Dunedin Sound".^[1] Led through a number of early rotating line-ups by brothers Hamish and David Kilgour, the band settled down to their well-known and current line-up with bassist Robert Scott. Early incarnations of The Clean included Peter Gutteridge on bass (who wrote "Point That Thing") and Doug Hood on vocals (who later worked with Toy Love and founded the "Looney Tours" touring company). The Clean forged a distinctive and quirky sound that relied heavily on organ melodies and simple, Ramones-style chord progressions.

History[link]

The band's auspicious 1981 debut single "Tally Ho!" was the second release on Roger Shepherd's Flying Nun label. Featuring a chugging rhythm and instantly memorable descending farfisa line played by Martin Phillipps of The Chills, "Tally Ho!" reached number 19 on the New Zealand Singles Charts, giving the fledgling label its first hit. Tally Ho was recorded for $50. A follow-up track on the band's Great Sounds Great EP titled "Beatnik" also achieved success, as did their second single, "Getting Older".

The Flying Nun label went on to become New Zealand's biggest independent record company, championing the Dunedin Sound, a loosely-connected style of music largely produced by bands from the southern city. Other artists on the label included The Chills, The Verlaines, The Bats, and Sneaky Feelings. The line-ups of these bands were often interrelated, with Peter Gutteridge being a founding member of The Chills, David Kilgour briefly in The Chills off-shoot band Time Flies, and Robert Scott being the founder of The Bats.

During much of the 1980s, The Clean disbanded, and during this time the Kilgour brothers worked together on an experimental album and EP using the deliberately punning titles "The Great Unwashed" and "Clean Out of Our Minds". Reforming in the late 1980s, the band explored a slightly poppier vein of music while still retaining their experimental edge.

Although they released several chart-topping singles in their native country, The Clean are a little-known cult band outside of New Zealand, although their influence is surprisingly far-reaching. They became a staple of college radio in the 1980s, Stephen Malkmus of Pavement cites them as a major influence, and the band's droney 80s output is a direct forerunner of bands such as Yo La Tengo and Camper Van Beethoven.

The Clean continue to produce music, with Flying Nun recently issuing a comprehensive collection of their previously hard-to-find singles. Output from the band has been sporadic over the years, with members involved in other projects and Hamish Kilgour living in New York. Other projects involving members of the band include The Bats and The Magick Heads (Scott), Stephen, The Heavy Eights (David Kilgour), and The Mad Scene (Hamish Kilgour).

In early 2007, The Clean toured New Zealand on their "Bangers and Mash" tour, during which they celebrated Hamish Kilgour's 50th birthday while playing at "The Studio" in Auckland on Saturday 17 March 2007. Later that same year, the band's best-known incarnation (Kilgour/Scott/Kilgour) reunited for a short East Coast tour of the USA. The tour began in Manhattan, NYC with four shows: an in-store performance at Other Music and a three night stand at the Cake Shop on the Lower East Side. Although the tour officially concluded with a performance at Johnny Brenda's in Philadelphia, the following week the band played an extra show at Maxwell's in Hoboken, NJ, opening for Yo la Tengo at one of the group's annual Hannukah concerts.

In June 2008 a live album recorded during the 2007 New Zealand tour was released in New Zealand on Arch Hill Records, entitled "Mashed". A new studio album, titled Mister Pop was released on 7 September 2009 on Arch Hill, and on 8 September in the United States on the Merge label.

The Clean announced their first European dates in more than 20 years, supporting the cult U.S band Pavement at Brixton Academy on 10 May 2010. They also played at Butlins Minehead on 14 May. Other dates on the tour included Amsterdam (22 May), Hamburg (23 May), Berlin (25 May) and Barcelona's Primavera Sound festival (29 May).
