Solar
cities of the world
Freiburg of Germany : Cradle of Solar tourism
Freiburg, known as the ¡®environmental capital of Germany¡¯
or, ¡®the city of Solar Energy¡¯, is the frontrunner
in development and application of renewable energy.
Many alternative energy developers, educational institutions,
corporations have their headquarters in this small
city.
And residential life in this city is mainly supported
by renewable energy system, accordingly making this
city the best venue for the Solar-city tourism.
Freiburg is also well-known as the city of the annual
International Solar Energy Exhibition, the biggest
convention of this kind, which is held here every
year. In 2003, 240 corporations from 17 countries
participated in this show, making the show one of
the most crowed renewable energy shows. Lots of other
exhibitions and conventions related to renewable energy
are held in this city, too.
Goteborg, Sweden : the city of Solar tourism
Goteborg is in the process of being transformed
from a manufacturing ground into a technology-uploaded
city, with new business-sectors included in local
economy, such as car-making, bio and medical industry,
environment conservation and IT business. This city
is well-known as the ¡®Goteborg 2050 Project¡¯. The
goal of this project is to replace all energy it
consumes with renewable energy. This effort began
in the late 1980s. The city set and applied high
standards to reduce emission of pollutant from oil
refinery and other factories. The city encouraged
local corporations to produce environment friendly
products, too. In 1994, the city established the
Office of Supply in order to disseminate and encourage
people to buy environment-friendly products. The
city developed some environment stickers that are
shared by only environment-friendly products produced
by local manufacturers.
Kalunborg, Denmark : Industrial Symbiosis System
Kalunborg, one of Denmark? industrial cities, is
known for its industrial symbiosis system, which
is called as the archetype of eco-industrial complex.
Under this system, industrial waste from a factory
is sent to other factories as energy resource, and
vice versa. According to Kalunborg Industrial Development
Council, this system helps save 1.9 million§© of
grand water, one million§© of surface water, 20 thousand
tons of oil, 200 thousand tons of gypsum. This system
fulfills both economic and environmental goals by
reducing cost and toxic industrial wastes at the
same time. In the long run, the city aims to achieve
the goal of zero-industrial-waste by expanding its
symbiosis system to every sector of the industry.
Sacramento, U.S.A. : the City of the Sun
Sacramento, capital city of California State, U.S.A.
is called as the City of the Sun. The city is formally
approved as the Solar City by the International
Energy Agency (IEA). Sacramento has more solar panels
or, rooftop generators, than any other city in the
world. It also has the largest solar power station
in the world. 300 buildings and 700 houses in the
city have solar power generation systems. These
solar power systems in this city have the capacity
of generating about 10MW, which is enough electricity
to support 3,300 households or, ten thousand citizens.
The solar power generated in Sacramento is near
50% of the whole solar electricity that is generated
in U.S. Sacramento¡¯s remarkable progress in using
renewable energy is result of the effort by local
government and the people of Sacramento that tried
to maximize the unique geographical and climatic
idiosyncrasy.
