Renewable Energy

Renewable energy means solar energy, biomass, wind power, micro hydropower, fuel cell, liquefaction and gasification of coal, marine energy,

waste energy and others, and it does not include coal, oil, nuclear energy and ntural gas. In addition,

it includes fluid fuel mixing geotherm, hydrogen, and materials from coal.

But, real meaning of renewable energy is energy sources replacing oil in wider sense, and new and regenerative energy sources in narrower sense.

The Korean government designated renewable energy into 11 parts

 (Article 2 of the Law Promoting Development, Use and Distribution of Renewable Energy).

They are as follows.

 - 8 parts of Renewable energy: solar power, solar photovoltatic power generation, biomass, wind power,

   micro hydropower, geothermal energy, marine energy, waste energy

 - 3 areas of new energy: fuel cell, liquefaction-gasification of coal, hydrogen energy 

During the recent decade, energy consumption in Korea has recorded annual rate of 10% increase, the highest one in the world.

The rate of annual increase of global warming gas emission has also recorded number 1 in the world.

Fortunately, implementation of the Global Climate Accord has been postponed.

But, soon Korea has no choice but to participate in it. Thus, it becomes urgent to develop renewable energy.

As kinds of renewable energy which have been developed and are put to practical use in advanced countries, solar energy and wind energy are the most popular.

And, development of renewable energy using biomass, geothermal energy, wave power, and tidal power, etc. are actively underway. According to the Future Technology of the US published by George Washington University in 1998, 10% of energy consumption will be taken up by renewable energy.

And, according to the Energy White Paper published by the EU in 1997, the EU has a plan to upgrade the proportion of renewable energy two times to 12% by 2010.

In Denmark which can be described as the Mecca of wind power, 4,900 wind turbines produce electricity of 1,135MW, 7% of electric consumption in Denmark. Denmark is very active in developing renewable energy.

According to Its "Energy 21" plan, wind power will take up 10% by 2000, and 50% by 2030.
