The creation and acceptance of new technologies has been speeding up dramatically in modern times. There are also significant uncertainties about the future shape of markets, governance and social values that will have an important impact on organizations and their capacity to meet their objectives. These rapid technological and social change and uncertainties make the upsurge of interest in technology foresight, giving rise to its emergence as a global concept and policy tool. A wide range of future methods are available for technology foresight. Selection of methods will depend upon several factors, most notably available and the time financial resources, and the objectives of the exercise. Although Delphi has been widely used for many years, scenario becomes very popular in recent years. The use of scenarios can take better account of the complexity and unpredictability of the economic, social and political environments. Scenarios tell the stories describing paths to different futures, which help organizations make better decisions today. In this study, the scenario method was employed to draw the images of the future of renewable energy. Renewable energy grows dramatically in recent years. However, there is still considerable uncertainty with regard to the potential of renewable energy due to environment regulation, energy costs, and political and economic developments in the main supplier countries for oil and natural gas. Scenario can help us to identify the risks and opportunities when we develop the renewable energy, and to prepare for them. The scenario method is expected to be more utilized in the national technology foresight.

Korean government decided to give a subsidy for renewable energy system of green home. This policy will make an appeal to consumers. But For success of this policy, Economic benefit of consumer is essential. In this study, benefit and cost is seperated to consumer part and government part, respectively. consumer's benefit is energy saving and asset value increment. Consumer's cost is real input money except government's subsidy. Government's benefit is consist of energy import reduction, carbon discharge reduction and new production increment, As a result, the government subsidy will not so enough to activate the green home. PV system for the korean general apartment has the payback period of 19 years. So, For the dissemination of renewable energy of green home, more strong subsidy policy and more economic technoloy development is requested.

Tidal power can use conventional technology to extract energy from the tides. It is usually best deployed in areas where there i s a high tical range which includes Western and Southern coastal areas in Korea. However, to extract tical energy, a barrage across an estuary or a bay is to be constructed that is now very hard due to severe environmental impact on local estuary. The recent technology of application of tidal stream provides a new window to extract power minimizing the adverse environmental impact Tidal stream technology which directly exploits these currents is relatively new but is presently generating considerable interest Turbine rotors can be used to extract energy from the flows. Prototype devices currently on test in the UK include the 300kW SeaFlow turbine. In this paper, the recent technology and research on ocean tical stream power are addressed

The importance of new renewable energy is emphasized not only new growth engine but also the key solution for the exhaustion problem of fossil energy and environment problem. For the steady growth of new renewable energy industry, securing related labor force is an essential factor. In this study, the status on labor force of new renewable energy industry was identified and forecasted the labor force demand of new renewable energy in 2015 by reflecting the industrial growth outlook on the new renewable energy. For the quantitative analysis methodology, the stock approach of Bureau of Labor Statistics (BLS) of the United States was applied. Also by performing survey on the experts, the opinions of experts on supply and demand of new renewable energy labor force or worker training programs have been gathered. As a result of study, it has been analyzed that nearly 20% annual growth rate will be shown as the labor force demand in the field of new renewable energy industry increases from 14,100 people in 2010 to 33,200 people in 2015. In the survey on experts, we could find that a plan for supplying labor force must be prepared promptly in order to accomplish new renewable energy supply objectives and industrial growth objectives by our country in the future as the supply of new renewable energy labor force is currently insufficient. Also, it has been analyzed that the effort for deciding the proper new renewable energy labor force training program standard will be necessary. This study result could be used as a material of labor force training plan for the steady growth of new renewable energy industry in the future.

The primary purpose of Renewable Portfolio Standard (RPS) is to facilitate investment in renewable energy technology. Since emission trading program has similar purpose, it is conceivable to attempt to link RPS and emission trading program through interlinked markets. RPS in Korea with single REC and emission allowance markets has particular advantages for constructing linkages between two markets. This paper provides a real option model to examine investment effects of linkage of RPS to the trading program. Emission permit price and REC price are assumed to follow stochastic processes and renewable investment is irreversible. The result shows that linked market provides further incentive for renewable investment by raising managerial flexibility for power companies.
