Nowadays, due to the serious shortage of energy resource, the research and application of new alternative energy has become an important task for each country and government all over the world. In order to protect environment and raise the utilization of marine power, Maritime Environment Protection Committee (MEPC) of International Maritime Organization (IMO) encouraged ship operators to use new alternative energies to reduce marine CO2 emission. Currently, marine new energy technologies mainly include solar energy, wind energy, waste heat recovery and biological substitute fuel. Wind energy, as a clean and easy getting energy, has been paid a high attention to. This paper mainly introduces the basic features and calculation of wind energy, and then put forwards some shortcomings in the application of it on the ships.

Covering the energy demands under environmental protection and satisfying economic and social restrictions, together with decreasing polluting emissions, are impetuous necessities, considering that over half of the pollutant emissions released in the environment are the effect of the processes of electricity and heat production from the classic thermoelectric powerplant. Increasing energy efficiency and intensifying the use of alternative resources are key objectives of global policy. In this context, a range of new energy technologies has been developed, based on alternative energy conversion systems, which have recently been used more and more often for the simultaneous production of electricity and heat. An intensification of the use of combined energy production correlated with the tendency towards the use of clean energy resources can be helpful in achieving the global objectives of increasing fuel diversity and ensuring energy demand. The chapter aims at describing the fuel cell technology, in particular those of the SOFC type, used in the CHP for stationary applications.

Wind energy is an important alternative energy resource because of it clean, does not cause pollution and it can be used as replacement of a fossil fuel energy. Utilization of the wind energy, the wind speed data has to be analyzed to make sure before use it. In this article is to present the wind speed data analysis by using Weibull distribution method. Wind speed data from the meteorological station at Pakchong district, Nakhonratchasima province, Thailand was used as the case study. The results show that this area has wind speed about 2.5 to 3.5 m/s. The average wind power density was 17.513 W/m2 and the total wind energy was 153.9819 kW·hr/m2 per year. This wind potential of this area can be used for water pumping and electricity generating for use in a household.

Abstract About 20 years ago Klepper (1997) has shown that the life cycle theory, initially introduced for products, can also be applied to the development of industries. The industries that were examined to establish this theory were marked by relatively stable market conditions that are typically driven by innovation. However, research on the transition of the energy system has shown that markets for new energy technologies are driven by political support. As yet an analysis of the industry life cycle of an industry which has developed under politically driven market conditions has not been conducted. Therefore this paper examines the development of the global wind energy industry and the relevance of national markets in a globalized world. The study is founded on a large empirical database. A comparative analysis of various international and national developments was conducted using descriptive statistical methods. The findings show that the global development derives from the sum of individual national developments. It reveals a strong influence of national markets on the development of their respective wind energy industry. Therefore these findings provide relevant insides for the political debate on market support mechanisms in wind energy.

Currently, the emissions discharged by ships are becoming more and more serious, which brings a great harm to the atmospheric and marine environment. In order to solve the emissions, especially of CO2 emission, the new ship energy efficiency design index (EEDI) has been introduced to reduce it. According to EEDI calculation formula, the use of new energy technology can reduce marine EEDI. Nowadays, wind energy as a clean and renewable energy, is an ideal alternative energy to be applied on ships. But until now, there is still no definite calculation formula and value regulation to parameters involved in the application of new energy on ships, including new energy utilization coefficient.

Morocco depends on 85% foreign sources of its energy supply. The oil invoice accounts for nearly 22.3% income from exports. In Morocco, the use of wind energy began before 1930, through the importation of windmills from USA by the French colony, to pump water for livestock and population in the country. An estimated 1000 of these units were in use in Morocco [1]. Following the rising price of oil after the first oil-price shock in the early 1970s, the days of cheap and plentiful petroleum were drawing to an end. Morocco began to promote and develop renewable energy mainly solar energy. Wind energy is the most promising alternative energy resource in Morocco because of its good geographic location (3446 km of coast, Straits of Gibraltar, Rif and Atlas Mountain at 4167 metres and the Taza corridor) which permits Morocco to have available the largest wind potential in the North Africa. At 10 m, the annual mean wind speed can reach 11m/s in the Tetouan region and 8 m/s in the Dakhla site. The Moroccan wind potential is estimated at 21,000MW. In the framework of diversification of national energy resources, various actions have been taken for the use of wind energy as a national energy resource. It is mainly about: Since wind energy is economic on windy sites and the capital costs are continue to decline with the move to larger wind turbines [2,3], the Moroccan government has set a target of achieving 20% of its electricity supply from wind energy by 2020. It has started to pay attention to developing its indigenous wind energy resources and has encouraged wind technology transfer from other countries. On top of that, wind energy could have a significant and beneficial impact on the environment, particularly with regard to the greenhouse effect. - Diversifying the actors, both public and private, - Concluding consessional contracts between the National Office of Electricity (ONE) and private electricity producers using wind energy to satisfy theirs own needs, - Increasing the autoproduction threshold to 50MW with the aim of installing 1000MW by modifying the laws governing the electricity production.

World is now endangered by the threat of fuel source scarcity and environmental degradation. Researchers all over the world are searching for the alternative energy resources to supplement the present energy needs and to conserve the conventional resources from depletion which are less costly and environmentally friendly. Harnessing the wind power and its utilization is one of the best possible answers. Investigations for recent years have revealed that wind energy has been the great deals to the rural farmers for their water pumping. Wind power can be used effectively in maintaining livestock, water supply, fish & ice farming, water desalination, sawing wood, irrigation, electrification, agricultural operations etc. If all possible considerations are given in exploiting wind energy, in the coming 4 to 5 decades it can meet 30% to 45% of the world’s total energy demand contributing no unwanted emissions into the atmosphere. It can adjust more jobs and occupies fewer lands. It is cheaper than any other sources. Bangladesh possesses flat terrain, hilly & mountainous regions, open river banks & harbors, and a vast lengthy coastal belt by the sea “the Bay of Bengal” where reasonable wind flow round the year available. For most of the said areas, electricity supply from the mother grid is almost inaccessible due to various difficulties and limitations. Moreover, a total of 2105 MW national generation capability absolutely unable to meet the present suppressed peak demand of 2114 MW for the consumers already in the grid. This continuously causing a severe regular load shedding up to 30% of the peak demand. The large sized population of the above areas is being maintained over decades mostly from fuel wood, charcoal plant & agricultural residues, dung and very few from imported petroleum and derivatives as the only energy sources. The energy scarcity let the locality remained economically backward and noncontributing to the GDP. In some of the areas namely Chittagong Harbor, Coastal belts & City periphery, from recent observations the monthly mean wind speeds (m/s) ranging between 4.5 and 8.5 are recorded which show the genius prospect of reaping wind power in Bangladesh. Despite a promising future of this free fuel, benefits for utilizing this energy in Bangladesh are being missed because too little is known about either the resource or the technology. Wind energy can successfully be utilized in utility for supplementing our generation and to meet decentralized needs or wind-solar hybrids for Bangladeshi modern multistory buildings which are now meeting their energy deficit by individual diesel generators at higher money and environmental costs. In the context of Bangladesh, wind power to come to use, this paper is an attempt to describe the methodologies for site selection; wind data collection & regime modeling; power availability, conversion & storage; turbine performance monitoring & augmenting wind speed using cloth scoops including costs and environmental impact Assessment. This paper also discusses Bangladesh energy scenario and strategies for meeting deficit demand and summarizes global wind development and proposes that Bangladesh government and other agencies must take immediate initiatives towards implementing wind projects.

Energy is the lifeline and the base of development of social economy in every country or area. However, with the increasing depletion of fossil energy, it is imperative for business managers and government policy makers to seek and utilize new energy resources for keeping the national economy development sustained, rapid, and healthy. As a new energy resource, wind energy is developing with a high speed in the world for the reasons that it is an abundant natural resource with the characteristics of renewable, low cost, and no pollution. But in reality, forecasting wind speed accurately is continuously a challenging subject in the field of the wind energy development for a long time. In this paper, a novel ensemble wind speed forecasting model based on machine leaning models and hybrid models with data preprocessing technology is proposed to forecast the wind speed effectively in the Longdong area of Loess Plateau in China; numerical results show that the ensemble model has better precision, adaptability, and robustness.
