According to Michael Zarin, Director of Government Relations with Vestas Wind Systems, there is nothing “alternative” about wind power anymore (Biello, 2010). After all, wind generation is the most cost-effective option for new grid-connected power in markets like Mexico, South Africa, New Zealand, China, Turkey, Canada, and the United States (Renewable Energy Policy Network [REN21], 2016). At 433 GW of cumulatively installed capacity in 2015 worldwide, more than half was added in the past 5 years (REN21, 2016). This technology may be used by individuals, communities, and utilities. It can be grid-connected or off- grid, and be used onshore or offshore. This chapter examines the influences and evolution of the Danish wind transition, highlighting how ingenuity and often less-obvious incremental advances produced a world-class industry. It reveals how citizens can be important catalysts of energy system change. The case also indicates that innovations can emerge in practices and policy, not just technology, science or industry. Denmark is a cultural and traditional technology leader for modern wind power. This country of roughly 5.6 million people and GDP of approximately $65 billion in 2016 (ppp) (Central Intelligence Agency [CIA], n.d.) is where today’s dominant, wind turbine design was established and where state-of-the art wind technology testing centers are based. It is also the site of the first, commercial-scale offshore wind farm, built in 1991. Denmark has a world-class hub for wind energy technology (Megavind, 2013; State of Green, 2015; Renewable Energy World, 2016). Top-ranked companies like Vestas, LM Wind Power, Siemens Wind Power, A2SEA, and MHI Vestas Offshore Wind are among those that base core parts of their global operations in Denmark. A close network of wind engineers and their professional affiliates drives the industry, which includes ancillary services and subcomponent supplies. Wind energy technology also represents one of Denmark’s top-ranked exports (United Nations Comtrade, n.d.). Currently, Denmark has more wind power capacity per person than does any other country in the world (REN21, 2017). This Northern European nation is on track to derive 50% of its electricity from wind power by 2020.

This paper examines the dual efficiency of bioenergy, renewable hydro energy, solar energy, wind energy, and geothermal energy for selected OECD countries through an integrated model with energy, economic, environmental, and social dimensions. Two questions are explored: Which renewable energy alternative is more dual efficient and productive? Which renewable energy alternative is best for a particular country? Data envelopment analysis (DEA) is used for the efficiency evaluation, and the global Malmquist productivity index is applied for productivity analysis. Results indicate bioenergy as the most efficient renewable energy alternative with a 20% increase in average efficiency in 2016 compared to 2012. Renewable hydro energy, wind energy, and solar energy show a 17.5%, 16%, and 11% increase, respectively. The average efficiency growth across all renewable energy alternatives signifies major advancement. Country performance in renewable energy is non-monolithic; therefore, they should customize their renewable energy portfolio accordingly to their strengths to enhance renewable energy efficiency. Renewable hydro appears to have the most positive productivity change in 2016 compared to 2012, while solar energy regressed in productivity due to its scale inefficiency. All renewable energy alternatives have relatively equal average pure efficiency change. The positive trend in efficiency and productivity provides an incentive for policy makers to pursue further development of renewable energy technologies with a focus on improving scale efficiency.

As the trend of large-scale wind Power, People pay more attention to wind energy, which as a clean, renewable energy. Traditional unarmed climbing and crane lifting has been unable to meet the requirements of the equipment maintenance. Magnetic climb car can automatically crawl along the wall of the steel tower, the maintenance equipment and personnel can be sent to any height of the tower. The quality of the magnetic wall-climbing car is 550kg, which can carry 1.3 tons load. In this paper completed the magnetic wall-climbing car design and modeling, mechanical analysis in static and dynamic, obtained with the air gap and Magnetic Force curves. The application shows that the magnetic wall-climbing car meets the reliable adsorption, heavy-duty operation, simple operation etc..
