Danish Wind Power: Alternating Currents

Abstract

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.
