Wind Turbines (Onshore)
Wind energy is at the crest of initiatives to address global warming in the coming three decades. Today, 314,000 wind turbines supply nearly 4 percent of global electricity, and it will soon be much more. In 2015, a record 63 gigawatts of wind power were installed around the world.
The wind industry is marked by a proliferation of turbines, dropping costs, and heightened performance. In many locales, wind is either competitive with or less expensive than coal-generated electricity—and it has no fuel costs and no pollution. Ongoing cost reduction will soon make wind energy the least expensive source of electricity, perhaps within a decade.
Onshore wind farms have small footprints, typically using no more than 1 percent of the land they sit on, so grazing, farming, recreation, or conservation can happen simultaneously with power generation. What’s more, it takes one year or less to build a wind farm—quickly producing energy and a return on investment.
The variable nature of wind means there are times when turbines are not turning. Wind energy, like other sources of energy, is part of a system. Investment in 24-7 renewables such as geothermal, energy storage, transmission infrastructure, and distributed generation is essential to its growth.
