Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land.The net effects on the environment are far less problematic than those of nonrenewable power sources.Wind farms consist of many individual wind turbines which are connected to the electric power transmission network.Onshore wind is an inexpensive source of electric power, competitive with or in many places cheaper than coal or gas plants.A wind farm is a group of wind turbines in the same location used for production of electric power.A large wind farm may consist of several hundred individual wind turbines distributed over an extended area, but the land between the turbines may be used for agricultural or other purposes.The ladders are easy to transport and manuever on the jobsite. The 7112-1 one-section round rung 12' straight ladder features a duty rating of 375 pounds and non-conductive fiberglass side rails.The ladders are easy to transport and manuever on the jobsite.

Wind-powered pumps drained the polders of the Netherlands, and in arid regions such as the American mid-west or the Australian outback, wind pumps provided water for live stock and steam engines.
As the proportion of wind power in a region increases, a need to upgrade the grid, and a lowered ability to supplant conventional production can occur.
Power management techniques such as having excess capacity, geographically distributed turbines, dispatchable backing sources, sufficient hydroelectric power, exporting and importing power to neighboring areas, or reducing demand when wind production is low, can in many cases overcome these problems.
Throughout the 20th century parallel paths developed small wind stations suitable for farms or residences, and larger utility-scale wind generators that could be connected to electric power grids for remote use of power.
Today wind powered generators operate in every size range between tiny stations for battery charging at isolated residences, up to near-gigawatt sized offshore wind farms that provide electric power to national electrical networks.
