Problem: As of 2014, the wind industry in the USA is able to produce more power at lower cost by using taller wind turbines with longer blades, capturing the faster winds at higher elevations. This has opened up new opportunities and in Indiana, Michigan, and Ohio, the price of power from wind turbines built 300 feet to 400 feet above the ground can now compete with conventional fossil fuels like coal. Prices have fallen to about 4 cents per kilowatt-hour in some cases and utilities have been increasing the amount of wind energy in their portfolio, saying it is their cheapest option.
How tall are old wind turbines that are being built in Indiana, Michigan and Ohio?

Presbyterianism is the largest Protestant denomination in Northern Ireland and the second largest on the island of Ireland (after the Anglican Church of Ireland),[citation needed] and was brought by Scottish plantation settlers to Ulster who had been strongly encouraged to emigrate by James VI of Scotland, later James I of England. An estimated 100,000 Scottish Presbyterians moved to the northern counties of Ireland between 1607 and the Battle of the Boyne in 1690.[citation needed] The Presbytery of Ulster was formed in 1642 separately from the established Anglican Church. Presbyterians, along with Roman Catholics in Ulster and the rest of Ireland, suffered under the discriminatory Penal Laws until they were revoked in the early 19th century. Presbyterianism is represented in Ireland by the Presbyterian Church in Ireland, the Free Presbyterian Church of Ulster, the Non-subscribing Presbyterian Church of Ireland, the Reformed Presbyterian Church of Ireland and the Evangelical Presbyterian Church.
In what year was the Battle of the Ulster?
