Massachusetts

The U.S. state of Massachusetts has vast wind energy resources offshore, as well as significant resources onshore. The 2016 update to the states's Clean Energy and Climate Plan had a goal of reducing 1990 baseline greenhouse gas emissions levels by 25% by 2020. Current goals include installing 3,500 megawatts (MW) of offshore wind power in the state by 2035. However, as of Q4 2021 the state had only 120 MW of wind powered electricity generating capacity, responsible for generating 0.9% of in-state electricity production. The state has awarded contracts to two offshore projects, the 800 MW Vineyard Wind project and 804 MW Mayflower Wind project. Construction began on the Vineyard Wind 1 project on November 18, 2021, after a long fight for approval.Commonwealth Wind was selected for development in 2021, but the developer has attempted to cancel the project due to increased costs. There are eight projects planned for off the southern coast of Massachusetts, though some will deliver power to Rhode Island, Connecticut, and New York.

Climate change in Massachusetts affects both urban and rural environments, including forestry, fisheries, agriculture, and coastal development. The Northeast is projected to warm faster than global average temperatures; by 2035, the Northeast is "projected to be more than 3.6°F (2°C) warmer on average than during the preindustrial era."

U.S. Bicycle Route 7 (USBR 7) is a north–south U.S. Bicycle Route that follows the Western New England Greenway in Connecticut, Massachusetts, and Vermont in the United States.

Massachusetts ( MASS-ə-CHOO-sits, -⁠zits; Massachusett: Muhsachuweesut [məhswatʃəwiːsət]), officially the Commonwealth of Massachusetts, is a state in the New England region of the Northeastern United States. It borders the Atlantic Ocean and the Gulf of Maine to its east, Connecticut and Rhode Island to its south, New Hampshire and Vermont to its north, and New York to its west. Massachusetts is the seventh-smallest state by land area. With an estimated population of over 7.1 million, it is the most populous state in New England, the 16th-most-populous in the United States, and the third-most densely populated U.S. state, after New Jersey and Rhode Island.

Massachusetts was a site of early English colonization. The Plymouth Colony was founded in 1620 by the Pilgrims of Mayflower. In 1630, the Massachusetts Bay Colony, taking its name from the Indigenous Massachusett people, also established settlements in Boston and Salem. In 1692, the town of Salem and surrounding areas experienced one of America's most infamous cases of mass hysteria, the Salem witch trials. The American Revolution originated in Massachusetts, with Boston becoming known as the "Cradle of Liberty" for its political agitation. In 1786, Shays' Rebellion, a populist revolt, influenced the United States Constitutional Convention. Originally dependent on agriculture, fishing, and trade, Massachusetts transformed into a manufacturing hub during the Industrial Revolution. Before the American Civil War, the state was a center for the abolitionist, temperance, and transcendentalist movements. During the 20th century, the state's economy shifted from manufacturing to services; in the 21st century, Massachusetts has become the global leader in biotechnology, and also excels in artificial intelligence, engineering, higher education, finance, and maritime trade.
