  • Energy from the Wind Student Guide
    2019-2020 Energy From the Wind Student Guide INTERMEDIATE Introduction to Wind Wind Average Wind Speed at 80 Meters Altitude Wind is moving air. You cannot see air, but it is all around you. You cannot see the wind, but you know it is there. Faster than 9.5 m/s (faster than 21.3 mph) 7.6 to 9.4 m/s (17 to 21.2 mph) You hear leaves rustling in the trees. You see clouds moving 5.6 to 7.5 m/s (12.5 to 16.9 mph) across the sky. You feel cool breezes on your skin. You witness 0 to 5.5 m/s (0 to 12.4 mph) the destruction caused by strong winds such as tornadoes and hurricanes. Wind has energy. Wind resources can be found across the country. Science and technology are providing more tools to accurately predict when and where the wind will blow. This information is allowing people to use wind on small and large scales. Wind is an increasingly important part of the United States’ energy portfolio.

  • Offshore Wind Initiatives at the U.S. Department of Energy U.S
    Offshore Wind Initiatives at the U.S. Department of Energy U.S. Offshore Wind Sets Sail Coastal and Great Lakes states account for nearly 80% of U.S. electricity demand, and the winds off the shores of these coastal load centers have a technical resource potential twice as large as the nation’s current electricity use. With the costs of offshore wind energy falling globally and the first U.S. offshore wind farm operational off the coast of Block Island, Rhode Island since 2016, offshore wind has the potential to contribute significantly to a clean, affordable, and secure national energy mix. To support the development of a world-class offshore The Block Island Wind Farm, the first U.S. offshore wind farm, wind industry, the U.S. Department of Energy (DOE) represents the launch of an industry that has the potential to has been supporting a broad portfolio of offshore contribute contribute significantly to a clean, affordable, and secure energy mix.

  • Energy Infrastructure Projects Progressing
    Consumer Liaison Group Meeting Summary September 15, 2016 Introduction The Consumer Liaison Group (CLG) is a forum for sharing information between ISO New England (ISO) and electricity consumers in New England. The CLG meets quarterly and attracts a diverse group of 75-100 attendees at each meeting. Meetings are open to the public. Participants generally include consumers and consumer representatives (including state consumer and ratepayer advocates), state business and industry associations, chambers of commerce, individual businesses, trade groups, nonprofit organizations, and other end users. Several New England Power Pool (NEPOOL) members and state regulators are also regular, active participants in CLG discussions.1 The focus of the CLG is on the concerns and needs of commercial, industrial, and nonprofit electricity end users. CLG meetings generally follow the same format: Opening remarks from a keynote speaker—typically, an industry or business executive, policymaker, or regulator—who provides a unique perspective on a particular topic or issue A representative from the ISO, who provides an update on regional energy issues and initiatives that have or will be taking place at NEPOOL and ISO stakeholder meetings that can have an impact on electricity prices A panel discussion, often representing industry, the ISO, regulators, and consumer perspectives, facilitated by a moderator The following is a brief summary of the meeting held on September 15, 2016 in Providence, Rhode Island. The topic, keynote speaker, moderator, and panelists were selected by the Consumer Liaison Group Coordinating Committee (CLGCC). The meeting summary is intended to capture the general discussions that took place at the meeting, but does not necessarily reflect the views of the ISO or the CLGCC.
