Wind and Solar Background Information

Bryant University

Wind and Solar Project

Background Information

As the global climate continues to grow warmer we find ourselves searching for new ideas and ways to create and use alternative forms of energy. As a part of Bryant University’s new green initiative we hope to initiate the process of using wind and solar energy source on campus in order to do our part in reducing our footprint and working to create more sustainable business practices. The main focus of this study is wind and solar energy. Wind and solar energy are closely related in that wind is a form of solar energy. Wind is caused by three factors, the uneven heating of the atmosphere by the sun, inconsistencies of the earth's surface, and rotation of the earth. Wind turbines use the wind created by these three factors to make electricity. Wind turbines vary in size depending on location, and create energy by spinning a shaft that is connected to a generator, which makes the electricity. Turbines range in size from 100 kilowatts (7-25 ft in diameter) to several megawatts. Smaller sizes are used for smaller projects and can be installed on rooftops. Larger turbines have the ability to power large cities. Wind power is very useful to humans because it can be used to generate much needed electricity or mechanical energy.

RIWINDS Offshore, a proposed wind farm to be developed consisting of both on and off shore facilities, has the potential to meet 15% of the state’s total electricity consumption. In Rhode Island, many opportunities exist for businesses and residences to take advantage of wind and solar power.

Solar energy can be converted to electricity through the photovoltaic effect or by heating a transfer fluid to produce steam that runs a generator. Solar panels that contain photovoltaic cells react with the sun can also be used to create renewable electricity. PV cells must be covered with glass, in order to protect them from the environment. Solar panels range in size and can be located on top of roofs or in yards.

Bryant University is located in Smithfield at the top of a hill, garnering sources of strong wind throughout the year. The university’s solar exposure is subject to typical New England weather, which ranges from sunny and hot to cloudy and cold, with snowy conditions occurring during the winter months. Despite the cold New England winters, solar power could be used Bryant to supplement winter heating expenses. Many solar and wind power companies exist in Rhode Island and the New England area that are available for installation of devices to serve personal or corporate electrical needs.
