And the state's coalbed methane, which is a source of danger, is easily recoverable but must be mixed with higher-BTU natural gas to upgrade its generation quality. Renewable sources of energy. The sun and the wind offer immense potential as clean souces of electricity. Passive use of solar energy in buildings is becoming more common than previously. Solar photovoltaic cells likewise are finding wider use.
Wind mills are another way to produce electricity.
They present a paradox to environmental advocates. Windmills are clean energy producers and they are impositions on pristine landscapes. In 2001 the West Virginia Highlands Conservancy and the power company agreed on changes to the project and on post-construction monitoring. In Preston County, MegaEnergy, Inc. plans to construct 10 windmills in conjunction with two small natural-gas fired generators. The Legislature in 2001 created a tax break for wind power companies by classifying wind turbines and towers as pollution control facilities.
