The green building movement is changing the way buildings are constructed. This movementstarted in the 1970s, as people began to see that modern life was destroying the environment we allshare. Natural resources were being destroyed, energy and water consumption was rising, and sowas pollution of all kinds. This environmental destruction has continued, and one important factorhas been the way that buildings are constructed. In fact, energy use in buildings represents about 32percent of all energy use in the United States. In the early years, green builders were a smallminority, and their goals of reducing the environmental impact of buildings were consideredunrealistic. Now, however, the green building movement is growing, as builders have been able totake advantage of new technology and as the costs of this technology have gone down.Environmental building methods are now practical enough to save money for builders and forbuilding owners, even as they reduce damage to the environment. First, green builders try to make use of recycled materials as much as possible. In fact, vastamounts of materials such as steel, cement, and wood are used in construction. Now there arecompanies that specialize in gathering old materials, processing them, and selling them to buildersfor new buildings. States and cities are encouraging these companies, as the reuse of materials alsomeans less waste in dumps. For larger builders or individual homeowners, it is possible to findeverything from steel and cement to doors, windows, sinks, tubs, brick, and hardware. Another way that builders can reduce environmental impact is to reduce the energy requirementsof a building. This can be done in several ways. One is to provide an alternative, non-pollutingsource of energy. The first alternative energy source to be developed was solar power. With solarpanels-wide, flat sheets of special material-it is possible to produce electricity from the rays of thesun. Builders can install solar panels on the roofs of buildings and connect them to cooling orlighting systems. Once the panels are installed, they provide energy at no cost and with nopollution. Another, non-polluting solution for reducing energy use is a technology known asgeothermal heating. To obtain geothermal heat, builders place special pipes below ground, wheretemperatures remain constant all year. In the winter, the earth's natural heat can be collected in thesepipes, and then transferred into the building's heating system. In the summer, heat in the buildingcan be collected and sent to the pipes underground.
