Alternative energy is a term for any nontraditional energy form, source, or technology differing from the current popular forms, sources, or technologies. Today, it is generally used in the context of an alternative to energy deriving from popular fossil fuels and thus includes energy derived from such environmentally preferred sources as solar, water power, biomass, wind, geothermal, ocean thermal, wave action, and tidal action.

The term alternative energy also is used for energy derived from sources and technologies that do not involve the depletion of natural resources or significant harm to the environment. As such, it is used synonymously with "renewable energy" and "green power." While by most definitions there is substantial overlap between energy forms, sources, and technologies that fit into these three categories, and alternative energy often is applied to energy without undesirable environmental consequences or with lessened environmental impact, the three terms also have been delineated differently.
The Tāj Mahal is a mausoleum located in Agra, India. The Mughal emperor Shāh Jahān commissioned it as the final resting place for his favorite wife, Mumtaz Mahal. Construction began in 1632 and was completed in 1648. It is considered by many to be the finest example of Mughal architecture, a style that combines elements of Persian and Indian styles. While the white domed marble mausoleum is the most familiar part of the monument, the Taj Mahal is actually an integrated complex of structures.
Shah Jahan intended the Taj Mahal to be acclaimed by the entire world, and since its construction the building has been the source of an admiration that has transcended cultures and geography. Personal and emotional responses to the building have consistently eclipsed the scholastic appraisals of the monument. The poet Rabindranath Tagore, a Nobel laureate, called Taj Mahal "a drop of tear on the cheek of history."
The Taj Mahal is considered one of the Seven Wonders of the Modern World and was listed as a UNESCO World Heritage Site in 1983.
