Alternative Energy Sources and Green Technology

Abstract

This paper presents a review of the green technologies and processes for the development of renewable energy resources. Renewable energy options show a lot of potential for fulfilling the world's energy and development demands. This promise is especially compelling in emerging nations, where many areas have yet to commit to fossil fuel supremacy. Solar photovoltaic and solar thermal technologies are especially helpful for supplying the two billion people living in rural regions who do not have access to power from the grid. Biomass energy is appealing because it makes use of locally accessible agricultural waste. Small hydroelectric resources and wind energy are also developed technologies that are well suited to develop countries. Renewable energy sources are significantly more cost-effective than traditional energy sources, particularly when the expenses of acquiring, maintaining, and running centralized power plants, as well as the costs of pollution remediation, are avoided. However, a slew of economic, societal, and legal roadblocks stand in the way of these renewable resources attaining their full potential.
