Hydropower as a renewable and sustainable energy resource meeting global energy challenges in a reasonable way

摘要

Central and State Governments in many countries have enacted laws and regulations to promote renewable energy and to encourage sustainable technologies. In doing so, they had to define what they mean by "renewable" and "sustainable", and they had to decide which particular technologies or organization would be eligible for subsidies and tax concessions, and which others would be excluded. Not infrequently, a considerable amount of lobbying would precede the passage of such laws and regulations, and the resulting definitions of "renewable" and "sustainable" are often different than their original meaning.
