This project paper studies the potential of hydroelectric energy as a way to effectively generate, use and store renewable energy through the clean gravitational potential energy of stored water. Nuclear and coal fired plants could do change power output to achieve demand but at extremely high maintenance cost. Nuclear plants also being a good source of continuous energy has a high chance of posing hazard to the environment. Coal and fossil fuel fired power plants on the other hand cannot be depended on because the source will diminish someday. Therefore, alternative methods have to be explored in order to find a renewable and sustainable energy for the future generations. This project paper will study the benefits of hydroelectric energy as a potential and important energy source for a sustainable future.

INTRODUCTION

1.0 Hydropower
Hydropower is a renewable energy source based on the natural water cycle. Hydropower is the most mature, reliable and cost-effective renewable power generation technology available. Hydropower schemes often have significant flexibility in their design and can be designed to meet base-load demands with relatively high capacity factors, or have higher installed capacities and a lower capacity factor, but meet a much larger share of peak demand. Hydropower is the largest renewable energy source, and it produces around 16 % of the world’s electricity and over four-fifths of the world’s renewable electricity. Currently, more than 25 countries in the world depend on hydropower for 90 % of their electricity supply (99.3 % in Norway), and 12 countries are 100 % reliant on hydro. Hydro produces the bulk of electricity in 65 countries and plays some role in more than 150 countries. Canada, China and the United States are the countries which have the largest hydropower generation capacity. Hydropower is the most flexible source of power generation available and is capable of responding to demand...
