CHAPTER ONE INTRODUCTION 1.1 Background Hydropower has been recognized as a sustainable source of energy with almost zero input cost. Its benefits are that it is none polluting in the sense that it releases no heat or noxious gases it has low operating and maintenance cost‚ its technology offer reliable and flexible operation and hydropower stations have increased efficiencies along with long life. Nepal’s huge potential in hydropower is still untapped. Though Nepal has not yet been able to

Electricity has become the main sources of domestic energy in Australia over the last 200 years and played an important role in today’s society‚ industry . In the early time when the British started to settle in Australia‚ firewood was the most important fuel. In 1831‚ Michael Faraday put forward the electromagnetic induction‚ which led to the development of electric generators and made the large amount of electricity supply become possible. After 1879 when the perfect light globe was designed

WATER RESOURCES The sources of water that are useful to human life are called water resources. Uses of water include agricultural‚ industrial‚ household and recreational activities. The majority of human uses require fresh water. 97 percent of the water on the Earth is salt water and only 3 percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater‚ with only a small fraction present above

The Democratic Republic of the Congo has been exhausting its natural resources in the past decade‚ but with a few economic and priority changes‚ it is possible for the country to promote sustainability‚ increase their wealth and help the Congolese citizens simultaneously. The Democratic Republic of the Congo (or DRC for short) currently is at war‚ in short‚ rebel groups are fighting to take the natural wealth hidden in the DRC like gold‚ diamonds‚ colbolt‚ and other precious elements. The war is

PRESERVING NATURE VS. RESHAPING NATURE Critical analysis of recent floods in Uttarakhand ______________________________________________________________________________ “The environmentalist goal of ‘preserving nature’ unavoidably conflicts with the requirements of human life: Man ’s basic means of survival is to reshape nature to serve his ends‚ to take the raw materials of his environment and use them to produce values. This requires "touching" nature‚ not leaving it untouched” ____

this process produces 24% of the worldwide energy! That supplies 1 billion people. Together‚ all the plants produce 675.000 megawatts of energy- that’s 3.6 billion barrels of oil. Most great inventions succeed‚ and this one definitely has! Hydroelectricity is completely green and safe! The machine itself sets off no pollution at all. It doesn’t need to be powered by any type of fuel (other than water‚ of course) which makes it nice not to have to depend on the ever-changing rates of oil. In comparison

In its various forms‚ it derives directly from the sun‚ or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar‚ wind‚ ocean‚ hydropower‚ biomass‚ geothermal resources‚ and biofuels and hydrogen derived from renewable

it comes at a price since the tour boats release sewage into the water (Min) and that is a primary pollutant of the reservoir. Fertilizers and sewage are common pollutants but the third pollutant comes as a surprise since most people believe hydroelectricity to be clean energy and that is certainly not the case. A major problem with hydroelectric dams in general is that they are not the clean energy that everyone believes them to be. They produce significant amounts of greenhouse gas emissions

Nuclear Energy There are many advantages and disadvantages of using nuclear power. Nuclear power is said to prevent power outages that happen in areas without nuclear power. For an example‚ if we were using hydroelectricity and the dam suddenly malfunctions‚ then we won’t have electricity until someone fixes the dam‚ and that would be difficult if it happened in the middle of the night. However‚ on the other hand‚ nuclear power is also considered toxic and it pollutes the Earth with harmful and
