Pros And Cons Of Hydropower

Moving into the next renewable energy, there is a big advantage that hydroelectric power is that hydropower dams is a huge renewable resource and using water to create electricity has no carbon footprint. As well as there is less pollution from it overall. There are many advantages but there are two distinct disadvantages, one of them being the cost to build an electric power station. The cost

From late 1960’s the demand of electricity started to increase and since then, the growth is gradually increasing until now. The population in the province has been growing three million per year since 1965 and it is predicted to keep growing in the future. The population growth causes scarcity of any resource. The supply of electricity from 1960’s till now was reasonably sufficient however, in the near future it has been predicted that the demand increases are growing faster than BC hydro can supply. Therefore, BC needs some other way to increase the supply of electricity and the substitute that BC hydro found is hydroelectricity (Site

The economic and environmental issue surrounding Hydroelectric is because it is very expensive and damages ecosystems. (Campus France)

Some cons that hydropower has include; Environmental impact, Displaced people, and Accidents. The environmental impact would be before producing hydropower, it is necessary to build a dam, changing water levels and flooding large areas. It is also necessary to build roads and power lines. This has a strong impact on wildlife and the ecosystem. When building a dam the construction of a large dam often requires that entire towns move out of the area. In the construction of the Three Gorges Dam it is estimated than 1.2 million people were displaced. lastly , in the past old dams often suffered breaches which led to floods and

Hydropower represents 19 percent of the world 's total electricity production and has several distinct advantages compared to other traditional power-producing methods. Hydropower plays a major role in the reduction of greenhouse gas emissions since it does not require any fuel burning, potential energy (i.e. water) supply

Is hydropower the liberator of America? Unlike fossil fuels, hydropower allows for renewable resources to be taken advantage of, while producing energy. This cost effective, environmentally friendly, renewable, and safe, energy source entitled hydropower can replace fossil fuels.

“In some areas of the world, hydroelectric power is the main source of electricity' In South and Central… power. Norway gets 95 percent of its electricity and over 50 percent of all its energy from hydroelectricity. Canada gets 59 percent and the United States gets about 8 percent of its electricity from hydroelectric plants” (Enger and Smith 222). With the development of efforts being made to benefit the environment, why wouldn’t anyone agree to switch to renewable energy? Hydropower has been used in the past to power a number of machines and it worked

Hydro-electric dams are not an environmentally friendly form of producing energy because is will cause people to relocate. In Canada, there was a dam approved to be built in 1958 which caused over 6,500 people to relocate. Hydro-electric dams need large amounts of water in order for the dams to meet the electricity required. Therefore, they need large reservoirs. These big reservoirs and high amounts of water decreases the land area for people and animals to live in. In conclusion, hydro-electric dams are not an environmentally positive form of generating energy, it will cause people to relocate.

5. Water energy (Hydroelectric power) plants use water in a different way, converting the energy in falling water into electricity by passing it through turbines. Fuel Extraction and Production – Water is a critical resource for the drilling and mining of natural gas, coal, oil, and uranium. Pros: 1. Green 2. Reliable. 3. Flexible Cons: 1. Droughts 2. Limited Reservoirs 3. Expensive

Its powers most of the building like homes, hospitals, schools, factories and etc. Hydroelectricity comes in a human cost. The huge damn that required for hydroelectric energy projects create a reservoir that floods an entire valley. Like homes, communities, and towns that may have to relocate as a dam construction begins. However, the projects to make a hydroelectric power generator has forced more than millions of people to relocate. Lifestyles were disputed. We don’t have to burn fuels to cause pollution… pollution free. Hydroelectric developments don’t generate toxic by-products. With an average lifetime of 50 to 100 years, hydroelectricity developments are a long term. It can easily be upgraded to incorporate more recent technologies and have very low operating and maintenance cost. Dams are designed to last decades and so can so contribute to the generation of electricity for many years and decades. Hydroelectricity is the cheapest way to provide energy. Once a dam is constructed, electricity can be produced at a constant rate. Large dams can be useful for flood control. It’s a clean energy source. It does not produce green house gases. When a hydroelectricity water storage dam is built, the water can be used as drinking water and also a recreational purpose such as fishing and boating. Dams saves and reserves water so that it is not wasted into oceans and seas. Controllable source of

By using this, we would already have a renewable resource that covers 70% of Earth. I know that we have several dams built in my state. We can use the dams to run water through a turbine, which uses a generator to convert it into energy. Water is cheap to use since we have a such high demand of it, however, we shouldn’t overuse water. We have the water cycle, but that doesn’t mean if we overuse water that it’ll always be here. Also, most of today's water is highly polluted. That would cause an issue. It would always be available no matter the weather. Water is always

Hydropower is a very big provider of power in Costa Rica because it is so efficient the water never stops so that power it is providing Costa Rica with 80.27% of their energy. In Costa Rica they built a dam and the water has to get thru the dam by using the water pressure from the reservoir, it passes through the dam and spins the blades of a giant generator which makes electricity. Hydropower is ran by water so it's clean and won't pollute the environment, unlike power plants that burn fossil fuels, for example coal, and natural gas.

Hydroelectric power plant is one of the major power plants all over the world in order to create electricity. It is also one of the best renewable energy sources on the planet earth. In ranking, Canada is the third largest country to produce hydroelectricity power. The efficiency of this power source is 90% and this is very impressive as the percentage of efficiency is very high. Hydro power plants generate 24% of the world’s electricity. More than 1 billion people are associated with hydro power plants as they use the power supply from hydro power plants.

Brazil is the third largest consumer of electricity in the Western Hemisphere and the ninth largest in the world. In 2011, of the 531 trillion watt hours of electric power generated, hydropower accounted for 424 trillion watt hours, approximately a staggering 80%. Brazil undoubtedly has extremely high reliance on hydropower. However, due to the large size of hydroelectric dams, the construction of dams lowering biodiversity in the Amazon Rainforest, and the unstable climate of Brazil, the hydroelectric power across Brazil is environmentally ineffective.

As you most likely know, the Mekong river is quite essential to human and animal life in its river basin. There are more than a few ways that us humans are dependent on the Mekong river. Some of these are food, water and increasingly, electricity. All of the previously mentioned needs seem important but one clashes with the others. Hydropower is à renewable energy source which is rising in popularity. Since hydropower is à renewable energy source it is not believed to be harmful to the environment. According to an expert on the topic, Professor Philip Hirsch, Hydropower is Laos’ gateway to getting rich. As stated by Xaypaseuth Phomsoupha, building these dams helps with providing à better life for the Lao population. But the disadvantages
