Pros And Cons Of Hydroelectric Power

First, the use of hydro energy resource, which is still debatable if it’s renewable or nonrenewable, cannot always be suitable for flat or dry regions and in areas where natural disasters occur. So counties with natural disasters or regions that are not suited is most likely not going to have a hydropower, as mentioned in (Marmulla, 2001, p. 55), dams are unnatural effecting species like fish causing migrations because of habitat loss. This can lead to extinction of species, affecting many ecosystems, since the fish starts to migrate to different areas changing the population balance. For example, Nicola, Elvira,

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

Hydropower is

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

Even though it provides the people with around $7 million worth of hydroelectricity each year, the negatives outweigh the positives.

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

Dams are used to generate hydropower by releasing the water to move the turbine that generates the power. Hydropower is a big industry in the United State it is responsible for most of the United States renewable energy resources. Dams are made for the water storage in areas where water is not easily accessible. The storing of water allows communities to have a reserve water supply in case of a drought or water shortage. In places like California that have been in a drought for years would not be able to survive without the Dams and reservoirs to keep a water supply. Without this water, the cities would have to move to a climate with more available

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

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.

As we all can see all energy sources have drawbacks even the clean hydropower, some of the advantages of clean hydropower energy are as follow: Nuclear power generation does emit relatively low amounts of carbon dioxide (CO2).

Hydroelectric power tends to upset the ecosystems in rivers and lakes. It affects the fish and wild life population. Nuclear energy is a very controversial subject. Although it produces high quantities of power with relative efficiency, it is very hard to dispose of the waste. While wind and solar power have no waste products, they require enormous amounts of land

Energy is a critical component for every economy and society around the world. Energy is divided into two groups, nonrenewable (coal, oil, natural gas, and nuclear) with a finite amount found around the globe and renewable (hydro, tidal, solar, wind, geothermal, and biomass) that are constantly being replenished so that they will never run out (Green Energy Choice, 2011). The international economic impact of renewable energy is explored by examining subsidies, strategic policies, and comparative advantage of renewable energy.

Hydroelectric energy: Pros- it’s renewable, which means that we cannot use it up, but it is a limited power plants. They are also very reliable; flexible which means it can adjust to water flow or output of electricity Cons- it’s too expensive, drought, and limited reservoirs (power plants), but they do not require a lot of workers, they say it’s about 30 major power plants that’s expected to generate more than 2.00 MW under the construction. Oil: Pros- No other energy source can move vehicles with greater speed at longer distances than oil, it’s easy to handle, store and handle, also its easier to get from the ground than coal. Cons- it pollutes the atmosphere, oil spills onshore and in the ocean, drilling for oil may affect ocean and terrestrial habitats. What is the problem with nuclear waste, and what is Yucca Mountain? Well, the problem with nuclear waste is that its sometimes called spent fuel which is dangerously radioactive, and stays for about a thousand years. When it is
