Pros and Cons of Wind Power

Tidal power is also relatively prosperous at low speeds, in contrast to wind power. Moreover, technological advances in the industry will only drive cheaper and more sustainable tidal power solutions. One of our assets, CorPower, is challenging how the industry thinks about wave energy by using principles of the human heart. Through its wave energy converter, the company is able to deliver five times higher wave energy absorption than other technologies. Tidal barrages are long concrete structures usually built across river estuaries. The barrages have tunnels along them containing turbines, which are turned when water on one side flows through the barrage to the other side.

These dam-like structures are said to have a lifespan of around years. The La Rance in France, for example, has been operational since and continues to generate significant amounts of electricity each year. Wind turbines and solar panels generally come with a warranty of 20 to 25 years, and while some solar cells have reached the year mark, they typically degenerate at a pace of 0. The longer lifespan of tidal power makes it much more cost-competitive in the long run. Even nuclear power plants do not last this long. For example, the new Hinckley Point C nuclear plant planned to be built in Somerset, UK, is estimated to provide power for around 60 years, once completed, according to a BBC report. Disadvantages of tidal energy: lack of research While the true effects of tidal barrages and turbines on the marine environment have not been fully explored , there has been some research into how barrages manipulate ocean levels and can have similar negative effects as hydroelectric power.

The Atlantis-manufactured turbine studied was able to turn off when larger mammals approached. However, there is still a need for further research. We have no concrete proof, just theories based on existing knowledge and computer modelling. Fellow PNNL marine ecologist Jeff Ward said the organisation was observing how EMFs damage the ability of juvenile Coho salmon to recognise and evade predators, or the negative impact on Dungeness crabs to detect odours through their antennules. They are also observing whether sea life is attracted or repelled by EMFs in general.

Particular species that are susceptible to EMFs are sharks, skates, rays, crustaceans, whales, dolphins, bony fish, and marine turtles. Many of these animals use natural magnetic fields to navigate their environment. Another experiment found that benthic elasmobranchs — which includes sharks, rays and skates — were attracted to a source of EMF emitted from a subsea umbilical.

Again, there was no conclusive evidence of any cumulative, detrimental effects. While long-term generation costs are relatively good compared to other renewable energy systems, the initial construction cost makes investing in tidal energy a particularly risky venture. Firstly, installing a tidal system is technologically challenging.

Manufacturers are competing against the moving ocean, and the equipment and technical knowledge needed to successfully construct the system is typically very expensive, especially compared to a wind or solar farm. The wind turbines harmlessly generate electricity from wind passing by. Wind energy is far more ecofriendly than the burning of fossil fuels for electricity. Currently, the United States, along with other countries, remains dependent on fossil fuels imported from unstable and unreliable nations. Wind power has the ability to free the US from the figurative economic bondage of fossil fuels. Once turbines and energy centers have been installed, the cost of maintaining turbines and generating wind power is next to nothing.

Another advantage of wind power is the ability to place turbines wherever necessary. After performing research and finding areas that have adequate wind, experts may place the turbines in desired areas. These areas are usually unpopulated offshore wind turbines, for example. The two major disadvantages of wind power include initial cost and technology immaturity. Firstly, constructing turbines and wind facilities is extremely expensive. The second disadvantage is technology immaturity. Offshore wind energy produces more energy than onshore wind energy, but costs much more to establish. The primary costs of wind turbines include construction and maintenance.

Therefore, one may argue that implementation of wind energy must be delayed until technological advancements are made. Other disadvantages include:. Aesthetic impact: Many people are concerned with the visual effects that wind turbines have on the beautiful scenery of nature. They believe that giant wind turbines distract viewers from the beautiful surroundings. Wildlife: Wind turbines may be dangerous to flying animals.

Many birds and bats have been killed by flying into the rotors.

Natural gas must be released and transported. Wind Technology. Although the wind Our Dirty Love Affair With Trash Summary Illegal Immigrants Citizens Essay Advantages And Disadvantages Of Multicultural Society will never run out, wind speed does change.
