Is Tidal Energy Great Potential For Future Power Or Tidal Energy?

Water turbines are near the oldest ways to run power without using fossil fuels. The new age had turned these into hydro turbines that generally reside in dams. These machines take similar shape to wind turbines. Hidden in the base of a dam, there is a very large turbine that, in a simple explanation, when water runs through it spins. With the energy used by the spinning turbo it is turned into different power sources that are stored into power cells. Way back in time, this idea was used in power mills. Those old spinning wheels on the side of houses that rotate with water pressure. The first power plant was constructed in 1879 at Niagara Falls, Canada. In the United States the first plant was in 1882 in Wisconsin. These extravagant machines seemed marvelous, but that is no longer the outcome. The current age hydroelectricity dams are currently being shut down for harmful aspects triggered from the giant production. Causing an environmental failure to marine life and habitats all around. The possible outcomes are: changing the oxygen levels in the water that cause organisms to perish; fluctuating water levels that cause different

2. Wind power is generating electricity by collecting wind, and it saves energy in the world.

Generating power with gas (as an alternative to coal) and increasing the use of renewable energy sources also seem like very suitable options [9]. Additionally, power generation with the use of wind and tidal energy proves a very convenient alternative to nuclear power generation in London and the UK in general. These sources can deliver twice the amount of electricity as new-age nuclear reactors and would require less time to be implemented, thus the convenience [12].

2. tidal currents that pass through narrow channels can be used to turn underwater pivoting turbines, which produce energy. potential for usable tidal energy increases with an increase in tidal range because a higher tidal range means more water moving in and out of the turbine system.

Hydropower is a renewable resource that is clean, affordable and durable. This resource is clean due to the way you gather the energy from it. hydroelectric and coal-fired power plants produce electricity in a similar way. In both cases a power source is used to turn a propeller piece called a turbine, which then turns a metal shaft in an electric generator (the motor that produces electricity). A coal-fired power plant uses steam to turn the turbine blades; whereas a hydroelectric

Wind turbines are another common way to power things. They are usually made to power a city and many are needed for a lot of energy to be created at once. Wind turbines are made to be very tall because that the higher up you go, the windier it gets.

When the wind is blowing on wind turbines it produces electric power, Fans are old techniques used in the mills and then the water pump, but now it has developed the technology and has become used for electric power production.

“Tidal power generates energy from the tides moving in and out…wave power generates energy from the rise and fall of waves.” (Cunningham.) Capturing the ocean’s movement is a great form of renewable energy with waves never running out and that they are available in many areas of the world. There will be no byproducts that will be harmful or will pollute the environment, and to receive the energy there can be many different gathering techniques. In retrospect towards marine growth, submerged wave energy converters will make “safe havens” because they will become artificial reefs with a closed off surface areas. “They insist that if all 28,000 miles of U. S. roadways are covered in these solar cells, it would generate three times more power…” (Cunningham). The hexagonal solar panels would be able to make more productive areas such as a solar parking lot, additionally paying for themselves and power other homes or businesses. In order to improve the safety of every community, there would be heating elements to keep roads snow/ice free, and LEDs to make road lines. There is little maintenance to ensure that the solar panels are in working order, and they are a silent producer of energy. When compared to burning fossil fuels in power stations, solar energy stands out by the fact that it saves money and gives energy security in households. “Human waste is taken to a treatment plant…methanogens go to work…methane is produced as a byproduct.” (Cunningham). Currently, over 200 millions tons of human waste go untreated, and once they get into the clean water, many die from diseases in contact with the fecal matter. When methane is burned as electricity, there would be a decrease in treating water and disposing

Converting tides into electricity requires water, and something influencing the gravitational potential energy. The earth’s surface is approximately seventy percent water, and the moon still affects earth, so that indicates that tidal energy has efficiency in the long term. Ocean currents are approximately eight hundred times denser than air currents, which means that tidal turbines generate more energy and produce more electricity than air turbines due to the greater force applied to the

Hydroelectric is a form of energy it is a renewable resource. Hydroelectricity is the most important and widely used renewable source of energy. Hydroelectric relies on water, which is clean and renewable energy source. Renewable energy comes from natural resources. Non-Renewable energy source includes coal, oil and natural gas. Water is renewable because water continually recycles itself. To harness energy from flowing water, the water must be controlled; a large reservoir is created, usually by damming a river to create an artificial lake or reservoir. Water is channeled through tunnels in the dam. The energy of water flowing through the dam causes the turbines to turn and make the

This is why tidal energy generation would be much more efficient than hydroelectricity energy generation in Nova Scotia because there are not many strong flowing rivers. The Electric Power Research Institute (EPRI) located in California stated that the Bay of Fundy had potential to be the best site in North America for tidal energy generation. I believe that Nova Scotia should take advantage of these tides and use them as an important resource for our province. After the costs of the infrastructure and maintenance, tidal energy generation would be essentially free, as the tides move on their own. A lot of energy can be created through tides, as tidal power is very sensitive to speed. The amount of energy formed is the cube of the speed of the water. For example, if the speed of the flowing water doubles, the energy output is eight times greater. This energy can be formed from both the change in the height of tides, which is potential energy, and the flow of the water, which is kinetic energy.. As of now, the main technologies used are in-stream devices, barrages, and tidal lagoons. I think the best solution for Nova Scotia right now would be to build a tidal lagoon in the bay of Fundy. A tidal lagoon is like a barrage (which is essentially a dam built across the whole estuary) but it can be built as a self contained structure. This makes the cost much lower and they can also continuously generate, unlike a

Humans have made significant discoveries in utilizing the countless benefits of water, one of the most important being the ability to use water to perform work. This is the concept of hydropower. Hydropower is using the energy of moving water to create power. This clean and renewable method of power generation is used all throughout the globe, and accounts for a small percentage of global electricity demand. Hydropower hasn’t always existed as the large scale dams that are abundant today. Hydropower technologies have been slowly evolving for many centuries.

For renewable sources of energy it is the most reliable even though it is variable. Different power generation methods have finite resources that will eventually run out. Other renewable energy resources while powerful are either unreliable such as wind are not always available such as solar energy. Through the use of dams we can store water to be used when needed to supply the demand caused by energy consumption. Using gravity water is allowed to flow through a turbine causing a generator to make electricity. When demand is low the water can be pumped back up into the containing reservoir to make another hydroelectric head. This process can just be continued creating a reliable capacity of energy. In the use of tidal power generation electricity comes in and out with the tide. There is a small marginal effect on the environment because no emission or hazardous waste is being made. While most prime locations for traditional hydroelectric power plants are already taken, there are plenty of locations to be used for tidal power generation. Once the technology to build underwater structures that are able to last against the harsh waves is more manageable there will be plenty of new location ready to be taken throughout the ocean. These generation plants will just be using water and gravity to supply power to meet the ever growing demand of the population. Using water to it full advantage in every facet possible from traditional hydroelectric pumped storage, run of the water types, tidal barrage using shoreline bays and tidal current using the oceans current will make it the greatest resource on

Offshore wind power has become a need of the hour in renewable energy production due to the rising prices of oil and continually increasing demand for a separate energy sector. Offshore wind has the prospective to deliver at least four times the current U.S. demand of energy, as per mentioned by the Global Wind Energy Council. However, there are many challenges and advantages that are significant for us to comprehend.

The SAARC region with over a billion populations is contiguous to the Indian Ocean, Bay of Bengal and the Arabian Sea. Utilization of ocean resources for power generation such as tidal, thermal solar and wind for energy, along with other green technologies like seaweed farming and sustainable fisheries for food would need to be incorporated in a broad framework for the region. Development of ocean-based energy systems can be integrated with early warning networks linked by satellite which can give a few hours to days warning to help mitigate the severity of natural disasters on human life. . Some of the calamities of note have been the Tsunami of 2004, Bangladesh and Orissa floods, earthquakes in Nepal and Pakistan, and recent inundation of Chennai due to weather and bad flood management. A SAARC comprehensive Framework on disaster management was formulated in alignment with the Hyogo Framework (2005-2015). In addition to the broad objectives of disaster management and cooperation in the Indian Ocean and surrounding regions, impeding disasters due to climate change need to be anticipated. Ocean energy systems are still in their infancy, while ocean
