Hydropower is generated from water moving in the hydrological cycle, which is driven by solar radiation. It does not reduce water resource and does not use any fuel, which makes it a renewable energy. It prevents greenhouse gas emission and helps reduce global warming. Hydropower also gives many economic benefits. The estimated cost of hydroelectricity in 2040 will be $46.4/mwh, which is lower than the estimated cost on 2022(58.2$/MWh).
About 40 percent of the world’s energy is produced by the “waves”. Coastal cities tend to be well-populated, so lots of people can get use from wave energy plants. A final benefit is that there are a variety of ways to gather it. The biggest advantages of wave power as against most of the other alternative energy sources is that it is easily predictable and can be used
When contrasting proven methods for the creation of energy, wind power stands out definitively as effective and clean for the environment. However, placing wind turbines in strategic locations to maximize the device 's use excludes many regions. Areas without continually strong wind may by consistently sun, therefore, would alternatively use solar panels instead. Regions with many river would presumably favor underwater turbines rather than wind. All previously stated choices, when properly and safely used, create energy from renewable sources.
It will never stop when there is a wind resource and seems to be a long lasting energy resource. In conclusion I think wind energy is the best energy resources to solve the world's pollution problem. It is because......... The advantages of using wind energy are as follows :- (a). Environmental protection and no need to get fossil fuels to generate electricity; (b).
Solar energy Solar energy is a renewable resource which can help us save other resources. Solar energy emits no toxins in the air, significantly reducing harmful air pollution and improving air quality. The environment does not just affect us but it also affects lakes, ocean, rivers, and other things. For example if every houses in new jersey has solar panels it can have an impact of removing two cars from the street. According to the environmental protection agency, using solar electricity to power i million houses would reduce greenhouse gas emission by 4.3 million and its the same thing as removing 850,000 from the street.Solar energy is one of the best sources to create or generate electricity.
We preserve our planet for future generations by looking at the role science is playing to cut down carbon-based energy to move to renewable low-carbon energy to meet our constantly increasing demands of electricity consumption. Green electricity benefits us to produce electricity from sources which would not harm or pollute our environment. For sure, few electricity bases may also have influences but they are much greener than the others. The most suitable energy sources are the renewable energy sources, as they will never expire or run out. (Figueiredo, João Neiva De, 2014) Nuclear energy is number one in the production of electricity.
Hydroelectricity Hydroelectricity is produced in a manner that is not harmful to the surroundings. It is safe, powerful and does not produce any waste. Besides, it is very easy to produce and that makes it the best energy alternative when the electricity demand is high. Water in a reservoir can be released when required, hence the energy is produced with ease. The possibility to control hydroelectric power makes it the solution to less controllable sources of energy.
Gathering energy from waves is a clean and renewable process that poses a huge potential. In addition, different from fossil fuels, creating power from waves creates no harmful byproducts such as gas, waste, and pollution. The energy gathered from waves can be taken directly into electricity-producing machinery and used to power generators and power plants. In today's modern times it is hard to come by a clean source of energy that does not harm the environment. Taking advantage of only the waves no greenhouse gas emissions or water pollutants are created.
As it’s prefix suggests, hydroelectricity is produced by the force of water. This means there is no chance of pollution to the atmosphere like there is with dangerous energy sources like natural gas and coal (energy.gov). This process of obtaining energy is not harmful to the atmosphere, unlike the ways fossil fuels are gathered. Due to the fact that toxic fossil fuels are absent in the process of turning the force of water flow into sustainable energy, hydroelectricity is a source of energy that people should be more aware of. “In addition to a sustainable fuel source, hydropower efforts produce a number of benefits, such as flood control, irrigation, and water supply.” (energy.gov).
The building of dam for hydropower generation is one human activity that impact the water cycle. Change in land use and cooling water for power plants. (geocases2, n.d.). Reducing human impact on the water cycle could change life in a serious way, both for the negative and the positive. One of the activities as mentioned above is damming of lakes for hydroelectricity.
