Renewable energy systems (wind and hydraulic) - Essay Example

hellip; The writer of this essay explains that the use of alternative, sustainable sources of energy such as wind, solar, hydro-electric and geothermal is essential for the future of mankind.... These “wind farms” provide power directly to the electric grid.... (“Energy Basics,” 2011) Horizontal axis turbines consist of two or three blades attached to a rotor that is placed on tall tower structure facing either away from or into the prevailing wind current....

renewable energy.... renewable energy.... renewable energy.... "Design, simulation, and testing of a novel hydraulic power take-off system for the Pelamis wave energy converter".... wind waves can be regarded as a concentrated form of solar energy, and so have more power density.... Here, the energy is transformed from solar energy to wind energy, and then to wave energy.... A wave power device can produce or generate power up to 90% of the time, unlike solar and wind which generate ~20-30% of the time....

Methane is a natural gas which migrates to aquifers when there is a combination of horizontal drilling and hydraulic fracturing.... Economists know that a big investment is made through fracking than renewable energy.... The department should understand about the hydraulic fracturing or fracking.... In short the oil industry should increase its plans to increase oil production with hydraulic fracturing to increase oil recovery even if it's threatening the communities' air and drinking water....

One of the ways is through the use of renewable resources such as wind and hydraulic power.... Unlike Chernobyl, the precipitant to the nuclear disaster resulted in an earthquake, which damaged the systems.... The earthquake damaged the safety systems and is what lead to the reactor breach.... One area that has become an increasingly globalized problem is the… The most popular and most used way of generating energy throughout the world is through burning fossil fuels....

Finally, fracking offers promise as the bridge between energy systems based on carbon from the past and a future that is greener and cleaner.... Finally, the process may also end up solidifying the United States reliance on fossil fuels, thus relegating renewable energy research to the background.... Fracking, is synonymously acknowledged as hydraulic fracturing, involves the drilling of shale gas from thousands of feet under the surface of the earth, while also pumping at high pressure millions of chemicals and water additives into these drilled wells (Hillstrom 23)....

These include solar, wind, and hydraulic energy systems.... Brazil has subsidized the equipment required for the renewable energy installations such as the solar panels and wind turbines in order to encourage further use of renewable energy.... This has been done by removing or reducing the bureaucracy that is involved in getting work permits,… The government has been at the forefront in offering incentives to the investors in terms of loans or free tax zones to encourage investment (Diniz, 2014). Brazil is one of the leading green energy producers in Case Study on Brazil The Brazilian government has worked efficiently to ensure that it has policies that are attractive to both local and foreign investors, who are willing to invest in the country....

The same principle applies to wind and water where the energy can be converted into another form of energy to become useful.... wind power – is an energy sourced from the wind through windmills.... Again, its downside is that it is expensive to set up wind mills and convert it to electricity.... Second Law – “stipulates that the total entropy of a… ystem plus its environment can not decrease; it can remain constant for a reversible process but must always increase for an irreversible process” (NASA, nd). Understanding the laws of thermodynamic can lead to conversion and energy efficiency by the converting one form For example, the energy coming from the sun which is useless in our industry can be converted to become electricity and be used as a source of energy to light up our homes and power our industries....

Fossil fuel is considered to be a convenient resource to attain energy and the modern world is looking forward to utilizing the alternative resources like wind, tidal, solar geothermal, hydro, etc.... The purpose of this assignment is to investigate the environmental aspects of applying wave and tidal energy as a source of alternative energy....  … The law of conservation of energy states, “energy can neither be created nor it can be destroyed, it can be transformed from one form to another” (Denecke 2006)....
