They can always keep collecting the power. No matter what people may argue about how much coal, natural gas and petroleum remains buried in the Earth, those fossil fuels will run out far earlier than the life of the sun ("Solar Power Vs. Fossil Fuels"). Home owners should invest in solar energy because solar systems have very dependable technology with little maintenance, they offer financial savings and they are better for the environment. Solar systems, also known as solar panels, are built to be very efficient and require very little maintenance. Technology has helped to improve the look and construction of the solar panels.
On the other hand, hydroelectric plants do not release any emissions such as carbon dioxide or sulfur dioxide, both of which increase to global warming and climate change. This is a tremendous advantage over fossil fuel use. Also, there isn't any need to worry about nuclear disasters like there is with the use of nuclear energy. Another renewable energy resource that has a lower amount of environmental impact is solar energy. Solar energy is created and used through the use of photovoltaic cells that collect the suns energy and then convert that energy into a useful form like electricity.
Although renewable energy can be expensive to build, it has less environmental damages in comparison to non-renewable energy. Besides the natural resources such as sun, wind, water and hydrogen, we also have geothermal power, and biofuels as renewable sources. First of all, solar energy is the energy produced when the sun heats the solar panel. Thus, when the sun heat the panels, it produces electricity. Solar power produces energy during the day and can storage energy for the night.
This involves relating the current supplied to the motor, motor shaft rotational speed, motor efficiency, and the power factor as a function of the load of the motor, similar to the figure on page 21 of the Lab Manual. · Develop the friction factor chart for the piping system. This chart shows the relationship between the fanning friction factor and the Reynolds number over a wide range of flow rates, from which the roughness parameter (e/D) for the piping system can be estimated. · Determine the optimal flow rate delivered by the pump. This value is estimated by neglecting all of the friction head losses outside the loop of the piping system.
However, nuclear power is a reliable source of energy because it has no carbon emissions, energy is available at any time, little fuel is needed for a lot of energy, and as time goes on, it is becoming safer and safer. A major advantage of nuclear power is that it does not release any carbon emissions like fossil fuels (“Advantages and Disadvantages of Nuclear Energy”). The burning of fossil fuels releases greenhouse gases, which is what causes global warming. The transition to using fewer resources like these and using more nuclear power for energy will benefit the environment greatly. Arctic environments will not suffer, and ocean levels won’t rise.
Not having to rely on the climate and weather to operate, they can produce large amounts of energy 24/7 while in operation. Power plants take up much less land compared to other green energy sources such as wind and solar power. (NEI, 2013) Some people worry about the waste that nuclear power leaves behind. In relation to the amount of energy that it produces, the toxic waste is minimal. The waste is very small in comparison to waste produced by fossil fuels.
This shows the underutilized capacity of solar energy in attaining sustainable developments. The photovoltaic systems do not release greenhouse gases in the power generation process. Moreover, they can convert sunlight into electricity even in conditions of low solar energy. This proves that solar power can be available for use in domestic or commercial buildings even on cloudy days. In contrast, the indirect conversion of solar energy through CSP techniques involves the generation of heat energy and using the resultant steam to operate power generators (Hirschmann 36).
A common system like this is the solar-wind-diesel hybrid system. These systems work in conditions that both would be used but, maybe not at the same time. For example, “Where wind speeds are low at times and when Sun shines brightest and longest, or when the wind is strong but less sunlight is available” (Salkalachen 1250). This says that when one system is not reliable, the other will cover its mistakes. The “engine generator powered by conventional fuels such as diesel” mentioned earlier is to fill any gaps of power when the two systems are at a low (Salkalachen 1250).
Hydroelectric energy can be used to provide electric power to small towns and cities. Geothermal energy can be used to heat buildings or water and to power turbines to make power. Wind energy can be used to pump water and generate electricity. Solar energy is of the most resourceful sources of alternative energy. It is the most important of the non-conventional sources of energy, because it does not pollute the earth.
The method, conversion of flowing water to electricity, is known as very environmental process because no waste is created during energy generation. Many hydroelectric power plants depend on the same similar basic rule as a historical water wheel. Howe... ... middle of paper ... ...tion or loss of fish habitat, and inundation of wildlife habitat and land in some cases. There could be changes in stream water quality and reservoir in some cases as well. Although both wind power and hydroelectric power have some disadvantages, I believe wind power is more useful than hydroelectric power because wind power will not produce any pollutants while hydroelectric power produces few minimal pollution.
