Advantages and disadvantages of wind energy pdf

Wind, that is moving air, possesses some kinetic energy due to its high speed. Wind is a result of the solar energy, as heating of land results in movement of air. The most common application of wind could probably be kite flying! Or even paragliding, sail boats etc. Requires a lot of space?

Loud noise? Can spoil the landscape? Needs specific conditions speed of wind? Can't be utilized all the time? Storage of electricity can be difficult only in batteries or as thermal energy in water?

Advantages of Wind Power. Wind power is cost-effective. Land-based utility-scale wind is one of the lowest-priced energy sources available today, costing 1—2 cents per kilowatt-hour after the production tax credit. Because the electricity from wind farms is sold at a fixed price over a long period of time e.

Wind creates jobs. The U. According to the Wind Vision Report , wind has the potential to support more than , jobs in manufacturing, installation, maintenance, and supporting services by Wind enables U. The United States has a vast domestic resources and a highly-skilled workforce, and can compete globally in the clean energy economy. It's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas, which emit particulate matter, nitrogen oxides, and sulfur dioxide—causing human health problems and economic damages.

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.

In coclusion, when using renewable energy sources, harmful gases such as CO2 and harmful waste do not come out to the nature. As a result, CO2 emissions are very high in energy production. However, solar energy, renewable energy sources, wind energy, biomass energy, hydropower and geothermal energy and electricity generation are low levels of CO2 emissions that can be neglected.

Therefore, one of the greatest advantages of renewable energy is that it is an environmentally friendly energy source. But that is not the case for renewable energy.

Because, in order to use wind energy, mechanical energy is used. There is no waste due to the use of motion energy. The same is true of solar energy. When using solar energy, no fuel is used, and because the fuel is not used, it does not generate waste. Only packaging wastes may arise during the installation phase of renewable energy plants. Packaging waste is collected by many municipalities with their own teams. That is why renewable energy is one of the environmental benefits of not generating waste.

But there are also disadvantages of renewable energy. But these disadvantages are not as much as the disadvantages of fossil fuels. Unfortunately, the renewable energy technologies used low. Fossil fuels are still more energy-intensive than renewable energy. The disadvantages of renewable energy can be said to be less energy production and less consumption.

Because, exactly solar energy produce less energy in large area. Because, about 1 kW photovoltaic module has 6,4 square meters in an area. So that solar energy is not suitable for small countries because it takes up a large area. Moreover, photovoltaic modules do not fit into the roof of large buildings. To sum up, renewable energy sources produce less energy in a big area so that its an important disadvantages of renewable energy sources.

But for renewable energy production, the outdoor environment must be at the optimum level. For example, to generate electricity with wind turbines, optimum wind conditions must be established. The speed of the wind should not be too fast, not too fast.

Otherwise, it can not be used in the wind. Because other cities do not have the desired wind conditions. But above mentioned cities also have the desired wind speed and level. The same applies to solar energy. We see that these cities have an annual production capacity of to kWh per square meter.

But when we look at our Black Sea illusions like Kastamonu and Sinop, we see that the average energy production potential per square meter is kWh. Also germany has solar energy potential per square meter is kWh. Another source of energy among renewable energy sources is wave energy.
