Discuss the advantages and disadvantages of using wind power for large-scale energy production.

Advantages:

Clean and environmentally friendly fuel source - It doesn’t pollute air like power plant relying on combustion of fossil fuel. It does not produce atmospheric emissions that cause acid rain or green house gases (carbon dioxide (CO2) or methane (CH4)). Noise and visual pollution are both environmental factors, but they don’t have a negative effect on the earth, water table or the quality of the air we breatheRenewable & Sustainable - Winds are caused by heating of atmosphere by the sun, earth surface irregularities and the rotation of the earthCost effective - It is completely free, no market for demand and supplyJob Creation - Creates many jobs for manufacturers, installation and maintenance workers and energy consultants. According to the Wind Vision Report, wind has the potential to support more than 600,000 jobs in manufacturing, installation, maintenance, and supporting services by 2050Industrial and Domestic Installation – Wind turbines can be built on existing farms or ranches where most of the best wind sites are found. Wind turbines uses only a fraction of the land which causes no trouble in work for the farmers and rancher, providing landowners with additional income paid by the owners of the wind power plants. Many landowners opt to install smaller, less powerful wind turbines in order to provide part of a domestic electricity supply

Disadvantages:

Fluctuation of wind and good wind sites – Wind energy has a drawback that it is not a constant energy source. Although wind energy is sustainable and will never run out, the wind isn’t always blowingNoise and aesthetic pollution – Wind turbines generate noise and visual pollutionNot a profitable use of land - Alternative uses of the land might be more highly valuedThreat to wildlife - Birds have been killed

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
