Answer: c. Scientists mistakenly thought pollution reflected sunlight and heat rather than absorbed it.
Scientist mistakenly thought pollution reflected sunlight and heat rather than absorbed it. This best explains that air pollution that was once blamed for global cooling is now considered responsible for global warming because the carbon dioxide from greenhouse effect will reflect the sunlight and will split the UV rays and prevent them to enter inside the earth. But carbon dioxide is responsible for increasing the global temperatures.
Wind power:
Advantages:
-Using wind as a source of power is very cost-effective. This is method is fuel free and the electricity harvested from wind farms is sold at a fixed price over a long period of time.
-Wind power is a clean fuel source. Using wind as a source of power prevents air pollution unlike power plants that mostly rely on fossil fuels which releases toxins into the hair causing both environmental and health problems.
-Wind power is a sustainable source of power since nothing can really stop it from being produced. Since this source of power relies on air, as long as there is air, energy can be harvested.
Disadvantages:
-Wind turbines are usually built in rural areas due to the size of them and the amount of space needed to build them. Because of this, they aren’t usually close to cities or remote locations where the energy harvested from them is most needed.
-Wind turbines can harmfully impact nature. Because of their height and size, many birds and other flying animals end up getting killed by the spinning blades connected to the turbine.
-Locations to build wind turbines may be hard to get due to competition with other things that may be of more importance on the land compared to wind farms.
