<h2>Answer</h2>
My Answer would be Option B.
Explanation:
nuclear energy protects air quality by producing massive amounts of carbon-free electricity.
Thermal energy from nuclear reactors may also be used to decarbonize other energy-intensive sectors such as transportation – the largest contributor to carbon pollution.
Answer:
Wind energy
An ideal source of energy needs to be reliable, cost effective, safe and must lead to almost zero adverse environmental impact.
Wind energy is energy obtained from air moving at high velocity. This energy is harvested using windmills which convert mechanical energy to electrical energy.
Wind is inexpensive because it occurs naturally. However, a large expanse of land is required in order to mount sufficient number of windmills that will generate enough electrical energy for practical purposes.
This method of electricity generation is safe and does not lead to any environmental hazard unlike the burning of fossil fuels, use of nuclear energy or loss of habitat due to hydroelectric power generation.
