The reason alternative energy resources are not widely used.
Answer to Problem 43R
The alternative sources of energy are not more widely used due to the high cost of the devices and the high maintenance cost.
Explanation of Solution
Introduction:
The alternative energy sources are solar energy, wind energy, geothermal energy and tidal energy. These energy sources are non-polluting.
The solar energy converts into electrical energy by the solar cells. The solar cells are made of semiconductors. The cost of the manufacturing of solar cells is very high. Similarly, the turbines and other devices for wind energy are expensive and maintenance is also expansive.
Conclusion:
Therefore, alternative sources of energy are not more widely used due to the high cost of the devices and the high maintenance cost.
