Ventajas y desventajas de la energía eléctrica??

Answer 1

Answer:

Advantages and Disadvantages of Electric Power

Advantages:

Electric power has many advantages domestically and industrially, as most of the equipment run by electric power. Brightness in the night is only possible by the use of electricity. Almost all the factories and industries are running due to electric power. The advantage of electric power is its reliable and uninterrupted supply runs the equipment efficiently and continuously. The transportation of electricity is easy once the transmission lines are functional. They work for years and need no or very less maintenance. The invention of electric power is one of the best inventions which have changed human life drastically. It allows people to do more leisure activities.

Disadvantages:

In the conventional system to generate electric power, coal is burnt to generate heat which boils the water to produce steam. The steam produced is used to run the turbines which in turn generate the electricity. This is a very old method to generate electricity which produces too much air pollution as a by-product. Due to the burning of coal, carbon monoxide, carbon dioxide, different oxides of sulphur and nitrogen are pumped into the atmosphere which pollutes it badly. As carbon dioxide is the greenhouse gas and its excessive presence in the atmosphere raises the earth’s temperature.

Distribution of electric power is in two types of current, AC and DC. Alternating current is 3 to 4 times more dangerous as compared to direct current. It causes more muscle contraction as it reduces skin resistance by stimulating sweating

Answer 2

Answer:

Explanation:

Electricity can be used to heat either storage or continuous flow water heaters, and can also be used as a booster to solar or heat pump water heating systems.

The advantage of electricity is its reliable supply. However, in terms of sustainability and energy efficiency, conventional electric hot water heating is not a preferred option except as a booster system.

Conventional electric systems are less energy efficient than solar and heat pump systems, and generating electricity from fossil fuels produces greenhouse gas emissions. As well as these environmental costs, rising electricity prices also provide an incentive to seek more efficient energy sources.
