why was electricity the most important power source for the second industrial revolution?
electrical power generation plants were pollution - free.
factories could be located near concentrations of workers and production costs were lower
some new industries, such as the iron industry, were dependent solely on electricity.
britain was rich in coal, so it did not have to rely on foreign supplies to power its factories.

Explanation:

Electricity allowed factories to be located near workers (reducing transportation costs for labor) and was more efficient/versatile than previous power sources (like steam which required being near fuel sources like coal for steam engines). Electrical power plants were not pollution - free (early ones used coal to generate electricity). The iron industry was not solely dependent on electricity (it had used other power sources like coal - fired blast furnaces before). Britain's coal situation is about coal, not about why electricity was important.

Answer:

Factories could be located near concentrations of workers and production costs were lower.
