Question

so just how do we get electricity from water? actually hydroelectric and coal - fired power plants produce electricity in a similar way. in both cases a power source is used to turn a propeller - like piece called a turbine, which then turns a metal shaft in an electric generator. a coal - fired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. the results are the same. based on the information above, which statement is true about water and coal? 1. both can be used at the same electric power plants. 2. both are able to generate the same amount of electricity. 3. both can produce the power needed to generate electricity. 4. both are the main power sources used at electric power plants.

Explanation:

The text explains that both water in hydro - electric plants and coal in coal - fired power plants are used to turn a turbine which then generates electricity in a similar way. This shows they can generate the same amount of electricity.

Answer:

1. Both are able to generate the same amount of electricity.
