Question

in the united states, the flow of electrical power is vital to everyday existence. in fact, while there are many forms of power, when people say, the power is out, they usually mean just one thing: they do not have electricity. electricity is a secondary energy source, which means that it is created from the conversion of another source of energy. in most cases of fossil fuels, such as coal, petroleum, and natural gas, generate electricity. in 2020 about 1617 billion kilowatt - hours of electricity came from natural gas. it was the primary source for generating electrical power in the united states. most of the electricity in the united states is made from fossil fuels. nuclear power and renewable resources are also used to produce electricity. in the united states, people commonly use the word power to mean electricity. fossil fuels and renewable resources create electricity. turbines are large machines that turn energy into electricity. flowing water turns turbine blades to create electricity. electricity from solar sources is generated in different ways. solar - thermal generators and solar cells convert sunlight into electricity. which is the best summary of the passage? 1. most of the electricity in the united states is made from fossil fuels. nuclear power and renewable resources are also used to produce electricity. 2. in the united states, people commonly use the word power to mean electricity. fossil fuels and renewable resources create electricity. 3. turbines are large machines that turn energy into electricity. flowing water turns turbine blades to create electricity. 4. electricity from solar sources is generated in different ways. solar - thermal generators and solar cells convert sunlight into electricity. 5.

Explanation:

The passage discusses the importance of electrical power in the US, how electricity is a secondary energy source, the primary source for generating electricity (natural gas in 2020), and also mentions other sources like fossil - fuels, nuclear power, and renewable resources for electricity generation. It also briefly describes how turbines and solar cells work to create electricity. The best summary should cover all these main points.

Answer:

Most of the electricity in the United States is made from fossil fuels. Nuclear power and renewable resources are also used to produce electricity. In the United States, people commonly use the word 'power' to mean electricity. Fossil fuels and renewable resources create electricity. Turbines are large machines that turn energy into electricity. Flowing water turns turbine blades to create electricity. Electricity from solar sources is generated in different ways. Solar - thermal generators and solar cells convert sunlight into electricity.
