According to the chart above, what percentage of US energy is produced by all of the nonrenewable sources, combined?
Zanzabum

Answer:

91%

Explanation:

As per the given pie chart, Non-Renewable sources include Coal, Nuclear power, Natural gas, and Petroleum.

Percentage of Coal = 52%

Percentage of Nuclear power = 16%

Percentage of natural gas = 20%

Percentage of Petroleum = 3%

∵ Total percentage of non-renewable sources of energy = Coal + nuclear power + natural gas + petroleum

= 52%  + 16% + 20% + 3%  

=   91%

While the other 9% is renewable energy including 7% Hydropower and 2% of geothermal, wind, solar energy, etc.

Thus, 91 % is the combined percentage of US energy produced by all of the nonrenewable sources.
