Question

what percentage of electricity was generated from nonrenewables?
list some positive reasons to switch to renewables.
list some drawbacks of switching to renewables.

Explanation:

Step1: Identify non - renewable sources

Non - renewable sources in the pie chart are Coal (35%), Natural gas (23%), Nuclear (10%).

Step2: Calculate the sum

Sum the percentages: \(35\%+23\% + 10\%=68\%\)

Positive reasons to switch to renewables:

• Environmental benefits: Renewables (e.g., wind, solar) produce less greenhouse gas emissions compared to non - renewables (coal, gas), helping combat climate change.
• Energy security: Reduces dependence on imported fossil fuels (non - renewables), as local renewable resources can be harnessed.
• Job creation: Growth of renewable energy industries (e.g., solar panel installation, wind turbine manufacturing) creates new jobs.

Drawbacks of switching to renewables:

• Intermittency: Sources like solar (only during daylight) and wind (depends on wind speed) are intermittent. Energy storage solutions (expensive) are needed to bridge supply gaps.
• High initial costs: Building renewable energy infrastructure (e.g., solar farms, wind parks) has high upfront costs compared to some existing non - renewable power plants (though costs are decreasing).
• Land use: Some renewable projects (e.g., large - scale solar farms) require significant land, which can impact local ecosystems and land use for other purposes (e.g., agriculture).

Answer:

68%
