Which sentence best supports the inference that renewable energy may not be the sole solution to solving the current energy crisis?
Renewable Energy
Turning on your computer or charging your cell phone requires electricity. To produce electricity people must harness power from
an energy source. Coal burning power plants and nuclear fission reactors are two popular methods for producing electricity. Although
these energy sources can produce ample electricity for consumption, coal power plants and nuclear fission reactors have notable
problems, however. As with all fossil fuels, burning coal creates air pollution and greenhouse gases that add to the planet's global
warming problem. Even though nuclear fission reactors only produce steam and no air pollution, these power plants do create
physical nuclear waste that is difficult to dispose of. So, how do people solve their energy needs without polluting the planet?
One of the most promising forms of energy production comes from renewable energy sources. Renewable energy refers to the
harnessing of energy from systems that naturally replenish over time. Solar power and wind power are two well-known examples of
renewable energy, but renewable energy comes in many forms. For example, geothermal energy harnesses the energy produced
from geysers and geothermal vents, tidal energy harnesses the power produced by ocean tides.
Nevertheless, renewable energy sources do have their limits. Unlike certain nhurenewable energy sources, such as fossil fuels or
nuclear, location is extremely important for renewable energy sources. For instance, solar power can't produce much electricity in
regions that experience heavy cloud cover, and wind power cannot produce electricity in areas without wind. Also, powering even a
small town often requires many wind turbines or solar panels. These points are important to weigh as people seek to address future
energy concerns
Renewable energy sources are promising because these systems produce electricity without creating much pollution As
thumanity's need for electricity continues to grow, renewable energy could play a crucial role in the future.
