The U.S. Department of Energy has set a goal of reaching less than $1 a watt—not just for the solar panels, but for complete, installed systems—by 2020. Green thinks the solar industry will hit that target even sooner than that. If so, that would bring the direct cost of solar power to six cents per kilowatt-hour, which is cheaper than the average cost expected for power from new natural gas power plants. All parts of the silicon solar panel industry have been looking for ways to cut costs and improve the power output of solar panels, and that’s led to steady cost reductions.

Which choice best describes data from the graph that support the conclusion?

a) Natural gas is the most cost-effective because it is abundant and can be reproduced, but researchers are finding ways to use other forms of energy to offset costs.

b) The U.S. Department of Energy wants to cut costs of all forms of energy production to make it more affordable, with a goal of 2020.

c) Solar energy has its setbacks, like being expensive to reproduce, but researchers are finding ways to increase applicability, like decreasing costs.

d)There are variations of solar energy that require extensive installation systems, so researchers are streamlining the approach for installation and increasing output.

The average levelized cost for plants entering service in 2017 is highest for solar (thermal) energy and lowest for natural gases; it seems to show that the more renewable a resource, the higher the levelized cost. -Minan, Tenpa, Loren

The correct answer choice is c because it is the only choice that related the information in the graph to the last sentence in the paragraph. Choice a talks about natural gas, choice b does not mention solar energy at all, and choice d is to specific and the information in the choice is not mentioned in the paragraph or the graph. Loren, Tenpa, Minan

C) because as shown by the graph, solar energy is considered the most expensive compared to the rest. -Jerry, Raza, Nghi, Nathan

The correct answer is C as researchers are working towards making solar energy more affordable by finding new ways to decrease the price.

The U.S DOE plans to have energy cost less than 1$ an hour by 2020 but steady advancements in solar energy seem to be quicker and even cheaper - Tenpa, Amelia, Minan and Loren

The U.S. Department of Energy wants solar power to cost less than $1 per watt by 2020. Green thinks it could happen even sooner, making solar power cheaper than new natural gas plants.
