2. In response to the increasing cost of producing energy through traditional means, such as combustion, many utility companies have begun investing in renewable energy sources, chiefly wind and solar power, hoping someday to rely on them completely and thus lower energy costs. These sources require significant initial capital investment, but the operating costs are not so high; so the utility companies claim that they will provide stable energy supplies at low costs. As one can easily see, these sources will be less risky for the utilities than non-renewable sources, such as gas, oil, and coal, whose prices can fluctuate dramatically according to availability. The claim of the utility companies assumes which of the following?


  A. The public will embrace the development of wind and solar power.
  B. No new deposits of gas, oil, and coal will be discovered in the near future.
  C. The necessary technology for conversion to wind and solar power is not more expensive than the technology needed to create energy through combustion.

 

  D. Obtaining energy from non-renewable sources, such as gas, oil and coal, cannot be made less risky.
  E. Weather patterns are consistent and predictable.
