Solar energy is renewable. what could be an economic factor that prevents the maximum exploitation of this resource?

An economic factor could be the cost associated with generating energy from sunlight. The main cost factor is related to the power-generating equipment, such as solar panels or solar heat exchangers, as these technologies are still relatively new and have not reached a stage of economical mass production. Transmission of energy to households is not a major cost and power grids already exist within most regions.  

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
