Determine whether the study described in the research summary for Guided Practice Exercise 2 is a randomized comparative experiment. If it is, describe the treatment, the treatment group, and the control group. If it is not, explain why not and discuss whether the conclusions drawn from the study are valid.
Solar Energy and Its Uses. Utility scale solar energy facilities generate electricity that is sent to energy consumers via electric transmission systems. On a smaller scale, solar energy facilities can be used to generate electricity or hot water for use in individual buildings.olar energy facilities use concentrating solar power (CSP) as the heat source to boil water, or they convert sunlight directly into electricity using solar cells, also known as photovoltaics (PV).
Solar energy. Solar energy is the energy that is in sunlight. It has been used for thousands of years in many different ways by people all over the world. As well as its traditional human uses in heating, cooking, and drying, it is used today to make electricity where other power supplies are absent, such as in remote places and in space. It is becoming cheaper to make electricity from solar energy and in many situations it is now competitive with energy from coal or oil. A solar cooker can be used for cookin
