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).
Alternative energy is energy provided from sources other than the three fossil fuels: coal, oil, and natural gas. Alternative sources of energy include nuclear power, solar power, wind power, water power, and geothermal energy, among others.olar energy can be used to heat buildings and water and to produce electricity. However, the Sun does not always shine, and the process of collecting solar energy and storing it for use at night and on cloudy days is difficult and expensive. Solar energy systems can be either passive or active.
