Urgent needed

1. Geothermal energy uses the heat from the Earth as energy. It’s relatively cost-effective compared to other sources, particularly for electricity. However, GT energy production is limited to accessible locations. Is this a plausible future for GT? Why? How does geothermal energy compare to other renewable energy alternatives? 

2. Solar energy can be used for everything from powering small calculators by using photovoltaic cells to providing electricity to cities by using concentrated solar technology to drive turbines. Given solar power's potential, what do you think about constructing large solar farms--large areas of land with solar collectors for energy--in the Arizona and California deserts? Why? What potential dangers must be considered before acting?
