Renewable energy 3_of_3
This document discusses various renewable energy resources including biomass, hydroelectric, wind, geothermal, and solar power. For each resource, it provides information on why the energy source is considered renewable and highlights some of the key advantages and disadvantages. The document concludes by noting that while renewable resources have certain benefits like being reliable and causing less pollution than fossil fuels, they also have disadvantages such as high upfront costs and intermittency of sources like solar and wind that require battery storage or backup generation.

- 25. Mrs. Buckingham hasstayed in this house twice. It is the coolest place, located in Moab, Utah. It relies on solar energy for all of the guests’ needs. (Hot water, lights, dishwasher, oven, laundry, hair dryers, entertainment, etc.) The solar panels collect energy from the sun all day and charged the batteries that were kept in a shed. There was a meter inside the house that showed how much energy was available in the batteries. At night, as she used electricity, the meters showed the battery life decreasing. That will teach you to conserve energy! During the week, a 3 day storm passed over Utah. The sun didn’t shine… but she still needed the electricity to cook dinner, turn on the lights and have hot water. The batteries quickly ran out and the power was off. Turn and Talk: What other alternatives could the house have to power the electrical needs? Thank goodness there was a back up generator! By using a tank of Natural Gas, we were able to generate (make) more electricity until the sun came back out. If we had used up all of this fossil fuel, we would have had to use candles!
