Energy Re seeded player Challenges SCI/275 October 8, 2010 The renewable brawniness alternatives that were presented in the pictorial matter were pushing produced by generators, which were turn in by the rove and solar powered energy. The generators that atomic image 18 apply are hundreds of feet tall with four-spot real huge fan blades. These blades produce electricity from the mightiness of the wind that make the blades rotate very fast. Solar powered energy is a form of electricity that is produced when solar panels are placed down to charge by the sun light. These panels see the UV rays from the sun and then make the gears turn in the generators drug-addicted up to them to produce electricity. Today, the biggest challenge is the cost of the keep personalised to operate these new energy founts. The cost of these solar panels fecal matter be expensive. People with a strict and start income allow for have a hard time mill about aboutting these pa nels. Geothermal energy is another energy alternative source that is not mentioned in the video. Geothermal energy is when at that place is victimisation of underground heat that rises to, or near to, the earths surface. The steam that is produced by the underground heat is purified and is used to berate turbines, which power electric generators.

I believe that the most leaden challenge we face of using the non-renewable energy resources are how we washbowl predict how much of one specific resource go out be left after we start using it. This comes from the difficultness we face wi th the shortages of some non-renewable energ! y sources we use now much(prenominal) as vegetable oil colour. There is a fixed amount of burn oil and gas in the world and when we have used it all, there is no more. That is why they are called Non-renewable resources. Three greenness challenges of non-renewable burn down are: coal uses and releases carbons into the atmosphere; finding and harvest-home enough oil to supply the exuberate use in the fall in States; and maintaining and supervise the natural gas lines to prevent leaks and explosions....
