The renewable energy alternatives that were presented in the tv set were energy produced by generators, which were supply by the wind and solar powered energy. The generators that be use are hundreds of feet tall with tetrad very huge fan blades. These blades produce electricity from the imbibe 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 catch the UV rays from the sun and then make the gears turn in the generators hooked up to them to produce electricity.
Today, the biggest challenge is the cost of the living personal to operate these new energy sources. The cost of these solar panels tail assembly be expensive. People with a strict and write down income will have a hard time acquiring these panels.
Geothermal energy is another energy alternative source that is not mentioned in the video. Geothermal energy is when there is growing 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 become turbines, which power electric generators.




I believe that the most alpha challenge we face of using the non-renewable energy resources are how we can predict how much of one specific resource will be left after we start using it. This comes from the paradox we face with the shortages of some non-renewable energy sources we use now such as oil. There is a fixed amount of blacken 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 special K challenges of non-renewable fuel are: coal uses and releases carbons into the atmosphere; finding and harvest-tide enough oil to supply the exuberate use in the join States; and maintaining and monitoring the natural gas lines to prevent leaks and explosions....If you want to withdraw a full essay, order it on our website: Orderessay
