Renewable and Non Renewable Energy

Electric power is the force of energy, is the thing that machine and electrical objects need to do something. Some types of energy are renewable energy and non-renewable energy. A renewable energy is a substance of economic value that can be replaced or replenished in the same amount or less time as it takes to draw the supply down. And is something thatcan be replaced faster and is derived from natural processes that are replenished constantly. The 16% of global use energy consumption comes from renewable. Some renewable energy has essentially anendless supply. Some types of that energy are: wind energy, geothermal energy, hydrogen energy, bio energy, solar energy and ocean energy. A non-renewable energy is something that is not being replaced aswe consume it. For example: fossil like coal, oil and gas or mineral like copper.  Most precious metals are considered renewable as well; even though they are not natural replaced; they can berecycling because they are not destroyed during their extraction and use. So, which type of energy is better to use?

Scientists have advanced a plan to power 100% of the world's energywith wind, hydroelectric, and solar power by the year 2030. According to a 2011 projection by the International Energy Agency, solar power generators may produce most of the world’s electricity within 50 years,dramatically reducing the emissions of greenhouse gases that harm the environment. The most important renewable energy that can help our World are:
* Wind energy: Generates electricity by using the wind.They common use to commercial use; the power output of a turbine is a function of the cube of the wind speed, so as wind speed increases power.. This could require wind turbines to be installed overlarge areas, particularly in areas of higher wind resources. Offshore resources experience mean wind speeds of ~90% greater than that of land, so offshore resources could contribute substantially...
