Today, many countries mainly developed nations are dependent on non-renewable energy sources such as fossil fuels (oil and coal) and nuclear power. People call these sources, non-renewable energy because they cannot be regenerated or replaced once it is used. These sources are sources that exist in a limited amount on earth. University of California College (2009) state that over 85% of the energy used in the world is from non-renewable supplies. Most of countries in this world need these sources of energy for industrialization. Many countries use non-renewable energy sources because they are very concentrated forms of energy. Nevertheless, non-renewable energy is bad for environment because it causes of pollution and can lead to global warming. We need renewable energy sources to help us continuing our lives and replace the non-renewable energy sources. Renewable energy is energy, which comes from natural resources, such as sunlight, rain, wind, and geothermal heat, which are renewable.
Renewable energy is an environmental concern because it affects environment. It affect the environment by give some benefits to it. The benefits are it keeps the environment clean because the renewable sources produce little or no pollutions. A country with little pollutions will be more attractive to visit and if many people come to visit the country it will be good for its economy sector too. Renewable energy also prevents extinction of natural resources for our future generations. This renewable energy is affect human because it can create job opportunity for people and make people save more money because some of renewable energy such as sunlight and rain can used without people pay for it. It also affect human because people in a country with high use of renewable energy will be healthier because the country will only produce few pollutions. Less pollution will also lead a country to gain more prosperity for its nation. Some example of
