Replacing fossil fuels and using renewable resources can make a huge difference to the earth's environment. Renewable energies can be reused, so not only that, but they will never run out because there is the wind, the sun, the water that powers these energies. They make the Earth's atmosphere cleaner and fossil fuels are non-renewable and have limited quantities. Fossil fuels take millions to hundreds of millions of years to form. The demand for renewable resources is high as is the use of fossil fuels. Fossil fuels will soon become scarce and very expensive. As people around the world are consuming fossil fuels, renewable energy resources will replace fossil fuels in the future. There are many ways in which renewable energy can help build a secure future. One of these ways is solar energy, this type of energy uses the energy of the sun. RenewableRodriguez 2Technologies creates heating, light, hot water, electricity and cooling systems for buildings. This can replace fossil fuels. Fossil fuels are also used to produce electricity for homes and are found deep in the earth. Even though they are used to produce electricity, they have a devastating effect on the Earth's atmosphere and the environment because when used they release carbon dioxide, sulfur dioxide and other gases. This causes global warming; Global warming occurs when greenhouse gases such as carbon dioxide, methane, and other greenhouse gases are found in excessive quantities in the atmosphere and trap heat in the atmosphere. This not only causes the Earth's atmosphere to become warmer, but also causes the temperature of the Earth's surface to increase as well. This can increase the cancer rate percentage for the urban population… middle of paper… eothermal energy is heat from the earth this means you have to extract the heat that is in the earth. The energy produces no air pollutants and electricity is cheap. The demand for this energy is increasing. The importance of using renewable resources is important because it determines the future of the earth. Sooner or later the earth will overheat due to the use of fossil fuels and will become uninhabitable because the dense greenery there will turn into a desert if we don't stop. Rodriguez 4. The melting of ice caps causes sea levels to rise and the land to sink. If we can reduce greenhouse gas emissions we can prevent all this from happening. All these energies are renewable and clean. By using them now we can prevent global warming. By using clean energy we build a cleaner earth and a healthier environment one step at a time.
