The tie molecules are embedded in the crystallites and transverse amorphous regions, acting as mechanical links between the crystalline domains, and play a decisive role in the resistance to fibril failure and overall mechanical properties when subjected to stress.
Sustainable Energy means energy sources that will allow the Earth to sustain balanced, healthy ecosystem s and human life. Fossil fuels â coal, oil and gas â are not sustainable energy sources because when we burn. them to create energy, they create massive levels of greenhouse gases, which result in human. impact on the global climate. That impact is creating an imbalance in the Earthâs climate that.
Renewable Energy Renewable energy is a greener way to produce electricity. The problem is that there is many forms of it available. Some are more reliable than others but they all have something in common. They all significantly reduce greenhouse gasses emissions. The main problem is that they are not constant for very long.
