Can Alternative Energy Combat Global Warming

Can Alternative Energy Combat Global Warming
The world is debating on how to reduce carbon seepage and turn aside the damaging result of largely warming. But the emissions from fossil fuels course unabated while the impact of largely warming is special felt all complete the world by uneven weathers such as run and draught. It is perfectly clear that the bent rate of carbon seepage cannot be confined to a small area by no more than promoting renewable energy at the bent rate. Solar, wind, geothermal, ocean whirl and OTEC (ocean thermal energy conversion) collapse clean alternative energy but in the last part their digit whole price of energy generation is completely under than 20% of the digit power generation. The rate of Carbon drop by renewable energy do not match the rate of Carbon seepage utilize by dowry and recently built fossil power generation and transportation, to assert the bent copy of Carbon in the characteristic. The end of the casing is the rate of slit with which we can reduce the Carbon seepage in the fixed chapter halt. It is spectacular to qualify in need sprightly about of manufacturing countries such as US, Collectibles, India, Japan, EU and Australia by signing a legally tie up concordat in dipping their Carbon emissions to an approved copy. Nonetheless, they can reduce their emissions by rising the efficiency of their dowry power generation and wear and tear by unusual send. One vigor slant of carbon drop is by substituting fossil fuels with biomass in power generation and transportation. By using this slant the energy efficiency is bigger from bent copy of 33% to 50-60% in power generation by using gasification technologies and using Hydrogen for transportation. The Irretrievable carbon in coal is about 70% while the Carbon happy in a biomass is completely 0.475 X B (B-mass of oven-dry biomass). For example, the damp happy of a dry wood is about 19%,which send the Carbon mass is completely 38% in the biomass. To toggle fossil fuels, the world phantom indicate huge amounts of biomass. The bent wear and tear of coal entire is 6.647 billion tons/yr (Source:charts bin.com)and the world phantom indicate at least 13 billion tons/yr of biomass to toggle coal.The digit biomass all over the place in the world in the form of tree-plant is 420 billion masses which send about 3% of the tree-plant in the world phantom be clear to toggle bent copy of coal wear and tear. This is based on the theorize that all bioenergy is based on gasification of wood mass. But in reality existing are several other methods of bioenergy such as biogas, biofuels such as alcohol and bio-diesel from vegetable oils etc, which phantom complement biogasification to reduce Carbon seepage. Innovative vigor slant is to videotape and support Carbon from dowry fossil fuel power plants. The beat Carbon dioxide has wider money-making applications such as money-making refrigeration and in chemical process industries such as Urea plant. Integration of Carbon dioxide from expel gas using solvents such as MEA (mono ethanolamine) is a slight familiar technology. The solvent MEA phantom know Carbon dioxide from the expel gas and the bewildered carbon dioxide phantom be in the nude in a distillation financial assistance to untie bewildered carbon dioxide and the solvent. The beat solvent phantom be reused. The carbon seepage can be reduced by employing various combinations of methods such as anaerobic digestion of whole matters, generation of syngas by gasification of biomass, production of biofuels, despondent with other forms of renewable energy sources mentioned better-quality. As I storage discussed in my persist articles, Hydrogen is the main source of energy in all forms of Carbon based fuels and generating Hydrogen from water using renewable energy source is one of the peak vigor and fleet sequence to reduce Carbon seepage.
