Essay / Using green energy to fight global warming - 617
Green energy is a type of energy that we use daily. We have many types of energy, including coal, oil, wind, electricity, wind, solar geothermal, water, natural gas, biomass, nuclear and hydrogen. Of these 12 energies, only wind, solar, geothermal, water and biomass are renewable and green. While 4 of the remaining energies, coal, oil, natural gas and nuclear are not renewable and are not green. Finally, the 2 remaining energies, electricity and hydrogen, are secondary energy sources. (English online)Based on the graph below, we can reduce the life cycle of greenhouse gases and stop the pollution that causes global warming (Union of Concerend Scientists).Graph: (IPCC)By the way From coal and fossil fuels to green energy, we will save energy and our coal and fossil fuels will replenish themselves. Once it recovers and our population is too large to be supported by renewable energy alone, we will be able to use our newly formed coal and fossil fuels. To further support our refined lifestyle. In the meantime, we need to build facilities using renewable energy. Despite the high cost of construction, once the facility is built it will operate at low cost and, with most of our current technologies, the fuel will be free. Here's how nature affects whether or not green energy is better than coal and fossil fuels. In 2012, Hurricane Sandy damaged fossil fuel-dominated power generation and distribution systems in New York and New Jersey, leaving millions without power. In contrast, renewable energy projects in the Northeast weathered Hurricane Sandy with minimal damage or disruption (Union of Concerend Scientists). So if we switch to green energy now, the rest of the states won't be as badly damaged. (Union of Concerend Scientists)Currently we can gain about 482.2...... middle of paper... ...Gas combined cycle 70 50 10 1.68 0.88 0.51 45.60 13 .71 5.50 8.09 2.86 1.29 93 84.6 40Natural gas combustion turbine 110 70 60 8.09 5.74 3.20 14.52 10.53 5. 26 29.90 3, 57 2.67 92 80 10 Pulverized coal, washed 120 50 10 8.40 1.92 0.56 33.60 27.50 13.08 5.90 3.70 1.62 93 84.6 80 Charcoal, pulverized, unwashed 40 40 40 5.01 4.45 3.94 84.6Coal, combined cycle with integrated gasification 180 80 60 11.00 3.17 2.22 130.03 3 8.67 25.00 11.12 7.25 1 .15 80.96 80.96 75Nuclear 120 60 40 8.20 3.10 2.28 127 85.66 12.80 6.00 .49 .42 90.24 90 8 Basically, if we change now, we can save the America from collapse, save more money and produce lots of electricity that will allow us to go further in technology.
