Why Do We Use Renewable Energy?

"I challenge our nation to commit to producing 100% of our electricity from renewable energy and truly clean carbon-free sources within 10 years" says Al Gore, Nobel prize-winning climate change crusader, 2008. When utilize fossil fuel energy, a non-renewable resource, we are directly dumping 〖CO〗_2into the atmosphere. By the beginning of the industrial revolution, the fossil fuels rate in which it has burnt has increased from 3.4% in 2004, to 82.4 million barrels daily with the fastest rate of utilization within 16 years, according to Vital Signs 2005._5 1839 French scientist Edmund Bequerel was first to notice that when light was pointed to a battery cell, it would increase in electricity. 1883 British scientist Willoughby Smith discovered

One advantage for photovoltaic cells compared to other electricity sources is because it is renewable. Which means it is “energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat” as oxford dictionary states. Resources have two general categories, renewable and nonrenewable resources._7 Renewable are those that will not run out, such as solar power, which can be continuously transmitted to our planet and non-renewable resources, on the other hand, are resources that will run out at some point, these resources take millions of year to replace the quantity we are using in this period._9 Scientist are currently observing that photovoltaic cells capture and solar energy to produce electricity is clean, safe, plentiful and is one of the cleanest resource since it does not produce polluting gases, which would negatively affect the carbon dioxide rate in the environment._7 For the photovoltaic cells to function, solar energy is required to be converted into the electricity, The process of energy being generated in the sun is called nuclear fusion, where upon enormous amounts of energy are being created under enormous pressures and temperatures where upon hydrogen atoms join together and become helium releasing energy throughout the process. Einstein's law, E

The cost for the photovoltaic cells purchase and installation are at £720 in England and the efficiency of the solar cells have been proven flawed since not all energy available is being successfully absorbed. Costs make it impossible to harness the energy available all over the world since initial cost has become the first disadvantage. Scientists predict that as new technologies for collect energy are being discovered, costs for these solar panels are likely to decreases._1 The initial price for these solar panels in 1971 were at 100$ per watt, decreased to lower than 1$._4 In London a 4kWp sized system cost is £850, electrical bills are £135, and warranty for small damages are £155 and saves around 1,870 kg of carbon dioxide annually. Between 1980-2000 photovoltaic cells cost decreased 83 % but continue being one of the most expensive energy resources._6“Solar power is by far the most expensive energy resource. To produce 1 kilowatt the cost for utilizing solar power is $0.26, for nuclear power it is $0.02 and $0.03 for the equivalent quantity of gas power,” says Mark Robens from the “Disadvantage of Solar Power”, 2014. The average price for a complete photovoltaic system dropped 33% since 2011. Only one two- billionths part of the sun's energy reaches the earth, and the rest of it is lost and only 40% efficiency rate, thus 60% of the
