Good morning chairperson, timekeeper, opposing team and audience. The topic of today 's debate is South Africa should stop using coal to generate electricity and start using alternative energy sources.
We on the positive team agree with the definition given that South Africa should stop using coal to generate electricity because coal is a flammable black hard rock thats contains 65% carbon dioxide.This means that when burning this rock, it releases all the carbon dioxide into the environment.Using coal energy is bad because the impact of this fossil fuel on our health and our atmosphere is one dirty, expensive proposition. Coal emits more carbon per unit of energy than oil, and 80 percent more than natural gas. It accounts for 43 percent of global emissions.
But the question is, how did it come to south africa using coal to generate energy in the first?
Well,in South Africa we produce about 34 000 megawatts of electricity to meet current demand and this figure is growing year by year. The rising demand for energy from our growing population has led to the increasing amount of fossil fuels being used.The most economical method available to us is to use our abundant supplies of low-quality coal in Mpumalanga and the

Coal has traditionally dominated the energy supply sector in South Africa, from as early as 1880 when coal from the Vereeniging area was supplied to the Kimberley diamond fields. Presently, about 77% of our country 's primary energy needs are provided by coal. All of us want an affordable and reliable energy source which we can only get by using coal energy. Although using coal energy is significant for us and living without it would become impossible, we should always open our minds to the damage the continuous use of coal energy will eventually bring to us and to our
Throughout the centuries, humans have been attempting to find a way to power homes, cars, and other luxuries in the most efficient way possible. Coal and oil were two major sources that begin being exploited during the industrial revolution. Both have caused great controversy over the years from lawsuits to strikes. A new way to drill oil, hydraulic fracturing, was discovered and was an efficient means of drilling until its effects became prevalent. Also, when coal began to run out, a new method called mountaintop removal took hold, but continues to damage the earth.
Due to more and more cities switching from fossil fuels to cleaner, more sustainable sources of energy, coal became less and less a part of each Americans daily life. For example, in 1966, one of John Lindsays major campaign ideas that got him elected mayor of New York City planned to eliminate the use of coal in the city. He did this by “, requiring reduction of the maximum sulfur content of coal and oil from its original level of 2.8% to 1% in three stages in five years.” These sanctions made it impossible for coal to be used as a fuel source, leading New York to leave coal in the past and look for other methods of energy. However, just because coal vanished from parts of America, does not mean it disappeared entirely.
During this time, rises in the demand of coal-powered steam engines led to a rapid increase of coal mining (Wrigley 54). As the evolution of the market system took place, the small scale techniques that the industry had been using were not supplying a sufficient level of coal output needed to maintain the high demand in the manufacturing and transportation sectors. This deficiency prompted a transition for the coal mining industry that involved dangerous mining techniques and labor
How is coal formed? Hundreds of millions of years ago we had many trees, and other plant matter live near bodies of water and or swamps. After these trees and plants died over time were buried in the bottom of the lake or ocean, which built up many layers of dead plant material. Over millions of years drastic changes to the earths surface can cause the swamp to get flooded and buried.
The alternatives available at the moment are certainly unsatisfactory in many regards, nor are they well understood. So the issue is of high priority. Amy Jaffe also mentions that we are lowering the harm to the environment by ‘diversifying away from coal’. But ‘diversifying away’ implies alternatives, and she doesn’t provide any other than fracking. I intend to further research why countries like France banned fracking.
One of them is burning coal. The encyclopedia defines coal as a solid fossil fuel formed from the remains of land plants that were buried 300-400 years ago and exposed to intense heat and pressure over those millions of years. It is burned in power plants to generate electricity. Data says that 44% of the United States electricity comes from burning coal. The National Mining Association reported that in 2009, 55.4 percent of Maryland’s electricity came from it.
(8) Every country has a common cycle that they go through when developing their methods of energy creation; this cycle includes burning large amounts of fossil fuels without any care for the environment because they are cheap to use. Without any government regulation of the fossil fuel plants in these developing countries, it could spell trouble for the environment as these plants would be introducing large amounts of soot into the air which would damage the area around them as well as the citizens in those areas. But if you use nuclear you have almost no carbon emissions and much more power being produced than in a coal fired plant. But we must think of our own country before
Energy is a key factor in today's society, especially in Kentucky. Kentucky's main energy resource is coal, 91.8 percent of our energy comes from this resource but coal is nonrenewable, meaning that there is a limited amount of this type of fuel. Coal mining is also detrimental to the environment, people living and working in coal mining communities have a higher chance of getting lung cancer. with surface mining, this has been linked as a cause for poisoning local residences from the chemicals used in the mountaintop mining. there are still issues with the environment and natural wildlife in the surrounding areas of the coal mining as well.
There is a quote by President Barack Obama saying, “To truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy,” (“151 Inspiring Environmental Quotes”). He believes as many due that nonrenewable resources are harmful to all aspects of life. The energy we use now is harmful to our planet, to humans, and to animals. Scientists are taking steps to making the world a better place. They found sources that replenished naturally in a short amount of time and are less destructive in all aspects.
Soumya Saji Ms. Patiño English 2/16/18 Global warming as became a huge concern for today’s world. The rise of alternative fuel sources is to help this worldwide problem, as a result, electric cars have started to become a familiarity to everyday roads. Electric cars have many benefits and potentially does help with global warming, but it may not be as environmental-friendly as advertised.
Introduction In today’s world, most developing countries are in a race to build up the necessary infrastructure to scale up there operations and become the next global superpower. In this process, a lot of energy is consumed – be it for transportation, manufacturing or construction. This rapid growth of energy use seen over the past two decades have raised concerns for governments and energy-related organizations alike. Questions with regard to the supply, sustainability and exhaustion of energy sources abound, and while most developed countries have taken active steps to reduce consumption of scarce resources, the position of developing countries in this regard is still lacking.
Homero Castro Ms. Cabaj English IV, 3rd period 12 February 2018 Global Warming Global Warming is affecting the entire world. The issue of global warming is important because it’s affecting everyone.
Hydropower 4) Geothermal 5) Solar All electricity sources, renewable and nonrenewable, have advantages and deficiencies. Factors are includes: • Maintenance cost • Feasibility analysis. • Initial cost.
Global Warming Imagine a world where your house is as deserted just as the town you once lived in, also you have states that are touching water will probably be under water. A world were the air is so hot that it can hurt your throat just breathing. I am a Floridian and love the heat, but I hope that my generation does not have to go through global warming. Global warming is when “The earth’s surface becomes warm and as a result emits long-wave ‘infrared’ radiation”(Maslin
If its a cloudy day you can’t use solar power to heat up to make energy. As you can see its very inconsistent and unpredictable. It also takes more money to build these places non-fossil fuel plants rather than the traditional ones. What are some of the energy sources we use today The typical energy that a normal residents uses is electricity and natural gas.
