In a world without coal power, we must use alternative sources of energy to power our lives. Renewable energy sources, such as wind and solar, will soon fill this void.
Renewable energy is popular with the public, as it has few negative health and environmental impacts. Soon, we will be able to store energy from these sources, which is particularly useful on days which aren’t sunny or windy. Elon Musk recently announced he will build the world’s largest renewable energy battery in South Australia. This has made battery storage a reality for many states and countries. However, it will take time for this technology to become cost-effective, commonplace, and efficient.
Until then, if we stop using fossil fuels, our energy demand will exceed our

Health Impact
When people think of nuclear power, they often think of Chernobyl and Fukushima. They think of accidents and the huge environmental and health impacts. Yet these accidents are simply that – accidents.
Every energy source has risks. The risks of nuclear power have been more widely publicised than those of other energy sources, and more widely publicised than the potential benefits of nuclear power. Despite the Chernobyl and Fukushima accidents, nuclear power has prevented 1.8 million deaths worldwide. This is for two reasons.
Firstly, using nuclear power reduces our need for fossil fuels, which leads to fewer CO2 emissions, thereby reducing the number of deaths attributable to climate change.
Secondly, coal mining is an extremely dangerous occupation. Nuclear power, historically, has had far fewer deaths per unit of energy produced compared to coal. Even solar power constitutes a greater risk of death per unit of energy, simply because people fall during installation on roofs.
If nuclear power is phased out prematurely, NASA estimates (despite the risks) there would be an additional 7 million deaths

But fossil fuels can be equally contaminating. For example, think of the catastrophic effects on the environment following an oil spill. But just like with preventing oil spills, there are safety measures in place to minimise the risk of a nuclear meltdown.
Modern reactors are far safer than the Fukushima and Chernobyl plants. In fact, the Fukushima and Chernobyl reactors would never meet current Nuclear Regulatory Commission Standards. With improvements in technology, nuclear power is becoming safer. For example, MIT reviewed thorium reactors, and concluded using thorium rather than uranium will greatly improve safety:
• Thorium plants can be operated at normal atmospheric pressure, unlike uranium plants. By working at normal atmospheric pressure, thorium plants will have a much smaller risk of explosions than uranium plants;
• There is an inbuilt safety feature of thorium plants – if the reactor overheats, it automatically (without human intervention) turns off and begins to cool. This eliminates the risk of nuclear meltdowns, and protects workers from being exposed to dangerous
Nuclear power is a growing source of energy to most of the world for many benefits. People doubt the significant of nuclear power because of one accident. Due to this accident, the world has only seen the flaws in nuclear power and not the many benefits it has to offer. Nuclear power would benefit worldwide if people would let go of the past and look towards the future. Nuclear power is a better alternative energy because of its economic and environmental benefits.
Specific purpose: To persuade the audience that nuclear power is the best source of energy today.
Instilling this new way of energy usage into off-grid communities will inevitably increase the state of living for those in cities and other well-populated areas. The change to renewable energy sources could drastically lower the pollutants currently being dispersed into the atmosphere by coal mines and other harmful power options, increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions. a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants (“Benefits of Renewable Energy Use”). Electricity production accounts for more than one-third of U.S. global warming emissions, with the majority generated by coal-fired power plants.
Central Idea: Nuclear energy only contributes a small amount to the world’s electricity yet it has hazards and dangers that far out-way its benefits. There are many other alternative power producing sources that can produce energy more efficiently and more safely than nuclear power plants can.
...nce World War II to the present day, the technology of nuclear power has increased significantly in terms of energy output and safety. The energy efficiency of nuclear power is far superior to its counterpart fossil fuel and renewable energy. Compared to fossil fuels, tiny amounts of fuel used by nuclear reactors is equivalent to a large sum of coal. This is a no brainer. Why mine a ton of coal when a little uranium can be used to gain the same amount of energy? Not only is it efficient, it’s safe to use. Used fuel is packed away in storage safely, so there isn’t any chance of radiation leaking out. In the present day, nuclear power incidents haven’t been occurring lately. Advancements in technology and equipment used have made nuclear energy a very reliable and safe source of energy. With today’s energy needs, nuclear power has the ability to keep up in the race.
“Face it. Nukes are the most climate-friendly industrial-scale form of energy” (Power, Reiss, Pearlstein, 655). This statement is what I’m trying to promote through my argument. It also ties Inconvenient Truths: 10 Green Heresies by Matt Powers, Spencer Reiss, and Jonanna Pearlstein and Nuclear Power is Best Energy Source: Potchef Stroom together by bring out the main point all authors are trying to get across. Global warming has been a big concern for years now and one of the biggest causes for it, is the burning of fossil fuels to get energy. People that live in the United States of America use a huge amount of energy in their daily lives and that amount continues to grow with our population growing with it. My purpose of this piece is to persuade people to switch to nuclear power for a cleaner energy source because it’s the cleanest energy source.
Nuclear energy has been a controversial source of alternative energy since it has been made practical in the 1950s. The goal of nuclear energy was to find a sustainable resource that would be able to replace the use of fossil fuels. Due to the exploitation and finite supply of resources such as oil and coal, an alternative to fossil fuels was needed quickly in order to provide sustainability for the future of the world. A question arises, however, when nuclear energy is considered as a source of energy: Is nuclear energy a reasonable alternative to fossil fuels?
Media coverage of such cases have made the public less comfortable with the idea of moving further towards nuclear power and they only opt for reducing human activities to reduce global warming. It is true that there have been some notable disasters involving nuclear power, but compared to other power systems, nuclear power has an impressive track record. First, it is less harmful and second, it will be able to cater for the growing world population. Nuclear power produces clean energy and it delivers it at a cost that is competitive in the energy market (Patterson). According to the US Energy Information Administration, there are currently 65 such plants in the Unite States (National Research Council). They produce 19 percent of the total US energy generation.
Note that nuclear energy is another alternate fuel source, which would be like a really expensive Prius that sometimes leaks radiation when it suffers a major breakdown. Which is a scary thought because many Prius owners don’t even know how to change a flat tire.
In her book Coal A Human History, Barbara Freese states "The mundane mineral that built our global economyand even today powers our electrical plantshas also caused death, disease, and environmental destruction" (front flap) Today, coal provides for more than 55% of the electricity generated in the U.S. (Cullen, Robert Vol.272) Coal miners have had one of the most dangerous jobs in history before government regulation. Many miners had to work underground for 10 + hours a day and 6 days a week(Cobb, James "Coal") The number of deaths per year is the equivalent of a Titanic going down in the nation's coal fields each year (Turkington, Carol) According to James Cobb from the World Book Online Reference Center mine safety involves four main types of problems including accidents involving machinery, roof and rib failures, accumulations of gases and concentrations of coal dust.
The costs will be minimized once we fully develop them and put them into full use. Works Cited Class Notes http://www.eia.doe.gov/kids/classactivities/energyarticles.html http://www.solar4power.com/ http://www.environment.sa.gov.au/reporting/human/energy/renewable.html.
The energy industry is beginning to change. In today’s modern world, governments across the globe are shifting their focuses from traditional sources of power, like the burning coal and oil, to the more complex and scientific nuclear power supply. This relatively new system uses powerful fuel sources and produces little to no emissions while outputting enough energy to fulfill the world’s power needs (Community Science, n.d.). But while nuclear power seems to be a perfect energy source, no power production system is without faults, and nuclear reactors are no exception, with their flaws manifesting in the form of safety. Nuclear reactors employ complex systems involving pressure and heat. If any of these systems dysfunctions, the reactor can leak or even explode releasing tons of highly radioactive elements into the environment. Anyone who works at or near a nuclear reactor is constantly in danger of being exposed to a nuclear incident similar to the ones that occurred at the Chernobyl and Fukushima Daiichi plants. These major accidents along with the unresolved problems with the design and function of nuclear reactors, as well as the economic and health issues that nuclear reactors present serve to show that nuclear energy sources are not worth the service that they provide and are too dangerous to routinely use.
Thesis Statement: The world must continue to develop wind energy even though it cannot supply all electricity we need, because it is renewable, non-polluting, and convenient for people can use wind energy to produce their own supply. Wind is a form of solar energy. (“Wind Energy” n.d.) Wind are produced by the uneven flowing of heat, and the rotation of Earth.
The greatest disadvantages of nuclear energy are the risks posed to mankind and the environment by radioactive materials. ‘On average a nuclear plant annually generates 20 metric tons of used nuclear fuel cla...
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
