Concern for environment has increased and spread over recent years. Pollution-a major environmental concern. Types and sources and effects of pollution.
This essay discusses some of the major advantages and disadvantages of nuclear energy. Nuclear power is generated using Uranium, a mineral of which one of the isotopes, U- is unstable.
The nucleus breaks down resulting in the emission of heat and radiation followed by a chain reaction. This is called nuclear fission and this process liberates a large amount of energy, but the process also releases radiation which is very dangerous.
What are the Advantages of Nuclear Energy? Clean Energy Nuclear energy has the ability to produce electricity without greenhouse gas emissions.
It produces electricity without pollution. It is cleaner than many other forms of energy production. High Quantities Nuclear reaction releases a million times more energy, as compared to hydro or wind energy. Large quantity of energy is generated from a single nuclear power plant.
High Reserves Nuclear reactors make use of uranium as fuel and produces huge amounts of energy from small amounts of uranium. The Earth has the high reserves of uranium. Current estimates put the uranium supply as enough to last for 30 to 60 years.
Moreover other fuel cycles like Thorium are available for power generation. Whereas, oil reserves and other fossil type fuels are likely to run out shortly. Reliability Nuclear power plants operate reliably and have a continuous output of power.
The plants do not generally face operations and maintenance problems. This is a contrast to other alternative energies which depend on the activity of the weather. Low Operating cost Although nuclear power reactors are expensive to build, they are relatively cheap to operate.
Fuel is inexpensive and a plant can be operated by small number of people, approximately 10 people. Concentration The nuclear energy is by far the most concentrated form of energy, so it can be produced in large quantities over short periods of time.
Low Waste Produces small amounts of waste and waste is more compact. Cheap Nuclear energy produces electricity at a competitive price and is generally comparable in output to coal plants. Location A nuclear plant is not dependant on local sources like oil and coal and can be set up in any part of the globe.
It also does not require a lot of space and so can be placed in already developed areas and the power does not have to be transferred over long distances.
What are the Disadvantages of Nuclear Energy? Nuclear Weapons Threat It has potential nuclear proliferation issues. Some reactors produce plutonium which can be used to make nuclear weapons. Nuclear weapons are a major threat to the world as they can cause a large-scale devastation.
High Capital Intensive Nuclear Plants require a high level of technology and a major initial capital investment.This started with a tweet.
I’m embarrassed how often that happens. Frustrated by a sense of global mispriorities, I blurted out some snarky and mildly regrettable tweets on the lack of attention to climate change in the tech industry (Twitter being a sublime medium for the snarky and regrettable). Climate change is the problem of our time, it’s everyone’s .
In this essay, I want to go into a bit more detail about how a strategy of pushing back on Iran should address the Iranian nuclear threat and the Joint Comprehensive Plan of Action (JCPOA. by Judith Curry Right about now would be a good time for people who care about climate change to acknowledge our clean energy crisis.
