Nuclear Power Nuclear power plants can be good and bad. The new power plants have nine inch thick walls that can withstand pressure of 2,250 pounds per square inch. “It serves as an important barrier for any radioactive material produced in the reactor core during the operation of the plant.” Nuclear power plants are good because it generates heat, and electricity. Although power plants are good, they can also be bad.
Commonly, Nuclear Power plant generates electricity with minimum emissions that are detrimental to the environment. It works on the concept of Nuclear fission -Splitting of a single Uranium-235 atom by the incident of a neutron leads to the release of ~200 MeV of energy, a significant 200 million times more than an energy released from a chemical reaction. Pressurized water reactor (PWR) is the widely installed class in the fleet of nuclear power plants across the world. PWR uses 4~5 % of enriched U-235 as fuel and water as moderator and coolant. The energy released from the fission boils the water and generates high enthalpy steam.
Nuclear power plants are all over the U.S., with 99 nuclear reactors in 30 of the U.S. states, but what are nuclear power plants? Nuclear power stations are thermal, which means they get the energy from heat. These power stations heat up and make steam, which turn turbines and conduct electricity. The Palo Verde located in Tonopah Arizona is the largest power plant in the U.S. with three nuclear reactors and averagely gives off 3.3 gigawatts. As fuel, nuclear power plants use uranium which releases high amounts of carbon dioxide into the atmosphere when mined.
There are different types of reactors such as the Light-Water Reactor, Pressurized Heavy Water Reactors, Gas-cooled Reactors and many more. Nuclear power is generally designed as a base-load plant[2], they operate with high capacity factors. This electricity generation technology is not available to every country because not everyone can afford the nuclear plant and that is one of the disadvantages of the nuclear power plant. It can also be dangerous in the environment if used incorrectly, therefore, it is built far from where people live. Coal-Fired Power Coal-fired power plant converts the chemical energy that is embedded in coal into heat.
Wave Energy Wave energy is a great alternative energy to fossil fuels. When people think of waves, they usually think of surfing, the beach, waves crashing down on the shore, but most people don’t think of energy being converted through waves. This energy is very unique, and more people should know about it, and should definitely be used more. Ocean wave energy is a good alternative to fossil fuels, because is renewable, a powerful clean source, and there are multiple options of ways to harness it. How It Works
In a nuclear power plant, the water in the reactor serves as a coolant for radioactive material. That way it will prevent it from overheating and melting. It produces electricity by boiling water into stream. It also uses uranium fuel. The process called fission for nuclear energy splits atoms of uranium in the reactor.
Nuclear power plants are bad for the environment and for the organisms in and around it because they are so deadly and destructive. In power plants the nuclear reaction of fission is forced, creating an extreme amount of energy and deadly radiation. Nuclear fission is the splitting of a heavy nucleus into two lighter ones, for fission to occur requires extreme heat and pressure. When the nuclear fission occurs it produces electromagnetic radiation in the form of gamma rays, which is the most deadly form of radiation (britannica). Everything within a 50 mile radius will receive an average dose 0.01 millirem per year (nrc.org).
Energy produced by fossil fuel is largely responsible for carbon emissions, Nox’s and Sox’s leading to global warming. Concerted actions are required on the planet regarding to reduction in consumption of fossil fuels and to mitigate the carbon emission. Ocean energy can be produced from blowing wind, current of ocean, tidal waves, thermal, gradients in salinity as well as from the sources of ocean plankton. Ocean energy which has a large potential faces, some interdisciplinary; complications which are to be overcome like automation, cost reduction, speculation, instructress, environmental impacts and so forth. In future, areas that can explore the Marine Renewable Energy seascape through viable plan include proceed material, automation, informatics
The invention that has affected our lives the most is nuclear power plants. It may provide us energy, but have you noticed how dangerous, very expensive, and dirty it is? One reason nuclear plants are dangerous is because it can or will release enormous amounts of radiation into communities. If radiation is released many people will have to evacuate. Many of them may never come back.
Sometimes being an environmental activist is not the easiest job in the world, but it is mostly fun if you make it that way. Each day differs. One day you might have people standing with you and shouting chants on the streets, or people bashing you and telling you, “you’re crazy”. As I have traveled across the world, I have had the pleasurable experience of meeting new friends and informing people of the cons of having a nuclear power plant in our world. I also have attended many protests, assemblies, and meetings, and have spoken at them.
wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources
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.
Geothermal is available everywhere in various forms. Geothermal power production, as discussed previously, provides reliable baseload power to the electricity grid and geothermal heat pumps are heating and cooling homes and businesses in all 50 U.S. states, and around the
The energy from waves can be taken directly into electricity-producing machinery and used to power generators and power plants nearby making “clean energy”. Which are hard to find these days. Another benefit to using this energy is its nearness to places that can use it. Lots of big cities and harbors are next to the ocean and can harness the power of the waves for their use. About 40 percent of the world’s energy is produced by the “waves”.
Hydropower 4) Geothermal 5) Solar All electricity sources, renewable and nonrenewable, have advantages and deficiencies. Factors are includes: • Maintenance cost • Feasibility analysis. • Initial cost.
