Q6 Discuss the advantages and disadvantages of fuel cells over conventional power plants in producing electricity?
Fuel cells offer several advantages over conventional power plants, including higher efficiency and lower emissions, as they generate electricity through electrochemical reactions rather than combustion. They can operate quietly and have a smaller footprint, making them suitable for urban environments. However, disadvantages include higher initial costs, limited infrastructure for hydrogen production and distribution, and challenges related to fuel storage and transportation. Additionally, the technology is not yet as widely adopted or proven for large-scale electricity generation compared to conventional power plants.

What are the advantages and disadvantages of fuel cells over conventional power plants in producing electricity?
Fuel cells offer several advantages over conventional power plants, including higher efficiency and lower emissions, as they convert chemical energy directly into electricity without combustion. They can also operate quietly and have a smaller physical footprint. However, disadvantages include higher costs for fuel cell technology and infrastructure, as well as challenges related to fuel supply and storage, especially for hydrogen. Additionally, fuel cell systems may have lower scalability compared to traditional power plants.
What are the advantages of burning coal for electricity?
The only advantage of producing electricity from coal is that it will cost cheaper.
What are the advantages and disadvantages of producing electricity by photoelectric cells?
Advantages: Photoelectric cells produce electricity without emissions, reducing environmental impact. They are also scalable and can be used in remote locations. Disadvantages: They can be expensive to install initially and are dependent on sunlight, making them less reliable in areas with inconsistent sunlight. Additionally, the manufacturing process for photoelectric cells can have environmental impacts.
Advantages and disadvantages of selective breeding in English Bulldogs?
The advantages of selective breeding include producing a dog that meets the standard of the breed. Disadvantages include producing dogs with very short faces, squat legs, and large bodies.
What are the advantages and disadvantages of producing sexually?
An advantage is their offspring may be more adaptable to changes in the environment.
What are the methods of producing electricity?
Some common methods of producing electricity include burning fossil fuels (coal, natural gas), harnessing renewable energy sources (solar, wind, hydroelectric), nuclear power generation, and using geothermal energy. Each method has its own advantages and disadvantages in terms of cost, environmental impact, and reliability.
What are the methods of producing electricity from different sources?
Some common methods of producing electricity include burning fossil fuels like coal or natural gas, harnessing renewable sources such as wind or solar power, using nuclear reactions in nuclear power plants, and generating electricity through hydropower by harnessing the energy of flowing water. Each method has its own advantages and disadvantages in terms of cost, environmental impact, and reliability.
What is the advantages of producing electricity using energy from the sun?
Producing electricity from the sun (solar energy) is a renewable and clean energy source that does not produce greenhouse gas emissions. It can help to reduce dependence on fossil fuels, lower electricity bills in the long term, and increase energy independence.
What are the advantages and disadvantages of using Thermal energy?
Thermal energy is essential in producing electricity, in industrial processes like oil refining, and in home heating, to think of just three applications. Disadvantages include producing greenhouse gases (except in nuclear heating),
What are the advantages of fossil fuel hydroelectricity solar energy?
Fossil Fuel Advantages: -Usually cheap electricity -Already infrastructure, power plants already operating -For oil/coal/natural gas producing countries, exporting can bring in money -Power plants able to produce high electricity output reliably Disadvantages: -Carbon emissions contribute to climate change -Finite resources -Especially w/ oil and gas, price fluctuation Hydroelectricity Advantages: -Usually cheap electricity -High electricity output -No carbon emissions -Relatively reliable Disadvantages: -Dams can flood large areas, forcing people/animals to move away -Dams can disrupt fish breeding areas -Somewhat unreliable (winter can = frozen rivers, drought = not much flow) Solar Energy Advantages: -No carbon emissions -Little maintenance -High potential output -Rapidly improving technology Disadvantages: -Currently costs a lot more than hydro or coal/gas electricity -Can take up a lot of land -Currently has low efficiency of converting sunlight to electricity -Production of panels can emit a little harmful non-carbon emissions
What are the advantages of all power stations producing electricity at the same frequency?
Time to audition with Andre " why don't you remember" xx Feeling very nervous xxx
What are the advantages and disadvantages of using heat producing light bulbs in comparison to energy-efficient alternatives?
Advantages of using heat-producing light bulbs include lower upfront cost and familiarity. Disadvantages include higher energy consumption, shorter lifespan, and potential fire hazards. Energy-efficient alternatives, such as LED bulbs, have higher upfront cost but offer longer lifespan, lower energy consumption, and reduced fire risk.
