Much of the U.S. electricity is generated in thermal generating stations that burn fossil fuels such as coal and natural gas. The use of solar-powered generating stations is expected to increase over the next decade and replace older fossil-fuel generating stations. What impact might this change have on greenhouse gas emissions?

Top 7 Renewable Energy Sources in 2020 SOLAR ENERGY Wind ENERGY BIO OCEAN ENERGY HYFROGEN ENERGY GEOTHERMAL ENERGY POWER HYDRO POWER 13. What sectors produce the most carbon dioxide emissions? (Write in order #1, #2..)|

The chart shows average CO2 emissions for fossil fuel vehicles (gasoline, diesel, and hybrid gas‑electric), as well as electric vehicles. The ordinate is mg CO2 per mile driven per pound mass of the vehicle (called curb weight). For electric vehicles, CO2 emission varies in U.S. states because of the mix of fuels used to generate electricity. If electricity came entirely from solar power, there would be little CO2 associated with its production. California has the lowest CO2 emission for producing electricity and Ohio has the highest because it depends heavily on coal‑fired power plants. The chart does not include CO2 emission from manufacturing vehicles. When normalized for distance driven by each kind of vehicle before it is scrapped, CO2 emission associated with manufacturing electric vehicles is estimated to be 25–75% greater than CO2 emission associated with manufacturing gasoline and diesel vehicles. If manufacturing were included, CO2 emission associated with electric vehicles…

4. Photochemical smog is a type of air pollution in the troposphere of our planet produced when sunlight acts upon motor vehicle exhaust gases to form harmful substances such as ozone (O3). For example, nitrogen dioxide (NO2) reacts with atmospheric oxygen (O2) in the presence of light to produce ozone (O3) and nitrogen monoxide (NO).

Please help me with this chemistry question, please include citations/references. Thank you! Discuss and explain at least two problems associated with the burning of fossil fuels. Is fossil fuel finite? What is its origin? What are two examples of some environmentally friendly renewable energy resources?

The citizens of the world burn the fossil fuel equivalent of 7 * 1012 kg of petroleum per year. Assume that all of this petroleum is in the form of octane (C8H18) and calculate how much CO2 (in kg) the world produces from fossil fuel combustion per year. (Hint: Begin by writing a balanced equation for the combustion of octane.) If the atmosphere currently contains approximately3 * 1015 kg of CO2, how long will it take for the world’s fossil fuel combustion to double the amount of atmospheric carbon dioxide?

1. What are the three main types of greenhouse gases, what are their respective characterization factors or global warming potential? 2. What is meant by the efficiency of a solar panel (PV) and what are the implications for a solar farm? 3. How is energy extracted from wind and what are the implications for a wind farm? 4. For a wind turbine, what is the impact of the wind speed on the electricity production and how does the design of the wind turbine dictate its efficiency? What control strategies can be used to optimise the performance of wind turbines? How can energy be extracted geothermally. Explain how geothermal energy can be utilised to contribute towards heat demand and what is the role of co-produced water. 5. 6.

Write down some of the benefits and drawbacks of going green. (This question is related to green chemistry in industry) Benefits: Drawkbacks:

reading: The accelerometer keeps track of how quickly the speed of your vehicle is changing. When your car hits another car—or wall or telephone pole or deer—the accelerometer triggers the circuit. The circuit then sends an electrical current through the heating element, which is kind of like the ones in your toaster, except it heats up a whole lot quicker. This ignites the charge which prompts a decomposition reaction that fills the deflated nylon airbag (packed in your steering column, dashboard or car door) at about 200 miles per hour. The whole process takes a mere 1/25 of a second. The bag itself has tiny holes that begin releasing the gas as soon as it’s filled. The goal is for the bag to be deflating by time your head hits it. That way it absorbs the impact, rather than your head bouncing back off the fully inflated airbag and causing you the sort of whiplash that could break your neck. Sometimes a puff of white powder comes out of the bag. That’s cornstarch or talcum powder to…

Hello, please answer the question. Please show all your work. Thank you.

Does it seem logical that the burning of fossil fuels and the addition of carbon dioxide to the atmosphere leads to the warming of the Earth? Why or why not?

When ozone levels in urban area reach unhealthy levels, residents are typically urged to avoid refuelingtheir cars during daylight hours. Explain how this might help to reduce smog formation?

The U.S. is one of several countries committed to reaching “net-zero” carbon emissions by 2050. This means that by 2050, all carbon dioxide emissions must be matched by the amount of carbon dioxide removed from the air. Why is it essential for all countries in the world to meet carbon reduction commitments like this
