Electric cars reduce greenhouse gas emissions, but electric cars still are responsible for some greenhouse gas emissions...

Electric cars reduce greenhouse gas emissions, but electric cars still are responsible for some greenhouse gas emissions. A. Calculate the grams of CO2 per km travelled for an internal combustion engine car if the car gets 32 miles per gallon (13.5 km per L). The carbon intensity of refined gasoline is 96.86 g CO2/MJ. The energy density of gasoline is given in Problem 2, Part B. B. Calculate the grams of CO2 per km travelled for electric car if the car gets 4 km per kWh (typical of today’s all-electric vehicles). Assume the electricity comes from a coal-fired power plant operating at 30% efficiency. Assume coal has a carbon intensity of 90 g CO2/MJ. C. What is the annual reduction in carbon dioxide emissions in metric tons if one million cars similar to those in Part A are replaced with one million cars similar to those in Part B? Assume 12,000 miles (19,200 km) per year.

    One possible worry about electric cars is that they're currently powered by dirty electricity. But proponents, as quoted in this story on the issue, claim that they're still cleaner than traditional cars even if their electricity comes from fossil fuels because of how efficient large-scale electricity production is and how efficient electric motors are. Let's investigate for ourselves. 1.) Let's look at the worst-case scenario, an electric car powered entirely by electricity from coal. Assume the car is a Nissan...

    Write a C program (intro level) that calculate car emmisions 4.2 Car emissions Gas-powered cars emit various types of pollutants: 1. Carbon monoxide (CO), an odorless and colorless gas that is highly poisonous if breathed by humans. 2. Hydrocarbons (HC), burned or partially burned raw fuel, which are a major contributor to smog. 3. Nitrogen oxides (NOx), which is generated when nitrogen in the air reacts with oxygen at the high temperature and pressure inside the engine. 4. Non-methane hydrocarbons...

    2. The electric vehicle Tesla Model S has a drag coefficient of 0.24, a mass of 2100 kg, and a frontal area of 2.4 m2. The coefficient of rolling resistance of its tires is 0.01. Recall the density of air at sea level is 1.3 kg/m3. How much kinetic energy is required to overcome rolling resistance and air resistance (drag) at Autobahn speeds of 180 km/hr for a 200 km trip? How much useful energy (in MJ) and money (in...
