What energy source should we pursue and why? Also, which one should we stay away from and why?

Question: Please explain why your car engine is generally less efficient when its ignition temperature is lower. *Please be thorough with the answer.

Which of the following is not a future consequence of nuclear energy use? O Increased safety and innovation O Partial reuse of energy fuel rods O Smaller nuclear power facilities O Higher costs for new plant designs

I'm confused on problem # 32 because I've searched this answer twice and one expert said the answer was 31.97 kJ and another said the answer was 2.90 x 10^10 but I got 2.90 x 10^7. Please help thank you!

Is creating energy and electricity through nuclear power plants, a sustainable energy source, in order to augment reliance on fossil fuels an ethical idea when compared to other technologies, such as solar, wind, and natural gas? If so, on what basis? If not, why, and is there anything that could bolster its ethical production?

Assess the mechanisms of energy transfer involved in generating the electrical power supply in Nuclear power plant.

1. Where do you think the 70% (gasoline) and the other 50% (diesel) of the energies of the two engines goes? Use any past experience you have had with engines of any kind to hypothesize.

Estimate the greenhouse gas emissions from power production for the following threescenarios. Focus on the greenhouse gas emissions associated with theoperational energy, not the greenhouse gas emissions associated with the manufacture of theproduct or end of life processes.The hourly load demand for a home is given.1)  All power during an hour of up to 5 kW is drawn from a baseload coal powerplant. Any power in excess of that amount is drawn from a peaker plant running as anatural gas combined cycle power plant.2) Localized solar energy production is provided in the table on the next page.Energy demand by the house is first met by this solar generation. If the total hourlyenergy demand is below 5 kW, then any extra energy required beyond that provided bythe solar panels is drawn from a coal power plant. If the total hourly demand is above 5kW, then any extra hour demand beyond 5 kW is met by a natural gas combined cyclepower plant. No credit is given if the solar energy production…

Thermodynamics

4.) A gasoline engine takes in 1.61x10* J of heat and delivers 3700 J of work per cycle, The heat is obtained by burning gasoline with a heat of combustion of 4.60x10*2. (a) What is the thermal efficiency2 (b) How much heat is discarded in each cycle? (c) What mass of fuel is burned in each cycle? (d) If the engine goes through 60.0 cycles per second, what is its power output in kilowatts and in horsepower? acpordance with Section 185.
