A typical large coal fired electric power plant produces 1,200MW of electricity by burning fuel with energy content of 3,000 MW. Three hundred and forty (340) MW are lost as heat up the smokestack leaving the rest to drive a generator to produce electricity. However, the thermal efficiency of the turbine is only 45%. That is 45% of the remaining power goes to drive the generator, and 55% is waste heat that must be removed by cooling water. Assume that...

A power plant produces electricity by burning coal and converting water into steam. The pressurized steam makes a turbine turn, which produces electricity. The plant has a power output of 380 MW and operates at an overall efficiency of 31%. How much coal does the plant burn in one minute (60 s)? State your answer in kilograms. (1 kg of coal yields 30 MJ energy)

You place your lunch leftovers in the refrigerator. Suppose the refrigerator needs to remove 9.8700E+3 J of thermal energy from your lunch to cool it to the temperature of the inside of the refrigerator. In the meantime, this means the refrigerator produces 1.3702E+4 J of thermal energy that it expels into the kitchen as a result. What is the total work done by the compressor motor in the refrigerator?(Ignore any thermal loses due to friction in the motor.) 3.832×103 J...

Problem 2: Pedal Power
Many villages in the developing world lack access to electricity.
One proposed solution is the ‘Free Electric’ bicycle, which is a
stationary bike hooked up to a generator and battery. Pedaling the
bike powers the generator, which creates electricity that is stored
in the battery. The inventor claims that 1 hour on the bike can
produce a whole day of electricity. Let’s put it to the test!
Assume the following: The human body is 25%...

WHAT YOU CAN DO ABOUT CLIMATE CHANGE
The EPA has produced a guide about what individuals can do to help
reduce their contributions to climate change. Changes in the home,
yard, and on the road can reduce greenhouse gases and save money.
EPA notes 16 simple steps individuals can take to reduce greenhouse
gas emissions, summarized below.
