If a typical house uses 10,900 kWh per year, calculate how many houses could have their full energy needs provided for one year by the turbine above (the turbine above produces 10.5 MW per week) if it continued to operate as described for one year. Show work. thank you.
A 20 kW electric roof top A/C unit (RTU) is 10 years old, and has a COP of 2.0 . It operates at full load for 3,000 hours a year. The electric cost is $0.10 per kWh. If this to unit to be replaced with a new 20 kw, what is the minimum value of COP for the ?new unit to reach an annual savings of $1,500 3.5 4.0 4.5 Can not be determined
The information in the table below gives information about energy use in a typical house. A typical house in the United States uses about 10,900 kWh (kilowatt-hour) of electricity per year. 1 TWh (terawatt-hour) = 1 × 106 GWh (gigawatt-hour) = 1 x 10° kWh (kilowatt-hour). (c) One recent cost analysis report indicates that electricity from hydroelectric power can be produced for about $0.05 per kWh, while electricity from conventional coal-fired power plants can be produced for an average of about $0.11 per kWh. Calculate the percent change in the cost of electricity for a typical house resulting from a switch between conventional coal-fired power plants to hydroelectric power.

There was basically no electricity 150 years ago. Tesla, Edison and Faraday were experimenting and it was believed to be dangerous, so no electric anything. They used wood and coal fired brick and iron ovens and fire places. The lighting was oil and gas lamps and candles, hence the saying “Burning the midnight oil.” I have lived with little (generators and solar power) or no electricity in the deep desert in Saudi Arabia, in the mountains on expeditions and after hurricanes Irene and Maria in the Caribbean. Today fossil fuels and electricity are the foundation of our civilization. How will we continue to make electricity in the future? Any other research examples?
