The wind speed has been measured as 5.7 m/s at 1.2 m of elevation. What would you expect the wind speed to be at 80.8 m of elevation? (answer in m/s)

How much coal combustion (in kg) would be required to release the same amount of energy as 1 kg of mass defect? (Use the following link to define the energy content of coal).

Note: In 2021 Canada used 19 million tonnes of coal for electricity generation!

Combined heat and power (CHP) units

Solar photovoltaic panels

By what factor would you expect the maximum power for a water turbine to be greater than an identical wind turbine? 

what power is available in a flow of water with velocity of 2.8 m/s in a circular channel with diameter 10.6 m (in W)? You may assume the density of water to be 1000 kg/m³.

how much power (in W) could we hope to generate when a flow of water with velocity of 2.8 m/s drives a turbine with diameter of 10.6 m. You may assume the density of water to be 1000 kg/m³.

How much energy (in MJ) is released when there is 1 kg of mass defect? You can simplify the speed of light to be 300000000 m/s. Always check your units!

The wind speed has been measured as 12.1 m/s at 0.4 m of elevation. What would you expect the wind speed to be at 73.5 m of elevation? (answer in m/s)

compared to other low-GHG technologies like wind, hydropower (reservoir), hydropower (run-of-river), and nuclear, how does solar photovoltaic rank in terms of life-cycle GHG emissions?
