Part 2: The Power Equation and Wind as an Energy Resource (30 minutes) Review the power equation included in the reading and explain that engineers designing and developing wind turbines face the same challenges that they will in upcoming class periods as they construct a table-top wind turbine.
CHAPTER ONE - ResearchGate
The result of power output got from simulation testing and calculation using equation 2.1 are as shown in Figure 5.2. The radius of turbine blade was set at 8 metres.

Equation (10) tells us that the electromagnetic system COP is a function of its efficiency and the ratio of the environmental input power to the operator input power. If the operator input power is zero, the COP becomes infinite, as in the examples described above for a windmill, waterwheel or sailboat.

An analysis was performed in order to determine the environmental impacts of using hydrogen as an energy source versus traditional energy resources. As mentioned before RG&E gets its power from a number of different sources, some of which include coal, oil and gas. Generating power using these resources releases contaminants into the atmosphere.
