Sources of Power in the Farm - Renewable Energy

Flashcards cover key vocabulary related to renewable energy sources, specifically wind, hydro, and biomass energy, as presented in lecture notes.

Wind Power

Utilization of wind energy for various applications such as electricity generation, pumping water, and propelling ships.

Bangui Wind Farm

A prominent wind farm located in Ilocos Norte, Philippines, known for harnessing wind energy.

Pililla Wind Farm

A wind farm situated in Rizal, Philippines, contributing to renewable energy generation.

Sustainable Energy

Energy that is continuously available and will never run out, such as wind energy.

Vertical-Axis Turbines

Wind turbines with blades oriented vertically, enabling them to operate in variable wind conditions.

Savonius Windmill

A type of vertical-axis turbine characterized by its drag force design, suitable for low wind speeds.

Darrieus Windmill

A vertical-axis turbine that operates on aerodynamic lift, achieving higher efficiency than Savonius turbines.

Torque Coefficient (Ct)

The ratio between the torque at the rotor and the reference torque in wind turbines.

Power Coefficient (Cp)

The ratio of actual power generated by the turbine to the theoretical wind power available.

Hydropower

Energy generated from water flow, including full-scale hydro, small hydro, mini-hydro, and micro-hydro systems.

Biomass Energy

Energy derived from organic materials, including wood, agricultural residues, and animal waste.

Stoichiometric Air-fuel Ratio

The mass ratio of air needed to completely combust a fuel.

Solar Energy

Energy harnessed from the sun, utilized in solar water heating, cooking, and photovoltaic applications.

Tip-Speed Ratio (TSR)

The ratio of circumferential velocity at the tip of the rotor to the free stream wind velocity.

Kinetic Energy of Wind

The energy produced by wind, calculated as E = 2365 [mg] V^2, where m is the mass of air and V is wind velocity.

Drag Force

A force acting opposite to the relative motion of an object moving through a fluid, utilized in certain wind turbine designs.

Aerodynamic Lift

The force that opposes the weight of an object and holds it in the air, critical for turbine function.
