Study Notes
Renewable Energy Sources
- The ultimate source of all renewable energy except tidal and geothermal power is the sun.
Wind Energy
- 2-3% of solar energy falling on the earth's surface is converted to wind energy.
- The speed of the wind is the primary factor determining the kinetic energy in the wind.
- Wind turbines are used to convert wind energy to electrical energy.
- The global wind market has an approximate annual growth rate of 20-30%.
- The sun is the primary source of wind energy, as it heats the earth's surface unevenly, causing air to rise and create winds.
- The speed of the wind is the factor that determines the kinetic energy in the wind.
- Wind turbines are used to convert wind energy to electrical energy.
- Government incentives and declining costs are the primary drivers of the annual growth rate of the global wind market.
