  • Farmers have been using wind energy for many years to pump water from wells using windmills like the one on the right
  • When a boat lifts a sail, it is using wind energy to push it through the water. This is one form of work.

  • Wind is also used to turn large grinding stones to grind wheat or corn, just like a water wheel is turned by water power.
  • n Holland, windmills have been used for centuries to pump water from low-lying areas.
  • Wind can be used to do work. The kinetic energy of the wind can be changed into other forms of energy, either mechanical energy or electrical energy
  • Blowing wind spins the blades on a wind turbine – just like a large toy pinwheel.
  • If the wind gets too high, the turbine has a brake that will keep the blades from turning too fast and being damaged.
  • You can use a single smaller wind turbine to power a home or a school. A small turbine makes enough energy for a house.

    "The blades of the turbine are attached to a hub that is mounted on a turning shaft. The shaft goes through a gear transmission box where the turning speed is increased. The transmission is attached to a high speed shaft which turns a generator that makes electricity."

    There are many renewable energy sources out there right now, continuing to develop in their technology and production. All of these resources have very high capital cost inputs that are hard to compete with cheap natural gas. However, these new resources are abundant, some even limitless, and unlike natural gas, fuels and oil, they will be around for a long time.
