Wind and solar energy.

In a world where natural resources such as petroleum are depleting, we have to find alternative fuels to run our motorised vehicles and household appliances.

I watched a documentary about harnessing the wind to provide energy for a house. One man installed a very huge windmills that turn a turbine to produce enough electricity to run his air-conditioner, fridge, stove and son. This type of energy is pollution free and environment-friendly.

Another town installed solar panels to trap the sun's light to do the same job as above. This time the whole village gets the supply of electricity. Again, solar energy is environment-friendly too.

If all of us can generate energy as above, the problems of fuel depletion and air pollution may be solved one day.
