- Once set up, wind energy uses kinetic energy from wind for free forever, enabling you to utilize the energy of a force of nature that has a total potential of power generation larger than the current power consumption from all the power sources combined.

- Wind energy is environment friendly and there are no carbon emissions or environmental hazards produced during power generation, as is the case with thermal energy.

- Wind energy is more efficient than solar energy if provided the right capacity and conditions. A small wind turbine can create as much energy as 5 to 10 solar panels combined.

- New designs and mechanism are being introduced through constant research to ensure the better use of wind turbines. Such has been the case in its improvement in output and noise reduction from what we used to get 5 to 10 years back.


The performance of wind mills depends on wind, weather and geography.

- Wind energy, comparatively to solar panels, requires greater maintenance due to moving parts and you would have to replace the bearings of the turbine once every 5 years.

- Wind mills can be a potential threat to the lives of flying animals like birds and bats.

- Wind mills are immediately noticed at a particular location, and their visual impact may affect the desirability and property values in the neighborhood, which could create a hurdle to its installation in the first place.


The pros are doesn't not create pollution or radio active wastes. They have less impact on the environment.it also can be used to provide electricity to each individual home. can also be used in a large scale for a large number of people. it is reusable.

The cons are it can be damaged in natural disaster such as thunder storms and tornadoes. The turbines can hit birds that try to fly between them. The blades can create a sound when it moves so can be a nuisance to people living near it

hydro power






The pros are it is reusable energy. Dams can store energy from rain water or river in case of any natural disaster such as a drought there can still be water left in the dam.

The cons are it can change the natural changes and seasonal changes that occur in the river.Dams are expensive to build.If a drought occurred may dry up and become useless>

we did this it was preety awsum to find out that even potatoes have voltage in them.with just puting one nail and copper in u can test for voltage which gives a reading of about 0.002 or asumthing like that it was pretty awsum to find out about different soures we use to get power in the country
