Wind turbine and biogas Plant comparison

Wind turbine and biogas Plant comparison 

As the title of this post is indicating the topic. biogas plant and wind turbine Both are source of renewable energy wind turbines primary purpose is to generate electricity, biogas plant can also generate electricity but the method of generating electricity is different to wind turbine 

How wind turbine can generate electricity?

Wind turbine consist of Blades, Router, gearbox, alternator or generator, tail, pylon or pole

Blades are aerodynamically and rotate shaft of generator by wind power. Generator generate electricity its can be store at batteries or can use directly

Wind turbines commonly are two types 1st is HAWT (horizontal axis wind turbine) 2^nd type is VAWT (vertical axis wind turbine) HAWT are more efficient then VAWT in many countries HAWT are installed HAWT can generate 100 watts to few mega watts. VAWTs are not affected by the direction of the wind, which is useful in areas where the wind changes direction frequently and rapidly. Unlike traditional horizontal axis wind turbines, a yaw mechanism is not needed to turn the wind turbine towards the wind. The VAWT is bird and wildlife friendly.

Environmental effects of wind turbine are noticeable big disadvantage of wind turbine is notice, birds killing and less age need regular maintenance for domestic and industrial wind turbine as well

Biogas Plant structure and how its work?

Biogas plant also called bio-digester, bio-methane plant and gobar gas plant locally called in Pakistan and India

Biogas plants are many type but two type of biogas plant are very common 1sr is fixed dome biogas plant and 2^nd is movable dome biogas plant, 3^rd type biogas plant also is very common called portable biogas plant or plastic drum biogas plant. Biogas plant digester consist of dome, digester tank, gas storage tank, inlet and outlet, digester tank digest the biological waist anaerobically with the help of microbe (biogas bacteria) the end product of a biogas. Biogas contains methane 60 to 70 % and 30 % of other gases. Methane gas are flammable and that can run gasoline generator to produce electricity also can use heating and cooking

Biogas are environmental friendly its reduce carbon imitation and green houses gases, biogas plant might be small size 1 meter cube to 100’s of meter cubic at industrial level

Wind turbine are mostly use in these countries are Germany, Denmark, Italy Spain. Biogas plants in India , china, Bangladesh , Pakistan, Philippine  etc are very common and increasing day by day
