Hydroelectric Power Generation

How does Hydroelectric Power Generation work:In hydroelectricity water potential energy works with gravitational forces. Power plants are generally built near attached waterfalls, where enough river or seasonal rain water reserved available and the kinetic energy is the greatest. To control the flow of water some time dams are required to build. When water released from the reservoir it flows down with heavy forces which rotate the turbine where generator is shafted with it generate electricity. After the water has passed through the turbine, it’s returned to the river. This power generating process is very much eco-friendly and harmless for environment compared to thermal power plant. Generating cost also the lowest in the typical power generating process.
History of Hydro Power:Ancient people is learned to use hydro-power grinding flour and other tasks. Near about 1770 AD, French engineer Bernard de Belidor architected some technique to use hydro-power in horizontal and vertical-axis…

Wind Turbine for Green Power

History of Wind Power Generation:In early, people learn to use wind as a power sources, sailing boats or ships have been using wind power for at least 5,500 years. In 17th century BC, the Babylonian emperor Hammurabi used wind power for irrigation work. Greek engineer Heron of Alexandria used wind to drive wheel to power for a machine in 1st century AD, Ancient Tibet and China also learned to use wind power since 4th century for speeding grain crushing and water pumping.

Development of Wind Power:From antiquity, middle-ages to modern 21th century; using of wind power changed widely, modern technology shaping wind power to generate electricity. In early 20th century, Denmark did remarkable development in wind power to produce electricity, by 1908 there were 72 wind-driven electric generator having capacity 5kW to 25kW.  A gigantic change took place in 1978; multi megawatt wind turbine was constructed for first time. Now for magic action of modern technology many multinational companies…

Green Energy Generation without Carbon Dioxide Emission!

Green Energy Generation without Carbon Dioxide Emission is Importance Nowadays: We aware, most of the power plants are emitting huge amount of carbon-dioxide every day all over the world. This carbon-dioxide imposes negative impact on our environment and greenhouse gases. We cannot think without electricity for a single moment, but we everybody hardly desire carbon-dioxide free system which now days called “clean” or “green”. For long time scientists are trying to go ‘green electricity’. What do you think about Green Energy? Alternative is fossil fuel, a broad of solar panel, or a field of pure white turbines? Perhaps; but have you been ever think a bucket of bacteria? Yes, now scientists are thinking Cyanobacteria may help us to generate clean or green electricity.
Cyanobacteria:You may hear to as blue-green algae or blue-green bacteria which existing from more than 3 billion years. Cyanobacteria exist in all environments, from the very hospitable to the unimaginable, from the hotspot …

Green Electricity for Future Generation

Green Electricity for Future Generation We, everyone aware our primary methods of electricity generation are harming our environment seriously. So it’s time to thinking for alternative power source.
Large number of power generation, thermal based facilities are using coal, oil or gas which cause of leading source of carbon dioxide. This carbon dioxide is affecting our greenhouse gas which directly linked to climate change. Thermal or Fossil fuel-based electricity generation is also a major source of nitrogen-oxides, sulpher-dioxide, and heavy metal- mercury, lead, and cadmium etc emission into environment and gives rise to respiratory dieses.
Thermal power plant leaves ash & smoke is pouring negative impact on local ecosystems, nuclear power leaves a legacy of radioactive waste for future generations and posing potential safety hazards today.
Alternative Source of Electricity:  Green electricity may comes from  blending wind, harvesting sunlight, beating tidal waves, collecting geo-the…

What is Energy

We are surrounded by Energy.  Energy is everywhere and it surrounds us; but we can’t touch it and also can’t measure its mass, because it is mass less. However, we can see and feel the effects of energy on many materials.
The word energy came from the Greek Energeia, meaning in or at work.
Basic concept of energy: Energy is the ability or capability to do work; Energy cannot be created or destroyed.
We cannot create or destroyed any energy, for our use we only can change the form or state of energy from one into another.
In the language of physical science, energy means the ability or capability to do work.  Work means a change in position, speed, state, or form of matter.  Therefore, energy is the capacity to change matter.
According to the law of conservation of energy, the total energy of a system remains constant, though energy may transform into another form. Two billiard balls colliding, for example, may come to rest, with the resulting energy becoming sound and perhaps a bit of heat…
