How it works – Nuclear power plants

17% of the world’s energy is provided by the nuclear power plants. Some countries have more dependency on nuclear power than others, for e.g. France has 75% of its energy in the form of nuclear energy as is said by the International Atomic Energy Agency. 15% of the power supplied to the United States is […]

Wave energy

The ocean is a source of vast amounts of energy; the water carries with it huge amounts of potential and kinetic energy which is harnessed can solve the world’s energy problems twice over. Wave energy is a concept where the energy from the ocean is meant to be utilized. The techniques developed are
1)    Open […]

Geothermal Events Expected to Draw Record Crowd

The geothermal power industry’s largest show, the Geothermal Energy Association’s Trade Show is now a huge hit, it is expected to bring in a record no crowd this year and preparations are being made for the same. This annual meet is help in consonance with the Geothermal Resources Council Annual Meeting, and the crowds are […]

Fission energy

What is Fission energy?”Fission is a nuclear process in which a heavy nucleus splits into two smaller nuclei.” This is the definition given for the energy generation process called fission energy. Fission energy is produced when the electrostatic forces inside the atom are overcome. An atom of larger size has more electrostatic repulsion between the […]

Ocean thermal energy conversion

Energy is one of our primary needs, and the most primary of all those needs is the need for an alternate source of energy that is nonpolluting and does not eat into our fossil fuel reserves. This is where these technologies come into play.
What exactly is Ocean thermal energy conversion?
The main line of thought behind […]

How is wind energy stored?

The mechanical energy can easily be converted into electrical energy by the rotation of the shaft of the wind turbine in direct current or DC form. From there this form of energy is converted from DC to AC form of energy.  This is a very expensive option in the way of costs as well as […]

Ground water recharge affected by climate change

There could be a serious setback to the ecological protection measures if the levels of carbon dioxide continue to rise at the rate it is currently. The carbon dioxide increase can adversely affect the weather, air and vegetation, that are common knowledge, but now another graver problem is coming to the fore, the increase in […]

Factors to keep in mind while Building a Windmill

The most important things to keep in mind while building a windmill are
A) Location:-
The energy of the wind is usually on the higher side and is more useful to generation of energy on the seashores or at the sides of large lakes or water bodies thus making these places ideal for setting up of a […]

Windmill Shrouds and their use

Shrouds like those of jet engines cover some turbines. The use of a shroud is that the wind gets channeled.  .
The equation for the power harnessed by a shrouded wind turbine is:
P(Pe) = ( QT ((p + (k)  where P is the power,
Pe is the power extracted, ( is the turbine efficiency, QT is the  […]

Types of Windmills

1) Aeration Windmill
This is the kind of windmill used for the aeration of a pond or for the pumping of water out of a small water body to serve your garden or animals. The maximum depth that this can pump water from is 15m.
2) Aermotor Windmill
Manufactures since 1888 these are the standard for windmills, it […]
