What is AC Power

An electrical current whose magnitude and direction varies continuously and sinusoidally. AC is the form in which electricity is delivered to businesses and residences. It can be thought of as "standard" electrical power.

What is a a Battery ?

Two or more electrochemical cells enclosed in a container and electrically interconnected in an appropriate series/parallel arrangement to provide the required operating voltage and current levels. Under common usage, the term battery also applies to a single cell if it constitutes the entire electrochemical storage system.

Africa's Solar ability

Which country boasts the world's fastest growing clean energy investment? Germany? No. United States? Think again.

Jumping from a few hundred million dollars to $5.7 billion, South Africa recorded last year the world's highest growth in renewable energy investment, according to the (UNEP).

The spectacular surge, led largely by investments in solar power projects, comes as South Africa moves to reduce its dependency on coal, that's around 86  of total energy. To achieve that, the country has set the advaned target of generating 18 gigawatts (GW) of clean energy by 2030.

As a result, a series of investments have trickled into the country, including Google's first foray into Africa's solar power market. The internet giant, which has spent more than $1 billion in renewable energy programs in the United States and Europe in recent years, announced in late May its decision to back the JPP (Jasper Power Project) a 96 MW solar photovoltaic (PV) plant in Northern Cape, with a $12 million investment.

Pakistan has potential in Solar Energy sector

Secretary General Renewable Energy Association of Pakistan Iftikhar Qaisrani has said Pakistan has 2.9 million megawatt of solar energy potential besides photovoltaic opportunity. Talking to Radio Pakistan, Iftikhar Qaisrani said that Pakistan is among a few fortunate countries that have a lot of potential of alterative and renewable energy production.  Pakistan has well-defined wind energy corridors which are about 340 thousand megawatt. Pakistan also has the natural resources of bio-fuel and cogeneration.
Iftikhar Qaisrani expressed hope that the government of Nawaz Sharif will capitalize on the renewable energy resources.He opined that Pakistan will be in a position to export energy besides meeting its own needs after utilizing these vast opportunities of alternative energy resources.

What is Failment

A coil of tungsten wire suspended in a vacuum or inert gas-filled bulb. When electricity flows thru the tungsten "filament" it radiates energy in the form of heat and light. This is the basic operation of inefficient incandescent lamps.

What is Electron

An elementary particle of an atom with a negative electrical charge and a mass of 1/1837 of a proton. Electrons surround the positively charged protons in the nucleus of an atom and the number of electrons determine the atomic element. Elements that loose electrons easily make good conductors and elements whose electrons are tightly bound together make good insulators. It is this movement of electrons which is the electric current in circuits.

SolarTech Expo Japan

SolarTech Expo Japan 2013, a strictly B2B conference and exhibition will be held in Tokyo city on 28-29 October 2013. Located in the networking area exhibition will hold 25 exhibition stands where leading solar energy technology companies will showcase their technologies and solutions for the industry.
