Electricity is the flow of electrical power or charge. It is both a basic part of nature and one of our most widely used forms of energy.
Electricity is actually a secondary energy source, also referred to as an energy carrier. That means that we get electricity from the conversion of other sources of energy, such as coal, nuclear, or solar energy. These are called primary sources. The energy sources we use to make electricity can be renewable or non-renewable, but electricity itself is neither renewable or nonrenewable.

Electric airplane progression
More examples of popular electric RC airplanes
The variety of electric powered planes available is vast and growing all the time. It's very easy to become overwhelmed by the choice (my eBook makes choosing easy!), but shown below are a few recommended examples of popular Ready To Fly electric rc airplanes...
The Firebird Freedom, from HobbyZone, is a very different style of airplane with a distinct pod-and-boom design. The Firebird range is a popular one with beginners to the hobby. 
This J3 Cub is a very popular scale subject and it's gentle flying characteristics and stability make it perfect for beginners. 
This attractive Super Decathlon makes a great 3 channel aerobatic trainer, its brushless motor and Li-Po power giving it excellent performance, yet the high wing design giving it the stability needed by beginner pilots. 
This Ambassador, from Megatech, follows on from the successful Freedom Flyer but features a powerful outrunner brushless motor and Li-Po battery pack. A great 4 channel trainer and suitable as an all-round electric rc 'sport' flyer.
This E-flite Apprentice 15e took electric rc trainers into a new age, being the first such RTF trainer to be sold with 2.4GHz rc technology. A very popular choice with new rc pilots looking to get serious from day one.
This scale ME Bf109G is a low-wing faster electric airplane, modeled on the famous WWII German warbird. A great plane for when you've got a few hours under your belt, these ParkZone warbirds are excellent planes. This Messerschmitt isn't available as RTF though.

An electric locomotive is a locomotive powered by electricity from an external source. Sources include overhead lines, third rail, or an on-board electricity storage device such as a battery, flywheel system, or fuel cell.
Electrically propelled locomotives with on-board fueled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine electric locomotives because the electric generator/motor combination only serves as a power transmission system.

Lightning results from the buildup and release of electrical energy between positive and negative charges between the earth and a thunderstorm. A single lightning bolt can be as hot as 50,000 degrees Fahrenheit - hotter even than the surface of the sun. This rapid heating and cooling of the air creates a shock wave which we hear as thunder. Lightning will usually strike the highest object in area. This includes trees, antennas, a boat on a lake, or a person standing in a field.

Maria Cristina Falls is a waterfall of the Agus River on the island of Mindanao. It is sometimes called the "twin falls" as the flow is separated by a rock at the brink of the waterfall.[1] It is a landmark of Iligan City, nicknamed the City of Majestic Waterfalls, because of the presence of more than 20 waterfalls in the city. It is located 9.3 kilometers away southwest of the city proper at the boundaries of Barangays Maria Cristina, Ditucalan, and Buru-un. Well-known for its natural beauty and grandeur, the 320-feet98 meters/320 feet high waterfall[3] is also the primary source of electric power for the city's industries, being harnessed by the Agus VI Hydroelectric Plant.

The guy in the video is Richard Gryzch who claims that this is the world’s first solar charged electric motorbike that can travel up to 50 miles on a full charge and hits a top speed of 9o mph.
The Solar Flyer as it’s called by Gryzch has taken him more than two years to build and to finance his project sold his other motorcycles and even a house.

Bataan Nuclear Power Plant
From Wikipedia, the free encyclopedia
Bataan Nuclear Power Plant is a nuclear power plant, completed but never fueled, on Bataan Peninsula, 100 kilometers (60 miles) west of Manila in the Philippines. It is located on a 3.57 square kilometer government reservation at Napot Point in Morong, Bataan. It was the Philippines' only attempt at building a nuclear power plant.
[edit] History
The Philippine nuclear program started in 1958 with the creation of the Philippine Atomic Energy Commission (PAEC) under Republic Act 2067.[1]
Under a regime of martial law, Philippine President Ferdinand Marcos in July 1973 announced the decision to build a nuclear power plant.[1] This was in response to the 1973 oil crisis, as the Middle East oil embargo had put a heavy strain on the Philippine economy, and Marcos believed nuclear power to be the solution to meeting the country's energy demands and decreasing dependence on imported oil.[2]
Construction on the Bataan Nuclear Power Plant began in 1976. Following the 1979 Three Mile Island accident in the United States, construction on the BNPP was stopped, and a subsequent safety inquiry into the plant revealed over 4,000 defects.[1] Among the issues raised was that it was built near major earthquake fault lines and close to the then dormant Pinatubo volcano.[2]
By 1984, when the BNPP was nearly complete, its cost had reached $2.3 billion.[2] A Westinghouse light water reactor, it was designed to produce 621 megawatts of electricity.[2]
Marcos was overthrown by the People Power Revolution in 1986. Days after the April 1986 Chernobyl disaster, the succeeding administration of President Corazon Aquino decided not to operate the plant.[1][3] Among other considerations taken were the strong opposition from Bataan residents and Philippine citizens.[1][3]
The government sued Westinghouse for overpricing and bribery but was ultimately rejected by a United States court.[4]
Debt repayment on the plant became the country's biggest single obligation, and while successive governments have looked at several proposals to convert the plant into an oil, coal, or gas-fired power station, but all have been deemed less economically attractive in the long term than the construction of new power stations.[2]
Despite never having been commissioned, the plant has remained intact, including the nuclear reactor, and has continued to be maintained.[2] The Philippine government completed paying off its obligations on the plant in April 2007, more than 30 years after construction began.[2]
On January 29, 2008, Energy Secretary Angelo Reyes announced that International Atomic Energy Agency (IAEA) 8-man team led by Akira Omoto inspected the mothballed Bataan Nuclear power station on rehabilitation prospects. In preparing their report, the IAEA made two primary recommendations. First, the power plant's status must be thoroughly evaluated by technical inspections and economic evaluations conducted by a committed group of nuclear power experts with experience in preservation management. Second, the IAEA mission advised the Philippines Government on the general requirements for starting its nuclear power program, stressing that the proper infrastructure, safety standards, and knowledge be implemented.[5] The IAEA's role did not extend to assessing whether the power plant is usable or not, or how much the plant may cost to rehabilitate.[6]

Solar Powered Cars traditionall are defined as cars which run on energy from the sun. They got their first recognision as a possible transportation method through the seriies of annual races across Australia.
This definition however is changing, in recent years of the green movement, solar power explosion now allows people to charge plugin electric vehicles (PEVs) through solar panels installed on their homes and in recent history solar panels installed on the roof of the car itself.
There is a very bright future for solar energy to power our transportation needs and we're just scratching the surface of the possibilities.

electrical safety
Electrical Safety Tips
OSHA provides numerous safety-related guidelines in its regulations for working with electrical equipment. Here’s a look at several of its tips for remaining safe, as defined in OSHA Standard 1910.
• If the insulating capability of protective equipment may be subject to damage during use, the insulating material shall be protected. (For example, an outer covering of leather is sometimes used for the protection of rubber insulating material.)
• Employees shall wear nonconductive head protection wherever there is a danger of head injury from electric shock or burns due to contact with exposed energized parts.
• Employees shall wear protective equipment for the eyes or face wherever there is danger of injury to the eyes or face from electric arcs or flashes or from flying objects resulting from electrical explosion.
• When working near exposed energized conductors or circuit parts, each employee shall use insulated tools or handling equipment if the tools or handling equipment might make contact with such conductors or parts.
• Fuse handling equipment, insulated for the circuit voltage, shall be used to remove or install fuses when the fuse terminals are energized.
