Bright idea: Gaza teen generates electricity from candles to overcome power cuts (VIDEO) — RT Viral

Faced with regular blackouts, Shahd Abu Lebda, 16, told New China TV that she “depends on the principle that ‘a person in need will find a way’ – which pushed me towards inventing a device that generates electric charges for smart mobile phones from the energy of heat that comes from candles.”
The teen started the project after attending a course on creative thinking, Lebda’s invention has received a mixed reaction from social media users.......

Renewable energy made up record 21.7% of national electricity market in October | Environment | The Guardian

     Australia’s renewable energy sector hit a record in October, with 21.7% of electricity in the national electricity market coming from renewables, according to the latest Cedex report.
That represents the biggest proportion of any month since the data was made available by the Australian Energy Market Operator in 2005, according to the report from the engineering consultants Pitt&Sherry and the Australia Institute.

The high proportion of renewables contributed to a drop in emissions from the national electricity market – 0.8% less than a year earlier, meaning they had returned to May 2014 levels.

In the full year to October, renewable energy accounted for 14.7% of supply to the national electricity market, which encompasses the eastern states and South Australia. The lead author of the report, Hugh Saddler from Pitt&Sherry, said that was the biggest share since 1982, when demand was much lower and was satisfied by a lot of hydro......

The actual father of electricity | EDN

 Recently, while rummaging through the antique book section at my local bookstore, I came across Applied Electrical Measurements, written by Isaac F. Kinnard and copyrighted in 1956 by the General Electric Company. Being a geek for all things that make measurements possible I was giddy to add it to my library...........

55 Interesting Facts about Energy- Randomhistory.com

1. Only 10% of energy in a light bulb is used to create light. Ninety percent of a light bulb’s energy creates heat. Compact fluorescent light bulbs (CFLs), on the other hand, use about 80% less electricity than conventional bulbs and last up to 12 times as long.^g
2. Refrigerators in the U.S. consume about the same energy as 25 large power plants produce each year.^e
3. There are two basic groups of energy: renewable energy (biomass, geothermal, solar, water, and wind power) and nonrenewable (fossil fuels coal, oil, natural gas, nuclear). Three quarters of the world’s energy is generated by burning fossil fuels.^h
4. Enough sunlight reaches the earth’s surface each minute to satisfy the world’s energy demands—for an entire year.^d
5. The amount of energy Americans use doubles every 20 years.^g

'Plant Lamp' Draws Electricity from Soil -Discovery.com

Inspired by real and immediate problems in remote areas of the country, researchers at Peru’s Universidad de Ingeniería y Tecnología (UTEC) have developed a remarkable piece of technology — a low-cost LED lamp that uses plants and soil as its batteries.

The delightfully named Plantalámpara — or “plant lamp” — technically draws its power from microorganisms in the soil that are released by plants as they grow.

What is dirty Electricity ? - source Care2.com

Dirty electricity is a growing issue that can be easily misunderstood due to its complexity.

To help clear up any confusion, here are some answers to common questions about dirty electricity.

What is dirty electricity?

Electricity enters homes and other buildings at a constant frequency, typically 50 or 60 hertz (Hz,) depending on which country you live in. This is considered “clean” energy as it enters your home.

The problem starts when the electricity reaches appliances, computers or other electronic devices. Many of these devices require a transformer to convert the voltage and/or current, which disrupts the flow of electricity.

These power disruptions create irregular, high frequency surges of “dirty” electricity that travel along a building’s normal wiring, which should only contain 50 or 60 Hz electricity. The surges are also known as high frequency voltage transients.

Is dirty electricity harmful to our health?

Electrical wires and any devices that use electricity emit electromagnetic fields (EMF), also known as electromagnetic radiation (EMR). These fields will easily pass through most common materials. They are strongest close to the source and diminish with distance.
