Here’s where 620 million people in Africa live without electricity

Africa 1

The International Energy Agency has come out with an in-depth analysis of Africa’s energy sector.  According to the IEA report, there are 620 million people in sub-Saharan Africa who don’t have any electricity at all — and fixing that could require burning a lot more fossil fuels.

100% of the world’s power could be supplied by renewables by 2050


Even though wind power uses up to 14 times more iron, the world wins on a switch to low-carbon energy.

A global low-carbon energy economy could actually double electricity supply by 2050, while also reducing air and water pollution, according to new research. The first ever global life-cycle assessment of clean energy sources shows that a renewable system could supply the world’s entire electricity needs by mid-century, writes Tim Radford.

Graphene supercapacitors could provide energy for flexible electronics


A research team has created an energy storage device that is highly flexible and stretchy.

How long would your battery last if your phone was always awake and processing data? Would the battery last three hours? One hour? The next generation of electronics will require that kind of always-on energy consumption, but our current batteries are far from powerful enough to accommodate that.

Maine to harness wave power to generate electricity

wave power

Maine is geared to join hands with other few states to generate electricity from tidal waves.

With increasing global warming and increasing awareness of other environmental hazards, more and more people across the world are focusing on harnessing natural sources of energy like wind energy. Wave power is a renewable source of energy and is available in abundance. Wind energy provides clean fuel which is environment friendly and does not produce greenhouse gases. And to capitalize on its greener attribute, we have been utilizing ocean waves for centuries.

Airlight Energy and IBM’s new sunflower-shaped solar concentrators produce energy and fresh water


High Concentration PhotoVoltaic Thermal (HCPVT)

A cutting-edge solar system that resembles a 10-meter-high sunflower has just been unveiled by IBM Research and Swiss solar technology company Airlight Energy. The High Concentration PhotoVoltaic Thermal (HCPVT) system can concentrate the sun’s radiation 2,000 times and convert 80 percent of it into useful energy, generating up to 12 kilowatts of electrical power and 20 kilowatts of heat on a sunny day—enough to power several average homes. It can also produce clean, fresh water as a result of the process used to cool the solar cells. (Video)

We are headed into an era of unlimited and free clean energy

clean energy

Inexpensive renewable sources will provide more energy than the world needs in less than 20 years.

Leading consultants were skeptical about cellular phones in the 1980′s. McKinsey & Co. noted that the handsets were heavy, batteries didn’t last long, coverage was patchy, and the cost per minute was exorbitant. It predicted that in 20 years the total market size would be about 900,000 units and advised AT&T to pull out.
