Sindh Governor Dr Ishratul Ebad Khan said that the government had devised a plan to generate 10,000 megawatts of electricity from Thar coal by 2020.

The federal government had been approached for laying a transmission line to take the electricity from Thar field to the national grid, he said while presiding over a meeting on Thar coal at the Governor’s House Thursday. He said installation of transmission network is the integral part of the plan which should be ready by the time power projects are ready to generate electricity from Thar coal.

The Governor pointed out that Thar coal would be utilised to make Pakistan self-sufficient in power generation to strengthen economy and make this area the hub of the petro-chemical industry.



Africa at the Energy Crossroads Ethiopia Launches 6 Wind, 1 Geothermal Power Project

Ethiopia isn’t a country that comes up often when discussing renewable energy, but the Ethiopian Electric Power Coroporation (EEPCO) this past week announced it’s starting construction of six wind power projects and one geothermal power plant. In total, electricity generation capacity for the renewable energy projects totals more than one gigawatt (1 GW), Ethtiopian news service NewsDire reported.

The renewable energy projects are part of EEPCO’s plans to increase national electricity generation capacity five times by 2015, from a current 2000 megawatts (MW) to about 10,000 MW. Increasing electricity generation, in turn, is key to the government’s broader economic development plans.



Efflux - An integrated wind turbine structure designed to perfection

You would have heard of various wind turbine projects that run toward the generation of power by using the naturally blowing wind’s energy. This generated power is then used to run several applications that require electrical energy as an input. For that purpose, the energy is generally transported and fed into the power grid. But, here is a unique and power-packed German design for an integrated wind turbine structure that is termed as Efflux. There are various unique features of this pylon that take its efficiency level to newer heights when compared to the regular wind turbine structures. You would be wondering what is the addition to this pylon that makes it different from other similar structures! Then, check out some of the exclusive characteristics of this power producer.


Solar Vs. Conventional Vs. Diesel Power in India

This graph prepared by Headway Solar (P) Ltd. predicts on basis of our estimate, the future comparison of cost of Solar PV Power Vs. Conventional Power (such as Coal ,Nuclear mix) Vs. Diesel Gen-Set based Power. On the basis of this graph we can predict that Solar Power Boom without any Government Support will begin in and around 2016-2017. After this period the growth in Solar Power for distributed and centralized Power Generation will be immense.



Computer Data Centers Powered by Poop

A series of Google searches can require as much energy as an 11 Watt light bulb does in one hour. So you can only imagine how much energy it requires to run all of Google’s servers and other equipment (hint: a lot). Currently, many companies are attempting to reduce their energy usage through different methods. Google, for example, has developed advanced cooling methods and energy saving techniques to lower their environmental impact.

Other IT companies are quickly following suit. Most interesting is HP, which just yesterday presented a paper to the 4th International Conference on Energy Sustainability entitled “Design of Farm Waste-Driven Supply Side Infrastructure for Data Centers.” The paper describes HP’s plans to hopefully power their data centers with the manure of cows.




Hitting the gym is about to get a whole lot greener as SportsArt Fitness just unveiled an energy-generating exercise machine that produces watts as you work out! The company’s new S770 Pinnacle Trainer features a kinetic energy-generating design that feeds excess electricity back into the power grid. The machine can generate up to 2,000 watts during use, and it can potentially save up to $3,000 in utility bills each year.


The machine utilizes “forward/backward and medial/lateral” motion to improve core stability and balance, and it activates various muscle groups for a complete workout. The new machine also has a monitor for heart rate, and it is completely powered by the kinetic energy generated during a workout – all one needs to do is start exercising.

SportsArt Fitness is marketing their new product as one of the first of its kind. “The power inverter attached to the Green System is about the size of a stereo receiver and operates on 208 – 240 VAC power,” says Bob Baumgartner, Product Manager for SportsArt Fitness. “The product feels and acts like any other cardio product… but what happens behind the scenes is not like any other cardio product.”

This S770 is also a great option for those who prefer to set up their own home gym – it represents a good long-term monetary investment, and it’s a huge step forward for environmental sustainability. Hopefully we’ll see more energy-generating exercise equipment in the future!

Oil well taps wastewater for renewable energy

An oil drill in Mississippi is breaking new ground in waste heat, using unwanted water to run a generator that runs on waste heat.

ElectraTherm, which makes the waste heat generator, said the Denbury oil well near Laurel, Miss., has successfully installed its GreenMachine product and shown that it can provide 20 percent of the electric power needed for the drilling. The demonstration was funded by a $460,000 federal government grant, half of which was paid for by one of ElectraTherm’s distributors.

Waste heat is considered a relatively untapped source of energy that could make many industrial processes, such as power generation or manufacturing, more efficient.

Electratherm’s generator is designed to operate using a relatively low-temperature heat source and produce between 30 kilowatts and 65 kilowatts. At the Mississippi well, drillers seeking new sources of oil generate 4,000 barrels of unwanted water per day. At 204 degrees Farenheit, it can operate ElectraTherms’ GreenMachine.

The generator operates using a similar principle to ground-source heat pumps. The heat from the water, or another heat source, causes a refrigerant fluid in tubes to evaporate. The pressure from that gas turns a mechanism connected to a generator to make electricity. Using fans, the gas is then cooled down back into liquid form to start the process again.

Oil wells have used waste heat to generate electricity before, but the advantage the Green Machine has in the field is that it’s portable, ElectraTherm representative Celeste Dodge said today. After one well has been drilled, it can be moved to another location. The generator in Mississippi was installed in 50 hours.

Waste heat is a free source of energy, but waste heat generators compete with grid electricity prices. In places where electricity costs 10 cents or higher per kilowatt-hour, the return on investment for a GreenMachine is four to six years, according to the company. The national average is 11 cents per kilowatt-hour. In places with cheaper electricity, such as the U.S. Southeast, there isn’t a big incentive to invest in waste heat generators without grants or policies to promote renewable energy, she said.
