Recently a company based in Tel Aviv, presented their latest invention – a specialized colored panel, resembling a colored plexiglass which is able to produce power from diffused light using a solar cell.

According to GreenSun Energy, their latest invention is glass made with fluorescent dyes and nanoparticle metals. Besides being more efficient, the new solar cells could also have a lower cost compared to traditional solar cells. Another advantage of the new solar cells is that they require approximately 80% less silicon than the traditional ones (less silicon means a lower cost of production). When sunlight (be it direct or indirect) touches the panels, it disperses across and the metal nanoparticles bring the sunlight to the sphere where the silicon is placed.

This latest invention costs 2.05$/W and is 13% more efficient than traditional solar panel, which costs around approximately 4.54$/W. In addition, CleanTechnica informs that the conventional solar panels have efficiency loss because of the heat does not turn into energy. In the new solar panels, the sunlight is diffused across the entire panel, thus nanoparticles are able to bring light to the edges of the panel where the light is transforms into energy.

Scientists at GreenSun look forward towards increasing the efficiency of their new solar cell from 13% to 20%. They also hope to reduce the costs of producing the new panels to approximately 1$/W.

“Litroenergy” was also submitted to the “NASA” Create the Future Design Contest to compete based on its originality and potentially major impact on sustainable energy technology.

Wind Energy is Renewable energy harnesses natural wind power – Effective answer for global ecological problem towards cleaner and greener environment:

The simplest wind-energy turbine consists of three crucial parts:

1.Rotor blades – The blades are basically the sails of the system; in their simplest form, they act as barriers to the wind (more modern blade designs go beyond the barrier method). When the wind forces the blades to move, it has transferred some of its energy to the rotor.

2.Shaft – The wind-turbine shaft is connected to the center of the rotor. When the rotor spins, the shaft spins as well. In this way, the rotor transfers its mechanical, rotational energy to the shaft, which enters an electrical generator on the other end.

3.Generator – At its most basic, a generator is a pretty simple device. It uses the properties of electromagnetic induction to produce electrical voltage – a difference in electrical charge. Voltage is essentially electrical pressure – it is the force that moves electricity, or electrical current, from one point to another. A simple generator consists of magnets and a conductor. The conductor is typically a coiled wire. Inside the generator, the shaft connects to an assembly of permanent magnets that surrounds the coil of wire. In electromagnetic induction, if you have a conductor surrounded by magnets, and one of those parts is rotating relative to the other, it induces voltage in the conductor. When the rotor spins the shaft, the shaft spins the assembly of magnets, generating voltage in the coil of wire. That voltage drives electrical current (typically alternating current, or AC power) out through power lines for distribution.

Harnessing renewable energy is the perfect way to tackle the ecological crisis of the world. Renewable energy is energy which is made from resources that Mother Nature replaces. Renewable energy is also called “clean energy” or “green power” because it doesn’t pollute ours Nature. Wind energy is one such renewable energy source that harnesses natural wind power. People try to make many assumptions against wind turbines for generation of wind energy; but the fact remains, wind energy is most suitable form of renewable energy we can have to replace coal fired / nuclear powered / and even oil fired power plants in the near future. In support various points are discussed below:

Wind power is clean because it is generated by blowing air. Wind energy transform in kinetic energy and use as mechanical energy or electricity. The amount of energy produce depends mainly on blowing wind speed; density of air affects the energy produce by wind, which is determined by the humidity, barometric pressure, dryness.In the case of a wind-electric turbine, the turbine blades are designed to capture the kinetic energy in wind. When the turbine blades capture wind energy and start moving, they spin a shaft that leads from the hub of the rotor to a generator. The generator turns that rotational energy into electricity. At its essence, generating electricity from the wind is all about transferring energy from one medium to another.

Energy of wind power depends upon speed of air when increase in speed of air then increase in generation of energy and when decrease then decrease in energy generation. So locate the wind power plant in windiest areas. A modern wind turbine is designed to operate for more than 20 years and at the end of its working life, the area can be restored at low financial and environmental costs. Wind energy is a form of development which is essentially reversible – in contrast to fossil fuel or nuclear power stations. A modern wind turbine produces electricity 70-85% of the time, but it generates different outputs depending on the wind speed. Over the course of a year, it will typically generate about 30% of the theoretical maximum output. This is known as its load factor. The load factor of conventional power stations is on average 50%. A modern wind turbine will generate enough to meet the electricity demands of more than a thousand homes over the course of a year.

Cost of wind energy is determined by initial cost of the wind power plant – any wind power plant that is installed in a windy area generates less expensive electricity than the same unit installed in a less windy area.

The average wind farm will pay back the energy used in its manufacture within 3-5 months of operation. This compares favorably with coal or nuclear power stations, which take about six months. All forms of power generation require back up and no energy technology can be relied upon 100%. Variations in the output from wind farms are barely noticeable over and above the normal fluctuation in supply and demand.The cost of generating electricity from wind has fallen dramatically over the past few years. Between 1990 and 2007, world wind energy capacity doubled every three years and with every doubling prices fell by 15%. Wind energy is competitive with new coal and new nuclear capacity, even before any environmental costs of fossil fuel and nuclear generation are taken into account. As gas prices increase and wind power costs fall – both of which are very likely – wind becomes even more competitive, so much so that some time after 2010 wind should challenge gas as the lowest cost power source. Furthermore, the wind is a free and widely available fuel source; therefore once the wind farm is in place, there is no fuel requirement or no waste related costs.

Fact: Wind energy is a benign technology with no associated emissions, harmful pollutants or waste products. In over 25 years and with more than 75,000 machines installed around the world, and there is no report of any body has ever been harmed by the normal operation of wind turbines.

Wind Power

Wind can generate electricity for homeowners. Wind is created by unequal heating of the earth”s surface and can be used to directly produce electricity. A wind turbine captures the energy of the wind and converts it into rotary motion that drives a generator to produce electricity.

Much like home PV solar systems, small wind systems can be eitheroff the grid or grid connected. With grid connected wind systems, the homeowner can sell excess electricity to the utility or purchase electricity from the utility if necessary during low wind or no wind conditions.

The ability to use wind systems to produce electricity is more limited than opportunities of solar systems. While solar systems can be used in many U.S. locations, careful study is required to ensure there is adequate wind to allow wind systems to function efficiently. Zoning requirements in residential areas may also limit use of wind power systems.

Hybrid of Wind & Solar Systems

There are advantages to considering an on-site electric system that rally wind and solar. This hybrid approach is common for homes that are in steading. By mixing wind and solar, the weakness of each approach (lack of wind or sunlight) can be offset. In the United States, wind speeds are often lowest in the summer when the solar energy from the sun is strongest, while wind tends to be stronger in the winter when less sunlight is available. A wind/solar hybrid system offers a more reliable approach to year-round electricity production than either approach alone. Typically, these off-the-grid hybrid systems utilize a battery system to store electricity when household energy demands are low and to supplement the system”s output when household needs exceed the electricity being produced. It is a stave off brown outs.

The solar power plant generates approximately 10MW of power, enough to buffer it from fluctuations in the grid which result in frequent brown outs, from state power provider. More importantly for the company, they are able to achieve savings of up to 80% in good weather & 50% in cloudy times, considering that electricity doubled in price last year, significant savings indeed. It”s Ecological, Economical, Effectively working power system on your property.

Panasonic, the giant Japanese based electronics manufacturer and marketer has launched an LED lightbulb, for the US market at the Consumer Electronics Show (CES) in Las Vegas. The bulb, which was first launched in Japan in september, is known as the EverLed, requires no change of lighting equipment, fitting in standard screw in fixtures for incandescent light build.

Led technologies

Consumers will be able to swap out a 60watt traditional bulb with a 6.9 watt “bulb” with several LEDs. Panasonic has branded the bulb, which are expected to last 19 years, as the “EverLed” and they currently sell for approximately $40 USD. The bulb can be expected to save 8200 kwh or about over $500 of electricity at 7 cents per/kwh.

Enough solar energy falls on the earth”s surface in twenty minutes to meet our needs for a year. Exploiting this resource is essential in light of our growing energy use and continued battle against man-made global warming.

We can harness the sun”s energy directly for domestic space and water heating, or a proportion of its energy can be converted into electricity using photovoltaic technology.

Solar power

Europe has invested heavily in solar power in the past decade. The data below shows that over the period 1996-2007, the amount of energy generated using the sun”s rays has quadrupled within the European Union.

Although not in the EU, Turkey has always been a believer in the power of the sun. It topped the table in 1996, generating nearly twice as much energy as its nearest rival, Greece. The majority of the energy exploited in Turkey was used for domestic hot water.

Recognising the need to secure future energy supplies, Germany has picked up the baton as the solar energy leaders of not only Europe, but the world. Heavy investment in manufacturing and a scheme paying solar panel owners a premium for their electricity has seen its solar energy generation increase by over 800% in 11 years.

President Obama announced the awardees of the program, worth $2.3 billion in tax credits. The White House says “the tax credit program will help build a robust high technology, U.S. manufacturing capacity to supply clean energy projects with U.S. made parts and equipment. These manufacturing facilities should also support significant growth in U.S. exports of U.S. manufactured clean energy products.”

Renewable Energy Wind

Commercial viability, domestic job creation, technological innovation, speed to project completion, and potential for reducing air pollution and greenhouse gas emissions are some of the criteria used to assess how the tax credits are allocated. The White House says the program was oversubscribed by a ratio of more than 3 to 1, “reflecting a deep pipeline of high quality clean energy manufacturing opportunities in the U.S.”
