As the PV business continues to grow, new backsheet constructions are continually being introduced. But the products we use in our efforts to be more sustainable have a bigger footprint than we think. Currently, there are at least ten commercial manufacturers of traditional PV backsheets, with traditional products in the development stage. Traditional backsheets, the protective covering on solar cells, are produced mainly from polyester and Tedlar films. Polyester is made from petroleum and Tedlar is solvent-cast using DMAC, a highly toxic industrial solvent. Both of these products defeat the purpose of clean, green energy, and as the demand for solar energy increases, so does this issue.
While the United States is rich in renewable resources for the production of green electricity, expansion and modernization of the North American power grid will be required to transmit that power to where it is needed.
Remember the First law of thermodynamics? Energy can neither be created nor destroyed. It can only change forms. Or, if translated into an idiot-proof rule of thumb: you can't go above 100%. Remember this? Now forget it; this law has got a loophole.
One of the most serious gases we must use is Hydrogen - in our cars, buses, Space shots from the cape etc. I have been studying Hydrogen, Propane and many Bio-fuels and have found hydrogen to be the best, the oldest and the cleanest. I feel this alternative product is a win -win.
The eco-sheet shows that there is no silver bullet solution. When looking at CO2 emissions only, it would be clear what options to take. However, this is not the only environmental consideration. Not preferring any particular method of electricity generation, the eco-sheet lists the main environmental impact categories and benchmarks them against the electricity generation mixes for the EU 25 and EU 15.
Ultimately, battery-free operation is a key step in paving the way for truly green systems that do not adversely impact the environment. This environmentally-friendly approach can also extend the reach of sensing technology to distant and inhospitable climates and regions.
HPCC's energy efficient applications, such as networking thermostats in homes and demand control, remote management of high power appliances, etc. ensure a more environmentally friendly future.
The marine energy industry has a long way to go but ongoing research and government support should lead to improvements making these technologies more economically attractive in the future. Combined with intensifying company activity in this field, Europe is poised to be the place to watch in the marine energy arena of the future.
European waste management market is continuing to restructure and reform. The ongoing move away from landfill is continuing to attract technological innovation and the current leaning towards waste to energy in many parts of Europe is attracting major capital investment with improving opportunities for returns.
With the fossil fuel prices increasing rapidly, the waste from scrap tires will certainly be increasingly be made use of. Developing innovative and economical as well as effective systems for TDF usage is and will always be a challenge to the business.
Until now, acoustic or sound energy has not been used effectively to impose thrust or force on an object for purposes of providing useful work.
The new century oil and coal companies will "Grow" their carbon fuels in bioreactors using safe and cost-effective biotechnology.
Bio-Lipid oil can also be used to produce one of the lowest cost and most environmentally friendly fuels known to man: bio-diesel. Bio-diesel made from bio-lipid oil, from micro-algae, burns cleaner, produces less CO2 (with no sulfur dioxide emissions) than petroleum based diesel fuels, and it's renewable and sustainable.
With all of us now keen on doing our best to find out those alternative energy avenues that will make or break civilization fifty years from now, it is imperative that individuals and professionals try to convince their governments, corporations & scientific research institutions of the need to put in more research into exploring algae as a feedstock for oil.
Gas hydrates are the potential source for alternative fuel for world. To explore the gas hydrate as reliable source of alternate energy extensive research and developments are required.

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
