We are using fossil fuels as the primary source of energy to run our Industrial Civilization. But we are paying a heavy price for using fossil fuels in the form of environmental damages. Now, we know that fossil fuels and natural gases are not going to last forever. This will lead us into big problems. [...]

With its windy coasts, untapped rivers and huge tidal and wave resources, Alaska can quickly become a national leader in producing alternative energy. Although Alaska is the second-largest oil producing state in the country, the citizens have had to pay very high electricity bills recently; oil is no longer easily available for producing and generating [...]

We all know that the need of the hour is alternative energy so that future generations can still breathe fresh air and have enough energy for their industrial purposes and domestic use. Many states and countries are promoting wind energy as a clean and green energy. We all know the advantages and disadvantages of alternative [...]

How about a vehicle that not only draws energy from an electric grid but also gives it back when there is surplus or unused energy in the vehicle? This is exactly the kind of car being developed by Willett Kempton, a renewable-energy professor at the University of Delaware. Now, you may wonder what sort of [...]

Tomorrow our vehicles may derive power by enzymes. These enzymes may originate from the cellulose of woodchips or grass and instead of emitting poisonous gases they will exhale hydrogen. We know that when hydrogen is burned, the only emission it makes is water vapor, so a key benefit of hydrogen fuel is that when burned, [...]

We mostly talk about solar panels that convert sunlight into electricity. But we can utilize sunlight by using another technology known as concentrating solar technology. In this technology reflective mirrors are used to concentrate light onto a liquid to make steam. This steam then converts energy into electricity with the help of conventional turbines. Deserts [...]

Solar cells are usually made of silicon coated with a thin layer of silicon nitrate. This silicon nitrate works as an anti-reflective agent to boost cell efficiency. But the catch is these types of cells are costly to produce. This anti-reflective layer deposition happens in vacuum and creating vacuum like situation doesn’t come cheap! Efforts [...]

Jets, concords and Boeings make our lives and traveling easier and faster. Rising prices are forcing companies and institutions to look for alternative fuels. NASA and 11 other research groups are testing two non-petroleum-based jet fuels that will be viable for commercial jets too and aviation companies can heave a sigh of relief as far [...]

People who want to use clean and green energy often complain about high costs of solar panels and even a longer breakeven period. So research teams and companies are constantly trying to improve upon the drawbacks of solar panels. Suntrof Systems LLC is bringing forth a new innovation in solar collector panels that could bring [...]
