Printable cells, the revolution of clean energy

Scientists came up with this good idea and are working very hard to get the so-called printable solar cells. It has been difficult and many challenges must come, but as Professor Ted Sargent said ““Economies of scale have greatly reduced the cost of silicon manufacturing””. I also think that this type of sustainable ideas are… Continue reading Printable cells, the revolution of clean energy

Could sand grains be used to produce energy?

Some scientists from the Monash University discovered a potential way of producing renewable fuel from sand. It may sound crazy, but the explanation lay on the fact that some micro algae called diatoms live among the sand grains. These creatures take sun light and transform it through metabolism to produce hydrogen gas. Scientist hope that… Continue reading Could sand grains be used to produce energy?

Mimic-nature device that produces energy

Some scientist from the Iowa State University designed and built a small device that could generate energy thanks to a piezoelectrical processes. They chose to use and model the Cottonwood leaves because its flattened leaves oscillate in a regular pattern that optimizes energy generation due to shape and physiognomy of its leaf stalks. It is… Continue reading Mimic-nature device that produces energy

Can solar power storage increase energy consumption?

Actually yes. According to a study done by some scientists of the Cockrell School of Engineering at The University of Texas at Austin, storing solar energy for nighttime increases the annual energy consumption by about 324 to 591 kilowatt-hours per every house. This is not the end of solar energy though, but it is a… Continue reading Can solar power storage increase energy consumption?

An outstanding example from Nordic countries about energy transition

Nordic countries are well known for being wealthy, small and well developed. These countries have been working on developing new technologies and strategies for the shifting of regular energy production towards a more sustainable and more energy efficient system. According to the Centre on Innovation and Energy Demand about 83% of electricity generation in Nordic countries… Continue reading An outstanding example from Nordic countries about energy transition

Scotland in the way of sustainability

Scotland is giving us an example of what should be done in all latitudes in order to decrease the damages done to the environment by the activities of the increasing population. Their targets are to increase the use of ultra-low-carbon cars, green electricity and green home heating by 2032.  Let’s see if they can achieve their… Continue reading Scotland in the way of sustainability
