Fossil fuel is a common word used to refer to buried flammable geologic deposits of organic substances. They are created by decomposed plants and animals which were altered to natural gas, heavy oils or crude oil due to being exposed to a lot of heat and
There is a snag, however. Industrialisation is even harder to induce than it was 40 or 50 years ago. Technological advances mean that fewer workers than ever are needed to produce, say, a pair of socks. In India five times fewer workers were required to operate a factory in 2007 than in...
Geothermal energy is energy from within the earth. The earth from inside is too hot. This heat from within the earth can be used to turn turbines and produce electricity. This technology is still a subject matter of further research and engineering. Geothermal Energy How to Generate Electricity ...

The measures Invista has taken to produce COOLMAX EcoMade fibers somewhat mitigate the environmental impact of this polyester fiber, but the remaining four products within the COOLMAX line have a decidedly negative impact on the environment. The production of COOLMAX fibers involves formaldehyde, which...
Any fossil fuel energy, after industrial utilisation such as combustion and electric generation, is finally emitted in the form of waste heat to the atmosphere. A database on waste heat revealed that a large amount of energy can be saved by reusing the high-temperature industrial waste heat eff...

The majority of green hydrogen fuel production projects are focused on PEM electrolyzers of various sizes and designs. How is H2 gas stored and distributed? Once electricity has been used to produce hydrogen fuel, the gas must then be stored so that it can be used when needed. It can be ...
