Today, most of the liquid biofuels are sugar or starch based and are obtained from crops of sugar beet, sugar cane, potatoes or corn. A problem in the future could be the lack of lands. These crops use good lands on which food can grow instead. An idea to decrease use of proper agricultural lands would be to use the unproductive lands to obtain biofuels.
There's nothing new when we hear that Toyota launches a new hybrid. But now it's a little different, as we are talking about the first luxury hybrid in the world, created by Lexus this time (Toyota's luxury trademark).
Recently, German scientists have broken a new record in solar cell efficiency: 41.1%. It seems like the scientific world is in a continuous race towards more and more efficient harvesting of solar energy, but few use it at its maximum power.
The company that produces the energy in Ontario, OPG - Ontario Power Generation started the process of finding providers for biomass fuel, by sending a "call for expression of interest" to those interested to change the coal to biogas for producing the electricity in the region.
The company is looking forward to create the list with...
The first electric car that will go into mass-production is going to be sold later this year in UK by Mitsubishi. i-MiEV, based on the Mitsubishi's i model, is larger than a Smart for Two but with similar design and has room for four adults.
A long time ago, President Obama announced his agenda as very different from what we are used to. He lets us see that US economy can not only not lose, but also win from keeping environmental policies at the front.
Genetic engineering allowed human kind to evolve and differentiate certain species of food, make them better or more productive. Likewise, genetic engineering is blamed to have ruined the natural evolution path of the affected plants or animals. Now, genetic engineering is being used to extract energy for us, in the form of hydrogen.
The fact that hydrogen fuel cells are powered by gas coming from fossil fuel made Japanese scientists invent other alternative sources of hydrogen like dough and sewage.
Biodiesel has recently become a very controversed biofuel. It can be obtained from vegetable oil, animal fats, used cooking oil, microalgae and is a potential replacement of petroleum-based diesel fuel. By doing some research, NIST scientists found out some additives that make biofuels act better at high temperatures.
The use of wind power has been around for centuries, from the simple sail to the sophisticated windmills. The inconvenience of harvesting wind energy is that most of wind-farm sites are placed far away from the areas that need the power.
