Hamburg is one of the most important cities of Germany and has a huge population that depends on public transportation. On that note, the first ten Mercedes-Benz Citaro FuelCELL-Hybrid buses were launched on the streets. The fuel cell hybrid cell is virtually non-polluting and would keep this amazingly chic German city non polluted and clan. [...]

Cleantech depends on energy policy. US President Obama deals with two core climate issues: meeting the larger goal of reducing carbon emissions, and finding a way of rescuing the renewables industry from Wall Street’s collapse. The benchmark of 450 ppm is a crucial figure issued by the Intergovernmental Panel on Climate Change. ‘Limiting concentration to [...]

The current mantra is to ‘reduce greenhouse gas emissions more than 25 percent by 2020 — and more than 80 percent by 2050.’ While these attempts will curb our dependence on fossil fuels, doing ‘everything possible to promote alternative energy’ may also entail ‘financial, political, and technical pressures as well as time constraints that will [...]

John A. Rogers who is an eminent professor of materials science and engineering at the University of Illinois has devised a way to trap the solar energy in better ways. Until now, one could only harness solar energy through solid and fixed panels that absorbed solar energy, which would later be converted to other forms [...]

Wind energy can be a rich source of alternative energy provided you have the right climate for it. Additionally, it is important to see that the energy can be harness appropriately and in good time. Unfortunately, often enough, the presence of one thing leads to the absence of another.
In the United States, the Midwest provides [...]
