The president of the OPEC stated earlier this week that oil prices might keep on climbing steadily and reach 200 USD per barrel before year end. This might seem far-fetched, but since the beginning of the year, oil prices rose by nearly 20 percent and there is no sign that the situation will reverse.

But the more I am thinking about it, the more I believe it actually can be done if… Continue reading Why dividing by four our CO2 emissions can be done
I knew that Germany had plans to build coal fired plants. Little did I know that according to this great article from the IHT other European countries like Italy are willing to do so.

But a team of researchers… Continue reading Aerogel, the future of insulating materials
