To use it further, a research team at the Harvard School of Engineering and Applied Sciences are conducting research to utilize methane on a laptop fuel cell and battery.

A team led by Shriram Ramanathan has focused on solid oxide fuel cell types (SOFC) that rely on methane produced from biogas and certainly does not use platinum anymore.

In addition, they also developed a micro-scale SOFC working at a temperature of 500 degrees Celsius. According to Ramanathan, if SOFC can operate at temperatures 300-500 ° C temperature range, it will open more implementations, such as in vehicles and portable electronic devices. In fact, still thinks, that they develop SOFC will no longer depend on pure hydrogen as fuel, but a variety of other fuels, as well as replace batteries for laptops and other portable electronic devices.

Jochen Flasbarth, president of the Federal Environment Agency – a German government agency which deals with environmental issues – German [...]]]> Germany, the country that leading adopters of solar cell technology to generate electricity GigaWatt 14 at the end of 2010, set a target to produce the overall supply of electricity from renewable energy sources in 2050.

Jochen Flasbarth, president of the Federal Environment Agency – a German government agency which deals with environmental issues – German target is not a dream in the daytime, because of technical and ecological point of view this target it is possible to achieve.

From the technical side, recently Germany has reached 16% of electricity from potential wind, solar and other renewable energy sources. This figure tripled from the previous fifteen years. Solar energy itself is almost reached 14 GW in this year and become the second country after the United States in the production of electricity from wind energy.

While the environmental side, from 1990 until 2020, Germany succeeded in reducing greenhouse gas emissions to 40%.

A study carried out by the agency also confirmed that the switch to electricity sourced from renewable by 2050 will provide an economic advantage, especially for export-oriented manufacturing industries. Besides tens of thousands of new jobs will be created simultaneously with the development of technologies and renewable energy industries.

The magnitude of the cost required to replace the entire supply of electricity from renewable energy sources is much smaller when compared with the costs of future generations of Germany if the problem of climate change is a major problem of the country.

Human generations has been farming for their daily meals. [...]]]> The use of biodiesel is being campaign by the government which is expected with this solution is the use of diesel fuel can be reduced because of the mix with diesel, which is the result of the oil palm oil, corn, soybeans, space, sugar cane, cassava, etc..

Human generations has been farming for their daily meals. Even today we still see a lack of food from some country. We still can not self-sufficient in food. With the growth of both sides of the human population and the car, if we will use some food items that need to be energy, whether we want to feed people or cars?

There will be no land, water or soil productive enough to be able to replace all our energy needs. Production of biodiesel itself also uses a lot of land and energy. Production of land plants such as palm oil or distance will require fertilizer made from natural gas results, the pesticide is also derived from oil, the input of energy such as fuel for tractors, trucks, and distillation plant. In addition, the land will also need to reduce water and soil fertility power.

When we see the energy used, the biodiesel will use more energy in the production stage compared with ordinary oil, from exploration wells to be used in the car.

With the competition between the need for human food and energy, so the supply is running low demand and high commodity prices will increase so that by the end of the chain then the final product sold to customers would be more expensive. For example, when palm oil prices rise, because oil palm is the basic ingredient for the manufacture of ice cream, biscuits, butter, cooking oil to soap and shampoo, it is conceivable consequences of CPO prices rose to around inflation and our economy.

Employers also with the price increase would be their incentive to plant more. And if our heterogeneous forest full of useful plants and animals that depend on these ecosystems, would be destroyed by the homogeneous forest of large plantations. Finally is the destruction of plant and animal species that important to our natural balance.

The best solution remains to find the best solution alternative renewable energy from water / wave, wind and sunlight.
