Not a few people who think that technology is only as environmentally unsound. However, such an assumption is apparently opposed by many scientists that develop environmentally friendly technology. The UN estimates that world energy demand will rise by 60 percent in 2030. It is not perhaps as much as 2.9 billion people will lack a supply of clean groundwater.
Human exploitation on a large scale the earth's natural resources can be spent very natural supply. It is not impossible that one day the earth's natural resources will be completely depleted if not wise in their usage in the present.
Here's a list of environmentally friendly technologies that could save the future of the earth. Our mother earth's fate is in our hands.
The UN noted, the water supply will be very limited for the billions of people in the middle of this century. There is a technology called desalination, which removes salt and minerals from sea water so drinkable. This is a solution that can be done to avert the water crisis.
The problem is, the technology is still too expensive and requires considerable energy. Now scientists are looking for a way for desalination can take place with less energy. One way is by evaporation on the water before it goes into membranes with microscopic pores
There is a process called thermo-depolymerization, a process similar to how nature produces oil. For example, if carbon-based waste is heated and pressurized precise, capable of producing oil material. Naturally this process menbutuhkan millions of years. Of the experiment they had done before, turkey dung can produce about 600 pounds of petroleum.
3. Hydrogen Fuel
Hydrogen fuel is considered as a non-polluting alternative fuels. Energy generated from the combination of hydrogen and oxygen. The problem is how the hydrogen is produced. Molecules such as water and alcohol must be processed first to extract hydrogen that become fuel cells. This process also requires energy. But at least scientists have tried to make laptops and other devices to power a fuel cell.
4. Sun Energy
Solar energy reaches the earth is made up of photons, can be converted into electricity or heat. Some companies and housing has been successfully using this application. They use solar cells and other solar thermal energy collector as a medium.
5.Konversi Heat Sea Water
Media largest solar collector on Earth is sea water. U.S. Department of Energy (U.S.) calls, ocean to absorb solar heat energy produced is equivalent to 250 billion barrels per day Minyal. There is a technology called OTEC is capable of converting ocean thermal energy into electricity. The temperature difference between the sea surface and was able to run turbines drive the generator. The problem is, the technology is still less efficient.
6. Sea Wave Energy
Ocean covers 70 percent of the earth's surface. Huge wave of energy saving that can drive turbines that power mengasilkan. The problem is rather difficult to estimate when the ocean waves large enough to produce enough energy.
The solution is to store some of the energy when the wave is big enough. East River of New York is currently a pilot project with six turbine-powered water gelombanng. While the Portuguese actually already been practicing these technologies and successful light more than 1,500 homes.
7. Roof Plantation
The concept is inspired by the Hanging Gardens of Babylon in the list of the Seven Wonders of the World. Babylonian palace consists of a roof planted with a variety of flora, as well as a balcony and terrace. The roof garden is able to absorb heat and reduce carbon dioxide. Imagine if birds and butterflies fluttering around our green house.
There is a process called bioremediation, the use of microbes and plants to clean up contamination. One is cleaning the nitrate content in the water with the help of microbes.
Or use the plants to neutralize arsenic from the soil. Some native plants have turned out to cleanse the earth avail us of various pollutants.
