Nano-spike catalysts convert carbon dioxide directly into ethanol

In a new twist to waste-to-fuel technology, scientists at the Department of Energy’s Oak Ridge National Laboratory have developed an electrochemical process that uses tiny spikes of carbon and copper to turn carbon dioxide, a greenhouse gas, into ethanol. Their finding, which involves nanofabrication and catalysis science, was serendipitous. Learn more:

If we reduce our use of fossil fuels, we will reduce the amount of extra carbon dioxide that we put into the atmosphere.

There are 2 ways to reduce our carbon dioxide emissions from burning fossil fuels:
1) We make our processes more efficient
2) We replace the use of fossil fuels with other fuel supplies

Examples of improving efficiency is replacing filament lightbulbs with lower energy options such as LED lights, improving the efficiency of car by increasing the number of kilometres driven per litre of fuel, insulating houses better are just a few examples.

Replacing the use of fossil fuels would be a better solution. Some options for this is to use hydroelectricity, solar power, wind turbines, tidal power, wave power, nuclear energy and natural gas.
