Nano-Spike catalysis; discovery of the Oak Ridge National Laboratory made a little ... by chance! The process makes it possible to obtain ethanol from CO2, electricity and water in the presence of a specific nano-catalyst called Nano-Spike. The reported return on electricity is 60 to 70% which is acceptable provided renewable electricity is used (the process [...]

The Mitsubishi MiEV is an 100% electric car that would therefore indirectly, taking into account only the manufacture of [...]
Geothermal energy, heat pumps, energy savings and CO2 emissions
To ourt, geothermal energy is all too often presented as a renewable and "green" energy.
This article concerns the surface geothermal energy, called heat pumps, not deep geothermal or deep heating networks catchments themselves are completely renewable.
So if the energy [...]
