Take the battery pack for instance, apprently it is said that the amount of energy spent to create a battery of such capacity (which again the source is mostly fossil fuels) is far more than what the derived benefits of using it battery itself. To me unless we find a radical easy and cheap method of finding energy (electricity) say from Hydrogen (Read water) happens, whatever we end up doing to "appear" environment friendly might not result in the desired result.
If I did live up my claim of ignorance, please correct me wherever i am wrong. |
Agree that the electricity produced is also from Thermal power stations, a lot of it in our country. Now, my answer to how green really are hybrids or electric cars are will be from Elon Musk's answer which is:
Even in the worst case scenario where electricity from the grid is from a coal powered plant, the electric cars' impact on the environment will still be lesser than of that of a petrol/diesel powered car.
Yes, the source of electricity does matter. But even if that is coal, when the electric car does run, it does not emit green house gases. So its more about greener tech than green tech.
I guess the bottom line is how you can minimize your carbon footprint and not about brining it to zero.
Example: We are installing a 2KW solar panel set up at home with a hybrid inverter. The order/priority of power source will be Solar, battery and lastly grid.
So it essentially means that we can be "off-grid" for about 12 hours a day or more, if battery is also used. Yes, it does cost 2.5 Lakh rupees, but the gains or ROI, I feel are long term. Trying to be greener.
Pardon me if that OT. |
