Personally, I like my lithium battery powered hand tools, BUT I also know that they are not as powerful as my old fossil fuel powered tools. Just a few observations. I have not been convinced that man is powerful enough or god like that we can change the climate. If so, can someone raise the temps during the winter up in the mountains up North so that I can enjoy a warmer mountain climate? I prefer the mountains over the flat Florida landscape, but it gets way too chilly up North in the mountains.

Actually, I have studied electrical principles somewhat. Batteries produce direct current (DC) and everyone's home electricity is alternating current (AC at 120 volts). When it comes to motors inside common hand tools like drills - the DC motor is normally considered more "powerful" because the INITIAL TORQUE of a DC motor is superior to an AC motor. Even when you compare a large automobile engine like DC versus an internal combustion engine - the DC motor wins the 0 to 60 mph time trials because of the fact that DC motors have the greatest INITIAL TORQUE.
Originally Tomas Edison planned to electrify cities with DC power. But, AC won that battle because with very efficient transformers and voltage changes AC can be transferred greater distances than DC.
As to the question of "How are electric cars going to STOP the climate from changing? That requires a longer answer which could be pieced together by the posts made by myself and others. Here is the quick and dirty version...........
........When trees and plants are cut down for concrete and golf courses and the earth's ocean becomes polluted with plastic and excess CO2, the water becomes slightly acidic and bleaches and kills the new growth of coral on the reefs. Algae can also attack the coral (which was talked about in a previous post). Without coral, the fish die. And the ocean dies, in that, it can no longer act as a container or buffer to hold CO2.
Then excess CO2 ends up in the upper atmosphere and acts like an insulating blanket to the earth, which becomes hotter as a result.
The internal combustion engine (ICE) some call it infernal combustion........produces a large part of the CO2 total from burning fossil fuel. Power plants generating electricity also burn fossil fuel, but since they are at a SINGLE location (as opposed to a moving automobile) the power plants can have more potent and large-scale CO2 scrubbers. When power plants can economically burn NATURAL GAS the pollutants cast off are minimal. Note : large scale forest fires like recently out west MUST also produce CO2.
Summary........the increasing popularity and worldwide use of electric vehicles (EV) will NOT stop Climate Change instantaneously, but are a long-term solution to the problem. And they are a solution that is available and affordable to each citizen in the 1st world. Over time, they will become more affordable and more attractive to the average citizen. As such, they become a GIFT to succeeding generations !
