Kind of obvious but EVs fuelled by coal-powered electricity are worse than ICE, but EVs powered by solar or wind are much better.
Electric cars a mixed bag for health, climate : Renew Economy
It's a hack piece.
The ICE in question is a hybrid.
Which ICEv did they use? I can't seem to find it.
That is not the case with the hydro-electric facilities at Niagara Falls. The plants their store more water in reservoirs at night to store potential energy to be used during the day when demand is higher:Even with hydro a similar thing occurs, a constant flow of water exits the dam while paddles divert more or less through the turbine. using more electricity at night simply reduces the pollution/waste per kW of the system.
At night, a substantial fraction (600,000 US gallons (2,300 m[SUP]3[/SUP]) per second) of the water in the Niagara River is diverted to the forebay by two 700-foot (210 m) tunnels. Electricity generated in the Moses plant is used to power the pumps to push water into the upper reservoir behind the Lewiston Dam. The water is pumped at night because the demand for electricity is much lower than during the day. In addition to the lower demand for electricity at night, less water can be diverted from the river during the day because of the desire to preserve the appearance of the falls. During the following day, when electrical demand is high, water is released from the upper reservoir through the pump-generators in the Lewiston Dam. The water then flows into the forebay, where it falls through the turbines of the Moses plant. Some would say that the water is "used twice". This arrangement is a variant of what is called pumped-storage hydroelectricity. Engineers copied what had been built by Ontario Hydro, across the river, when a similar system was built during construction of the Sir Adam Beck generating station II in the 1950s.
Quite a few places do this, but it would be better to use the electricity to power EVs.Actually the San Louis reservoir in CA pumps water from an after bay back into the main reservoir at night in order to reclaim some excess energy production at night.
