Canadian scientists, according to the United Nations (UN) global climate change objectives to reduce carbon emissions and reduce sicakliklik in the context of global increase of fossil fueled vehicles with electric cars by 2050, 90 percent of needs to be replaced.
Researchers from the University of Toronto, based in Canada, created a computer model to predict how many electric vehicles will be needed in 2050 in a country that is overly dependent on cars.
The team focused the study on the United States, which is a wealthy country with a high rate of total vehicle ownership per capita. In the US, only 0.3 of the total vehicles are currently powered by electricity.
“NOT A REALISTIC GOAL”
To meet U. N. climate targets, about 90 percent of passenger cars in the U.S. need to be electric by 2050. But the researchers suggested that this was not a realistic goal and that countries should invest heavily in public transport, rather than electric cars, and focus on redesigning cities to allow more rides by bike or on foot.
UN climate targets require member states to take action to prevent global temperatures rising 1 degree above pre-industrial levels by 2100.
However, researchers said that more than seven million electric vehicles are currently used worldwide, compared to 20 thousand vehicles a decade ago. However, scientists noted that while this is a huge change, it alone is not “effective enough to address the global climate crisis.”
350 MILLION ELECTRIC VEHICLES NEEDED TO HIT THE ROAD IN U.S.
According to the study, published in the journal Nature Climate Change, about 350 million electric vehicles need to be used in the United States by 2050 to combat climate change.
‘It’s true that sales are growing rapidly, but even the most optimistic forecasts suggest that by 2050 only 50 percent of the U.S. fleet will be in electric vehicles,’ said study author Alexandre Milovanoff.
CALLS FOR NEW POWER PLANTS TO BE BUILT
On the other hand, the researchers said that although electric vehicles reduce emissions, they will create a higher demand for electricity, and because of this, new power plants will need to be installed. According to the study, a fleet of 350 million electric cars would increase annual electricity demand by 1,730 TWh, about 41 percent of current levels.
