Clean Development

The Millenium Development Goals, agreed to by every member country of the United Nations in 2000, call for the worldwide eradication of poverty and hunger, universal education, gender equality and huge improvements in health by 2015: two years ago!!

Can we do this without making the planet warmer?

Let's think big and imagine how we can confront the climate crisis in a way that is realistic about the other major problems that we face as a planet and as a species on it.

Electric Vehicles vs Gasoline Vehicles - Which is more friendly?

ndkn on MC

I, personally don’t own an Electric Vehicle, but I understand people’s reasoning of owning an electric vehicle. I competed in a competition in which the main goal was to explain the differences between electric vehicles and and gasoline vehicles. I believe that Electric Vehicles are superior in terms of them not emitting as much co2, but they still emit some co2. Opinions below?

I agree, electric powered vehicles don't need motor oil changes and while that still emits some CO2, it is much lower than the emissions from a gas powered vehicle. Because they have not tailpipe, pure electric cars can produce little to no carbon dioxide while driving. Although the production of an electric car tends to be have a higher emission than that of a conventional car, in the long run the carbon emissions of an electric car tends are around 17-30% lower.

In general, I do agree with the fact that electric vehicles are considered to be less environmentally impactful than gasoline vehicles. However, electric vehicles can also cause huge detrimental impacts on the environment. For instance, the magnets found in permanent magnet motors contain rare earth metals in which the mining process requires much energy and can release toxic compounds. Moreover, electric vehicles aren't truly zero emissions in many cases. This is because some electricity provided to electric vehicles comes from the burning of fossil fuels in a distant power plant making their pollution much higher than gasoline vehicles. But, overall, if advanced technology used in the future can solve these related issues, electric vehicles will be much better for the environment than gasoline vehicles.
