Mythbusting: "电动汽车s are no more climate-friendly than ordinary cars!"

The debate about how climate-friendly electric cars "really" are comes up now and then in newspapers and social media. 辩论的温度可能非常高. 有些人想禁止电动汽车, or at least remove all the benefits they enjoy in 挪威 – such as exemption from road tolls, 免费停车和在公交车道上开车的权利. The main argument is that the incentives do not correspond to the climate benefits, and that the production of electric vehicles requires so much energy that you might as well drive a fossil car.

挪威网站Faktisk的编辑人员.No已经驳斥了一个顽固的神话 electric cars produce twice as much greenhouse gas as fossil cars （挪威语网站文本）.

十大靠谱网赌问过维大艾德, 谁是Statkraft旗下移动出行公司Mer的首席运营官, 来看看其他一些关于电动汽车的常见说法.

关于电动汽车的一些神话和事实

1. “如果十大靠谱网赌关心什么对气候最好, we should spend money on carbon quotas instead of subsidising expensive electric cars."

答：电动汽车对气候最有利, and climate quotas do not solve the problem of emissions from vehicle traffic. 如果你现在买一辆新的化石燃料汽车, it will be in the car population for many years and "lock in" fossil fuel consumption and greenhouse gas emissions. There are also strong indications that the price of electric cars will fall significantly, which further weakens the argument that climate quotas are cheaper.

2. "电动汽车s require much more energy to produce than traditional cars, 特别是考虑到电池. 电动汽车s must therefore be driven longer before they can be considered zero-emission cars."

Answer: The production of batteries creates greenhouse gas emissions, but this is primarily because the batteries are produced in Asia and China. 那里的电力结构也在变得更加清洁. When we can eventually produce the batteries with electricity from renewable energy sources, 电池将不会产生“内置”排放物.

3. “挪威是欧洲电力市场的一部分. Therefore, we cannot say that we drive our electric cars on clean Norwegian hydropower. 十大靠谱网赌使用的电力也来自煤和天然气."

Answer: The electricity from wall sockets in 挪威 comes mainly from hydropower, 但既然十大靠谱网赌都在买卖权力, 有时可以用国外的煤发电. 然而, life cycle studies show that electric cars are more environmentally friendly than fossil cars, 不管动力结构如何.

4. "The batteries are an environmental time bomb because they cannot be reused. Many of them end up in landfill sites and contribute to polluting the environment."

Answer: 电动汽车 batteries will not end up in landfill sites – they are too valuable for that. 今天, the batteries often get a new life in the power system to support the phasing in of wind and sun power. After that it will pay to recycle them because they contain valuable materials.

5. "Increasing the number of electric cars increases the load on the power grid. More masts must be built and more powerful cables must be added to meet the demand."

答：电网可以轻松处理更多的电动汽车, especially when we can increasingly control when during the day and night cars are charged. Our need to strengthen the power grid stems not from electric cars, 而是从总体上增加电气化.

6. "People with electric cars stop using public transport and thus contribute to increased traffic overall."

答：我不确定, but it's clear that access to the bus lanes and reduced road tolls, 就像挪威一样, 能让电动汽车更吸引人吗. Over time, such benefits will disappear, and then more people will again choose public transport.

7. “买电动汽车的人通常有好几辆车, 因此，它们无助于减少汽车的数量."

Answer: More and more people have an electric car as their only car. There are probably some who previously only had one car who are now buying an electric car as well. And many who would have had two cars anyway, now have an electric car as the second car. In the short term this may result in more cars, but not necessarily more cars on the road.

8. "The production of car batteries is detrimental to scarce and non-renewable resources, 尤其是锂和其他贵金属. 这是不可持续的. "

Answer: It is not correct to say that batteries contain scarce resources. 钴和锂等金属在许多地方都有发现, but in the short term there will be a shortage because the need will grow every year. 然而, battery manufacturers are constantly working to reduce the use of the most expensive metals, and eventually we will get batteries with a completely different composition than today.

9. "电动汽车s create more particulate matter because they are heavier and cause more wear on asphalt."

答：车越重, 沥青磨损产生的颗粒物质越多, and electric cars are generally heavier than equivalent fossil cars. 另一方面, 电动汽车不会产生颗粒排放或发动机噪音, 化石燃料汽车有哪些重大问题.
