Electric vehicles are the future of mobility, but is Nepal ready?

By: Tsering Ngodup Lama
It was 2010 when Bijaya Sagar Pradhan bought his first electric car. Electric cars then were a rare sight on Kathmandu’s streets, making Pradhan one of the earliest adopters of private electric vehicles in the country.

“I was tired of waiting in long queues at fuel stations and I wanted to lessen my reliance on fossil fuels,” said Pradhan.

There has long been a plethora of choices when it comes to petrol and diesel-powered cars but Pradhan, in 2010, didn’t have that luxury. The only private electric vehicle--or EV, as they’re colloquially called--available then was the REVA, manufactured by a Bangalore-based company that has since been acquired by Mahindra. It was a small-sized car that could only seat two adults and two children.

“The car cost me around Rs1.2 million and it ran 80kms on a full charge. Since private EVs were a new concept for people in the city, many questioned my decision. Some even suggested that I should have added Rs200,000 and bought a Hyundai Santro instead. The less forgiving ones made fun of the size and design of the car,” said Pradhan.

For ECO Vision, the company that acquired the Nepal dealership for REVA vehicles in 2010, customers like Pradhan were rare.

“EVs were a novelty. Many didn’t know about EVs, and many who did, didn’t trust the technology,” said Pramod Bhandari, manager of the dealership. “Convincing people to opt for electric cars over conventional petrol and diesel cars was tough.”

During its initial years, the company, Bhandari said, considered one unit sale a month as a significant achievement.

Since Pradhan’s REVA purchase, Nepal’s EV landscape has undergone major shifts. The number of EVs in the country, including private two- and four-wheelers and public vehicles, reached 21,000 in 2017, according to the Electric Vehicle Association of Nepal (EVAN). In 2018, that number crossed 45,000. Today, around 10 percent of vehicles sold in the country are EVs.

This significant rise in the number of EVs follows a global pattern where more and more countries are pursuing policies that promote the adoption of EVs in private life and for public transport in order to combat pollution and climate change. In 2018, the number of electric cars in the world crossed 5.1 million, an increase of two million from 2017, according to the International Energy Agency, a Paris-based intergovernmental organisation.

To cater to the growing demand for EVs, a slew of dedicated international manufacturers--Tesla, Rivian, LUCID Motors, NIO and Byton--have sprung up. Even traditional combustion engine automakers have started focusing heavily on EVs. The German auto behemoth Volkswagen plans to produce 50 EV models by 2025 and sell one million electric cars every year between 2025 and 2030, half in China alone. In 2018, Ford announced plans for at least $11 billion of investment into EV production by 2022.

“The future of mobility is electric,” said Umesh Raj Shrestha, chairperson of EVAN. But for Nepal to transition fully to EVs, the country needs robust infrastructure to support these vehicles. And the time is here for Nepal to start laying the groundwork for what is certain to become the next grand transition in transport.

दिल्लीको वायु प्रदूषण मापदण्डभन्दा २० गुणा बढी

नयाँदिल्ली  : भारतको नयाँदिल्लीमा विश्व स्वास्थ्य संगठनले तोकेभन्दा प्रदूषणको स्तर २० गुणा बढेपछि अधिकारीले स्थानीय बासिन्दालाई सकेसम्म केही दिन घरभित्रै रहन र प्रदूषणका स्रोत मानिने गतिविधिलाई कम गर्न सहयोगी भूमिका खेल्न आग्रह गरेका छन् ।

दीपावलीअघि नै शहरमा बाक्लो तुँवालोले ढाकिएपछि यहाँका बासिन्दामा त्रास फैलिएको छ । दीपावली मनाउँदा पटाका पड्काइने भएकाले वायुको गुणस्तर झनै खस्किने ठानिएको भन्दै विज्ञहरूले पूर्वचेतावनी दिएका छन् । प्रदूषण कम गर्न शहरभित्र भइरहेका निमार्णकार्यलाई नियन्त्रण गरिएको छ । सबै विद्यालयहरूमा तीन दिन बिदा दिइएको छ ।

We’re just learning how exposure to air pollution degrades our brains

There are all kinds of impurities from industrial activities like manufacturing and transportation that can poison the air. The smallest seems to be the most sinister. Particles called PM2.5, which come from burning fossil fuels, including gasoline for transportation, are just two-and-a-half millionths of a meter or smaller in diameter, small enough to make their way from the lungs into the bloodstream. In 2015, there were 4.2 million deaths related to exposure to PM2.5 worldwide, the equivalent of more than 7% of all deaths that year. Over 95% of the global population is exposed daily to PM2.5 levels that the World Health Organization considers dangerous.

A growing body of evidence is starting to show that exposure to PM2.5 pollution is also tied to poor cognitive function in children and adults, and an uptick of dementia rates in the elderly.

वायु प्रदूषण वौद्धिक क्षमताका लागि हानिकारक

वायु प्रदुषणले वौद्धिक क्षमतामा ह्रास ल्याउने एक अध्ययनले देखाएको छ। अमेरिकी जर्नल नेसनले एकेडेमी अफ साइन्सले सोमबार प्रकाशित गरेको अमेरिका तथा चीनको संयुक्त अध्ययनमा वायु प्रदूषण वौद्धिक क्षमताका लागि हानिकारक भनिएको छ।

अनुसन्धानकर्ताले चीनका २० हजार व्यक्तिमा चार वर्ष गरेको यस अनुसन्धानले वायु प्रदूषणका कारण मानिसहरु गणितीय क्षमता तथा बोल्ने क्षमतामा ह्रास आएको देखाएको बीबीसीले जनाएको छ। अध्ययन अनुसार उमेर बढेसँगै वायु प्रदूषणको प्रभावले मानिसमा वौद्धिक क्षमतामा कमी हुँदै जान्छ।
अध्ययनमा भनिएको छ, ‘वायु प्रदूषणले विशेषगरी पुरुष, अशिक्षित व्यक्ति, वृद्ध व्यक्तिको वौद्धिक क्षमतामा ह्रास पु¥याएको प्रमाण छ।’ मुख्यगरी वायु प्रदूषणले मस्तिस्कसम्बन्धी रोग डिमेन्सिया, अल्जाइमरलाई निम्ताउन सक्छ।

The Weight of Numbers: Air Pollution and PM2.5

EMANATING FROM smokestacks, vehicle engines, construction projects, and fires large and small, airborne pollution – sometimes smaller than the width of a human hair, and very often the product of human activity – is not just contributing to climate change. It is a leading driver of heart disease and stroke, lung cancer, and respiratory infections the world over. Exposure to such pollution, the most deadly of which scientists call PM2.5, is the sixth highest risk factor for death around the world, claiming more than 4 million lives annually, according to recent global morbidity data. Add in household pollutants from indoor cooking fires and other combustion sources, and the tally approaches 7 million lives lost each year.

Is air pollution making you sick? 4 questions answered

Not a day seems to go by without a story of an “airpocalypse,” usually somewhere in a developing nation. It’s hard not to empathize with the people in the smoggy images of New Delhi or Ulaanbataar or Kathmandu, often wearing masks, walking to school or work though soupy cloudiness.

Last year, a study found that more than 8 million people per year die early from air pollution exposure. This amounts to more deaths than diarrheal disease, tuberculosis and HIV/AIDS combined. 
1. What exactly is air pollution?
Air pollution is a general term that usually describes a mixture of different chemicals that circulate in the air.

Invisible gases, like ozone or carbon monoxide, and tiny particles or droplets of liquids mix together in the atmosphere. Each molecule is impossible to see with the naked eye, but when trillions gather together, you can see them as haze.
