The automotive industry is undergoing a significant transformation as it shifts towards more sustainable practices and cleaner renewable energy sources. The 140 years reliance on fossil fuel based automotive industry is contracting and new electric vehicles EVs are making their place being more sustainable in terms of running, performance and durability.
The current study highlights the evolution of Hybrid and Fully Electric cars Evs and how the advancements in renewable energy production has revolutionesed the automotive sector.
The Early Days of Automobiles
The first successful petrol-powered car was developed by Karl Benz in 1885-1886. It was a simple three-wheeled vehicle. Subsequently, the gasoline-powered internal combustion engine dominated the 20th century which marked the beginning of our dependence on fossil fuels for transportation. While this innovation was groundbreaking at the time, it actually set the stage for many of the environmental challenges we face today.
The petroleum thefore became the liquid gold and many under developed world economies took up a boom most specially in middle-east, central asia, and north America in 1960s.
Rise of Environmental Awareness and Evolution of Hybrid Automotive
The automotive industry faced a crucial turning point in 1970s with respect to relationship of fossil based energy with alternate energies. The 1973 Arab Oil Embargo led to soaring oil prices and gasoline shortages and therefore sparkled the worldwide interests in reducing dependence on foreign oil.
The crisis also prompted United States to initiate technological, social and financial integrations to reduce the reliance on fossil fuels, support the environmental protection moves, develop a more sustainable automotive for protection against any global political implications related to petroleum industry.
This resulted in passing of the Electric and Hybrid Vehicle Research, Development, and Demonstration Act of 1976 in United States, authorizing research into alternative fuel vehicles. During this period, all major automakers started exploring electric or at least electric and hybrid engines in the initial phase.
A significant milestone was achieved in 1996 when General Motors introduced the EV1, a purpose-built electric car. The EV1 offered a range of up to 160 kilometers with lead-acid batteries, later improved to 225 kilometers with nickel-metal hydride batteries. However, despite its technological achievements, GM ceased production in 1999, citing high costs.
later, many other companies in China, Japan and Europe also started making similar changes resulting in introducing of hybrid vehicles in Europe by Toyota. Modern hybrid cars industry was then significantly extended by introducing similar techonology by Honda, Mercedes, Hyundai, Ford etc in Europe and Asia.
Role of China in Modern Hybrid Automotive Industry
Electric cars were the largest category traded among the hybrid and electric cars in 2023 in China, a change from 2022, when non-plug-in hybrid cars were the main category. The top 3 countries from which the EU imported electric cars were China, South Korea and United Kingdome last year.
From July to October 2024, China exported 65,800 hybrid cars to Europe, which was more than triple the number exported in the same period in 2023. China's exports of passenger cars jumped almost 20% in 2024, to almost 5 million vehicles, contributing to a sharp rise in China's overall exports. China therefore now holds the status of world’s biggest exporter of hybrid cars to many other countries in 2024 which is expected to increase by 20% in 2025.
The Severe Environmental Effects and Evolution of Fully Electric Vehicle - EVs
Electric vehicles (EVs) are widely regarded as an environmentally friendly alternative to traditional gasoline- and diesel-powered vehicles and even hybrid vehicles. The most significant environmental benefit of EVs is their zero tailpipe emissions. Unlike internal combustion engine (ICE) vehicles, electric cars do not emit carbon dioxide (CO₂), nitrogen oxides (NOx), or particulate matter (PM) from the exhaust. These emissions contribute to increase in air pollution, especially in urban areas, where vehicular emissions are a major source of poor air quality.
On the other hand fully electric vehicles are also more efficient than gasoline, diesel-powered or hybrid cars. Electric motors can convert around 85-90% of the energy from the battery to move the wheels, whereas traditional engines typically convert only about 20-30% of the energy in gasoline into motion. This higher efficiency results in less energy consumption and fewer resources needed for transportation.
Currently, fully electric cars are being manufactured by major automakers now, including tesla, Ford, Volkswagen, Audi, Porsche, and Hyundai.
The industry's growth is projected to continue, with EVs expected to account for 46% of light-vehicle sales by 2025, growing to 68% by 2030.

Currently Lithium manganese iron phosphate (LMFP) batteries and sulfur batteries provide significant mileage sometimes provide 500 to 1000 miles.
With the anticipated advancements, EVs are to become more affordable, efficient, and environmentally friendly in near future.
Do EVs have Negative Environmental Impacts?
While electric vehicles (EVs) are generally considered to have a lower environmental impact as compared to conventional gasoline-powered vehicles, they have some negative environmental aspects also.
Lithium-ion batteries, widely used in most electric vehicles, require the extraction of raw materials such as lithium, cobalt, nickel, and graphite. The mining and processing of these materials can have significant environmental impacts, including habitat destruction, water use, and pollution.
Secondly, manufacturing EV batteries is relatively energy-intensive, and the carbon footprint associated with producing an electric vehicle can initially be higher than that of producing a traditional car, primarily due to the energy required to produce the batteries. However, this is not as significant keeping the vehicle's operational life in consideration, especially when the electricity used for charging is mainly being derived from renewable sources.
Although, electric vehicles themselves produce zero emissions, the environmental benefit depends on the source of the electricity used to charge them. In regions where the power grid is largely powered by fossil fuels (such as coal or natural gas), the carbon emissions already have significant impact. As the power generation are being integrated into renewable energy sources, the impact of charging EVs will continue to decrease.
There are more environmental and economic challenges when EV batteries reach the end of their life due to improper disposal and recycling. If not recycled correctly, these batteries can contribute to toxic fumes and wastes due to the chemicals and heavy metals inside.
However, advancements in battery recycling technologies are being made, and there are increasing efforts to develop systems for recycling and reusing EV batteries to minimize waste and recover valuable materials. Many EV battery manufacturers are now integrating their systems for more accurate and environment friendly recycling processes.
Some companies are also exploring ways to give EV batteries a second life after they are no longer suitable for use in vehicles and can be repurposed for stationary energy storage systems, such as storing solar energy, before they are eventually recycled.
As the demand for EVs is growing, there is increased pressure on global reserves of Lithium, Cobalt and Nickel required for battery production. However, researchers are working on alternative battery chemistries solid-state batteries or sodium-ion batteries which could reduce reliance on scarce or environmentally damaging materials.
What is the Positive Long-Term Environmental Outlook in EV Sector?
