Energy Transition with Electric Vehicle Might Need to be Done Carefully

Hybrid versus Electric – Which are more environmentally friendly? The environmental impact of electric vehicles (EVs) versus hybrid vehicles depends on the source of electricity used to charge EVs. If non-renewable sources like coal or natural gas are used, EVs’ carbon emissions increase, despite their lack of exhaust emissions. Additionally, EVs require larger, more resource-intensive batteries, raising their initial environmental footprint. Over time, even when using non-renewable electricity, EVs generally produce fewer emissions than traditional internal combustion engine vehicles. However, they may not always outperform hybrids, especially when relying on coal-based power. Hybrid vehicles, which use both fuel and electricity, emit less than conventional fuel-powered vehicles but still release carbon dioxide when operating on fuel. Their smaller batteries have less environmental impact, and they tend to be more fuel-efficient. In the short term, hybrids may be more eco-friendly if EVs are reliant on electricity from fossil fuels. However, as the energy grid shifts toward greener sources, EVs are expected to become the better option for lowering overall carbon emissions. #hybrid #electricvehicle #sustainability #EV #environmentally #fuel #fms #electrician

🌍 INSIGHTS: How Electric Vehicles are completely outperforming traditional Internal Combustion Engine Vehicles 🚨 One thing that was probably the most eye-opening for me when I started my journey into the world of clean energy and electrification was how extremely inefficient traditional internal combustion engine (ICE) vehicles (Gasoline, Diesel, etc.) are in comparison to battery electric vehicles (BEV). Let's talk about numbers (tank to wheel efficiency): ➡ In ICE vehicles, only ~40% of the energy of fossil fuels can be used to actively propel the car forward (60%!!! is wasted as heat) ➡ BEVs boast an efficiency of 90% or greater, saving 50% of electricity/energy for useful use cases rather than expelling heat into the atmosphere Switching from inefficient ICE vehicles to BEVs not only demands less energy but also significantly reduces greenhouse gas (GHG) emissions over the entire car lifecycle (see article in the comments). Even when assuming a high carbon intensity grid with 600g CO2eq/kWh, which is still the case in a few countries, BEVs outperform ICE vehicles due to their superior efficiency. To put the number above into perspective, below are two more examples of the average grid carbon intensity in 2023 for: 1️⃣ Austria: 76g CO2eq/kWh 2️⃣ Europe: 255g CO2eq/kWh What about hydrogen some of you might ask? Well, even if we ignore the fact that ~99% of currently used hydrogen is still produced by fossil fuels, the total efficiency from source to wheel is also only ~30-40%, making it much less efficient than BEVs as well. There are some limited, legitimate use cases for green hydrogen, but in my opinion transportation is not part of it (neither for personal nor freight applications, except in some extreme scenarios). I'll create an additional post about this in the future. For further reading, I put some links in the comment section, including a great article by Paul Martin, a chemical process development expert with decades of experience who regularly publishes brilliant articles on all kinds of different topics related to a fossil fuel-free future. 📗 What are your thoughts on the topic?

🌍 **The Future of Internal Combustion Engines: Evolving or Receding?** As the world shifts towards sustainability, the fate of internal combustion engines (ICEs) is under scrutiny. EVs are rising fast, and stricter regulations are pushing us towards a zero-emission future. But is this the end for ICEs? While EV adoption is accelerating, challenges like charging infrastructure, battery supply, and energy grid demands make it difficult for EVs to fully replace ICEs—especially in heavy-duty transport, remote locations, and high-performance vehicles. However, ICEs have evolved with alternative fuels and hybrid technologies, keeping them relevant in specific applications. 🚀 **The solution? My innovative engine design.** With higher efficiency, reduced parts for easier manufacturing, and adaptability to various fuels, my engine can play a key role in bridging the gap between traditional ICEs and future technologies. It's designed to address environmental challenges while maintaining power and versatility, making it ideal for industries like aviation, shipping, and construction—where electric solutions are still out of reach. Let’s work together to create a sustainable future without losing the powerful benefits that ICEs bring to essential sectors.

The text in the image below is being shared widely on social media. I believe such viral images to be part of a misinformation campaign being being waged by traditional automakers and the fossil fuel industry to prevent their inevitable decline. The text in the image presents a hypothetical scenario where internal combustion engines (ICEs) are considered a new invention after electric vehicles (EVs). While the author suggests that ICEs would be revolutionary, several scientific facts contradict this: 1. Efficiency: Electric vehicles are inherently more efficient than internal combustion engines. ICEs convert only about 20% of the energy stored in gasoline to power at the wheels, while EVs can convert over 77% of the electrical energy from the grid to power at the wheels. 2. Emissions: ICE vehicles emit greenhouse gases such as CO2, contributing to climate change. EVs have no tailpipe emissions. While EVs do have a carbon footprint from electricity production, this is generally lower than that of ICEs, especially as the grid becomes greener. 3. Maintenance: ICEs have more moving parts than EVs, which often leads to higher maintenance costs over time. EVs have fewer parts that could fail and do not require oil changes. 4. Resource use: Although EVs require rare earth elements for batteries, the overall environmental impact, including the extraction of oil for fuel, generally favors EVs. Advances in battery technology are reducing the dependence on rare earth elements, and recycling programs are becoming more prevalent. 5. Refueling time: While it's true that refueling an ICE vehicle is quicker than charging most EVs, the convenience of home charging for EVs and the rapidly increasing charging infrastructure, along with fast-charging technology, are making EVs more practical for many users. In summary, when considering the full lifecycle analysis, including production, operation, and disposal, EVs currently offer a more sustainable alternative to traditional ICE vehicles. This is why the transition towards electric mobility is being encouraged worldwide as part of efforts to reduce carbon emissions and combat climate change. #Positive #Facts #Sustainability #Renewables #ElectricVehicles #Oil #Gas #Environment #ICE #Mobility
