Go green India: Revving up with alternative fuels!

Compressed natural gas (CNG) is a fossil fuel substitute for gasoline, diesel or propane/ LPG. It is mainly composed of methane and is stored and distributed in high-pressure containers and these vehicles operate much like gasoline-powered vehicles. Natural gas is stored in a fuel tank, or cylinder, usually at the back of the vehicle.

• •
  Reduced Emissions: Breathe easier! CNG vehicles emit significantly less harmful pollutants like carbon monoxide and nitrogen oxide compared to gasoline. CNG does emit some methane.
• •
  Cost Savings: Fill up for less! CNG is generally cheaper than gasoline and is fuel efficient. Sufficient Availability: No need to hunt for fuel! India boasts a growing network of CNG stations. And in case you run out of fuel, the vehicles automatically switch to petrol.

CNG vehicles have lesser boot-space, but manufacturers are addressing this in the newer models.

A promising alternative is emerging: CBG (Compressed Biogas): Made from organic waste, CBG offers even lower emissions and promotes waste management. Look out for more CBG stations popping up in the future!

Hybrid vehicles combine a traditional internal combustion engine with an electric motor to enhance efficiency and reduce emissions. In India, both mild and strong hybrids are available. Plug-in hybrids have not yet made an entry into the market.

• •
  Eco-Friendly Efficiency: Hybrids seamlessly switch to electric power, significantly reducing emissions a crucial benefit for the environment in today's scenario.
• •
  Fuel-Sippers: They offer superior fuel efficiency compared to traditional gasoline cars. Fill up less, save more, breathe easier.
• •
  Recharge on the Move: Every time you hit the brakes; it’s like a mini charge-up for your hybrid’s electric motor. This translates to less money spent on gasoline and a smaller environmental footprint.

Bumps to consider:

• •
  Higher Initial Cost: The upfront cost of hybrids is typically higher than gasoline vehicles.
• •
  Battery Concerns: The lifespan and potential replacement cost of the hybrid battery are important factors to consider. Researchers are exploring innovative materials that could make hybrid batteries lighter, cheaper, and last longer.

Choosing the right hybrid: Mild hybrids use limited electric power which does not reduce carbon footprint much, while a strong/ full hybrid runs on ‘EV mode’ for longer durations. While hybrids are the steppingstone towards a greener future, they're not the ultimate solution. The gasoline engine still contributes some emissions. However, considering the current state of charging infrastructure and India's energy mix, hybrids offer a significant environmental benefit and a smooth transition towards a cleaner tomorrow.

Electric Vehicles (EVs) are powered entirely by electricity stored in batteries. They use electric motors instead of combustible engines.

• •
  Zero Tailpipe Emissions: Breathe easy every time you hit the road! EVs produce no emissions at all, contributing to cleaner air, especially in bustling cities.
• •
  Silent Operation: Enjoy the peace and quiet! EVs offer a smoother and quieter driving experience, reducing noise pollution.
• •
  Lower Running Costs: Go electric, save money! Electricity is generally cheaper than gasoline.

The Not-So-Silent Partner: Electricity and Battery Concerns

• •
  While EVs themselves are emission-free, a significant portion of the electricity used to recharge comes from coal, which adds to the carbon footprint.
• •
  Environmental impact of the batteries: Manufacturing lithium-ion batteries can be energy-intensive, and their disposal requires proper recycling practices to avoid environmental hazards.

However, the future looks promising. Here's India’s aim* to address these concerns:

• •
  Achieve 50% cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030.
• •
  By 2026, aim to recycle and recover 90% of battery materials.
• •
  By 2030, expect 20% of these recycled materials to be used in creating new batteries.
