Alternative fuels, types, properties, advantages and disadvantages of each type of fuel

Alternative Fuels: These are options other than traditional gasoline or diesel that can power vehicles and
machinery.
Types

1 Electricity: Powers vehicles through batteries or fuel cells.
Properties: Clean, renewable, and can be generated from various sources like solar, wind, or hydro.
Advantages: Zero tailpipe emissions, lower operating costs, quieter operation.
Disadvantages: Limited driving range, long charging times, reliance on electricity grid infrastructure.
2 Biofuels: Derived from organic matter such as plants or algae.
Properties: Renewable, carbon-neutral, and can be blended with traditional fuels.
Advantages: Reduces greenhouse gas emissions, supports agricultural economies.
Disadvantages: Land use competition with food crops, potential for deforestation, may require large amounts
of water and energy for production.
3 Hydrogen: Used in fuel cells to produce electricity.
Properties: Clean burning, abundant, and produces only water vapor as a byproduct.
Advantages: High energy density, quick refueling, versatile applications.
Disadvantages: Costly production, limited infrastructure, energy-intensive to produce.
